Android 片段中的拉刷新（Chris Banes插件）

我试图在片段中使用pull刷新，但不是list片段。 当pull to refresh的行是注释时，应用程序工作，但当我将它们带回来时，我得到以下错误：

这是我的片段：

public class FirstFragment extends Fragment implements OnClickListener {

private Button btnByText;
private Button btnByLocation;
private onSendToSecond listener;
SimpleCursorAdapter adapter;
LocationHelper helper;
public interface onSendToSecond{
    public void sendData(String data);      
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,         Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.first_fragment_layout, container, false);
    btnByText = (Button) view.findViewById(R.id.btnByText);
    btnByLocation = (Button) view.findViewById(R.id.btnByLocation);
    btnByText.setOnClickListener(this);
    btnByLocation.setOnClickListener(this);

    helper = new LocationHelper(getActivity(), "LocationDb.db", null, 1);
    Cursor c = helper.getLocation();

    String [] from = new String [] {helper.LOCATION_COL, helper.ADDRESS_COL, helper.DISTANCE_COL};
    int [] to = new int [] {R.id.txtLocation, R.id.txtAddress, R.id.txtDistance, R.id.imglocation};

    adapter = new SimpleCursorAdapter(getActivity(), R.layout.list_layout, c, from, to, 2);

    PullToRefreshListView list = (PullToRefreshListView) getView().findViewById(R.id.lstLocations);

    list.setAdapter(adapter);


});

    list.setAdapter(adapter);
    list.setOnRefreshListener(new OnRefreshListener<ListView>() {

        @Override
        public void onRefresh(PullToRefreshBase<ListView> refreshView) {            
            new Handler().postDelayed(new Runnable() {

        }
    });

    return view;
}

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);

    }

public类FirstFragment扩展了片段实现OnClickListener{
私人按钮btnByText；
专用按钮BTN定位；
私有的onSendToSecond侦听器；
SimpleCursorAdapter适配器；
位置助手；
公共接口onSendToSecond{
公共数据（字符串数据）；
}
@凌驾
CreateView上的公共视图（布局、充气机、视图组容器、捆绑包保存状态）{
视图=充气机。充气（R.layout.first\u fragment\u布局，容器，错误）；
btnByText=（按钮）view.findViewById（R.id.btnByText）；
btnByLocation=（按钮）view.findViewById（R.id.btnByLocation）；
btnByText.setOnClickListener（这个）；
setOnClickListener（this）；
helper=newlocationhelper（getActivity（），“LocationDb.db”，null，1）；
游标c=helper.getLocation（）；
字符串[]from=新字符串[]{helper.LOCATION\u COL，helper.ADDRESS\u COL，helper.DISTANCE\u COL}；
int[]to=newint[]{R.id.txtLocation，R.id.txtdaddress，R.id.txtdestance，R.id.imglocation}；
adapter=new SimpleCursorAdapter（getActivity（），R.layout.list_layout，c，from，to，2）；
PullToRefreshListView列表=（PullToRefreshListView）getView（）.findViewById（R.id.lstLocations）；
list.setAdapter（适配器）；
});
list.setAdapter（适配器）；
setOnRefreshListener（新的OnRefreshListener（）{
@凌驾
public void onRefresh（PullToRefreshBase refreshView）{
new Handler（）.postDelayed（new Runnable（））{
}
});
返回视图；
}
@凌驾
公共事务主任（活动）{
超级转速计（活动）；
}

更改

 PullToRefreshListView list = (PullToRefreshListView) getView().findViewById(R.id.lstLocations);

到

您刚刚漏掉了下面一行：-

ListView actualListView = mPullRefreshListView.getRefreshableView();

没有以上的线，你拉刷新不工作

有关更多信息，请参阅以下链接：-

也发布

first\u fragment\u layout.xml

文件除了您的错误：您可以使用基于Chris Banes abbadoned lib创建的文件。有一些修复和新功能，非常有用

ListView actualListView = mPullRefreshListView.getRefreshableView();
