Android 显示特定日期和时间的通知

我需要在特定日期和时间（27-06-2015 13:00）显示通知。起初，我会向大家展示祝酒词。我已经创建了一个广播接收器来实现这一点。我这样称呼未决的意图-

活动代码-

Calendar cal=Calendar.getInstance();
cal.set(Calendar.MONTH,(5));
cal.set(Calendar.YEAR,2015);
cal.set(Calendar.DAY_OF_MONTH, 27);
cal.set(Calendar.HOUR_OF_DAY,13);
cal.set(Calendar.MINUTE,00);

Intent myIntent1 = new Intent(this, AlarmBroadCustReciver.class);
PendingIntent pendingIntent1 = PendingIntent.getBroadcast(this, 1253, myIntent1,
        PendingIntent.FLAG_UPDATE_CURRENT);

AlarmManager alarmManager1 = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager1.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent1);

public class AlarmBroadCustReciver extends BroadcastReceiver {
    public AlarmBroadCustReciver() {
    }

    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();
    }
}

Broadcust接收器代码-

Calendar cal=Calendar.getInstance();
cal.set(Calendar.MONTH,(5));
cal.set(Calendar.YEAR,2015);
cal.set(Calendar.DAY_OF_MONTH, 27);
cal.set(Calendar.HOUR_OF_DAY,13);
cal.set(Calendar.MINUTE,00);

Intent myIntent1 = new Intent(this, AlarmBroadCustReciver.class);
PendingIntent pendingIntent1 = PendingIntent.getBroadcast(this, 1253, myIntent1,
        PendingIntent.FLAG_UPDATE_CURRENT);

AlarmManager alarmManager1 = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager1.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent1);

public class AlarmBroadCustReciver extends BroadcastReceiver {
    public AlarmBroadCustReciver() {
    }

    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();
    }
}

我正试图通过更改手机的时间来检查这一点。我正在将手机时间更改为12:59。但当我打电话给广播接收器时，它会立即发出祝酒词，按照我的逻辑，它应该在13:00时显示。我做错了什么吗？

代码中的每一件事情看起来都很清楚，可能是您初始化的

Calendar

obj的问题

一次尝试如下：

Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
cal.clear();
cal.set(2015,5,27,13,00); 

以及设置

alarmManager1.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent1);

希望这能对你有所帮助。

是的，你完全正确@Nag。投你一票；-）
