PendingIntent 获取请求代码 [英] PendingIntent get requestCode

问题描述

我使用 AlarmManager 来启动服务.当我设置 AlarmManager 时，我使用 PendingIntent 并使用一个唯一的 requestCode，它等于我数据库中的 id 行.

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); 

我如何在服务启动时检索该 ID?我基本上只需要 requestCode 参数.我想使用该 ID 从我的数据库中检索数据并将其显示在通知中.我已经实现了所有的东西，我只需要那个 requestCode.能拿到吗?

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?

谢谢

推荐答案

您需要将 lecture.getId() 放入您的 myIntent 的 extras 中.根据 Javadoc requestCode 甚至还没有使用.

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);
