onReceive EVENT_REMINDER

Question

我已经创建了一个广播接收器来挂接日历EVENT_REMINDER并获取有关事件的信息

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    bReceiver = new HealtDroidBroadcastReceiver();
    IntentFilter inf = new IntentFilter("android.intent.action.EVENT_REMINDER");
    inf.addDataScheme("content");
    inf.addDataAuthority("com.android.calendar",null);
    registerReceiver(bReceiver,inf);
}

在Broadcastreceiver类中：

public void onReceive(Context context, Intent intent) { 
    Uri uri = intent.getData();
    String intentAction = intent.getAction();
    ContentResolver cr = context.getContentResolver();
    String sUri = uri.toString();
    Uri alertUri = Uri.parse(sUri);

    Cursor alertCursor = cr.query(alertUri, ALERT_PROJECTION,
            null /* selection */, null, null /* sort order */);

但我有一个错误，当cr.query：

附加的ID不是eventID，而是alarmTime。查看警报广播是如何创建的：scheduleAlarm()

您可以使用以下命令获取alarmTime：

String alarmTime = uri.getLastPathSegment();

然后，您可以使用以下代码来查询CalendarAlerts：

 String[] projection = new String[] {
          CalendarAlerts.EVENT_ID
  };

 String selection = CalendarContract.CalendarAlerts.ALARM_TIME + "=?";

 Cursor c = cr.query(CalendarContract.CalendarAlerts.CONTENT_URI_BY_INSTANCE, 
          projection, 
          selection, 
          new String[] {alarmTime},
          null);
