from:"Kookamonga"

I have what seems like a very basic question: how can I maintain the
sorted state of a ListView as new items are added to the list?

I have a ListView that is populated from a database. Specifically, I
query my database, create an ArrayList of items, and use a custom
ArrayAdapterMyType as the adapter of the ListView.

Now, I understand that I can use ORDER BY in my db query when
initially populating the list. But what about when new items are
inserted? I also understand that I can call the .sort() method on the
ArrayAdapter... passing in a Comparator... But does this mean that I
have to call sort every time a new object is added to my database (and
thus, my ListView is updated)? That doesn't seem right.

The answer here (http://stackoverflow.com/questions/3496137/how-to-
update-a-cursoradapter-tied-to-listview-when-number-of-items-changes)
by JRL seems to indicate that using a CursorAdapter doesn't really
solve the problem either.

I have searched around but not found an answer to this question. All
I've found is help on how to sort in the first place, for example:
http://groups.google.com/group/android-developers/browse_thread/thread/b21831ed773bf1fa.

What I need is something like a setSorter(...) method that's available
on certain Eclipse Viewers. Does something like this exist?

Thanks as usual for your help!

[android-developers] Re: Maintaining sorted state of a ListView

I've hit a problem in changing over to a CursorAdapter. The custom
items in my ListView contained a Checkbox. After reading online, I had
successfully implemented maintaining the state of the Checkbox such
that it worked with view recycling: I was storing the state of the
Checkbox in the same object as was added to my ArrayAdapter. This way,
I was able to retrieve and set this state correctly in the getView()
method of my custom ArrayAdapter.

Now, when I switch over to a CursorAdapter, all of the data used to
populate my view is coming from a Cursor... I've figured out how to
handle view recycling over the new bindView() and newView() methods
(http://stackoverflow.com/questions/3535074/getview-vs-bindview-in-a-
custom-cursoradapter), but how do I handle this Checkbox state thing?
Does it now necessarily have to be a part of my database (seems to be
the case if all bindView() and newView() get is a Cursor...)? This
means that now every time a user checks/unchecks an item in my
ListView, I'm making a database update() call to save the Checkbox
state. Is this the way to do it?

Thanks for your patience. I'm trying to explain the problem as clearly
as I can, but to be honest, I'm just trying to understand it myself,
so I'm not sure if it is coming across in a coherent manner.

[android-developers] Re: Maintaining sorted state of a ListView

I have another problem. I was scheduling an alarm for each item in my
ListView. Users were able to edit the time for the alarm by editing
the item in the ListView. Per the docs, I had to cancel the previously
set alarm myself and set a new alarm for the updated time as specified
by the user during their edit (i.e. there was no way to replace a
previously set alarm...).

In the previous way of doing things, with a custom ArrayAdapter, I
was of course using a custom object type as the contents of the
ListView. I had added a field of type PendingIntent to this object.
This way, when a user clicked on an item in the ListView, I could
retrieve the custom object backing this item and then cancel the
PendingIntent that had previously been scheduled.

But now, if I use a CursorAdapter, the object backing this item is
simply a Cursor. How would I maintain such an association between some
custom object and an item in my ListView? It seems as though using a
CursorAdapter severely limits our freedom in terms of saving content
to be associated with an item in the ListView WITHOUT adding it to the
database itself.

Thanks again for your help and patience. It certainly isn't easy
navigating through all of this for the first time.

[android-developers] Re: Beginner Question

This is more a Java question than an Android question. Let me give it
a shot.

The setOnItemClickListener(...) method requires an object that
implements the OnItemClickListener interface as an argument. In your
code snippet above, you are providing such an object by creating an
anonymous class (you can Google that). While you can't save just the
function somewhere else, you could create a class that implements the
OnItemClickListener() interface (i.e. in its own file or even as an
embedded class within the Java file that contains this code) and then
create a new instance of it to pass to the setOnItemClickListener().

So, something like this:

// Create this class somewhere else
class MyOnClickListener implements OnItemClickListener() {
   // implement the required method
}

gridview.setOnItemClickListener(new MyOnClickListener());

 Hi everyone. I'm not sure if this question belongs here but here
 goes..

