Android 导航抽屉和碎片

我有我的导航抽屉，它很好用。现在我创建了片段：

public class LabourFragment extends Fragment {
    private ListView listViewLabour;
    private String[] resourcesList;


    public LabourFragment() {
        // Required empty public constructor
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        //set adapter
        //TODO: change later to proper resource pull from server

        //have to use getActivity() as this is fragment and findViewById works from activity only

        ListView listView = (ListView) getActivity().findViewById(R.id.drawerList);
        listView.setAdapter(new ArrayAdapter(getActivity(), android.R.layout.simple_list_item_1, resourcesList));
    }


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

        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_labour, container, false);

    }


}

现在我从主活动调用片段：

public void selectItem(int position) {
    listView.setItemChecked(position, true);
    setTitle(getResources().getTextArray(R.array.drawerMenuList)[position]);

    FragmentManager fragmentManager = getFragmentManager();
    //TODO: open proper acvtivity
    switch (position){ //positions reflects menu in drawer
        case 0:
            LabourFragment fragment = new LabourFragment();
            fragmentManager.beginTransaction()
                    .replace(R.id.mainContentFragment, fragment)
                    .commit();
            break;


    }

并获取错误消息：

错误：100，25错误：找不到适用于replaceint，LabourFragment的方法 方法FragmentTransaction.replaceint，Fragment不适用 无法通过方法调用转换将实际参数LabourFragment转换为片段

试图将LabourFragment抛成碎片，但运气不佳。 我做错了什么？

谢谢。

您的活动扩展了什么？您的碎片导入了什么？您似乎正在使用支持库中的碎片和原始源代码中的碎片。谢谢。现在很明显。
