Android :: Way To Scale Drawable Passed To TextView.setCompoundDrawables
Oct 6, 2010
Is there a way to scale the Drawable passed to TextView.setCompoundDrawables ? The following code works very well but of course is set to the full intrinsic size of the drawable. This code is used with the Holder pattern in a ListView where the purpose is to update the drawable without two more Views (LinearLayout and ImageView) to accomplish the same thing. code...
I suppose I can use Drawable.setBounds() and preserve the original aspect ratio with a small function but just wondering if there this a more direct way to do this with the api?

On a layout I want to scale the background image (keeping its aspect ratio) to the space allocated when the page gets created. I am using layout.setBackgroundDrawable() and am using a BitmapDrawable to setGravity for clipping and filling, but don't see any option for scaling.

I need to know how he takes drawable object. I'm collecting some ImageView objects in array, they have background images that are rather big in resolution so they take lot of memory...
I have read somewhere that it will automatically create image with resolution that my imageView have, so i think it will take less memory than first one. Please tell me, if i set scaleType property, will it scale that image? Will that help me to save memory?

I'm trying to create a method for resizing multi-line text in a TextView such that it fits within the bounds (both the X and Y dimensions) of the TextView. At present, I have something, but all it does is resize the text such that just the first letter/character of the text fills the dimensions of the TextView (i.e. only the first letter is viewable, and it's huge). I need it to fit all the lines of the text within the bounds of the TextView.

I'm battling with extending a TextView for my Android app. I'd like to create "bubbles" to display text messages in a conversation, similar to the native iPhone SMS conversations.
Is there a way to implement the resizing of a background image without just stretching it? I'd like to have a single background image that keeps it's corners but get stretched only in defined areas. I think this should be possible because I've seen it in a SMS app, but I wonder how to implement that.

I am trying to get those nicely looking android list dividers above and below a TextView. This is how far I am. code...
The ImageView makes what I want - a scaled to fill the parent separator, but this is somewhat not an ideal solution. The android:drawable* in the TextView do not scale to fill the parent - any ideas how to achieve this?

I was wondering if there is a way to determine who passed an intent to my application. For example, I have a service, that I want to act differently depending on who passed the intent (for security reasons). I'm trying to sandbox each calling application, so they only have access to their data stored in my application.
For it to be secure, I cannot trust any application to be truthful about the identifying data it is passing into my service. Therefore, I need some system way of identifying who sent the intent in a way that the calling application cannot change that information. I don't know if it is possible, but I can't find anything in the Intent class, and I was wondering if there may be another structure which does what I want it to. If it is not possible, I would like to get some type of mechanism to do this in the roadmap.

I am writing a music player for esoteric music formats, and have defined mime types for them in my Manifest.
However, the standard music player is always started even though it can't handle the format. Looking at logcat I see;
: D/MediaScannerService( 688): IMediaScannerService.scanFile: / sdcard/download/Cybernoid.sid mimeType: audio/prs.sid : I/ActivityManager( 578): Stopping service: com.android.providers.media/.MediaScannerService : I/ActivityManager( 578): Starting activity: Intent { action=android.intent.action.VIEW data=file:///sdcard/download/ Cybernoid.sid type=audio/prs.sid flags=0x4000000 comp={com.android.music/com.android.music.MediaPlaybackActivity} }
.. so it seems the component is explicitly set to the music player ? Is there any way around this ?

Why below code is throwing nullPointer exception in last line (when accessing javaInterface.mValue) This line through NullPointer, so basically it is not being set. even though the javascript is correct and has been verified using FireBug that it returns expected string.
There are few lines above this code chunk but it is irrelevant this problem

I have an activity that implements LocationListener in my application and my onLocationChanged method has been working perfectly up until recently. For some reason the Location object being passed into the method is null. My question is, why is it null? Does it pass in a null object if it cannot acquire a location?
My GPS is on and I have it set to pull a location from the GPS, and I know my GPS can get a fix on me as I used Maps and had it locate me.
Also, I have the permission for my app set as:
CODE:.................
I don't believe permissions is the issue though, as my activity was working beforehand and I have not altered the permissions since then.
Here is the code that determines the provider of the location object:
CODE:.............
Here is the LogCat output of the error:
CODE:..............
I have tested the same code on another device (an HTC MyTouch 3G to be precise) and it works flawlessly with the GPS, however on my Motorola Droid it crashes.

This subject originates here: http://groups.google.com/group/android-beginners/browse_thread/thread...
To sum up:
When I click on an item in the ListView, the background color that gets changed is not that of the clicked item but instead of the other item in the opposite side relative to the middle item:
1 <-- I click here 2 3 <-- Acts as a mirror 4 5 <-- This is the one that gets changed
1 2 <-- This is the one that gets changed 3 <-- Acts as a mirror 4 <-- I click here 5
This problem persists even when I use CheckedTextView like what is suggested in the post.
I use the latest stable SDK.
This problem occurs when the target platform is Android 1.6, 2.0 or 2.0.1.
The problem does not occur when the target platform is Android 1.1 or 1.5.
However, the problem will also occur when the program is compiled for 1.5 and run in 2.0.1.
The simple problematic code can be found here: [url]
There I also put the screenshots showing the problem: demo01.png: I click an item. demo02.png: the clicked item doesn't get changed but the reflective item does.
Is this a bug in newer Android platforms?
If it is intended, what is the reason and could you please show me how I should fix my code?

I have an application where I navigate from Activity A to Activity B and back to A and then B. I want to resume the activity B (which has a Bundle passed to it ) from Activity A. The documentation says that OnSaveInstance() is called only when the activity is killed, so how do i use OnPause which does not have the Bundle to resume the activity B.

I have a service that regularly queries a web server for new messages. The service stores the new messages in an arrayList. These messages are implemented using a custom class, storing all kinds of metadata (strings and longs).
An activity then connects to this service to retrieve those messages and display them to the user.
I have an .aidl file that describes the interface that the service exposes.
CODE:..........
The Message class extends the Parcelable class which should allow for the IPC transfer.
The problem is this: Eclipse gives me an error saying that the type of List<Message> is unknown. Any imports are marked as invalid.

While doing normal day-to-day Android development, is it safe to assume that hook methods called by the system will not pass in invalid references (ex.: null), or should I always be double-checking what arguments get passed in?For example, can the method onOptionsItemSelected(MenuItem) ever have a null MenuItem reference passed into it?The reason I ask is because I was working on the Notepad 1 tutorial,I started wondering if I should be testing if item is null before making a getItemId() method call on it, or just trust the system to not ever pass me a null?I don't want to make my code slower by doing null checks when I shouldn't be worried about that happening, etc.

I have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.

I'm trying to create a textView in the parent activity onActivityResult but the textView does not appear. There is an ImageView that takes up the whole parent activity. I can create a textView and place it, and it should go on top of the imageView?
In the parent class:
[HIGH]private void addClothes(int menuId) {
Intent chooseClothesIntent = new Intent(this, ChooseClothesActivity.class);
chooseClothesIntent.putExtra("menuId", menuId);
startActivityForResult(chooseClothesIntent, 1);
}[/HIGH]
[Code]...
then in my new activity:
[HIGH]@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
try {
ClothingItem ci = mListContents.get(position);
String imagePath = ci.getImagePath();
[Code]...
