不赞成使用BitmapDrawable

我有下面的代码将旋转一个可绘制的一定的度数。

public Drawable rotateDrawable(float angle, Context context) { Bitmap arrowBitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.generic2rb); // Create blank bitmap of equal size Bitmap canvasBitmap = arrowBitmap.copy(Bitmap.Config.ARGB_8888, true); canvasBitmap.eraseColor(0x00000000); // Create canvas Canvas canvas = new Canvas(canvasBitmap); // Create rotation matrix Matrix rotateMatrix = new Matrix(); rotateMatrix.setRotate(angle, canvas.getWidth()/2, canvas.getHeight()/2); //Draw bitmap onto canvas using matrix canvas.drawBitmap(arrowBitmap, rotateMatrix, null); return new BitmapDrawable(canvasBitmap); } 

新的SDK说的

 BitmapDrawable(canvasBitmap); 

已弃用。 任何替代品呢？

做这个，而不是：

 return new BitmapDrawable(context.getResources(), canvasBitmap);
