问题
I have the following code that will rotate a drawable by a set amount of degrees.
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);
}
The new SDK says that the
BitmapDrawable(canvasBitmap);
is deprecated. Any alternatives at all?

回答1:
Do this instead:
return new BitmapDrawable(context.getResources(), canvasBitmap);
回答2:
Try this Once.
In Activity
BitmapDrawable background = new BitmapDrawable(this.getResources(), blurImageBg);
In Fragment
BitmapDrawable background = new BitmapDrawable(getActivity(), blurImageBg);
In Adapter or else
BitmapDrawable background = new BitmapDrawable(context.getResources(), blurImageBg);
回答3:
Kotlin code for BitmapDrawable
:
var bitmapDrawable = BitmapDrawable(resources,bitmapObj)