 I am a professional asp.net developer looking to get into android dev.

 I have been going through tutorials and having fun so far!

 I have a question related to how the tutorial is asking me to
 structure my code.
 The code is from a tutorial where I create a gridview and set up a
 click listener event:
 gridview.setOnItemClickListener(new OnItemClickListener() {
                 public void onItemClick(AdapterView? parent, View v,
                                                  int position, long id) {
                         Toast.makeText(HelloGridViewActivity.this, Position: 
  +
 position, Toast.LENGTH_SHORT).show();
                         }
         });

 To me this structure is kind of messy, what I would like to do is have
 the function, public void onItemClick be by itself, so that I can do
 something more along the lines of: (psudo code)
 gridview.setOnItemClickListener([somehow reference the function
 here]);

 Is what I'm asking possible?
 Does my question make sense?
 Is there a more appropriate group to ask this kind of question?

 Thanks very much for your time.

[android-developers] Re: Beginner Question

Mark has way more experience than me, so I'll let him give the
definitive answer... But my two cents are that it depends on the
situation. :-)

For example, if the widget for which you are writing the listener will
only appear in this Activity, then having the Activity itself
implement the interface is probably fine. But, say for example you're
creating some layout that appears on all of your activities (maybe a
common group of buttons or something like that), then I would create a
separate reusable listener class that saves you from having to
duplicate code.

Please feel free to correct me if I'm wrong about this general
approach.

 Thanks for your input!

 Inbetween when I posted this and when I checked it again I ended up
 doing something similiar to what kookamonga did.

 After I read your post Mark, I added the implements
 OnItemClickListener to my activity and was able to do just as you
 said!
 This is exactly what I was looking for.

 So my next question is, in your opinions, what would be the better way
 to structure this?

 1.) having my activity implement the OnItemClickListener
 2.) creating an embedded class inside my activity that implements the
 OnItemClickListener

 I think I over estimated my ability to jump right into this without
 learning a bit more about the java language.
 Thanks again!

[android-developers] Re: Beginner Question

 I'm not sure how useful this would be in the
 button group. Wouldn't each button need its own listener? Wouldn't there
 be an activity associated with them?

Yes, each button would need its own listener. But if that button
appeared on several activities - say it was a Settings button, or
some such - you wouldn't need to duplicate the actual code performed
in the onClick method several times. So, say the button appears in 2
activies, A and B. You could do this:

Activity A

... onCreate(...) {
   ...
   settingsButton.setOnItemClickListener(new OnItemClickListener() {
  public void onItemClick(AdapterView? parent, View v,
int position, long id) {
  // do something
  }
   });
}

Activity B

... onCreate(...) {
   ...
   settingsButton.setOnItemClickListener(new OnItemClickListener() {
  public void onItemClick(AdapterView? parent, View v,
int position, long id) {
  // do something
  }
   });
}

Or, if you had created a separate class for the OnItemClickListener()
and as long as the do something was the same, which it likely is in
the case of something as generic as launching a settings activity,
showing a toast, etc., you could do this:

Activity A

... onCreate(...) {
   ...
   settingsButton.setOnItemClickListener(new MyOnItemClickListener());
}

Activity B

... onCreate(...) {
   ...
   settingsButton.setOnItemClickListener(new MyOnItemClickListener());
}

And now you have to update the common onClick actions in one place,
etc. I think this works and would server to improve maintenance,
readability... you know, all those good things.

Now, here's something I'm not sure about at all, but I'm throwing it
out there. I've seen an android:onClick attribute for buttons where
you can specify the method to run on the click event. The docs say:

This may also be a reference to a resource (in the form
@[package:]type:name) ...

So perhaps you can even get rid of the call to
setOnItemClickListener(...) in all of the Activities that re-use the
same button. But like I said, I've never played with this, so I'm not
sure about it.

 Good point. I don't have a particular problem starting out with the
 anonymous class early in the project. When it's needed elsewhere It's a
 straight forward refactoring to extract the class. I'm pretty new to
 Android, at first glance, I'm not sure how useful this would be in the
 button group. Wouldn't each button need its own listener? Wouldn't there
 be an activity associated with them?

