android - fragment android中的ListView

Question

如何获取List Item的位置？我只是想学习 fragment 。我在 developer.android.com 上看到了 ListFragment 的例子，但我很难理解。

所以我在 Fragment 中使用了 ListView 但是当我点击项目时我无法获得它的位置。我怎样才能得到它？

public class Fragment_listview extends Fragment implements AdapterView.OnItemClickListener {

    ListView listView;
    String[] days={"Sun","Mon","Tue"};
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment,container,false);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        listView= (ListView) getActivity().findViewById(R.id.listview);
        ArrayAdapter<String> adapter=new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,days);
        listView.setAdapter(adapter);
    }

    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

            Toast.makeText(getActivity(), "Position "+i, Toast.LENGTH_SHORT).show();


    }
}

您需要为您的ListView设置监听器

listView.setOnItemClickListener(this);
