Answer 1

bottom Navigation bar也是你布局文件中的view，你可以这样：

    setContentView(R.layout.activity_main);
    BottomNavigationView bottomNavigationView = (BottomNavigationView)
                    findViewById(R.id.navigation);
    bottomNavigationView.setVisibility(View.INVISIBLE); //In activity you want to hide it
    bottomNavigationView.setVisibility(View.VISIBLE); //In activity you want to show it
