Android:如何移动BitmapDrawable？

BitmapDrawable originalDrawable = (BitmapDrawable) getResources().getDrawable(R.drawable.original_image);
Bitmap originalBitmap = originalDrawable.getBitmap();

int width = originalBitmap.getWidth();
int height = originalBitmap.getHeight();

Bitmap newBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(newBitmap);
canvas.drawBitmap(originalBitmap, 0, 0, null);

int offsetX = 100; // 水平方向上的偏移量
int offsetY = 100; // 垂直方向上的偏移量
canvas.translate(offsetX, offsetY);

BitmapDrawable movedDrawable = new BitmapDrawable(getResources(), newBitmap);
imageView.setImageDrawable(movedDrawable);
