How to get an imageView on Full Screen in Android?

I know there are lots of questions like these. However, they all seek to bring imageView on full screen after clicking.

I want to bring an imageView on Full Screen without clicking on it. In other words, when I click my bitmap, I should get a full-screen imageView. I tried a lot but could not achieve desired results.

So far, I have tried this thread's all possible solutions.

Moreover, I tried to use multiple scaling options.

I am self-learning android using a big nerd's ranch guide. I am attaching my code and images below

public View onCreateView(LayoutInflater inflater,
                             ViewGroup parent, Bundle savedInstanceState) {
        imageView=new ImageView(getActivity());
        String path= (String) getArguments().getSerializable(FILE_PATH_NAME);
        BitmapDrawable image = PictureUtils.getScaledDrawable(getActivity(), path);
        float rotation= rotateImage(getActivity(), path);
        Log.i("RotateImagee", "Rotate valuee: " + rotation);
        imageView.setRotation(rotation + 90);
        imageView.setImageDrawable(image);
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
        return imageView;
    }

Images: enter image description here

I want screen fully covered with this image with a proper scaling. Therefore, please show me an appropriate solution with proper scaling.

The fact that the background and Toolbar are greyed-out makes me think you are displaying your ImageView inside a DialogFragment, not a normal Fragment. DialogFragments are a bit different. Getting them to display full screen is a non-trivial task. If you are not trying to display a Dialog then I suggest using a normal Fragment to display the ImageView.

Side notes:

  1. consider rotating the Bitmap, not the ImageView
  2. consider putting the ImageView in a layout file and inflating that layout file (you already have a LayoutInflater passed to you in onCreateView)

You can use only one scaletype and CENTER_INSIDE overrides FIT_XY. Use only FIT_XY. Senconly when you create your ImageView you don't give it layoutparams(default is wrap_content), so you need to set layoutparams to match_parent. Without it imageView will change size to wrap_content and FIT_XY will not take affect.

Here is a link if you want to make activity full screen. you also need to remove ActionBar, Here.
