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:
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:
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:
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();
希望本文所述对大家Android程序设计有所帮助。
