问题描述
在我的应用中,我想让用户隐藏或显示导航栏(后退,主页,菜单).系统栏(电池,wifi,通知)应始终处于隐藏状态.
In my app I want to let the user hide or show the Navigation Bar (back, home, menu). The System Bar (battery, wifi, notifications) should always be hidden.
我用以下代码隐藏系统栏:
I hide the System Bar with this code:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);
并且我成功隐藏了带有以下标志的导航栏:
And I am successfully hiding the Navigation Bar with these flags:
final static int flagsHide = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
但是我还没有发现如何再次显示导航栏.我可以用标志来做还是需要其他东西?系统栏必须保持不可见.
But I haven't found on how to show the Navigation Bar again. Can I do that with flags or do I need something else? The System Bar has to stay invisible.
推荐答案
使用此标志再次显示它
SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN |
SYSTEM_UI_FLAG_LAYOUT_STABLE
