Android three ways to implement no title bar fullscreen

One, through the Java code

Prior to Setcontentview execution:

Requestwindowfeature (Window.feature_no_title); // hides the title bar GetWindow (). SetFlags (Windowmanager.layoutparams.flag_fullscreen,windowmanager.layoutparams.flag_ fullscreen); // Hide the status bar

Second, call Android to bring your own theme

Add the activity properties directly in the androidmanifest.xml that require full-screen display

Android:theme= "@android: Style/theme.notitlebar.fullscreen"  //android:theme= " Theme.Light.NoTitleBar.Fullscreen "  //  white background, no title bar, full screen android:theme=" Theme.Black.NoTitleBar.Fullscreen "  //

Three, define your own full screen theme

Define theme in the Style.xml file (if not style.xml, created in the Res/values directory)

<Resources>     <stylename= "Theme.notitle_fullscreen"><!--a custom theme name--<Itemname= "Android:windownotitle">True</Item>            <Itemname= "Android:windowfullscreen">True</Item>          </style> </Resources>

Add the activity properties directly in the androidmanifest.xml that require full-screen display

Android:theme= "@style/theme.notitle_fullscree"
