First, when posting code, please keep it short and to the point. Posting
every bit of your code will just make people's eyes glaze over and they'll
just ignore all of it.

To your problem: when you get your text from the EditText, it should not be
going directly to some TextView - it should be going to the data structure
that your ListView items represent. Then you invalidate your adapter and
your list gets updated.

It should, but I suppose you could be doing something wonky in your adapter.

You're specifically asking for last known location. If that's not what you

Also, you're duplicating a ton of code. They're called "functions" ;-)

[android-developers] Re: Odp: SoundPool and DualCore (Samsung Galaxy S2) : Random Crashes ingame

2011-07-16 Thread Daniel

I have been getting reports of S2 crashes too... and based on this thread, 
and since i use SoundPool extensively, i'm pretty confident at this point 
that it is the cause.
Has anyone been able to try native OpenSL ES audio, and seen better results? 
(Haven't got round to setting all that up yet since 2.3 adoption has been 
pretty slow). I guess it will depend on whether the problem is with 
SoundPool specifically or the lower level drivers.

[android-developers] Re: How to lock current orientation at runtime?

2011-07-16 Thread Brad

Dianne, thanks for the response - you're probably right, I should just
bite the bullet.

I'd like to vent a little though about what a hassle it is to deal
with orientation changes.   It must be the #1 source of bugs in the
apps that I've come across (including my own apps).   iOS does a lot
of things wrong, but it makes orientation changes so much easier than
Android.   I still haven't found a way to preserve the state of an
activity that launches another dialog style activity that gets an
orientation change - I end up shoving everything in the db or passing
the state data to the dialog class.   I'm no guru so I'm probably
doing something wrong there, but I wish to God that we could go back
in time and come up with a better way to deal with orientation changes
that didn't involve killing and reconstructing the entire activity!

Ok, done w/the vent.  Having said all that I still enjoy programming
for Android more than Apple even though I sell a lot more apps on the
App Store vs the Market :-)

Re: [android-developers] How to lock current orientation at runtime?

2011-07-16 Thread Dianne Hackborn

Those are two different orientations.

The Configuration constants:
http://developer.android.com/reference/android/content/res/Configuration.html#ORIENTATION_LANDSCAPE

The constants for set/getRequestedOrientation():
http://developer.android.com/reference/android/content/pm/ActivityInfo.html#screenOrientation

Beyond that, I would strongly recommend not doing what you are trying to do.
 This would result in a UI flow that is very counter to what the user
expects -- that either an app is going to run in a particular orientation,
or allow them to rotate their screen as they would elsewhere.  Ending up
locked into whatever orientation they happened to launch the app in is just
not how things should work.

Besides which, there are all kinds of edge cases you'll never get right --
for example what happens if they press home to leave your app, rotate their
device, and then task switch back to your app?  Or as another poster
mention, if you lock the screen into portrait like this and they flip the
lid on their keyboard the orientation won't change to landscape, which is
not what they are going to want.

You really, really just need to code your activity correctly to be able to
destroy and re-create the activity.

[android-developers] Re: Recent developments regarding Android (HTC) patent infringement lawsuits

2011-07-16 Thread Howard M. Harte

In the past, I have worked as an expert witness in several patent
litigation cases.  What happens is that the law firms involved will
hire expert witnesses to do research on these patents, and try to find
prior art that invalidates the patents.  If the prior art is strong,
then the plaintiff may drop the case or try to settle out of court.
If the case actually gets litigated, then the patent may become
invalidated, and then could not be asserted against another party in
the future.  This is a big risk, so usually, the case will be settled
out of court.

Patent examiners have a limited amount of time to examine a patent
when it is filed, so many if not most patents will not be able to
withstand the scrutiny of several expert witnesses spending hundreds
or thousands of hours searching for prior art.

In short, it is very easy to get a patent granted, and it does not
mean much until that patent is actually challenged in court.

One technique that I often used to find good prior art was to look at
the patents cited, then look those patents up and see what they cite.
It takes a lot of time, but the more time you invest, the more likely
you are to uncover something missed by the original patent examiner.

It also takes a lot of money, which is why this is a game for big
players with deep pockets.

