How to show imageView full screen on imageView click?

Question

I am getting images from url and showing it on the imageView. This functionality is working properly. But I want that when I click on that image, then it must be full screen

Answer 1

Yes I got the trick.

public void onClick(View v) {

            if( Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH ){
                imgDisplay.setSystemUiVisibility( View.SYSTEM_UI_FLAG_HIDE_NAVIGATION );

            }
            else if( Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB )
                imgDisplay.setSystemUiVisibility( View.STATUS_BAR_HIDDEN );
            else{}

    }

But it didn't solve my problem completely. I want to hide the horizontal scrollview too, which is in front of the imageView (below), which can't be hidden in this.
