Re: [android-developers] image overlay

[Atif Gulzar]

You may use ViewFlipper and then can use setDisplayedChild function to show
the view you desired.

 Is there a way to have an image overlaid over another image.  For

 another imageview to take up the same space and appear over the first

 the second imageview within the first imageview, but that's apparently
 not allowed in the layout xml files.  So is there perhaps a way of
 doing it with a different layout, such as absolute or frame?  Thanks

 Atif, the various layout classes are *intended* to be a generic
 solution, making minor adjustments for minor changes.

 Using different resource folders is intended for making major
 readjustments to layout. If you design a good layout with the layout
 classes, you may not need them at all!

 Generally, separate resource folders are useful for when a particular
 layout strategy simply breaks down when pushed too far. For example,
 rotating to landscape may make the screen simply too short for one
 strategy, but if you move a couple of things to the side, you're OK.

 If you need to distinguish between 480x800 and 480x854 -- and
 especially if it's 480x854 that has the problem -- then I would
 strongly suggest that you take a close look at your layout strategies.
 LinearLayout with some expandable padding elements, TableLayout, or
 the use of a 9-patch instead of a fixed background graphic.

 Android offers a lot of facilities for handling of layout differences.
 I don't think they're always as easy to use and predictable as they
 ought to be, but they're pretty rich and functional, none-the-less.

 So if they aren't doing the job, and you're having to rely on
 differentiating your layouts at the level of 480x800 vs 480x854, then
 to get any help, you're going to need to precisely identify what
 problem the layouts aren't handling for you automatically, and why.

 My guess, however, would be that you're either:
 1) Trying to put too much stuff onto each screen. This makes your
 layouts very brittle, and usually makes the result seem very
 cluttered for the user, as well. There can be times when this is
 appropriate -- for example, when the goal is a single-screen status
 monitoring display. But generally, the strategy here should be to move
 to less-cluttered, more tightly focused screens.

 2) Trying to keep too tight a control on the layouts, rather than
 defining a logical layout strategy, and allowing the system to make
 the layout choices for you, within defined ranges. That does take both
 a lot of understanding, and a lot of testing to identify the usable
 limits of each layout strategy. But the result is that you won't have
 to specify a new layout to handle some new device that adds another 54
 pixels along one edge.

Re: [android-developers] ViewFlipper switching views on screen orientation change

whenever the orientation is changed the onCreate fuction is called again
(unless you handled it). Means your activity is refreshed.

before orientation change happened  onRetainNonConfigurationInstance()  is
called. You can save you activity state in this function.

And then in onCreate you can get it by calling

Re: [android-developers] ContextMenu on TableLayout: how to get selected item position?

I had the similar issue and solved it with a work around. In your table row
add a TextView and makes its visibility GONE and set its text as 0,1,2,4...
for respective rows. Add a single listener for each row. When some row is
clicked the listener will give you a clicked view. From this view get the
text view from this text view the index.

 Any idea how we can achieve something similar in a TableLayout?

 I guess i will have to register the contextmenu for each row? but how can
 tie the row index with the menu? i see no way to do it with

RED5 is open source but you have to right midle tier for android to

SmartFox has inherent Android support.

[android-developers] retain application/Activity state correct approach?

[Atif Gulzar]

 hi,

I just read from internet to maintain the state of my application by
overriding the onKeyDown function as given below. And set the launch mode of
my activity as singleInstance. And it is working perfectly. Just want to
know if it is correct approach. And how it is different from
onSaveInstanceState. Thanks

   @Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
   if (keyCode == KeyEvent.KEYCODE_BACK)
  return this.moveTaskToBack(true);
   return super.onKeyDown(keyCode, event);
};

[android-developers] view inside a customView

[Atif Gulzar]

Is it possible to use standard views inside your custom defined views. e.g.
use ImageView in my class that is extended form View ?

Or is it possible to use one custom view inside another custom view?
Actually I have animations defined in xml view which I want to apply on some
of the images. But predefined animations can only be applied to views.


The scenario is,  I want to animate (rotating, glowing, etc ) some of the
chips  on a board. User can also drag these chips through touch events. And
I do not want to refresh my complete board just to rotate few chips on it.
All my animations are defined in xml files. Looking for some pointers.
Thanks

Re: [android-developers] AsyncTaskPool | Tutorial

 That is NOT the purpose of AsyncTask. Also, since Donut, the limit of
 enqueued tasks in AsyncTask is 128, not 20. So AsyncTask has a maximum
 of 10 threads running concurrently and can hold up to 128 tasks
 waiting for a thread to be freed in the pool. So basically AsyncTask
 does exactly what you are trying to do here.

