[android-developers] Re: Another AbsoluteLayout deprecation question

[Keith Wiley]

Right, and unlike some of the other posters who seemed to have a
slight more agitated tone, I really tried to emphasize that I want to
get on board with respect to this particular issue.  I'm not
complaining about AbsoluteLayout's deprecation at all, I just want to
write my code correctly, and if AbsoluteLayout is not the recommended
way to place one view at an arbitrary location on top of another view,
I was just wondering what *is* the recommended way.  I was getting
confused because some places said FrameLayout and RelativeLayout were
the solution, but other places were very clear that they weren't the
best solution.  I had also seen the suggestions of rolling a layout
manager on my own...I was just...a little unsteady about that.

I'll look into making my own layout manager.  Please consider how
confusing this is for those of us not already in the know.  For
example, I would assume this consists of writing my own layout class,
something akin to AbsoluteLayout or LinearLayout, etc.  The funny
thing, which I find very confusing, is that none of those are actually
subclasses of Layout!  They subclass ViewGroup, while Layout is some
other class which doesn't seem to have any direct connection to the
existing Layouts.  Thus my impending confusion.

I'll do some research on layout managers on my own first, the pointer
in that direction was sufficient, thank you...I'm just asking that you
please realize the apparent discrepancy in terminology which I find
confusing.

Cheers!

[android-developers] UI problem

[Sukitha Udugamasooriya]

Hi geniuses,

I have few buttons on the content. When I click on one button,

1-- I want to change the text of the button.
2-- Then I want to change the content view.

this is my method which executes with the onClick event.

private void markUser(int index) {

btnArray[index].setText(mark);
btnArray[index].setClickable(false);

showGameOverMenu(); // calls the setContentView();
}

Here the problem is the text change of the button is not visible.

How can I make it visible??? I'm not thorough with how the UI thread
works in android

Thanks in advance

[android-developers] Options for synchroinizing data between Android and backend database

[Lonifasiko]

Hi all,

Wanted to develop a mobile application for Android devices that stores
data locally and synchonizes (bidirectionally) local data with a
database server every 'N' minutes. That is, instead of building a web
application accesible from Android's browser that forces me to be
"always connected", I wanted to try the approach of "sometimes
connected" scenario.

I was thinking in using MySQL as server backend, but new to Android
and don't know which are the options to communicate and synchronize
data between mobile devices and servers. Is there any Android library
that makes this always hellish synchronization work easier?

What about Google Gears?

Thanks very much in advance.

The system scrollbar does not have a track anymore. Your code should
simply account for that possibility. The framework code does attempt
to load a scrollbar track but does not crash if no resource is
present.

[android-developers] Re: dynamically setting drawSelectorOnTop

[Romain Guy]

Oops my bad, you were talking about *Spinner*. Spinner does NOT
support android:drawSelectorOnTop, so there's no equivalent Java API.
Setting this attribute in XML has absolutely no effect (in particular
because a Spinner does not have a selector.)

[android-developers] Re: Another AbsoluteLayout deprecation question

Again, AbsoluteLayout was deprecated to encourage developers to use
"real" layout managers. AbsoluteLayout just won't work with other
screen resolutions and densities. Like Dianne said, it won't go away
but we want you guys to think very hard before using it. It is (most
of the time) bad practice and will only come back to haunt you in the
future.

Everybody, even to an extent the core Android team folk on this list, is
contributing answers on a volunteer basis. Lots of questions get asked
here that do not get answered, for any number of reasons.

Also, bear in mind that you sent your question less than 24 hours ago. Not
everybody monitors this list continuously. If you need answers in that
short of a timeframe, hire a consultant.

I have watched your thread since its inception. I did not reply at first,
because you seemed set on having a core Android team member answer, and I
am not such a person. However, since your focus now seems to be on getting
some sort of answer from anyone, here's my take on it:

According to Ms. Hackborn's most recent(?) post on the topic, while
AbsoluteLayout is deprecated, it is not going away. Strategically, I
suppose that means no new code should be built that relies upon
AbsoluteLayout, but there is no need for a massive rush to the exits to
abandon AbsoluteLayout for existing code.

Personally, if I were in your shoes, I would aim to eliminate my
dependency on AbsoluteLayout in the next few months. Note that "eliminate
the dependency on AbsoluteLayout" could be simply a mental bookmark that,
should AbsoluteLayout ever be truly removed from the platform, that you
will be willing and able to maintain AbsoluteLayout yourself, based on the
last implementation found in the Android open source project.

