的PendingIntent get请求code [英] PendingIntent get requestCode

问题描述

我使用 AlarmManager 来启动服务。当我设置了 AlarmManager 我用的PendingIntent 并使用独特的请求code等于一个ID行中我的数据库。

I use an AlarmManager to start a service. When i set up the AlarmManager i use the PendingIntent and use a unique requestCode which is equal to a id row in my database.

PendingIntent pendingIntent = PendingIntent.getBroadcast(SettingsActivity.this,
                            lecture.getId(), myIntent, 0); 

我怎样才能找回我的服务，该ID在启动时？我基本上只需要请求code参数。我想使用该ID从我的数据库中检索数据并显示在一个通知。我已经实现了所有的东西，我只需要这一请求code。是否有可能得到它？

How can I retrieve that id in my service when it starts? I basically need only the requestCode parameter. I want to use that id to retrieve data from my database and show it in a notification. I have implemented all the stuff, I just need that requestCode. Is it possible to get it?

推荐答案

您需要把 lecture.getId（）到 myIntent的临时演员。据的Javadoc <一个href=\"http://developer.android.com/reference/android/app/PendingIntent.html#getBroadcast%28android.content.Context,%20int,%20android.content.Intent,%20int%29\">request$c$c甚至没有用呢。

You need to put lecture.getId() into extras of your myIntent. According to Javadoc requestCode is not even used yet.

// store id
myIntent.putExtra("id", lecture.getId());

// read id or -1, if there is no such extra in intent
int id = myIntent.getIntExtra("id", -1);
