OnBackPressed和onOptionsItemSelected在棒棒糖中不工作

我有一個活動，只要調用onBackPressed或onOptionsItemSelected，就可以調用上一個活動。我的代碼正在開發Kitkat，冰淇淋和棉花糖。它只是在棒棒糖不工作。這是爲什麼？OnBackPressed和onOptionsItemSelected在棒棒糖中不工作

我的動態

@Override 
public void onBackPressed() { 
    super.onBackPressed(); 

} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    super.onOptionsItemSelected(item); 
    return NavUtils.navigateUpFromSameTask(this); 

}

Android清單

<activity 
     android:name=".Activities.ReminderActivity" 
     android:screenOrientation="portrait" 
     android:label="@string/title_reminder_activity"> 

     <meta-data 
      android:name="android.support.PARENT_ACTIVITY"

您的代碼在哪裏返回onOptionsItemSelected（）中的上一個活動？我的意思是，onBackPressed很清楚，它會自動執行，但是在選擇的項目中，必須有一些finish（）調用或liek我在Manifest中看到一些'NavUtils.navigateUpFromSameTask（this）;'調用 – Opiatefuchs

'lollipop' ？ 'logcat'？ – Max

不要重寫onBackPressed（）{ – Haroon

onOptionsItemSelected是當你要調用invalidateOptionsMenu()被召回的方法。
