android - 下拉刷新示例，Eclipse 找不到 setOnRefreshListener 命令

Question

我正在处理来自 Git-hub 的众所周知的下拉刷新示例

我加载了库并且一切正常，但是当我想调用方法 setOnRereshListener 时，Eclipse 找不到它。可能是什么问题？

这是例子中的代码:

        PullToRefreshListView pullToRefreshView = (PullToRefreshListView) findViewById(R.id.pull_to_refresh_listview);      
    pullToRefreshView.setOnRefreshListener(new OnRefreshListener<ListView>() {
        @Override
        public void onRefresh(PullToRefreshBase<ListView> refreshView) {
            // Do work to refresh the list here.
            new GetDataTask().execute();
        }
    });

这是我的代码:

public class MainActivity extends Activity {
private static final String URL = "http://192.168.1.103/php-android/testphp.php"; 
private static final String TAG_DATA = "data";
private static final String TAG_ID = "name";       
private static final String TAG_DATE = "date";      
public PullToRefreshListView listView;  
JSONArray data = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() .detectAll().penaltyLog().build(); 
    StrictMode.setThreadPolicy(policy);
    getDataInArray();

    PullToRefreshListView pullToRefreshView = (PullToRefreshListView) findViewById(R.id.pull_to_refresh_listview);      
    pullToRefreshView.setOnRefreshListener(new OnRefreshListener<ListView>() {
        @Override
        public void onRefresh(PullToRefreshBase<ListView> refreshView) {
            // Do work to refresh the list here.
            new GetDataTask().execute();
        }
    });     
}

不确定，但我相信这是由于方法签名 OnRefresh (PullToRefreshBase refreshView)，尝试删除 PullToRefreshBase refreshView，如下所示:

pullToRefreshView.setOnRefreshListener(new OnRefreshListener() {
        @Override
        public void onRefresh() {
            // Do work to refresh the list here.

            new GetDataTask().execute();
        }
    });

我在没有签名方法 OnRefresh () 的情况下使用了相同的结构，它工作正常。
