If you just want the Bitmap from a ImageView the following code may work for you:-

Bitmap bm=((BitmapDrawable)imageView.getDrawable()).getBitmap();

I think that's what you wanted.

Answer 2

If your drawble is not always an instanceof BitmapDrawable

Note: ImageView should be set before you do this.

Bitmap bitmap;
if (mImageView.getDrawable() instanceof BitmapDrawable) {
    bitmap = ((BitmapDrawable) mImageView.getDrawable()).getBitmap();
} else {
    Drawable d = mImageView.getDrawable();
    bitmap = Bitmap.createBitmap(d.getIntrinsicWidth(), d.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    d.draw(canvas);
}

Your bitmap is stored in bitmap.

Voila!

Easiest way is to set tag in ImageView.

imageView.setImageBitmap(bitmap);
imageView.setTag(bitmap); 

To get Tag from it

imageView.getTag();
