[android help] Pull to refresh example, Eclipse don't find setOnRefreshListener command

iam dealing with well known pull to refresh example from Git-hub

I loaded library and everything is working as it should but when i want to call method setOnRereshListener, Eclipse don't find it. What could be a problem?

This is code from example:

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

And this is my code:

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() {
        @Override
        public void onRefresh(PullToRefreshBase refreshView) {
            // Do work to refresh the list here.
            new GetDataTask().execute();
        }
    });     
}
