"Android" Hide bottom virtual keys

Google's official documents are:

Https://developer.android.com/training/system-ui/navigation.html#behind

Sample code

1 View decorview = GetWindow (). Getdecorview (); 2//Hide both the navigation bar and the status Bar.3//system_ui_flag_ful Lscreen is only available on Android 4.1 and higher, but AS4//a general rule, you should design your app to hide the STA Tus bar whenever you5//hide the navigation bar.6 int uioptions = view.system_ui_flag_hide_navigation7               | View.system_ui_flag_fullscreen;8 decorview.setsystemuivisibility (uioptions);

Original:

However, there is a problem.

This can really hide the bottom virtual navigation bar, but once you tap the screen, the navigation bar will appear (for about 1 seconds) and consume your click events. If you want to click a button (the navigation bar is hidden), you need to point two times in a row. Because the navigation bar disappears after 1 seconds, clicking on the screen event will block the consumption again.

The Final Solution

  /**     * Hide virtual keys and full screen     *    /protected void Hidebottomuimenu () {        //Hide virtual keys, and fullscreen        if (Build.VERSION.SDK_ INT > One && Build.VERSION.SDK_INT < +) {//Lower API            View v = This.getwindow (). Getdecorview ();            V.setsystemuivisibility (View.gone);        } else if (Build.VERSION.SDK_INT >=) {            //for new API versions.            View Decorview = GetWindow (). Getdecorview ();            int uioptions = View.system_ui_flag_hide_navigation                            | View.system_ui_flag_immersive_sticky | View.system_ui_flag_fullscreen;            Decorview.setsystemuivisibility (uioptions);        }    }