But, again, Ms. Hackborn has indicated AbsoluteLayout is not going away,
and so you may elect to not worry about this issue in the near term.

I believe both of them, in related threads, indicated that the solution is
to create your own layout manager, rather than use AbsoluteLayout or
RelativeLayout or any of the other built-in ones.

Unfortunately, I am unaware of any tutorials on exactly how to do this.
You can probably examine the source of some of the existing layout
managers to see how they do what they do.

First run "adb root" this will give you root access to G1's file

[android-developers] 1.5 api change - broken scrollbar resources

[Peter Carpenter]

Hi all,

I've just been attempting to upgrade my application to support 1.5 and
discovered that I can no longer retrieve a resource for my scrollbar
background.

My app requires me to draw a scrollbar that I can use to control a
custom component.

Currently I was using the following code (which Jeff was kind enough to
point me in the right direction of):

TypedValue val = new TypedValue();
if (context.getTheme().resolveAttribute(
   android.R.attr.scrollbarThumbVertical, val, true))
{
scrollThumb = getResources().getDrawable(val.resourceId);
}
if (context.getTheme().resolveAttribute(
   android.R.attr.scrollbarTrackVertical, val, true))
{
scrollTrack = getResources().getDrawable(val.resourceId);
}

However the 2nd getDrawable causes a ResourceNotFound exception so it
appears the scrollbarTrackVertical has been removed??

Does anyone know of any other ways to get the system scrollbar
drawables? (or a system scrollbar by itself?)

Regards,

Peter.

[android-developers] Re: Threading and Message Loops

[radarcg]

I replaced my threading code with the AsyncTask, and its such a direct
solution for my issue that I don't need to post my code. The
references listed above provided all the solutions. Also, the
stacktrace also seemed to be caused by the reason stated above because
it too went away with this solution. Thanks again!

[android-developers] Screen/Activity orientation

[doubleslash]

Situation:
 I set my activity to be in landscape mode. In this activity, I move a
box along the x direction, which is along the longer side of the phone
due to being in landscape. When the activity is first started,
everything works great--the x axis in my code corresponds to the
expected x direction in landscape.

Problem:  if in the middle of running it, I go into the dialer app by
pressing the call button, and then going back to my app, the box still
moves in the "x direction" but now perpendicular to the supposed
landscape x direction. I suppose the dialer's portrait mode got passed
onto my activity even though the orientation is set to landscape in
the manifest.

Attempts: I have tried numerous ways to remedy this but to no avail. I
tried re-initialzing all my views, calling setContentView upon
Restart. I also tried to get my orientation by calling
getResources().getConfiguration().orientation. The result indicates
"landscape" although the x axis now is perpendicular to before.

Please help! How do you deal with orientation change

[android-developers] Re: dialog is getting dismissed when I am flipping the device

Hi Dianne,
I suggested the way i followed to retain the state of the dialog, which may
not be preferred. Thanks for the suggestion.
It would be good if you could provide a sample as to how to retain the state
after flipping, so that i could implement the same.

[android-developers] Send SMS Message

[yves...@gmail.com]

There are lots of post talking about sending SMS messages. But my
question is not answered there.

So, I can send sms messages using my app, but after the message is
sent, I can't find them in the "Messaging" app's outbox, you know,
like it list all incoming and outgoing messages. What I want to
accomplish is that whatever app user used to send text message, it
should show up in the "Messaging" app.

Any ideas on how to solve this?

I used smsManager.SendTextMessage call to send text message.

[android-developers] Re: Problem installing application onto HTC Magic

[Xavier Ducrohet]

If you develop an application that uses MapView (with your manifest
declaring a uses-library node with com.google.android.maps), it will
never install on a device that does not have Maps (actually Google
Maps is not required, it's the Google Maps library that is required.
I'm guessing if your device doesn't have the application, it doesn't
have the library either.)

The MapView class is not part of the standard API (its namespace is
not android.* but com.google.android.*), hence the reason it's now
published as part of the Google APIs add-on, and requires the
uses-library entry in the manifest.

[android-developers] Re: DexClassLoader caould not invoke method from another application properly

[Ask]

Fadden,

   It throws these exceptions only when " I tried to create any UI
component like Toast message or invoking phone dialer inents etc. " It
executes nicely when I just "tried to print a log message or created
MediaPlayer and playing a song "   .

  So my conclusion is that It throws NullPointerException only when
invoked code has a UI component.

