本文實(shí)例講述了Android4.0平板開(kāi)發(fā)之隱藏底部任務(wù)欄的方法。分享給大家供大家參考,具體如下:
復(fù)制代碼 代碼如下:getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);//隱藏底部任務(wù)欄代碼
上邊已驗(yàn)證
下邊百度過(guò)來(lái)的
showBar顯示任務(wù)欄
closeBar隱藏任務(wù)欄
前提:需要ROOT權(quán)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 權(quán)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 權(quán)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
隱藏:
復(fù)制代碼 代碼如下:requestWindowFeature(Window.FEATURE_NO_TITLE);
或者
復(fù)制代碼 代碼如下:android:theme="@android:style/Theme.Black.NoTitleBar
顯示:
復(fù)制代碼 代碼如下: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);
那怎么玩呢?用狠招吧,哈哈:
命令行方式:
直接用進(jìn)程號(hào)殺,不加service那個(gè)shell的話,一會(huì)SystemBar會(huì)自啟動(dòng)。
# kill com.android.systemui# service call activity 79 s16 com.android.systemui
如果想啟動(dòng)SystemBar:
復(fù)制代碼 代碼如下:# 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();
