如何转换一个可绘制位图？

Question

I would like to set a certain Drawable as the device's wallpaper, but all wallpaper functions accept Bitmaps only. I cannot use WallpaperManager because I'm pre 2.1.

Also, my drawables are downloaded from the web and do not reside in R.drawable.

Answer 1

This converts a BitmapDrawable to a Bitmap.

Drawable d = ImagesArrayList.get(0);  
Bitmap bitmap = ((BitmapDrawable)d).getBitmap();
