Question

我试图让警报管理器触发，但事实并非如此，我无法理解。这是我在主要活动中的代码：

    public void scheduleAlarm() 
{       
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.set(Calendar.HOUR_OF_DAY, 11);
    calendar.set(Calendar.MINUTE, 32);
    Intent intentAlarm = new Intent(this, AlarmReceiver.class);

    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), PendingIntent.getBroadcast(this,1,  intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
}

这就是我班上的闹钟收发器：

public class AlarmReceiver extends BroadcastReceiver {
NotificationCompat.Builder mBuilder;
@Override
public void onReceive(Context context, Intent intent) {
    Toast.makeText(context, "You got pawned", Toast.LENGTH_LONG).show();
    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("My notification")
            .setContentText("Hello World!");

    // Sets an ID for the notification
    int mNotificationId = 001;
    // Gets an instance of the NotificationManager service
    NotificationManager mNotifyMgr = 
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    // Builds the notification and issues it.
    mNotifyMgr.notify(mNotificationId, mBuilder.build());
}

}

任何人都知道它为什么不起作用？

提前致谢！

所以不要忘记在android manifest中添加以下代码

<receiver android:name=".AlarmReceiver"/>

我的问题是这部分的错字......

报警管理器不会触发
