On a layout I want to scale the background image (keeping it's aspect ratio) to the space allocated when the page gets created. Anyone have any idea how to do this?
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 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 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.
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?
I've created a custom ViewGroup (based off of the Launcher) that allows paging scrolls between some WebViews. Problem is that it doesn't scroll as smoothly as I want it to. I've been following Romain Guy's 2008 advice, but I don't see any massive improvements. Is it because I am using WebViews, or am I just doing the prescaling wrong? This is my code:
Bitmap originalImage = BitmapFactory.decodeResource(getResources(), R.drawable.redbg);
originalImage = Bitmap.createScaledBitmap( originalImage, // bitmap to resize ((WindowManager)
getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getWidth(),
// new width ((WindowManager)getSystemService(Context.WINDOW_SERVICE))
.getDefaultDisplay().getHeight(), // new height true); // bilinear filtering
getWindow().setBackgroundDrawable(new BitmapDrawable(originalImage));
called from onCreate. Is the right?
I have an image, say 16px from our designer. I want to Set it as the background image on a view, but the view is larger than the image. So I want to anchor the image at the top of the view, and then have the view fill in the bottom with a solid color.
Is this possible in the current version of android, 1.5_r3?
Here is what I have so far, but the image is scaling to take up the entire view, and I am not sure how to set the image as background and specify a solid color at the same time. I suspect I need to wrap the view in a containing view which has the color specified, is that the best way to do it? code...
I have a tab layout with drawable resources as tab images.
In landscape mode everything fine. But in portrait mode images doesn't have some margin from tabs. How I can change images scale or how to set some margin to image? I don't want use fixed size, don't think that it is right way.

In android, I defined an ImageView's layoutWidth to be 'fill_parent' (which takes up the full width of the phone). My question is if the Image i put to ImageView is bigger than the layoutWidth, android will scale it, right? But what about the height? when android scale it, will it keeps the aspect ratio? What I find out is, there is some 'white space' at the top/bottom of the ImageView when android scales an image which is bigger than the ImageView. Is that true? If yes, how can I eliminate that white spaces?

I really appreciate if someone can help me with using how to use shape drawable as my background xml for my view. This is what I tried: But I never get the color. Android always gives me black text on white background, regardless what color attribute I put.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"

I have a GLSurfaceView with a drawable as background, however only the background is visible when rendered without surfaceView.setZOrderOnTop(true)I need to avoid using setZOrderOnTop(true) because there are static TextView's being used on top of the GLSurfaceView. Any suggestions for getting this to work?
View 2 Replies View RelatedJust like Twitter for android used to have (they removed it) - I need to display an animated background drawable.
How to I show an image that is actually bigger then the given layout dimensions (without the image being shrink).
What kind of animation do I need to use for the "moving" effect?
I have an activity which uses android:theme="@android:style/Theme.Dialog". The activity contains an ImageView which can show images of different dimensions. The ImageView should scale the Image so that it entirely fits into the window, at least on axes fits entirely and maintains the original aspect ratio. The size of the dialog should only be as large as the ImageView (plus its border width).
I tried the following but the dialog window always uses the whole available space:

I have an app that I started in 1.6. It used images that were specific to portrait and landscape layouts. I put these in the corresponding drawable folders, for example:
drawable/image01,png
drawable-land/image01.png
when I created a new project with 2.0 it gave me the following folders. drawable drawable-hdpi drawable-mdpi drawable-lpdi. when I look at the documentation around these folders it all seems very straight forward. I assumed that you were able to create the following folders. drawable-hdpi-land drawable-mdpi-land drawable-lpdi-land
and everything would work as before. The image directory would swap automagically pulling the appropriately laid out image depending on your screen orientation. Unfortunately it does not. The SDK seems to get confused, and if I clean the project, the folders come up as poorly named.
I want to show image from drawable folder using path (res/drawable/icon.png). I do not want to use R.drawable.icon. Please anybody know how to view the image using res/drawable/icon.png.
View 6 Replies View RelatedI am trying to create a drawable in code and change the color based on some criteria. When I try and set the Drawable as the background of the ImageView it displays but won't let me set any padding. I realized I need to set the ImageView image via the setImageDrawable() function in order to be able to set the padding. The problem I am running into is that when I set it via the setImageDrawable() function nothing is displayed.
Here is what I have written:
<?xml version="1.0" encoding="utf-8"?>
ImageView icon = (ImageView) row.findViewById(R.id.icon);
ShapeDrawable mDrawable; int x = 0; int y = 0;
int width = 50; int height = 50;
float[] outerR = new float[] { 12, 12, 12, 12, 12, 12, 12, 12 };
mDrawable = new ShapeDrawable(new RoundRectShape(outerR, null, null));
mDrawable.setBounds(x, y+height, x + width, y);
switch(position){ case 0: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 1: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 2: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 3: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 4: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 5: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 6: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 7: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 8: mDrawable.getPaint().setColor(0xffffff00); //Yellow break;
case 9: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 10: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 11: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 12: mDrawable.getPaint().setColor(0xffa020f0); //Purple break;
case 13: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 14: mDrawable.getPaint().setColor(0xffffd700); //Gold break;
case 15: mDrawable.getPaint().setColor(0xffff6600); //Orange break;
} icon.setImageDrawable(mDrawable); icon.setPadding(5, 5, 5, 5);
This results in a space for the ImageView but no image.
I have to make a dedicated image viewer app for Android 2.x.
There are too many jpeg image files: about 2000~ jpegs, over 100MB.
I want access the image files with their file names,
but I couldn't find such an example.
By the way, is it okay to put many image files in /res/drawable folder?
I heard that the android application cannot be installed on sdcard and
the program repository is very small so 100MB app cannot be installed generally.
I found some examples which download the large data files on sdcard online,
but I cannot run a web server to host the data files,
and I must upload the fully packaged program on Android Market. (Should I build one apk file?)
What are the best practices for managing too many resource images (or something) in Android?
How can i convert a Bitmap to Drawable.
