为什么android.intent.action.TIME_SET多次调用我的BroadcastReceiver onReceive

Question

1）android.intent.action.BOOT_COMPLETED工作正常，只调用广播onReceive一次

2）当用户手动更改多次调用广播onReceive的时间时，android.intent.action.TIME_SET会多次调用广播

3）当用户手动更改日期时，android.intent.action.DATE_CHANGED工作正常，但是这个动作也调用了android.intent.action.TIME_SET，因此广播onReceive调用了两次

在我的情况下，我想取消现有的闹钟并设置新闹钟，但现在它多次调用onReceive，结果取消现有闹钟并多次设置新闹钟＆amp;我收到多个通知

 <receiver android:name=".MyReceiver" android:enabled="true" android:exported="true">
<intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED" />
    <action android:name="android.intent.action.DATE_CHANGED" />
    <action android:name="android.intent.action.TIME_SET" />
</intent-filter>
</receiver>

MyReceiver.java

public class MyReceiver extends BroadcastReceiver {

    private String TAG="MyReceiver";

    private static final String ACTION_LOCAL_NOTIFICATION = "com.example.android.alarm.ACTION_LOCAL_NOTIFICATION";
    @Override
    public void onReceive(Context context, Intent intent) {

        if(ACTION_LOCAL_NOTIFICATION.equalsIgnoreCase(intent.getAction())) {

         Log.d("MyReceiver", "Send Local Notification");

        }else  if("android.intent.action.BOOT_COMPLETED".equalsIgnoreCase(intent.getAction()) ||
                "android.intent.action.TIME_SET".equalsIgnoreCase(intent.getAction()) ||
                "android.intent.action.DATE_CHANGED".equalsIgnoreCase(intent.getAction()))
        {

            Log.d("MyReceiver", "Cancel exhisting Alarm & Set new Alarm ");

            DBOperation databaseOperations=new DBOperation(context);
            databaseOperations.openSqliteDB();
            ArrayList<MyAlarmItem> alarmList=databaseOperations.fetchAllAlarm();
            databaseOperations.closeSqliteDB();
            int alarmListSize=alarmList.size();
            AppAlarmManager alarmManager=new AppAlarmManager(context);
            for (int i=0;i<alarmListSize;i++)
            {
                MyAlarmItem alarmItem=alarmList.get(i);
                alarmManager.RestoreAlarm(alarmItem);
            }
        }

}
