Trouble centering a bitmap on an ImageView

Question

I have an ImageView (image_view) in an xml and I have the layout gravity set to center and the scale set to center_inside....but when I pass my compressed bmp to the image_view, it puts it on the middle-left of the screen (in portrait mode)...any ideas on a workaround?

here is me setting it to the image view:

        ImageView imageView = (ImageView) findViewById(R.id.image_view);

        imageView.setImageBitmap(bitmap565);

I also compress it in an output stream:

        try {
            FileOutputStream fos = new FileOutputStream(filepath);

            bitmap565.compress(CompressFormat.JPEG, 90, fos);

            fos.flush();
            fos.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

Thanks all!

you can solve your problem just using FrameLayout.
