只是想知道是否有人可以帮助我这个,我想添加一个刷卡刷新功能,我不能看到我要去哪里错了,我只是得到错误信息无法解析符号mySwipeRefreshLayoutAndroid工作室刷卡刷新

继承人的代码。由于

public class eventsListActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener { 

mySwipeRefreshLayout.setOnRefreshListener(
     new SwipeRefreshLayout.OnRefreshListener() { 
    @Override 
    public void onRefresh() { 

     refreshList(); 
    } 
} 

public class eventsListActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener { 

mySwipeRefreshLayout.setOnRefreshListener(
     new SwipeRefreshLayout.OnRefreshListener() { 
    @Override 
    public void onRefresh() { 

     refreshList(); 
    } 
}

我编辑了您的文章,它将会显示一会儿。我在你的文章中发布了代码。确保你对代码进行了更好的解释并发布你的logcat,并且你可以删除指向某个webiste外部的stackoverflow的链接。 – Yupi

您需要在使用Java之前声明一个变量。您的'mySwipeRefreshLayout'尚未在当前类或任何超类中声明。在尝试Android之前,请花一些时间在[Java Tutorials](https://docs.oracle.com/javase/tutorial/)上工作,否则从现在起,您将遇到各种难题。 –

您不需要使用SwipeRefreshLayout.OnRefreshListener实现。

而我还没有发现另一个问题。也许在refreshList()中有错误;方法
