我正在尝试制作应用程序，我正在制作服务器请求并获得响应，而我正在收到回复，即使应用程序被杀，我也会显示通知。所以这就是为什么我把所有这些都用在服务中并且在得到响应之后我从服务器响应中获得广播信息到广播接收器活动中显示在应用程序中显示的recyclerview.info中的信息（没有点击通知但是连续的网络请求和响应）因为我做直接广播，但我点击通知没有显示在recyclerview。怎么解决这个..
NotificationActivity：

我试图遵循Stack Overflow的解决方案，但我无法解决它。任何帮助将不胜感激！

仅当您当前的活动位于前景或可见时才会调用FYI onReceive()。对于点击通知执行任务，当您的活动/应用程序处于后台时，您也应该在onCreate()中执行与onReceive()中相同的操作：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notification);
Intent notificationIntent = getIntent.getStringExtra("Result");
if(notificationIntent != null){
//do whatever you have done in onReceive().
}
}
