此方案在频幕有交互操作时状态栏和导航栏还会出来

private static Handler sHandler;

protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);

    sHandler = new Handler();

    sHandler.post(mHideRunnable); // hide the navigation bar

    final View decorView = getWindow().getDecorView();
    decorView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener()
        {
            @Override
            public void onSystemUiVisibilityChange(int visibility)
            {
                sHandler.post(mHideRunnable); // hide the navigation bar
            }
        });
}

Runnable mHideRunnable = new Runnable() {
    @Override
    public void run() {
        int flags;
        int curApiVersion = android.os.Build.VERSION.SDK_INT;
        // This work only for android 4.4+
        if(curApiVersion >= Build.VERSION_CODES.KITKAT){
            // This work only for android 4.4+
            // hide navigation bar permanently in android activity
            // touch the screen, the navigation bar will not show
            flags = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                  | View.SYSTEM_UI_FLAG_IMMERSIVE
                  | View.SYSTEM_UI_FLAG_FULLSCREEN;

        }else{
            // touch the screen, the navigation bar will show
            flags = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;
        }

        // must be executed in main thread :)
        getWindow().getDecorView().setSystemUiVisibility(flags);
    }
};
