一、在AcdroidMainfest.xml中
<application android:label="App1" android:theme="@android:style/Theme.NoTitleBar"></application>
方法二、
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
//隱藏標題欄(須放在SetContentView函數之前)
this.RequestWindowFeature(WindowFeatures.NoTitle);
//設置全屏
this.Window.SetFlags(WindowManagerFlags.Fullscreen, WindowManagerFlags.Fullscreen);
SetContentView(Resource.Layout.Main);
}