  Note: same thing I had tried using the normal desktop java
application using swing and excuted nicely with UI component also. So
Is this a bug in android or some other way to do it.

Thanks,

Asif

Hi
I have an offer for you
keep your dictionary as text file
zip it and store it in the asset or raw resource direcory
ZIP can provide really good results on text
use Java ZipInputStream to expand it to the SDCard
in you app , do background SQLlite buildup, simple do the population
on a different thread.
users will agree that upon running (not installing) your app they will
be slower or wait a bit
maybe consider some progress bar...

[android-developers] Eclipse : Unknown error: SDK is not loaded yet. * upgrade failed *

[chrispix]

Not sure what is going on. Running Windows Vista x64.
Not had really any problems with eclipse. I had to upgrade to 1.5 and
when I did that I got all kinds of install errors. So I said 'f-it'. I
decided to start over and downloaded the 1.5SDK, downloaded the
Eclipse for Java, Not Eclipse classic (someone said that was an
issue). So now I have Eclipse for Java (or something to that name).
Each time I try to compile it says 'Unknown Error: SDK is not loaded
yet'

Can someone assist me please? thanks.

[android-developers] Re: how to know whether an app is installed or not

[android app]

For a paid app, the app will be still in the "My Downloads" even if it
is uninstalled.  You can re-install the app from "My Downloads".

I am looking into getInstalledPackages(int flags).  Just found an
option for flags::GET_UNINSTALLED_PACKAGES, which may return
applications with "DONT_DELETE_DATA".HOPE this works.

So now my question is about how refund affects the "My Downloads"
list.  If an order of a paid app in cancelled / refunded, will and
when the app disappear from "My Downloads"?

Thanks, Johnny.

Hi BiAji
yes, I had a spelling mistake
the firmware is made by Jesus Freak

anyway the supplied terminal emulation in JF ADP1.5 does perform su

I think the results from the PackageManager is accurate.

The "My Downloads" is propobably saved the downloaded info in its own
provider.

One test, can you launch the application from "My Downloads" after
uninstall it?

Thanks, Jeff.

Can an app know whether another app was installed if it was
uninstalled and is still in the "My Downloads" list?  A purchased
application will still in the list of "My Downloads" even after it is
uninstalled.

Yes, as Jeff suggested, PackageManager#getInstalledApplication and
getInstalledPackages is what you need.

[android-developers] Re: where to download android 1.5 r1 source code ?

[Johnny]

I'm afraid you'll have to get familiar with git and repo.

If you want to work with the source code.

There is nowhere to find a single zip file of the source code, that's
a too old way for code distributions.

You can programatically access all packages installed.  Something like
PackageManager.getInstalledApplications() is probably what you're
looking for:

Yeah, I saw it in the documentation online but when I do

I am using Android android-sdk-linux_x86-1.1_r1. Do I need to upgrade?

Actually , the emulator can not exec "su" correctly,  it will return

JF firmware, It will exec correctly. BUT...you should allow it to exec
in superuser app.

[android-developers] simple MediaController example

[kostmo]

Hi,
I would like to show the MediaController (http://developer.android.com/
reference/android/widget/MediaController.html) view (with the play/
pause buttons and progress bar) when a button is pressed.

The backend passed to setMediaPlayer() is a
MediaController.MediaPlayerControl implementation that simply returns
constant values for the progress.  I intend to hook these methods up
to something more complicated later.

The expected behavior is for the MediaController window to be
displayed for 10 seconds when the button is clicked.  Instead, nothing
is displayed when the button is clicked.


The code I have tried is below:
-

package com.example.android.helloactivity;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.MediaController;


public class HelloActivity extends Activity {

private MediaController mc;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

LinearLayout v = new LinearLayout(this);
setContentView(v);

mc = new MediaController(this);
mc.setMediaPlayer(player_interface);
mc.setEnabled(true);
mc.setAnchorView(v);

Button b = new Button(this);
b.setText("show the player");
b.setOnClickListener(my_click_listener);

v.addView(b);
}


private View.OnClickListener my_click_listener = new
View.OnClickListener() {
public void onClick(View v) {

mc.show(10);
Log.d("mydebug", "button clicked.");
}
};

private MediaController.MediaPlayerControl player_interface = new
MediaController.MediaPlayerControl() {

public int getBufferPercentage() {
return 75;
}

public int getCurrentPosition() {
return 25;
}

public int getDuration() {
return 180;
}

public boolean isPlaying() {
return true;
}

public void pause() {
}

public void seekTo(int pos) {
}

public void start() {
}
};
}

[android-developers] webView: How to click a web link and display in my WebView app

I am trying to add a webview in my app to display a web page. However,
every time I click link on the web page, Browser will be launched to

[android-developers] problems with my htc magic

[petunio]

Hi everybody

I am trying to install apk's in my new htc magic

I had before a G1 and I didn't found any problem, just doing adb
install myapp.apk and that's it

now, when I do the same with my htc, it says "error: device not found"
Also, I noticed that if I type "adb devices", I dont get any device
shown...

