我需要显示特定日期和时间的通知（2015年6月27日13:00）。最初，我正在显示吐司消息。我已经创建了一个广播接收器来做到这一点。我这样称呼待处理的意图-

I need to show a notification on a particular date and time (27-06-2015 13:00). Initially I am showing a toast message. I have created a broadcast receiver to do that. I am calling the pending intent like this -

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);

Broadcust接收方代码-

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

我正在尝试通过更改时间来检查我的电话。我将电话时间更改为12:59。但是，当我打电话给广播接收器时，按照我的逻辑，当时间为13:00时，它会立即显示吐司消息。我做错了什么吗？

I am trying to check that by changing the time of my phone.I am changing the phone time to 12:59. But When I am calling the Broadcast Receiver it instantly giving the toast message it should show when the time is 13:00 as per my logic. Am I doing anything wrong?

推荐答案

您的代码中的每件事看起来都很清楚，可能是 Calendar 您已初始化的obj。

Every thing looks clear in your code may be it is the problem of Calendar obj that you have initialized.

尝试如下操作，

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

并设置

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

希望这对您有所帮助。