But of course I am not a lawyer, and this just my personal opinion
having seen a little of how these things play out.

Re: [android-developers] How to lock current orientation at runtime?

2011-07-16 Thread Nick Risaro

If you add android:configChanges="orientation" to your activity in the
manifest then the method "onConfigurationChanged" of your activity will be
called, here you can decide what to do with the change, but most important,
the activity will not be restarted.

You can check this
http://developer.android.com/guide/topics/resources/runtime-changes.htmlwhere
it's better explained.

Assuming you lock the orientation, how will you prevent the user from

Less plausible, but possible as well, from changing the phone's configured

Except that it didn't work.  :-(

Oh well, I solved it:  I put a note in the Usage page saying that,
depending on your Android device, the scroll feature may not place
the first entry for the malting company you select on the top of
the screen, and added that my Motorola Bravo puts it on the bottom,
and nobody seems to know why.

I also added a comment for users of devices below Android 2.2 that
the scroll feature won't work at all, because it didn't exist until
2.2, and they will always end up on the first entry in the list.

Now all I have left to do, after spending a lot of time on it today,
is figure out how to configure it as a paid app, and then build the
free version,  which will have about 15[1] of the 297 (+/-) entries
(the others will create a Toast that, like the added text in the main
index says, those are only in the paid app)..  But none of that is
going to happen tonight...I'm taking the rest of the night off!  :-)

Later,

[1] about 15 ... basically, the basic malts that are most commonly
used, and only the generic data

[android-developers] Re: Install % not updating?

2011-07-16 Thread JonFHancock

I've been having a serious reduction in sales since July 1st.  For me
it is because Market search is horribly messed up.

My active install rate has been going up, but my ranking keeps falling
in search terms that I've dominated for a year.

Oddly though, I have moved up from about 170 to 159 in top paid apps
on the market.  I'm kind of guessing that all of my immediate
competitors in that range are losing revenue too.  If they were
staying the same, then I should be dropping.

Zsolt, I'm with you.  This is my only income source, so I've been
swinging from fits of rage to depression.

I've been in contact with a product manager on the Market team, and he
keeps telling me that they are working on it, and I will see a fix
soon.

I've seen the crashes in Checkout too, but only with orders from Japan
that were cancelled by Google for invalid credit card information.

[android-developers] How to lock current orientation at runtime?

2011-07-16 Thread Brad

Hi,

I'm trying to lock my activity to the current orientation to prevent
an orientation change from restarting my activity while I'm waiting
for a http response.

So I'm trying to use this:

setRequestedOrientation(getResources().getConfiguration().orientation);

And it works fine for portrait (orientation == 1), but when the device
is in landscape it's getting a value of 2 which ==

ActivityInfo.SCREEN_ORIENTATION_USER

And this doesn't lock the screen.

Does anyone have any idea why I'm getting this instead of LANDSCAPE?
Any suggestions for a better way to lock the current orientation?

Thanks!

Re: [android-developers] Android SDK Courses

2011-07-16 Thread Kristopher Micinski

I think Mark Murphy does Android courses, he also puts out a book which
covers a lot of what you'd like to know (or so I've been told®).  You should
check with him, he's on the list and regularly answers questions.

(Mark probably might not feel appropriate plugging himself, but I can.)

[android-developers] Aw: Re: Asmack Packetlistener + UI Update = Threading Problem ?

2011-07-16 Thread tuxfusion

Hi ,
I thought I'd get at least a mail if I get a reply :)

I solved this issue, the main things were : 

   - make sure mHandler.post() ( replaced runOnUiThread  ) references UI 
   thread by being instanciated in onCreate()
   - the handling of incoming packets was correct, however, I send out the 
   reply in yet another thread ( xmpp result for the IQ), so in many cases the 
   replay thread was faster then the gui or the other way round. So i just 
   added :   "connection.sendPacket(reply);" in the same .post(...) part where 
   the I manipulate the GUI and when that finishes reply gets send and the 
   sending client receives the reply and sends the next package, but not 
   sooner.
   
Regards

[android-developers] Re: Option to unlock the boot loader for Sony Ericsson Android Gingerbread phones now available.

