BitmapDrawable bitmapDrawable = (BitmapDrawable)bitmap;   
Drawable drawable = (Drawable)bitmapDrawable;   
  
  
Bitmap bitmap = new Bitmap (...);   
Drawable drawable = new BitmapDrawable(bitmap);

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

BitmapDrawable bitmapDrawable = (BitmapDrawable)bitmap;这一句应该改成BitmapDrawable bd = new BitmapDrawable(bitmap);