[android-developers] Drawable.createFromStream() and OutOfMemoryError exception

[Atif Gulzar]

Hi,

Would you please help me how to handle the memory leak on
Drawable.createFromStream()?

 I am receiving a base64 image from a webservice. And I decode it using
Apache lib. After that I convert it to drawable through
Drawable.createFromStream(). But when the image size is bit larger (~350kb)
it starts throwing OutOfMemoryError exception. Ok, I can handle this by
catching this exception. But eventually after catching 2 or 3 such
exceptions the heap is full and it start throwing exceptions for other
methods and for small images as well.

The relevant code snip is given below.


byte[] arr = null;
InputStream imageStream = null;
try
{
arr = Base64.decodeBase64(result.getScreenShot().getBytes());

imageStream = new BufferedInputStream(new
ByteArrayInputStream(arr));
TJCAppDetail.this.screenShotDrawable =
Drawable.createFromStream(imageStream, src);
screenShot.setImageDrawable(screenShotDrawable);
}
catch (OutOfMemoryError outOfMemoryError)
{
arr = null;
imageStream = null;
if (screenShotDrawable != null)
{
screenShotDrawable.setCallback(null);
if (((BitmapDrawable) screenShotDrawable).getBitmap() != null)
((BitmapDrawable) screenShotDrawable).getBitmap().recycle();
}

Log.e(TJC_EXCEPTION, outOfMemoryError.getMessage());
}

 Hi,

 But in the meanwhile(before completing this AsyncTask) if the application

 So is it possible to get the active Context dianamically? Thanks

 You cannot reference resources by R.layout, R.id, and such from within a
 JAR such as what you have packaged. You need to adjust your API so the
 application reusing your JAR can pass those values in as parameters.

 What happens is that even though you copied over the resources, the
 resource IDs (the numbers that R.layout.foo and R.id.bar map to) will be
 different in the new project.

 Hi there,

 A 'Button' view comes up with text, while the 'ImageButton' widget
 comes up with an image but no text, is there a way to relatively
 easily (e.g. method calls, say), either:

 1. Add text to ImageButton (like those buttons that appear in menu
 item/via the physical menu button)?

 or

 2. Add an icon/image to a Button?

 without resorting to constructing a new button class?

 I.e. I could put text within the image, but then I can't use
 Localization properly/effectively.

 Any suggests, much appreciated here.

 Yes, all activities, services, receivers, and providers must be declared in

  This is how I make libraries for Android in Eclipse:
  1. I make a new Java project
  2. In the project properties, at Java Build Path - Libraries, I replace
 the
  the JDK library with the android.jar, found in the Android SDK.
  From what I tested, this solution seems to work.

[android-developers] Re: disable scrolling touch events in ScrollView, just want to to scroll programmatically

[Atif Gulzar]

do not use scrollView at all and use LinearLauout and use combination of
touch events and scrollBy(int,
int)file:///E:/android-sdk-windows-1.5_r3/docs/reference/android/view/View.html#scrollBy%28int,%20int%29,
scrollTo(int, 
int)file:///E:/android-sdk-windows-1.5_r3/docs/reference/android/view/View.html#scrollTo%28int,%20int%29.
By this way you can also achieve horizontal scrolling.

 Just wondering if there is an easier way to simply stop ScrollView
 from being scrolled via touch inputs? I will programmatically get the
 ScrollView to scroll to top or bottom.

 As a last resort, I guess I will have to inherit from ScrollView and
 capture all the ontouch events. But wondering if there is an easier
 way before I take this approach?

 Thanks.

[android-developers] Re: AsyncTask reuse

[Atif Gulzar]

 there is a difference in can be used only once and  single running
instance is allowed

The correct is only single running instance is allowed. Once can get the
status through getStatus and can take action accordingly e.g. cancel


if (YourasynchSubClass.getStatus() == AsyncTask.Status.RUNNING)
YourasynchSubClass.cancel(true);

YourasynchSubClass.execute(parms);

 i must admit i don't quite understand these implementation decisions.
 one-use classes don't make much sense to me. why not make something
 reusable if you can?



 An AsyncTask instance can be used only once indeed. And they're not
 meant to be created/started dozens of times per second so the GC will
 be just fine.

   is it true that AsyncTasks can only be executed once? IMHO they