2011-07-16 Thread Ryan A

Hello, Im sure you have been asked this question many times already but like 
a lot of other Verizon CDMA Xperia Play owners, I am checking the web, 
forums, and other places each day in hopes to finally see an unlock for our 
bootloaders so root can be acheived. I am on my 3rd Xperia Play and am 
having a very hard time enjoying this phone. My first 2 went defective with 
different issues after a week or so. While the current "Play" that I am 
using doesnt have any hardware issues like the others, the software 
glitches, spotty wifi, and horrible lag makes it such a dissapointment and I 
truly see so much potential. Without being able to unlock bootloader soon I 
see no reason to keep this phone much longer. Im not alone. Please tell me I 
can look forward to a solution soon?? Thanks, Ryan

[android-developers] word suggestion for ~,#,- etc not done properly

2011-07-16 Thread Sri Kommareddi

Hi,

Issue :In Browser text box '~' sign is not getting deleted by using
backspace key on first attempt

This happens to some types of text input element on web page. If the
word suggestion is On, this issue will be seen for character
'~','#','-'.

my hardware has qwerty keyboard, the input method is different from
virtual keyboard. The characters '~','#','-' have special meaning for
word suggestion in this qwerty input method.

I think when enter "~", the word suggestion is not done properly. Any
suggestions to resolve this issue ?

Thanks
Sri

[android-developers] Re: emulator problem

2011-07-16 Thread stevejbrot...@gmail.com

Lemme EXPAND on the answer that Chrystian didn't explain...

I don't know about Linux and Macs Operating systems, but you need to
change to the short 8.3 format path (eg. the old MS-DOS 6.22 path) on
Windows.

In Eclipse, go to menu bar and click "Windows" -> Preferences and on
the left side, select "Android".

On the right side of menu near the top where it says "SDK Locations"
**AND** if you kept the default path during installations, change it
to this:

for 32 bit Windows 7 -- (C:\Program Files\Android\android-sdk)
C:\PROGRA~1\Android\android-sdk

For 64 bit Windows 7 -- (C:\Program Files (x86)\Android\android-sdk)
C:\PROGRA~2\Android\android-sdk

HOWEVER, if you changed the SDK path during the installation, then you
need work it out on your own. Best to go through a DOS window and use
dir /x to work out the short names.

There was another alternative discussed by creating a link using
MKLINK command. It might be worthwhile to investigate.

[android-developers] Setting the text in Android Textview in external xml file

2011-07-16 Thread Árón

I'm trying to set the text in a TextView that is found in a layout xml
file that is not the layout file used as the setContentView for my
activity. The layout file that the TextView is located in is a sub
layout file used to populate a list item with database information for
a ListView in the main layout file.

When I use the code below to call the TextView I'm getting a null
pointer error as I realise now its looking in the parent Layout file
where it doesn't exist. How do I go about calling it from the sub
layout file?

TextView currency = (TextView) findViewById(R.id.currency);
currency.setText(cur);

Thanks A

[android-developers] More fixes for NFCDemo sample in 2.3.3...

2011-07-16 Thread Chuck

Hi,

I have looked at previous post and I fixed two major issues in the NFCDemo 
(The library issue and the Manifest problem). The automatically generated 
files still do not generate inside of eclipse. Is there a guide somewhere on 
all of the fixes needed to get this fixed. Also does anyone know if the 
Netcom MicroSD NFC card will work with this demo if I modify the technology 
profile in the Manifest file??

Thanks

[android-developers] Re: Send dtmf tone on uplink

2011-07-16 Thread Brian @ SPG

I just put out a inquiry on this just a few days ago and was also told
it can't be done.
I made some mp3 files of the various DTMF sequences I wanted - which
play nicely when I press the buttons on my app - but it doesn't go out
to the other end.
You'd think this would be possible.
Several years ago, I tried inserting DTMF via the headset jack of a
conventional cell phone, but the vocoder mangled it such that it
couldn't be detected at the other end.

[android-developers] error: device not found suddenly...

2011-07-16 Thread wan

Hi Android experts.. I desperately need your help.

