我有一个观点。我希望把位图图像作为背景图像。我没能做到这一点。

I have a view. I want to place a bitmap image as its background image. I was not able to do that.

//My code is below

Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.grape);
part1 = new View(this); 
Bitmap map2 = Bitmap.createBitmap(targetWidth, targetHeight,Bitmap.Config.ARGB_8888);
canvas.drawBitmap( bitmapOrg,new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight()), new Rect(0, 0, targetWidth, targetHeight), null);

part1.setBackgroundResource(map2); //i couldn't place map2 as bgresource to my view part1

谁能帮助？

推荐答案

根据API文档，setBackgroundResource预计一个int。

According to the API docs, setBackgroundResource expects an int.

如果你肯定需要一个位图，你可以使用setBackgroundDrawable反而，敷在BitmapDrawable.

If you definitely need a bitmap, you can use setBackgroundDrawable instead and wrap your bitmap in a BitmapDrawable.
