Answer 1

i suggest to try this and scale your image use matrix class.

Bitmap bmp = BitmapFactory.decodeResource(myContext.getResources(),drawableId);
            int w = bmp.getWidth();
            int h = bmp.getHeight();


Matrix bMatrix = new Matrix();
            bMatrix.postScale(scaleWidth, scaleHeight);
            Bitmap resizedBitmap = Bitmap.createBitmap(bmp, 0, 0, w, h , bMatrix, true);
