Here is a small sample that will rotate a bitmap.
Bitmap animation = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.eye_rotate, mBitmapOptions); Bitmap bitmap = Bitmap.createBitmap(animation.getWidth(), animation.getHeight(), BITMAP_CONFIG); bitmap.setDensity(DisplayMetrics.DENSITY_DEFAULT); Matrix matrix = new Matrix(); matrix.reset(); matrix.setTranslate(0, 0); matrix.postRotate(degrees, (animation.getWidth()/2), (animation.getHeight()/2)); Canvas canvas = new Canvas(bitmap); Paint paint = new Paint(); int xPos = 0; int yPos = 0; Rect src = new Rect(xPos, yPos, xPos + animation.getWidth(), yPos + animation.getHeight()); Rect dst = new Rect(0, 0, animation.getWidth(), animation.getHeight()); canvas.drawBitmap(mBackground, src, dst, paint); canvas.drawBitmap(animation, matrix, null); |