I have also done the following settings in the mobile, with no luck:

settings->applications->unknown sources (checked)
settings->applications->development->usb debugging (checked)
settings->applications->development->allow mock locations (checked)

I know that is not a problem with the usb cable, as I have tried a few
of them, including the one that was working with the G1...
It could be a problem with the usb drivers, but everything seems fine
in my device manager...


has anybody come across this problem?

It's even simpler than that.  In system/extras/su/su.c:

if (myuid != AID_ROOT && myuid != AID_SHELL) {
fprintf(stderr,"su: uid %d not allowed to su\n", myuid);
return 1;
}

So it should not work in the terminal application, but it should work
from "adb shell".

Something to play with: grab http://bigflake.com/gclog.py.txt and run
it.  It will format the GC events from the device event log.  You'll
see stuff like this:

05-13 15:07:35 acore(2600) softlim=6464KB, extlim=2368KB,
extalloc=2368KB
  freed 1024 objects / 46336 bytes in 138ms

softlim + extlim may not exceed 16MB.  (It's actually more complex
than that, but that's a good approximation.)  "extlim" is the amount
of space currently being set aside for bitmaps, while "softlim" is the
virtual heap soft limit.

You will see GC events for all processes -- the script doesn't have
any fancy filtering features yet -- so you need to search for your
app.  The above is from process 2600 (acore).

This won't provide any detail about what's going on, but it may give
you a better sense of how things are allocated.  For example, if
softlim+extlim exceeds 4MB, a 12MB bitmap allocation is not going to
succeed.

[android-developers] Re: JNI check failures when trying to use a configured SOCKS Proxy object...

[fadden]

...and so it is.

OSNetworkSystem.java declares:

   static native InetAddress getHostByNameImpl(String addr,
   boolean preferIPv6Addresses) throws UnknownHostException;

That ends up here:

static jobject osNetworkSystem_getHostByNameImpl(JNIEnv* env, jclass
clazz,
   jstring nameStr, jboolean preferIPv6Addresses) {

which does this:

   jbyteArray addr = env->NewByteArray(4);
 ...
   return addr;

So, it's returning a byte array when an InetAddress object is
expected.

I'm not sure what a workaround would be.  For reference, here's the
stack trace (via a new extension to the "Check JNI" feature), using
the provided APK:

I don't think that takes into account bitmaps, which don't exist in the
normal Java heap, but do deduct from its total.

Of course at some point in the future, for some set of devices, it will go
up.  It will also of course never go down since that will break lots of
applications.

[android-developers] Re: Framework support for detecting starting and stopping of activities

[Dianne Hackborn]

There is nothing in the SDK for this.  In 1.5 there is now some lauch
information maintained by the system, which you can modify to have reported
if you'd like, though it is pretty rudimentary (for each day, the number of
times each .apk has been resumed, and the total duration it was resumed).
You will need to build your own system to do anything like this though.

[android-developers] Re: java.awt

[bra...@gmail.com]

I have very nearly finished porting the java.awt lib to android. I
have skipped all the swing functionality as I cannot see us need ing
it along with some fairly large chunks of the text handling. Graphic
manipulation and IO etc should all still work.

If you are ever given the choice between building your own awt lib and
smacking your face into a wall. Choose the wall. Less painful

[android-developers] Re: Animated progress in Imageview

[Jeff Sharkey]

You're probably looking for AnimatedImageView instead of ImageView,
which will trigger the animation automatically once its visible.
Here's an example in an XML layout:

I'd vote for RotateAnimation, personally, but that's only because I've
used it for the scenario you're describing.

[android-developers] Re: Animated progress in Imageview

[Al]

Forgot to mention, the progress indicator is indeterminate, like you
have in an Activity with Window.FEATURE_INDETERMINATE_PROGRESS.

