Android--drawable && Bitmap

Bitmap Turn drawable

Bitmap bm=xxx; bitmapdrawable bd=new bitmapdrawable (BM);

Because Btimapdrawable is a subclass of drawable, it is finally possible to use the BD object directly.

drawable turn Bitmap

drawable d=== Bd.getbitmap ();

Finally, BM is the bitmap object we need.

get bitmap from your resources
