Sorry if this is an already answered question. I'm new to Android programming and to this (fantastic) board.
I'm trying to implement some stupid solitaire game just for the sake of learning something about Android, but I realized my images are too big. I tried searching for methods to simply do this but I cannot find anything useful.
Does any of you knows a very simple way to resize the image?

I have something like this:

Is it possible to resize the bitmap inside c with very simple steps?
Thanks

I solved the problem using a big function that resizes it. I think it would be better for the developers of the API to introduce some kind of function in the Bitmap class like .changeWidth(int value) or .changeHeight(int value).
Anyhow to whom it may concern, here is the solution I adopted.


Hope it helps!

thanks for the share of your function I was looking for something like this ^^

nice, but instead of 20 lines use one-liner: createScaledBitmap

http://developer.android.com/intl/fr/re ... ics.Bitmap, int, int, boolean)

Yeah i just found that one too.

Only I wanted to use this code to resize a bitmap to use for a wallpaper.

Code: Select all

Bitmap mBitmap = BitmapFactory.decodeResource(getResources(), uri);
                try {                   
                   Bitmap resized;     
                   Display display = getWindowManager().getDefaultDisplay();
                   int newHeight = display.getHeight();
                   int newWidth = display.getWidth(); 
                   resized = Bitmap.createScaledBitmap(mBitmap, newWidth, newHeight, false);                   
         wallpaperManager.setBitmap(resized);

         int temp = resized.getHeight();
                   int temp2 = mBitmap.getHeight();


It resizes the bitmap, but I suspect Android OS resizing it again when you use it as a wallpaper -.-

temp contains 400 and temp contains 440. But both situations look the same when I set them as bitmap for WallPaperManager
Back to investigating this problem =(
