Perhaps you want to "sacle" the image to fit the button, something
like:
The image is in Bitmap bm
int width = bm.getWidth();
int height = bm.getHeight();
int newWidth = 32;
int newHeight = 32;
float scaleWidth = ((float) newWidth) / width;
float scaleHeight = ((float) newHeight) / height;
Matrix matrix = new Matrix();
matrix.postScale(scaleWidth, scaleHeight);
Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0,
width, height, matrix, true);
BitmapDrawable bmd = new BitmapDrawable(resizedBitmap);
((ImageButton)this.findViewById(R.id.Yourbutton)).setImageDrawable(bmd);
I hope this helps you, this code works great for me to do the task of
scale an image to a size (in the sample 32x32 as you request)
Best regards.
