据我所知，在清单中这些属性：

I understand that these properties in the manifest:

android:theme="@android:style/Theme.NoTitleBar"     
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

可以去掉标题栏。 不过，我不断检查图形布局，当我修改我的应用程序。当我看图形布局我仍然可以看到标题栏。我想删除标题栏的，我没有游戏的开发过程中看到它的方式。

can remove the title bar. However, I constantly check the Graphical Layout when I am modifying my app. When I look at the Graphical Layout I still see the title bar. I want to remove the title bar in a way that I don't have to see it during the development of the game.

推荐答案

在工具栏下方的标签栏，有一排图标。点击一个看起来像一个明星，然后去全部 - ＆GT; Theme.NoTitleBar（.Fullscreen）

On the toolbar directly below the tab bar, there is a row of icons. Click on the one that looks like a star, then go to All -> Theme.NoTitleBar(.Fullscreen)
