Android：从NotificationManager操作PendingIntent调用IntentService

我有一个推送通知应用程序.
当推送通知到来时,BroadcastReceiver会调用GCMIntentService来设置通知

mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Intent intent = new Intent(this, HomeActivity.class);
        Intent intent = new Intent(this, AddToCalendarIntentService.class);
        intent.putExtra(JSON_KEY_CLASS_ID, classid);
        intent.putExtra(JSON_KEY_CLASS_NAME, classname);
        intent.putExtra(Config.JSON_KEY_DATE, tgl);
        intent.putExtra(Config.JSON_KEY_TIME_START, timestart);
        intent.putExtra(Config.JSON_KEY_TIME_END, timeend);
        intent.putExtra(Config.JSON_KEY_VENUE, venue);
        Log.d(LOG_TAG, classid + ", " + classname + ", " + venue);
        PendingIntent contentIntent = PendingIntent.getService(this, 0,
                intent, 0);

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_notif)
                        .setContentTitle("Re: " + classname)
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText(pesan))
                        .setContentText(pesan)
                        .setDefaults(NotificationCompat.DEFAULT_VIBRATE)
                        .setDefaults(NotificationCompat.DEFAULT_LIGHTS)
                        .setDefaults(NotificationCompat.DEFAULT_SOUND)
                        .addAction(R.drawable.ic_action_add_person, "Add to Calendar", contentIntent)
                        .setAutoCancel(true)
                        .setTicker("Reschedule Class");

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

当用户单击“添加到日历”时,它将调用PendingIntent以使用所有参数启动AddToCalendarIntentService.

public class AddToCalendarIntentService extends IntentService {

public AddToCalendarIntentService() {
    super("AddToCalendarIntentService");
}

@Override
protected void onHandleIntent(Intent intent) {
    final String JSON_KEY_CLASS_NAME = "classname";
    final String JSON_KEY_CLASS_ID = "classid";
    Bundle extra = intent.getExtras();
    String title = extra.getString(JSON_KEY_CLASS_NAME);
    String location = extra.getString(Config.JSON_KEY_VENUE);
    String tgl = extra.getString(Config.JSON_KEY_DATE);
    String[] tglSplit = tgl.split("-");
    int year = Integer.parseInt(tglSplit[0]);
    int month = Integer.parseInt(tglSplit[1]);
    int date = Integer.parseInt(tglSplit[2]);

    String timestart = extra.getString(Config.JSON_KEY_TIME_START);
    String timeend = extra.getString(Config.JSON_KEY_TIME_END);
    String[] start = timestart.split(":");
    String[] end = timeend.split(":");
    int hourStart = Integer.parseInt(start[0]);
    int minStart = Integer.parseInt(start[1]);
    int hourEnd = Integer.parseInt(end[0]);
    int minEnd = Integer.parseInt(end[1]);
    Log.d("INTENT SERVICE", location);
    TaskHelper.addToCalendar(this, "Reschedule: " + title, location, year, month-1, date, hourStart, minStart, hourEnd, minEnd);
    NotificationManager mNotification = (NotificationManager) this
            .getSystemService(Context.NOTIFICATION_SERVICE);
    mNotification.cancel(1);
}
}

该代码有效,但是如果我再次收到另一个通知,并将其添加到日历中,则AddToCalendarIntentService中的参数将保留旧参数,而忽略新参数.
例如,在第一个位置是印度尼西亚,GCMIntentService和AddToCalendarIntentService日志都显示印度尼西亚.

在第二个通知中,位置是新加坡,它在GCMIntentService中正确显示,但是在登录AddToCalendarIntentService时,它显示印度尼西亚(应该是新加坡).

请帮忙.

谢谢.

解决方法:

这是因为系统认为它是相同的PendingIntent,所以如果要具有两个挂起的Intent,则需要对其进行区分.

最简单的方法是提供不同的requestCodes(PendingIntent.getService的第二个参数).
