Question

我将AlarmManager和NotificationManager与BroadcastReceiver一起使用。当我设置具有特定日期的闹钟时，它是第一次工作。但是，当我修改日期并单击确认按钮时，警报可以在任何日期运行立即。我想设置过期日期后的警报间隔时间和固定时间。它有什么问题？我现在不明白。

confirmButton.setOnClickListener(new View.OnClickListener() 
{
    public void onClick(View v) {
    //set alarm with expiration date                
    am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    setOneTimeAlarm();
    Toast.makeText(fridgeDetails.this, "Alarm automatic set", 
        Toast.LENGTH_SHORT).show();
    setResult(RESULT_OK);
    finish();
}

public void setOneTimeAlarm() {
    c.set(Calendar.HOUR_OF_DAY, 14);
    c.set(Calendar.MINUTE, 49);
    c.set(expiredYear, expiredMonth, expiredDay);
    Intent myIntent = new Intent(fridgeDetails.this, AlarmService.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(
        fridgeDetails.this, 0, myIntent, PendingIntent.FLAG_ONE_SHOT);
    am.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(),
        AlarmManager.INTERVAL_DAY, pendingIntent);
}
});

AlarmService.java

public class AlarmService extends BroadcastReceiver{
    NotificationManager nm;
    @Override
    public void onReceive(Context context, Intent intent) {
        nm = (NotificationManager) context.getSystemService(
            Context.NOTIFICATION_SERVICE);
        CharSequence from = "Check your fridge";
        CharSequence message = "It's time to eat!";
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
            new Intent(), 0);
        Notification notif = new Notification(R.drawable.ic_launcher,
            "Keep Fridge", System.currentTimeMillis());
        notif.setLatestEventInfo(context, from, message, contentIntent);
        notif.defaults |= Notification.DEFAULT_SOUND; 
        notif.flags |= Notification.FLAG_AUTO_CANCEL; 
        nm.notify(1, notif);
    }   
}

您需要设置属性而不是FLAG_ONE_SHOT。这适用于单次报警事件，不适用于重复。试试这个

PendingIntent pendingIntent = PendingIntent.getBroadcast(
        fridgeDetails.this, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);

修改

正如您使用PendingIntent
进行通知一样
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,new Intent(), 0);

在这里你传递了Intent的空对象，你需要传递类名，当你点击通知哪个Activity会像你在警报设置时那样启动

Intent myIntent = new Intent(fridgeDetails.this, AlarmService.class); PendingIntent pendingIntent = PendingIntent.getBroadcast( fridgeDetails.this, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);

现在只需在意图中传递Acitivity名称，就像想要启动您的家庭活动和活动名称一样，如“homeactivity”

PendingIntent contentIntent = PendingIntent.getActivity(context, 0,new Intent(context,HomeActivity.class), 0);

当我更改日期时，通知会运行任何日期的Android闹钟
