更新:来自@Ovidiu-这是我将putExtra推送的代码

Update: from @Ovidiu - here is my code to putExtra to push

       Notification notification = new Notification(icon, tickerText, System.currentTimeMillis());
       notification.contentView = contentView;

       Intent notificationIntent = new Intent(this, Startup.class);
       notificationIntent.putExtra("JOBID", jobId);

       PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_ONE_SHOT);

       notification.flags = Notification.FLAG_AUTO_CANCEL;
       notification.contentIntent = contentIntent;


       mNotificationManager.notify(jobId, notification);

，在主活动中，"Startup.java"代码为

and on Main Activity "Startup.java" code is

    Intent intent = this.getIntent();
    if (intent != null && intent.getExtras() != null && intent.getExtras().containsKey("JOBID")) {
        int jobID = this.getIntent().getExtras().getInt("JOBID");

        if (jobID > 0) {

        }
    }

intent.getExtras()始终返回null.原来，我需要传递PendingIntent.FLAG_ONE_SHOT.现在就过去了！！

intent.getExtras() always return null. Turn out, I need to pass PendingIntent.FLAG_ONE_SHOT . It is now passed along!!

推荐答案

创建Intent来启动应用程序时需要使用putExtra(ID_KEY,id)，并且在onCreate()方法中可以使用getIntent().getExtras().getInt(ID_KEY);检索您传递的ID integer.

You need to use putExtra(ID_KEY,id) when you create your Intent for starting your application, and in your onCreate() method you can use getIntent().getExtras().getInt(ID_KEY); to retrieve your passed id integer.
