Android重复通知即使被删除也会消失

我曾尝试制作Android提醒,但出现了问题;当我在我的应用程序中设置重复通知时,通知会继续触发,直到我卸载应用程序(删除重复通知并不会阻止它关闭)。考虑到这一点,我删除它时会从数据库中删除我的提醒。

我的重复警报也是如此。

我该怎么办?

以下是我的代码的一些部分:

//数据库类中的删除查询

public boolean deleteReminder(long rowId) {

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

//如何删除主要活动中的提醒

 @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);

}
}

修改

在我的情况下,问题不是取消警报,我想知道为什么当我甚至删除我的应用程序中的提醒时,他们就会继续关闭。

当您致电AlarmManager.cancel(PendingIntent)以取消闹钟时,您必须使用完全相同的PendingIntent致电setRepeating

答案 1 :(得分:0)

您应该取消为重复闹钟而创建的pendingIntent。编写类似buttonclick的代码来执行

AlarmManager.cancel(的PendingIntent)

确保您提供的是与设置中使用的相同的待处理事件。否则,与提供的匹配的其他pendingIntent将被取消。
