那么，如果你正在尝试动态显示和已经提到的窗口，我不知道，如果你能做到这一点与官方的窗口标题，由于注意活动的生命周期中隐藏它的功能需要被前设置的setContentView（）被调用。
Well if you are trying to dynamically show and hide it during the lifetime of the activity I am not sure if you can do that with the official Window Title due to the note that has been mentioned about window features needing to be set before setContentView() is called.
一件事，你可以做的是实现自己的标题栏和动态显示和隐藏...我放在一起这个例子应该设置你O n此正确的轨道
One thing that you could do is implement your own title bar and dynamically show and hide that... I put together this example that should set you o nthe right track
由于当你改变方向，您的应用程序经过一系列生命周期的变化，你必须在的onCreate 一个机会来显示或隐藏的标题。
Since when you change orientation, your app goes through a set of lifecycle changes, you have an opportunity in onCreate to show or hide your title.

或者你干脆指定一个不同的布局风景模式：
Or you specify a different layout altogether for landscape mode:

景观布局
当你想为景观不同的设计，把你的布局XML文件中/ RES /布局的土地。当布局更改Android将自动看这里。如果没有这种特殊的地貌布局定义，Android将伸展的默认布局。
When you want a different design for landscape, put your layout XML file inside /res/layout-land. Android will automatically look here when the layout changes. Without this special landscape layout defined, Android will stretch the default layout.
