Question

所以标题非常缺乏信息，因为这个问题很难描述。基本上，我有一系列的Alarm对象，每个都有id，时间，名称等。当我为AlarmManager创建PendingIntent时，我用PendingIntent标记了它与之关联的警报的id，所以我可以删除警报稍后（如果用户决定删除它）。但是当闹钟响起时，我有一个AlarmReceiver.java的课程WakefulBroadcastReceiver和一个方法onReceive(final Context context, Intent intent)

package org.rtsd.morningtalk;

import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.support.v4.content.WakefulBroadcastReceiver;
import android.widget.Toast;

/**

 */
public class AlarmReceiver extends WakefulBroadcastReceiver {

    @Override
    public void onReceive(final Context context, Intent intent){
        //Call the Text-to-Speech software
        //Perform any actions necessary
        Toast.makeText(context,
                "BEEP!",
                Toast.LENGTH_SHORT).show();

    }
}

我在这里使用AlarmManager创建警报通知

            if (!alarmExists(alarm)) {
                pendingIntent = PendingIntent.getBroadcast(MainActivity.this, alarm.getId(), intent, 0);
                if (alarm.isDaily() || alarm.isWeekly()) {
                    dbHandler.createAlarm(alarm);
                    Alarms.add(alarm);
                    alarmAdapter.notifyDataSetChanged();
                    if (alarm.isDaily())
                        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, AlarmOrganizerTools.getAlarmTime(alarm), TimeUnit.DAYS.toMillis(1), pendingIntent);
                    else if (alarm.isWeekly())
                        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, AlarmOrganizerTools.getAlarmTime(alarm), TimeUnit.DAYS.toMillis(7), pendingIntent);

                    updateNextAlarm();
                }
                else {
                    alarmManager.set(AlarmManager.RTC_WAKEUP, AlarmOrganizerTools.getAlarmTime(alarm), pendingIntent);
                }
                Toast.makeText(getApplicationContext(),
                        "Your Alarm has been created!",
                        Toast.LENGTH_SHORT).show();
                resetAlarmCreator();

                updateNextAlarm();
            }

我的问题是当闹钟响起并且调用onReceive时，我不知道如何将该警报与我的一个警报对象相关联，以便我可以从中提取信息。任何帮助，将不胜感激。感谢

您不需要ENTIRE警报对象来获取某些信息......

长答案简短：放好并获得额外的

if (!alarmExists(alarm)) 
{
    intent.putExtra("someKey", "some information here");
    pendingIntent = PendingIntent.getBroadcast(MainActivity.this, alarm.getId(), intent, 0);
    if (alarm.isDaily() || alarm.isWeekly()) {
        dbHandler.createAlarm(alarm);
        Alarms.add(alarm);
        // rest of code here....

稍后......处理onReceive

时

@Override
public void onReceive(final Context context, Intent intent){
    String tada = intent.getStringExtra("someKey");
    // do something with that information
    Toast.makeText(context,
            "BEEP!",
            Toast.LENGTH_SHORT).show();

}

如何将（AlarmManager）通知与其关联的对象相关联？
