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
隱藏:
requestWindowFeature(Window.FEATURE_NO_TITLE);
或者
android:theme="@android:style/Theme.Black.NoTitleBar
顯示:
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
3.NotificationBar、StatusBar、SystemBar
Dim的話可以:
getWindow().getDecorView().setSystemUiVisibility
(View.SYSTEM_UI_FLAG_LOW_PROFILE);
隱藏的話可以(不好使,哈哈):
getWindow().getDecorView().setSystemUiVisibility
(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
那怎麼玩呢?用狠招吧,哈哈:
命令行方式:
直接用進程號殺,不加service那個shell的話,一會SystemBar會自啟動。
# kill com.android.systemui
# service call activity 79 s16 com.android.systemui
如果想啟動SystemBar:
# am startservice -n com.android.systemui/.SystemUIService
代碼方式:
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();
