如何隐藏Android4.0及以上版本的ActionBar、NotificationBar、StatusBar、SystemBar、TitleBar .

1.ActionBar:

        <activity android:name="Demo"                   android:label="@string/app_name"                    android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >             <intent-filter>                 <action android:name="android.intent.action.MAIN" />                 <category android:name="android.intent.category.LAUNCHER" />             </intent-filter>         </activity> 2.TitleBar 隐藏: requestWindowFeature(Window.FEATURE_NO_TITLE); 或者 android:theme="@android:style/Theme.Black.NoTitleBar 显示: 
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 


3.NotificationBar、StatusBar、SystemBar

Dim的话可以:

getWindow().getDecorView().setSystemUiVisibility   (View.SYSTEM_UI_FLAG_LOW_PROFILE); 

隐藏的话可以(不好使,哈哈):

getWindow().getDecorView().setSystemUiVisibility   (View.SYSTEM_UI_FLAG_HIDE_NAVIGATION); 

那怎么玩呢?用狠招吧,哈哈:

命令行方式:

直接用进程号杀,不加service那个shell的话,一会SystemBar会自启动。

# kill com.android.systemui

# service call activity 79 s16 com.android.systemui

如果想启动SystemBar:

# am startservice -n com.android.systemui/.SystemUIService

代码方式:

要root啊,

Process proc = Runtime.getRuntime().exec(new String[]{"su","-c","service call activity 79 s16 com.android.systemui"});
proc.waitFor();

Process proc = Runtime.getRuntime().exec(new String[]{"am","startservice","-n","com.android.systemui/.SystemUIService"});
proc.waitFor();