I won't argue that a setting in SharedPreferences won't work...

But at the same time, shouldn't it be possible to do this just with
the Intent itself? If you use the putExtra method on your intent and
add just a simple boolean that indicates that the button should be set
to on, I would think this would work. Did I miss something?

I think I can be a bit more helpful. You basically have to use the
addRule method of RelativeLayout.LayoutParams as shown here:

[android-developers] Re: Changing ImageView background with a custom image

2012-02-19 Thread Kookamonga

In case anyone tries to do this in the future, I figured it out. In
hindsight, it is so bloody obvious...

You simply specify both the android:src attribute of the ImageView and
the android:background attribute as well. The android:src points to
the image you want to display in the ImageView and the
android:background points to the selector you are using to set
different backgrounds depending on the state (pressed/focused/etc.)

I don't know WHY I spent so long trying to accomplish this with only
the android:src attribute. Dumb.

 It is much easier to create multiple such drawables for changing the

 on top of the changing background. Hopefully this is more clear.

[android-developers] Re: Prevent image from being scaled in ImageView

2012-02-11 Thread Kookamonga

Well... I should thank you. Based on your XML, I tried
android:scaleType=fitCenter and the image now appears as-is, without
any scaling.

I'm confused as to why this works and not just
android:scaleType=center. Based on the docs (http://
developer.android.com/reference/android/widget/
ImageView.ScaleType.html), center should perform no scaling. I
tried a bunch of things, but never fitCenter as the
android:scaleType... So thanks!

For completeness, let me answer your question. Yes, I was saying that
the X gets scaled up, but not quite to the full size. When I used
android:scaleType=centerCrop, the X was scaled to fit the entire
ImageView. When I changed to android:scaleType=center, it was only
scaled up a little bit, but not to fit the entire view. And now, with
fitCenter, it appears as-is.

On Feb 11, 7:38 am, Doug Gordon gordo...@gmail.com wrote:
 Are you saying that the X gets scaled up to the full size of the

 This does *not* scale up images that are less than the max dimensions.
 But I might be aiming for something quite different from your case.

[android-developers] Re: RelativeLayout created in Java not XML - is this possible?

2012-01-24 Thread Kookamonga

If I understand you correctly, this is certainly possible. The integer
argument is an ID, so you just have to call setId() on your
programmatically created views first (where each ID is unique...), and
then use view.getId() in the addRule() method. See here for a somewhat
more complete explanation:
http://stackoverflow.com/questions/2305395/laying-out-views-in-relativelayout-programmatically

On Jan 24, 9:57 pm, Guy Smith g...@multiniche.org wrote:
I want to create a RelativeLayout in Java code, rather than using the
XML format.

It seems RelativeLayout.LayoutParams.addRule() would be the way to add
relative positioning constraints. However, this doesn't take a View
anchor argument, just an int anchor argument. Does this mean you can
only use XML-specified Views as the anchor in constraints?

All the examples tutorials I've found for RelativeLayout assume you
are using XML-specifications. I'm constructing the layout
programmatically because the layout is very dynamic - each region of
the screen has structured content (eg, a crossword square) which
varies according to the size of the crossword chosen, and the degree
of zooming.

[android-developers] Re: Sending mail through GMail (again...)

2012-01-21 Thread Kookamonga

In case any one is reading this later, the solution I settled on was
porting the Python xoauth.py script to Java and integrating into my

Because, at the end of the day, the behaviour is *identical* to the
solution described here: 
http://blog.doityourselfandroid.com/2010/11/10/oauth-flow-in-android-app/.
This still requires the user to grant access outside the usual Android
framework, which is unfortunate... Oh well.

On the plus side, I learned some Python. So I guess it wasn't a
complete waste of time.

re: your initial reply, I believe we're talking about different
permissions. It sounds like you're referring to the permissions that a
user must accept when first installing the app. I'm not talking about
those. I'm talking about permission the user has to accept that allows
the app access to the user's Google Account (see screenshots in the
thread I've linked to). In Android terms, this would be as a result of
a call to AccountManager's getAuthToken(...) method.

