我試圖做出Android提醒,但出現了問題;當我在我的應用程序中設置重複通知時,通知會一直開着,直到我卸載應用程序(刪除重複通知並不會阻止它關閉)。考慮到這一點,當我刪除它們時,我的提醒將從數據庫中刪除。Android重複通知即使在被刪除後也會被觸發

這個問題也是我的重複報警的情況。

我該怎麼辦?

這裏是我的代碼的某些部分:

//數據庫類刪除查詢

public boolean deleteReminder(long rowId) { 

    return mDb.delete(DATABASE_TABLE, KEY_ROWID + "=" + rowId, null) > 0; 
} 

//我怎麼在我的主要活動中刪除提醒

@Override 
public boolean onContextItemSelected(MenuItem item) { 
    switch(item.getItemId()) { 
    case R.id.menu_delete: 
     AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); 
     mDbHelper.deleteReminder(info.id); 
     fillData(); // populate 
     return true; 
    } 
    return super.onContextItemSelected(item); 
} 

ReminderManager .java

public class ReminderManager { 

private Context mContext; 
private AlarmManager mAlarmManager; 

public ReminderManager(Context context) { 
    mContext = context; 
    mAlarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
} 

public void setReminder(Long taskId, Calendar when) { 

    Intent i = new Intent(mContext, OnAlarmReceiver.class); 
    i.putExtra(RemindersDbAdapter.KEY_ROWID, (long)taskId); 

    PendingIntent pi = PendingIntent.getBroadcast(mContext, 0, i, PendingIntent.FLAG_CANCEL_CURRENT); 

    mAlarmManager.setRepeating(AlarmManager.RTC_WAKEUP, when.getTimeInMillis(), 60 * 1000, pi); 
} 
} 

ReminderService.java

public class ReminderService extends WakeReminderIntentService { 

public ReminderService() { 
    super("ReminderService"); 
     } 

@Override 
void doReminderWork(Intent intent) { 
    Log.d("ReminderService", "Doing work."); 
    Long rowId = intent.getExtras().getLong(RemindersDbAdapter.KEY_ROWID); 

    NotificationManager mgr = (NotificationManager)getSystemService(NOTIFICATION_SERVICE); 

    Intent notificationIntent = new Intent(this, ReminderEditActivity.class); 
    notificationIntent.putExtra(RemindersDbAdapter.KEY_ROWID, rowId); 

    PendingIntent pi = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_ONE_SHOT); 

    Notification note=new Notification(android.R.drawable.stat_sys_warning, getString(R.string.notify_new_task_message), System.currentTimeMillis()); 
    note.setLatestEventInfo(this, getString(R.string.notify_new_task_title), getString(R.string.notify_new_task_message), pi); 
    note.defaults |= Notification.DEFAULT_SOUND; 
    note.flags |= Notification.FLAG_AUTO_CANCEL; 

    int id = (int)((long)rowId); 
    mgr.notify(id, note); 


} 
} 

OnAlarmReceiver.java

public class OnAlarmReceiver extends BroadcastReceiver { 

private static final String TAG = ComponentInfo.class.getCanonicalName(); 


@Override 
public void onReceive(Context context, Intent intent) { 
    Log.d(TAG, "Received wake up from alarm manager."); 

    long rowid = intent.getExtras().getLong(RemindersDbAdapter.KEY_ROWID); 

    WakeReminderIntentService.acquireStaticLock(context); 

    Intent i = new Intent(context, ReminderService.class); 
    i.putExtra(RemindersDbAdapter.KEY_ROWID, rowid); 
    context.startService(i); 

} 
}

問題在我的情況是不是取消報警,我不知道爲什麼,當我即使在刪除提醒我他們只是繼續下去。

然後,你在哪裏取消警報?它們不會因爲您刪除應用程序數據庫中的條目而停止。 –

@Mike M,非常感謝。你說得對,我也必須取消我的警報。 – pablo

你將不得不調用AlarmManager.cancel(PendingIntent)完全相同的PendingIntent當你爲了取消了報警電話setRepeating

您應該取消爲重複報警創建的pendingIntent。寫這樣buttonclick代碼將執行

AlarmManager.cancel(的PendingIntent)

請確保您提供您在設置中使用相同的當前事件。否則,與提供的匹配的其他pendingIntent將被取消。
