Make ImageView fullscreen on click

I have a view with two images

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/top_section"
        android:orientation="vertical"
        android:layout_marginTop="120dp">

    <ImageView
            android:layout_width="match_parent"
            android:layout_height="170dp"
            android:id="@+id/top_image"/>

    <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/top_text"/>
</LinearLayout>

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/bottom_section"
        android:orientation="vertical"
        android:layout_alignParentBottom="true">

    <ImageView
            android:layout_width="match_parent"
            android:layout_height="170dp"
            android:id="@+id/bottom_image"/>

    <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/bottom_text"/>
</LinearLayout>

I would like to make it so that if user clicks image view it becomes full screen and rotates properly to take up full screen.

So far I have tried (for example if top section is clicked)

topText.setVisibility(View.GONE)
bottomSection.setVisibility(View.GONE)
getSupportActionBar().hide();
getActivity().getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

But image is not really full screen. How would I go about making image full screen? I have been thinking of maybe having one third image view and make that be match parent for width and height and have it become visible on click.

Create another activity called ImageZoomedActivity, pass the image data to it through the intent (it could be an url, local file location etc..) and in the OnCreate method :

requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.popup_photo_full);
    supportPostponeEnterTransition();
    if(getIntent().hasExtra("file")) {
        imageFile = new File(getIntent().getStringExtra("file"));
        GlideApp.with(this).asBitmap()
                .load(imageFile)
                .into(image);
        supportStartPostponedEnterTransition();
    }

The code above works with a local file URI passed through the intent.

These two lines

requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

let you make the activity in full screen. It's possible, also, to make a transition between the first activity with the thumbnail and the second one with the full-screen image. If you want to know more send me a pm, I can send you the detailed code to do that.
