[android] Android: how to convert whole ImageView to Bitmap?

I have my application that is displaying images with different ratio, resized inside (centerInside) imageView. What I need is to create bitmap from the ImageView including the background (black in this case).

So for example I have device screen 320x480, full screen imageView with image resized to 280x480. How could I get 320x480 bitmap from it?

On top of this imageview I have some logos or buttons that I don't want to include to bitmap, they're like on top layer. All I need is bitmap with image and black border from some sides.

try {
        photo.setImageURI(Uri.parse("Location");
        BitmapDrawable drawable = (BitmapDrawable) photo.getDrawable();
        Bitmap bitmap = drawable.getBitmap();
        bitmap = Bitmap.createScaledBitmap(bitmap, 70, 70, true);
        photo.setImageBitmap(bitmap);

    } catch (Exception e) {

    }

This is a working code

imageView.setDrawingCacheEnabled(true);
imageView.buildDrawingCache();
Bitmap bitmap = Bitmap.createBitmap(imageView.getDrawingCache());

Just thinking out loud here (with admittedly little expertise working with graphics in Java) maybe something like this would work?:

ImageView iv = (ImageView)findViewById(R.id.imageview);
Bitmap bitmap = Bitmap.createBitmap(iv.getWidth(), iv.getHeight(), Bitmap.Config.RGB_565);
Canvas canvas = new Canvas(bitmap);
iv.draw(canvas);

Out of curiosity, what are you trying to accomplish? There may be a better way to achieve your goal than what you have in mind.

You could just use the imageView's image cache. It will render the entire view as it is layed out (scaled,bordered with a background etc) to a new bitmap.

just make sure it built.

imageView.buildDrawingCache();
Bitmap bmap = imageView.getDrawingCache();

there's your bitmap as the screen saw it.

It works in Kotlin after buildDrawingCache() being deprecated

 // convert imageView to bitmap
val bitmap = (imageViewId.getDrawable() as BitmapDrawable).getBitmap()