I've had a look at RotateDrawable, which seems to be the correct thing
for me to use. The docs say a RotateDrawable should be used with an
xml that uses . I've tried various methods to get it to
animate:

img.setImageDrawable(getResources().getDrawable(R.drawable.progress))
img.setImageDrawable((RotateDrawable) getResources().getDrawable
(R.drawable.progress))
and img.setImageDrawable(R.drawable.progress)

All of these bring up a static image. Just to clarify, I think it
might have been unclear earlier, my ListView row looks like this: |
[Text   ][Image]| where | is a boundary of a view container.
The image box can contain various images to indicate the state of
background activity, a red circle to indicate something wrong, green
to show nothing unexpected has happened, etc. The indeterminate
progress (should) show up when the user requests an operation that
will (possible) take a while to complete.

[android-developers] Framework support for detecting starting and stopping of activities

[clemsongrad]

To support usability studies on what applications are used, i want to
write a service that logs when an activity is started and also when it
has finished.  This is to understand how the users are using the
device:

One straightforward option is to have the applications modify, to
write this out.  But this is tedious having to modify all applications
and will not work esp with third party or built in applications.

Is there any alternatives that makes this simpler and easier?

BTW: Looking at the android framework source ActivityManagerNative
seems to be invoking a Binder interface when an Activity is started
and finished.  Any information on what this service is?   Is this
something i can tap into?

Apologizes if i am looking at the wrong code, my first foray in to the
framework code.

Any information or thoughts is greatly appreciated.

Thx!

[android-developers] Re: Question: How to guestimate the available bitmap memory on a device

[Streets Of Boston]

According to the heap 'browser' that comes with the ADT plugin in
Eclipse.
My app is using less than 4MByte (it's using about 2MByte) but it
won't allow me to create a bitmap of 12MByte.

About max heap usage: Is and will the heap limit be set to 16MByte on
all devices (i.e. on current devices such as G1, Magic and also on
possible future android devices)?

[android-developers] Re: How do I make a ListView scrollbar expand whilst scrolling?

[Dianne Hackborn]

Yes this is a new API in 1.5.  If you need to run on older versions, you can
copy the old code out of Contacts before it was integrated into the
framework.  (That's what I did for Rings Extended.)

[android-developers] Re: How do I make a ListView scrollbar expand whilst scrolling?

[Joel Wright]

Thanks for the help, I've got the scrollbar working how I wanted it
and I'm working on the SectionIndexer.

I just have one question left.

Does this mean I'm forced to use the Android 1.5 SDK if I want
fastScrollEnabled? - Trying to build the project at a 1.1 level gives
me a "no resource identifier found" error on my xml layout.

Thanks again,
Joel.

[android-developers] read from local socket does not work

[alexdonnini]

Hello,

I was wondering if anyone would explain to me why the code snippet
below does not work:

s.getOutputStream().write(length);
s.getOutputStream().write(data);

Log.i(TAG, "data from socket -
"+Integer.toString(s.getInputStream().read()));

In my application, the code is surrounded by try/catch. It does not
generate an exception.

s is an instantiation of LocalSocket.

The code does not work because the attempt to read data from the
socket never completes, i.e. no data is ever returned from the socket
(via the Log.i statement).

I would appreciate it if anyone could help me understand if and where
I made a mistake.

Thanks.

[android-developers] Re: get Certificates from Package

[friedger]

I would assume that the signature is valid, if not the package would
not be installed.

So a hacked Android version could break this assumption. But then the
API to access the public key or even the package file could be hacked
as well

db.execSQL(), instead of us trying to figure out what the resulting command
is by running the code in our heads.
My guess is that it doesn't work because you're trying to specify a
column-constraint using table-constraint syntax (column constraints don't
use the "FOREIGN KEY" keywords, according to
http://sqlite.org/lang_createtable.html)

[android-developers] Re: How do I make a ListView scrollbar expand whilst scrolling?

[Jeff Sharkey]

Also, to get the A-Z overlay when using fastScrollEnabled, you'll need
to implement SectionIndexer for your adapter.  Something like
AlphabetIndexer works great if you have a sorted Cursor.

[android-developers] Stuck in landscape mode after launching YouTube

[Chister Nordvik]

Hi!

1. User clicks an image in my app
2. The app launches YouTube
3. Screen is rotated in landscape
4. User presses home button
5. User starts my program again
6. My program is launched with the main screen but it's stuck in
landscape mode (due to Youtube switching orientation)

Nothing I do will make the screen go back "normal" mode again. Is this
a bug? It's only tested on 1.1 device since I can't test YouTube in
the emulator.