Uninstalling the app is hardly a solution! First, I'm not even sure if
it will work (because I don't think this permission to access one's
Google Account is stored on the phone), but even if it did, it seems
kind of heavy handed to have to re-install the app if you've
accidentally granted certain permissions...

I was hoping there was some way to do it online through one's Google
Account settings. This is already mentioned in the thread linked to in
my initial post, but this is how one would revoke access to Chrome-To-
Phone, for example...

Oh well, still no satisfactory answer. (To tell you the truth, I don't
understand the broadcast receiver answer... )

[android-developers] Re: Revoke permissions to access Google Accounts

2012-01-18 Thread Kookamonga

Nikolay:

Thanks for the explanation. While I was aware about the server/client
sides to AuthToken, I didn't know the specifics of how it worked on
the Android side... Very informative! Much appreciated. Also, I was
aware of that Google website, but it didn't have the app that I
granted permission listed... which is why I posed the question in the
first place. Even my Google Accounts dashboard (which lists, for
example, Chrome-To-Phone), does NOT list this other app.

TreKing:

:-) Looks like uninstalling is in fact the only solution, given what
Nikolay says about the way the grants DB works. So thank you as well
for first suggesting it.

Kris:

No apologies needed at all; I appreciate you spending the time to
respond in the first place.

Thanks everyone, looks like we can close the books on this question.

 definition!

  First, I'm not even sure if it will work (because I don't think this

  I just tried with the AppBrain app. It does work.

 but even if it did, it seems kind of heavy handed to have to re-install the

 Perhaps, but it works. I would assume if you didn't trust an app to the
 point that you wanted to revoke the permissions granted to it, you would
 want to uninstall it anyway.

Yes, I also wanted a first-start-tour-of-the-app. A custom dialog is
an interesting idea as well. By making it transparent, I can get the
overlay effect I'm thinking about. Thanks for the tip.

 What I do in one of my apps (see middle

 is that I display a popup that contains a custom dialog displaying an
 image. Sitze set to just fit the picture. In my case it can be zoomed
 and panned, but it could easily include swipe detection and not be
 movable. Just thinking about it, I believe that is exactly what I will
 do to include a first-start-tour-of-the-app .-)
 What you can also see in the screenshot is that there are two menu
 bars. The user can show/hide them with a tap. In your case this could
 be a navigation bar to make sure that the user can skip the tutorial
 or whatever you want him to be able...

Alex,

Thanks a lot... The ViewPagerIndicator project was easy enough to
find!

On Jan 17, 2:12 pm, Alex Curran aml.cur...@gmail.com wrote:
 Having a look at the rest of the responses, this looks like it is probably
 a ViewPager with lots of ImageViews of screenshots. The ViewPager is found
 in the Android support libraries and there's plenty of source on the
 Android Developers website.

 The little circular things at the bottom can be made using Jake Wharton's
 (brilliant) ViewPagerIndicator project, just Google it and you'll find it.

 Hope that helps!

[android-developers] Android app with embedded tutorial

I'd like to embed a tutorial into my app that the user can step
through when the app is first started. Does anyone know how the Google
Currents app tutorial is implemented? It is extremely sleek and allows
users to step through at their own pace.

I found a similar question here:

http://stackoverflow.com/questions/5510258/building-a-tutorial-giving-a-hint-for-my-android-app

But the answer that is given - showing toasts at startup - is pretty
much a non-solution. Yes, I can simply have a series of Activities
that represent the pages of the tutorial and have the user step
through, but again, I'm looking to know the specific way in which the
Google Currents app tutorial is written.

Thanks for your help and time.

[android-developers] Creating step-by-step tutorial in app

[android-developers] Re: Creating step-by-step tutorial in app

Let me be clear. I'm not asking how to do the when the app is first
loaded. I'm asking how to actually create a tutorial that a user can
step through. The Google Currents tutorial is very slick. The tutorial
pages appear as an overlay (transparent too!) on the current Activity
that is running. I have no clue what type of view is used to do
that... Is it simply an ImageView with a transparent background? Or
what?

Thanks.

 I suppose there are lots of different things you can think of, however
 I suppose you've figured that out already..