I was able to upload my apk file to my Samsung GT-I5801, firmware
version 2.1-update.
I did not do anything to make it work (it is MAC book) other than at
phone -- Setting * Application * Development -- check USB debugging.

Thereafter I run
adb -d install -r ./bin/nicetrip-debug.apk

Until one time, I changed my phone's SIM card, and since then above
adb command will always give me below error

error: device not found


Is there any suggestion how to debug or fix?


Thanks,

[android-developers] Android findViewById() problem

2011-07-16 Thread Árón

Hey guys the main layout xml file for my activity is
R.layout.date_list_layout as it is used as follows

 public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.date_list_layout);

However I wish to set the text in a TextView from this same activity
in another layout xml file R.layout.display_item

I know I would usually use the code below but this is not working as
the R.id.currency TextView is not in the main
R.layout.date_list_layout

TextView currency = (TextView) findViewById(R.id.currency);
currency.setText(cur);

I know the next line of code is incorrect but is there a way to write
a similar line of code to access the R.id.currency in the
R.layout.display_item xml or can this not be done?

TextView currency = (TextView) findViewById(R.layout.display_item/
R.id.currency);
currency.setText(cur);

Some help would really be appreciated as this has me boggled the last
two days and I can't find any solution online

Thanks A

2011-07-16 Thread Jake Wharton

I managed to fix these up fairly easily. I can only assume the removed 
styles were not meant to be public yet and that the styling of action modes 
is being limited to provide a more consistent experience.

The missing attributes definitely need to be on the API differences report 
at the very least.

Re: [android-developers] Point2D.distance?

A search for Point2D in the SDK docs didn't turn up any classes that are 
supported by Android...


 which is not surprising, because Point2D is an AWT class, and 
Android has no support for AWT.


FWIW, distance is sqrt (dx^2 + dy^2), I assume that's common knowledge.

If you have lotsa code that has references to Point2D, you can just 
declare your own namesake class.

[android-developers] ActionBar/Mode Style Regressions with SDK 12r2 and 13r1

2011-07-16 Thread Jake Wharton

I develop a library  which attempts to allow 
for the use of the action bar design pattern on pre-3.0 versions of Android 
using the 3.0+ API via a support method (much like the compat library on 
which it is based). In order to provide the ability to use a single theme 
that can be applied across both the native and custom action bar widget 
implementations, I rely on duplicating all of the action bar and action 
mode-related theme attributes to non-android prefixed versions. This will 
let the custom implementation refer to them directly (e.g., 
android:layout_height="?actionBarSize") and the styles in values-v11/ to map 
them back to their native theme attributes (e.g., ?actionBarSize).

With the introduction of the 12r2 and 13r1 SDK it would seem a few of the 
theme attributes have changed as well as the visibility and name of other 
styles has changed completely (as in the old versions are gone). Namely,

   - Attribute: android:actionModePopupWindowStyle
   - Attribute: android:actionModeStyle
   - Style: Widget.Holo.ActionBarView_TabBar
   - Style: Widget.Holo.ActionBarView_TabView
   - Style: Widget.Holo.ActionBarView_TabText
   - Style: Widget.Holo.Spinner.DropDown.ActionBar
   - Style: Widget.Holo.PopupWindow.ActionMode

The result of these changes is that applications which implement my library 
no longer display any style for list or tab navigation. This is a very 
serious regression in the eyes of other developers who have chosen to use my 
library.

The API differences report for 13r1 notes that tab-related styles have been 
added in form Widget.Holo.ActionBar.Tab___. Does this mean that the 
Widget.Holo.ActionBarView_Tab___ styles were never meant to be consumed 
publicly in in 3.0r1 and 3.1r1? If this is the case, why then were they 
featured on the Android 
blog?
 There 
is currently no API differences report for 12r2.

In poking around the themes.xml included with the 13r1 SDK the two 
attributes listed above are included but reference to them will always give 
you a compile error. Even switching my build platform to 11r1 (the folder 
contents of which has not been updated since February 22nd) produces this 
error.

