BitmapDrawable deprecated alternative

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)
