我需要在特定日期和时间(27-06-2015 13:00)显示通知。最初我正在展示祝酒词。我已经创建了一个广播接收器来做到这一点。我正在调用这样的未决意图 -
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);
Broadcust Receiver Code -
public class AlarmBroadCustReciver extends BroadcastReceiver {
public AlarmBroadCustReciver() {
}
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();
}
}
我试图通过更改手机的时间来检查。我正在将手机时间更改为12:59。但是当我呼叫广播接收器时,它立即发出吐司消息,它应该按照我的逻辑时间13:00显示。我做错了吗?
答案 0 :(得分:2)
在您的代码中看起来很清楚,可能是您初始化Calendar
obj的问题。
尝试如下,
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);
希望这会对你有所帮助。