For a demonstration of this, you can look at the aforementioned styled 
sample which has been compiled using my library:

QR/Link:
Note that the tabs no longer get touch events when their text is clicked on 
directly. If you change the navigation mode to list you'll see that the 
dropdown no longer operates as expected and reverts to a modal list dialog.

I guess my question is why hasn't the change in these attributes and styles 
been documented in the API differences report? Why are attributes that seem 
to be defined in the platforms themes.xml (e.g., android:actionModeStyle) 
and styles.xml (e.g., Widget.Holo.Light.Spinner.DropDown.ActionBar) 
producing compile errors?

Re: [android-developers] Re: Install % not updating?

2011-07-16 Thread Adam Ratana

Looks like the checkout thing seems to be crashing on orders that have been 
cancelled in a certain way, or something, not just the Docomo, it happens 
with some older cancelled orders now too.  They are clickable, so it's 
possible to move to archive (or back to inbox) on each crashed one to then 
see others.  A workaround, but not ideal though.  Checkout Orders Page 
completely crashes on Tablet and Phone browsers though, can only really see 
the checkout orders page from a desktop browser - haven't found a workaroud 
yet, if others can also report this issue if you encounter that, hopefully 
action will be taken soon.

The market wackiness is a little frustrating, I'm small potatoes though; I 
can only imagine how it may be affecting people who depend on sales from a 
consistently working market.

Re: [android-developers] Re: List View and Simple Cursor Adapter


It's called as many times as ListView sees fit.

FWIW, I've also seen getView called more times than the number of 
visible list items (about 2X the number).


Don't worry about it - just make sure your getView does the right thing, 
based on the item's "position".


Also don't assume a one to one mapping between items and their views. 
Specifically, don't try to create some kind of secondary data structure 
back-mapping the items to their respective views.

This, of course, is the best answer. Constantly updating an app widget

Call cancel() on AlarmManager. Then call setRepeating() on AlarmManager.

Which means the above cancel() and setRepeating() calls go in the
onReceive() of OnAlarmRecevier, or possibly in an IntentService that
is started by onReceive() of OnAlarmReceiver.

Sure there is.

onReceive() of OnAlarmReceiver needs two pieces of information:

-- the time when the state should change
-- what the new state is

where by "state" I mean the new alarm period, how long it should
remain on that period, etc. Just a classic state machine.

You can either attach that information as extras on the Intent you use
with the PendingIntent for the alarm itself (in which case onReceive()
gets those extras off the supplied Intent), or you store that
information in a file/database/SharedPreferences and read it in in
onReceive().

Okay no problem.

>When the alarm period changes, have your alarm-handling logic cancel the

Okay but this is my question, how do I do this? My AppWidget's Button
fires the below logic when it is pressed.

AlarmManager mgr =
(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, OnAlarmReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
mgr.setRepeating(AlarmManager.ELAPSED_REALTIME,
SystemClock.elapsedRealtime(), 1000, pi);
mgr.cancel(pi);

There is no way to detect when the alarm period should change because
there is no way to communicate between the Alarm's fired function and
the AppWidgets non-existent state.

The only way you are going to have that data available is just like Mr. 
Murphy said... you need to store it.

Because using a file and using DB would be extreme overkill IMO I would look 
into using SharedPreferences

Hopefully, you are using an IntentService with this, since you cannot
reliably do network I/O from an AppWidgetProvider (which, under the
covers, is a manifest-registered BroadcastReceiver).

No, AlarmManager is your only choice. Either use that or don't bother
with this feature.

Update your app widget's RemoteViews when the alarm goes off. When the
alarm period changes, have your alarm-handling logic cancel the
existing alarm and schedule a new one.

[android-developers] Re: Weird java.util.Timer behavior in App Widget

2011-07-16 Thread cathal coffey

Mark,

thank you for your answer, especially on a Saturday.

Let me explain exactly what I am trying to do. Perhaps it is against
the SDKs ethos and that's why my simple task seems so difficult to
implement using the Android SDK.

I have an AppWidget with one button. When this button is pressed the
AppWidget makes a call to a web service and displays the returned
result on a label. This I have done and it works great.

