Android中的Searchview正常运行，但单击时显示错误结果。

Question

所以我有一个带有searchview的自定义适配器。 每当我搜索特定的人时，我的搜索视图就会显示正确的结果。 但是，当我单击searchview中的项目时，它将返回原始列表的结果。

因此，例如，我有项目ab，cd，ef，并且我搜索ef。 searchview返回1项ef。 但是，如果单击它，我将获得ab的数据。

我该如何解决？ 还是我需要重写searchview的onclick方法？

谢谢。 （我将发布我的代码（我将删除不相关的代码），我的自定义适配器中包含searchview代码。另一个是包含我的searchview和listview列表的片段。

My Custom Adapater.

  public class OnCallFragment extends android.support.v4.app.Fragment implements SearchView.OnQueryTextListener{

    //Parsing the xml file and getting the data we need which is an arraylist of oncallContacts
    OnCallXMLParser b = new OnCallXMLParser();
    final ArrayList<OnCallContact> list = b.parse(getContext());

    //HEre the custom adapter is making the listviews
    adapter = new oncallAdapter(list, getContext());
    final ListView listView = (ListView) rootView.findViewById(R.id.onCallListView);

    SearchView search = (SearchView)rootView.findViewById(R.id.onCall_searchView);
    search.setOnQueryTextListener(this);

    //displaying the listview by setting the adapter.
    listView.setAdapter(adapter);
    listView.setFastScrollEnabled(true);

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            //The contact we are passing through. (Item that was clicked on)
            OnCallContact temp = list.get(position);

            Intent i = new Intent(getActivity(), OnCallDetail.class).putExtra("ContactInformation", temp);

            startActivity(i);

    });

    // Inflate the layout for this fragment
    return rootView;
}

@Override
public boolean onQueryTextChange(String newText) {
    adapter.getFilter().filter(newText);
    return false;
}

@Override
public boolean onQueryTextSubmit(String query) {
    return false;
}

}

谢谢！！

Answer 1

这很可能是因为结果ef在所有过滤结果中的位置以及结果ef在所有可用项目中的位置都不同。 您需要使用另一个变量，例如自定义标识符，而不是使用position。 有关更多信息，请参考此内容： 从列表视图中选择了错误的项目，并且列表视图 自定义过滤器在过滤时给出了错误的选择

Answer 2

对于遇到此问题的任何人，请确保您覆盖getcount，getitem。 GetItemId应该保持为返回0；否则，返回0。 其他2种方法必须覆盖它们。 希望对任何可能遇到此问题的人有所帮助。