If anyone have a 1.5 device out there I would really appreciate if you
could test this for me. Just write me an email :-)

At the risk of replying to myself, let me provide a bit more to go on.

ListView supports setOnItemClickListener() and setOnItemSelectListener(),
so you can find out what rows are clicked or selected.

In the case of selected rows, your listener can simply call
getSelectedView() on ListView to get your row View, which you can then
modify.

In the case of a clicked-upon row, it looks to be a bit more difficult. I
cannot seem to find a clearly good way to get the row associated with a
position.

[android-developers] Re: Should I use Cursors, or and Object[] to return data from a DB

[Dianne Hackborn]

And there are of course other ways to do this -- have a PolygonCursor object
for instance that lets you iterate over the cursor and provides an API to
get the polygon data for the current position.

At the risk of replying to myself, let me clarify.

Creating more garbage to gain cleaner APIs is a trade-off. Created garbage
may affect your application, and it may affect other applications -- we've
had complaints on this list already from game developers who cannot
maintain consistent frame rates because of garbage collection in other
applications.

Similarly, adding extra VM instructions, to create DatabasePolygon objects
and pull data out of Cursors, chews up battery life.

You did not indicate whether you database will have one or 10,000
polygons. The magnitude of the extra garbage and instructions will be tied
to the number of polygons you create.

So, while I agree with you that dealing with Polygon objects may be tons
cleaner than dealing with Cursors, bear in mind there is a cost involved,
and be sure to weigh that cost when deciding what to do.

[android-developers] Re: Question: How to guestimate the available bitmap memory on a device

According to what heap dump?  I am pretty sure that the code just checks to
see if there is that amount of space left in the java heap, and if not fail
(otherwise allocate it and tell the VM to account for that as part of its
heap usage).

[android-developers] Re: Gallery usage without using styleable

[lilbyrdie]

I've answered my own question. Net result is the same, just a
different way of getting to the default theme resources, but it's what
I was missing.

Within your attrs.xml file, place a block that looks like the
following:





This basically provides access to the galleryItemBackground in the
same way as before, but explicitly making it a styleable now.

This is now used as before:

Within the ImageUriAdapter(), load the background:
TypedArray a = 
obtainStyledAttributes(R.styleable.default_gallery);
mGalleryItemBackground = a.getResourceId(

R.styleable.default_gallery_android_galleryItemBackground, 0);
a.recycle();

Then, within the getView(), apply the background:

imageView.setBackgroundResource(mGalleryItemBackground);

I hope this helps someone.

[android-developers] Re: Question on ContentProviders

[Jonathan Herriott]

Thanks Dianne.  That helps alot.  The reason I asked is because my
ContentProvider will allow other applications to insert into it,
similar to a logging system.  Since I can't guarantee an application
won't try to abuse it, I was just trying to figure out what type of
safeguards to put into it.

I'm very interested in exploring the responsiveness of the UI to large
cursors.

[android-developers] List items not clickable when using ListAdapter, but clickable with SimpleAdapter

[brian.schim...@googlemail.com]

Hi,

I was populating a list with a SimpleAdapter like this:

final List> data = someObject.getData();
SimpleAdapter dataAdapter = new SimpleAdapter
(this, data, R.layout.listline, from, to);
listView.setAdapter(dataAdapter);
listView.setOnItemClickListener(...);

The listView gets this from the layout.xml:
android:choiceMode="singleChoice" android:clickable="true"

R.layout.listline defines a layout for each line, having 4 TextViews
and some more widgets. Everything works fine so far.

But now I need to use a ListAdapter to populate my list. It was easy
to write a class that implements all those methods required by that
interface, and the resulting List looks exactly the same now. It
performs well on scrolling, changing data, etc. but the lines are not
clickable any more. My onItemClickListener.onClick is never called,
not matter where I tap on my list line (e.g. on one of the TextViews
or on the background of that line). In my implementation, I use
View.inflate to inflate excactly the same xml as the SimpleAdapter
did.

Shouldn't the click behaviour of a list be independant of where data
comes from?

I guess SimpleAdapter does some internal "magic" that I'd need to
perform in my own implementation as well, to make the line clickable.
Can somebody point out what I'm missing? I'd also like to look at the
source code of SimpleAdapter, but I coudn't find it anywhere on
http://android.git.kernel.org/ - maybe I'm just to dumb to look in the
right place. Can somebody point me to that code? (possibly without
forcing me to install git and download the whole code base)

thanks,
Brian
