本文实例讲述了Android4.0平板开发之隐藏底部任务栏的方法。分享给大家供大家参考,具体如下:
复制代码 代码如下:getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);//隐藏底部任务栏代码
上边已验证
下边百度过来的
showBar显示任务栏
closeBar隐藏任务栏
前提:需要ROOT权限
public static void showBar() { try { Process proc = Runtime.getRuntime().exec( new String[] { "am", "startservice", "-n", "com.android.systemui/.SystemUIService" }); proc.waitFor(); } catch (Exception e) { e.printStackTrace(); } } public static void closeBar(Context context) { try { // 需要root 权限 Build.VERSION_CODES vc = new Build.VERSION_CODES(); Build.VERSION vr = new Build.VERSION(); String ProcID = "79"; if (vr.SDK_INT >= vc.ICE_CREAM_SANDWICH) { ProcID = "42"; // ICS AND NEWER } // 需要root 权限 Process proc = Runtime.getRuntime().exec( new String[] { "su", "-c", "service call activity " + ProcID + " s16 com.android.systemui" }); // WAS 79 proc.waitFor(); } catch (Exception ex) { Toast.makeText(context, ex.getMessage(), Toast.LENGTH_LONG).show(); } }
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:
复制代码 代码如下:requestWindowFeature(Window.FEATURE_NO_TITLE);
或者
复制代码 代码如下:android:theme="@android:style/Theme.Black.NoTitleBar
显示:
复制代码 代码如下: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:
复制代码 代码如下:# 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();