What I am currently trying to do is add a second label which displays
the "freshness" of this data: seconds old, minutes old, hours old,
etc.
This would seem like a very common scenario. I can think of 5
AppWidgets --off the top of my head-- that I want to create that will
require this exact same mechanism.

Can you help me create this mechanism? You have already explained that
a Timer and TimerTask is not the correct approach. It also seems like
the AlarmManager is not going to work. You seem like an Android
expert, can you help me achieve my goal?

Cathal

AFAICT, that is in violation of the terms and conditions, though you
should discuss this with qualified legal counsel.

If you do not wish to abide by the terms and conditions, use another
mapping technology (e.g., Open Street Map).

There is no such concept in Android as "external sd path".

No, that is external storage. External storage does not mean "can be
physically removed by the user without requiring a soldering iron".
External storage means "can be mounted as a drive or volume on a host
machine when the device is connected via USB".

> The real sd path is /mnt/external1 but I can't get it from the Api.

There is no API to get an "sd path". Device manufacturers will declare
something to be external storage. On older devices, this tends to be
an SD card. On newer devices, this tends to be on-board flash. Newer
devices with external storage as on-board flash may also have some
form of SD card slot; there is no API means of getting a path to that
SD card slot or determining its state (e.g., is there media in it).

> Is it a bug in Xoom firmware?

No.

Use a file. Or a database. Or, conceivably, extras on the Intent you
use with the alarm. The first two would be simpler to code but will
involve disk I/O, which ideally is not performed on the main
application thread (where onReceive() and onUpdate() and such are
called).

If "MyWidget" is a subclass of AppWidgetProvider, there is no instance
when your alarm goes off. An instance of MyWidget will hopefully live
for less than a millisecond, during your onUpdate() processing (and
any other app widget lifecycle methods you elect to respond to). Once
onUpdate() returns, that MyWidget instance is gone, until the next
onUpdate() call when a new instance is created.

Any data that you have that is supposed to persist beyond a single
onUpdate() call must live someplace else, such as a file, database,
etc.

Hi,

Can somebody explain something about Xoom?

I would like to get external sd path but it returns the internal
storage as
/mnt/sdcard

The real sd path is /mnt/external1 but I can't get it from the Api.

Is it a bug in Xoom firmware? I have Android 3.2.

[android-developers] Re: Weird java.util.Timer behavior in App Widget

2011-07-16 Thread cathal coffey

Mark,

I think you miss understood what I mean by a reference to my Widget.

Unless I am thinking about this incorrectly. The function  onReceive
in the  OnAlarmReceiver class needs to have a reference to the widget
instance, see the below code. How else can the OnReceive function know
how many times it has fired and change its firing rate accordingly?

public class OnAlarmReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
MyWidget myWidget = SomeMagicFunction();

// Check myWidget.count to see how many times this alarm has 
fired.
if(myWidget.count == 60)
{
// We no longer want to fire once a second, we
now want to fire once a minute.
myWidget.alarmManager.cancel(myWidget.pi);

myWidget.alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME,
SystemClock.elapsedRealtime(), 1000 * 60, myWidget.pi);
}
}
}

I have two questions.
1) Is this the correct approach? If not then what.
2) If so then how do I do the following MyWidget myWidget =
SomeMagicFunction()

Kind regards,
Cathal

Seriously, if this isn't a joke, well, it is a joke.  EVERY computer
in the world matches these descriptions in one way or another.  They
all have a processor, memory, and some sort of programs which control
their actions on something.

Wham.  Ok, everyone...time to trade in your computers, GPS units,
phones (sorry, but even an old POTS phone connects to the local
telco, where they have digital switches that clearly have an input
and output, a CPU and memory, and programming which acts on an
item (subscriber calls).  You must replace them all with bricks.

EVERY modern cell phone is toast, according to what I just read.

This is also happening on the new phone version of Market. 'What's new'
is displayed in one language, the description in another. Sometimes, if
you are lucky, both are displayed in the same language. The whole
silliness with reordering comments based on some unknown 'usefulness'

Ok, I just added that, and it sort of worked, but not really.

