intent.getExtra在将数据从活动传递到BroadcastReceiver时返回null

Question

    Intent intent=new Intent(this, AlarmReceiver.class);
    intent.putExtra("Test","Test Intent");
    PendingIntent pendingIntent=PendingIntent.getBroadcast(this,0,intent,0);
    alarmManager.set(AlarmManager.RTC_WAKEUP,System.currentTimeMillis()+2000,pendingIntent);

In BroadcastReceiver onReceive()

   String test=intent.getStringExtra("Test");

Intent.getExtra returns null while passing data from activity to BroadcastReceiver? Please help

这是正确的方法-指定一个标志！

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, uniqueRequestCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