I selected (continuing with the example) Crisp (UK) as the brand
to move to.  After it took me to a VERY wrong position, I added
some Toast

  position = 75 first = 0

where:
   position is the target position for the first entry for Crisp,
   first is the value from mainlist.getFirstVisiblePosition();

So apparently, FirstVisiblePosition isn't the first VISIBLE
position, but the first in the entire ListView.  :-(   That makes
absolutely no sense to me at all.  But at least I now have some
other possibilities to play around with (in the expanded "Inherited
Methods" list.  Thanks for telling me about expanding that---I'd
never noticed that it was a whole collapsed section.  I thought it
was the title for the next section that followed.

So I'll be back later, either with what worked, or more possibly
stupid questions.  :-)

It's already set up similar to that.  If, for example, you look
at the very top, you'll see the following:

   .-.
   | Briess (US) 2 Row   |
   |_|
   | Briess (US) 6 Row   |

   | Briess (US) Ashbourne Mild  |
   |_|
   | Briess (US) Barley Flakes   |
   |_|

and so on.  So it's obvious enough which brand any row is for.
I just don't like the idea of a user selecting a given brand from
an index, and instead of them seeing the first entry for that
brand on the top, having it show up on the bottom, like this
example, where the selected brand is Crisp (UK), and the code
instructed the ListView to scroll to the position for the first
row for Crisp:


   .--.

Those methods are on AdapterView, an ancestor class. Click on [Expand]
on "Inherited Methods" in ListView to see them on the ListView page.

[android-developers] Spinner usage

2011-07-16 Thread Simon Platten

I've used a spinner with a Base Adapter.  The spinner works fine and I can
make selections, my question is:

When I'm not making a selection the spinner shows as an empty box with a
down arrow, once I've made a selection the list is removed but the spinner
still shows empty, shouldn't it show the current / last selection ?

The XML for my spinner looks like this:



The ivFolder looks like:


http://schemas.android.com/apk/res/android";
 android:layout_width="fill_parent"

 android:layout_height="?android:attr/listPreferredItemHeight"
 android:padding="10dp">



Thank you,

Yes, when I said "row 42" I did mean the row at position 42.
And you are correct, I haven't added any headers or footers.
And row, ummm, excue me, position 42, is just a hypothetical
row number/position/whatever.  It could be anywhere from 0 to
297 (or was that 296?  I can't remember off-hand.)  42 was just
a randomly-selected example position.

Interesting.  A search on that in the dev guide leads me to
ListView, where, unless I missed it again and again, it isn't
even mentioned.  :-)  So let me see if I have this right, without
referring to the dev guide (which usually seems to produce much
better search results for me these days)

I have a ListView; let's call it myList.  I would use something
like:

   topidx = myList.getFirstVisiblePosition()

to find out what the position/row number is on top of the screen.

If it's the one I want, I'm done.  If not, move the one I want up
by the difference, and double-check, adjusting again if I missed
by one.

Have I got that right?  If so, that's exactly what I need to
solve all of this.  If not, what did I miss?

Since you wrote the plug-ins, fix the misbehaving threads. You should
not load arbitrary third-party plug-ins into your own application, due
to the security issues outlined by Mr. Stratton.

Beyond that, I know of no reliable way to forcibly stop a thread that
refuses to cooperate. I do not know what ordinary OSGi hosts do in
this case -- I'm not aware of Android threads being significantly more
difficult to stop than are Java threads on regular Linux.

Re: [android-developers] how do I highlight (color) a range of entries in a ListView?

I've not messed with ListView at all so I may be way off here...

I was thinking, could you put a smaller non-interactive row with 
the manufacturer name denoting where that particular manufacturer starts for 
each set of manufacturers. Similar to how the settings preferences are 
displayed.

[android-developers] Re: Killing rogue plug-in threads within an Android application

2011-07-16 Thread DCA

Thanks for the insights, Mark.

Am I right in assuming that there is no way to forceably stop a
misbehaving thread within an Android application short of killing the
process that owns the thread? My problem is that I'm loading java-
based plug-ins (not ARM binaries) into my framework dynamically (using
OSGi) and running each plug-in on its own thread. My framework
configures, starts and holds a reference to each plug-in thread;
however, if a plug-in misbehaves (i.e. keeps running even when told to
stop), my framework is unable to forceably kill the thread its running
on. Deprecated Thread methods for this purpose (e.g. 'stop') are not
implemented in Android, so I seem to be left with flags and
interrupts, which can be easily ignored accidentally or on purpose.

>From what you wrote, it might be possible for me run my framework in
one process and my dynamically loaded plug-ins in a second process.
That way, if I need to kill a misbehaving plug-in, I could kill the
second process, mark the plug-in as problematic, and uninstall it
prior to restarting the second process. Of course, this is a
heavyweight approach, and it would be much simpler if my framework
could simply forceably stop a misbehaving thread. Any ideas or tricks
in this regard?

Cheers,
DCA

I've never done this, so this is very rough. YMMV. Also, I am assuming
that 42 is a position and that you have no headers or footers on the
list.

Step #1: Confirm that 42 is in the range from
getFirstVisiblePosition() to getLastVisiblePosition(). Do something if
it's not.

Step #2: If it is, subtract 42 from getFirstVisiblePosition() to get a
child index.

Step #3: Call getChildAt() to get the row View at the specified child index.

Step #4: Use stuff like getX(), getY(), etc. to find out where that View is.

Re: [android-developers] how do I highlight (color) a range of entries in a ListView?

Ok...seems like this is getting WAY too over-complicated for what
should be (and probably is) a very simple task.  So let me
re-state the question in a different way, using an added bit that
I just realized must be possible, if there IS a way to position
Toast over a row that is on the display, but not where it was
expected to be  (i.e., to do that, you have to be able to
determine the row's location on the screen from the code.)

So, here goes.  How, from the code, can I determine the exact
location (top of display, bottom of display, specific point in
between on the display, ec.) where row 42 (or whatever) is at?

Once I know that, I can simply move up or down by the appropriate
number of rows to move the target to the top of the display.
Or, if all I can determine is that it's not on the top, I can
move up, check, move up, check ... repeat until the target IS
on the top of the display.

Thanks,

That ?might? work on an emulator, but will not on a properly configured

Please note that anything run in your process, or for that matter in another 
process run as your application's user ID will have the full privileges of 
your application.  Should the untrusted code cross the boundary from 
unintentionally misbehaving to malicious, it can do anything the system will 
permit your application to do, and to it in _your_ name.

Web browsers typically solve this problem for javascript by sandboxing the 
virtual machine in which the foreign code runs.  But that's not perfectly 
secure.  

Android solves the problem not by sandboxing the VM's in which applications 
run, but by using unix user ID's to separate the services the kernel 
provides to each application; you are proposing effectively to break down 
that mechanism and trust everything running at the invitation of your 
application by running it all under the same user ID.  Once you do that, 
existence of user-level administration and debug authority of all of a 
user's processes means running in the same or separate processes is just a 
convenience, not a true barrier.

You can try to pull that off via setGravity() on the Toast, but I

It has nothing to do with ListView, per se. Add your marker to your
row layout. Configure the row marker in getView() to be marked/clear
as needed. When your range changes/is gone, call
notifyDataSetChanged() on your Adapter to force getView() to be called
again for the visible rows, if needed.

2011-07-16 Thread NikolaMKD

The getView() is called everytime the listview is populating data,
what is meant by this, getView() is called everytime when there is
need views to be recycled. Let's say if you have 20 elements in your
listview, the maximum items visible is 8, the first time you view the
listview, getView() is called 8 times, if you scroll down by x items,
then the getView() will be called x more times. It is normal seeing
getView() called multiple times.

Ah, ok.  I've never seen one of the tablets yet.  I want one, but the
only ones I can, at times, afford, look pretty cheesy

Ok, how about one of these:

   A) change (only for the current viewing of the main list) the

Now I am not trying to rip on Apple but this is absolutely ridiculous...

I wouldn't do that, either.

Bear in mind that beyond pointing devices and selection, row color
plays an important role in tablets running Honeycomb ("activated" rows
to show context for an adjacent fragment). I really cannot stress
enough that you should leave the row colors for system-defined roles
and do something else to mark rows of interest.
