片段中的可扩展ListView

Question

我有一个工作的expandablelistview代码,它作为一个独立的工作正常.我有另一个用于滑动标签视图的工作代码,我单独编写.

这些都是在通过一些博客,android开发和stackoverflow问题后编写的.

当我尝试将可扩展的listview组合并放入其中一个片段时,我最终得到一个错误,我无法解决.

这是Fragment片段中的代码:

public class Fragment1 extends Fragment {
private static final String NAME = "NAME";
private static final String IS_EVEN = "IS_EVEN";

private ExpandableListAdapter mAdapter;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    List<Map<String, String>> groupData = new ArrayList<Map<String, String>>();
    List<List<Map<String, String>>> childData = new ArrayList<List<Map<String, String>>>();
    for (int i = 0; i < 10; i++) {
        Map<String, String> curGroupMap = new HashMap<String, String>();
        groupData.add(curGroupMap);
        curGroupMap.put(NAME, "Group " + i);
        curGroupMap.put(IS_EVEN, (i % 2 == 0) ? "This group is even" : "This group is odd");

        List<Map<String, String>> children = new ArrayList<Map<String, String>>();
        for (int j = 0; j < 2; j++) {
            Map<String, String> curChildMap = new HashMap<String, String>();
            children.add(curChildMap);
            curChildMap.put(NAME, "Child " + j);
            curChildMap.put(IS_EVEN, (j % 2 == 0) ? "This child is even" : "This child is odd");
        }
        childData.add(children);
    }

    // Set up our adapter
    mAdapter = new SimpleExpandableListAdapter(
            getActivity(),
            groupData,
            android.R.layout.simple_expandable_list_item_1,
            new String[] { NAME, IS_EVEN },
            new int[] { android.R.id.text1, android.R.id.text2 },
            childData,
            android.R.layout.simple_expandable_list_item_2,
            new String[] { NAME, IS_EVEN },
            new int[] { android.R.id.text1, android.R.id.text2 }
            );
    setListAdapter(mAdapter);
}

}`

我不断在最后一行得到错误:'方法setListAdapter(ExpandableListAdapter)未定义为Fragment1'类型.

其余代码显示没有错误.

请帮忙.我该如何纠正这个问题.

我自己能够解决问题.为了将来参考,这里是代码.可能很乱,需要清理,但它现在有效!

  public class HotDeals extends Fragment {
private ExpandableListAdapter mAdapter;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,                   Bundle              savedInstanceState) {
    View v = inflater.inflate(R.layout.saved_tabs, null);

return v;
}

private static final String NAME = "NAME";
private static final String IS_EVEN = "IS_EVEN";

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    List<Map<String, String>> groupData = new ArrayList<Map<String, String>>();
    List<List<Map<String, String>>> childData = new ArrayList<List<Map<String, String>>>();
    for (int i = 0; i < 10; i++) {
        Map<String, String> curGroupMap = new HashMap<String, String>();
        groupData.add(curGroupMap);
        curGroupMap.put(NAME, "Group " + i);
        curGroupMap.put(IS_EVEN, (i % 2 == 0) ? "This group is even" : "This group is odd");

        List<Map<String, String>> children = new ArrayList<Map<String, String>>();
        for (int j = 0; j < 2; j++) {
            Map<String, String> curChildMap = new HashMap<String, String>();
            children.add(curChildMap);
            curChildMap.put(NAME, "Child " + j);
            curChildMap.put(IS_EVEN, (j % 2 == 0) ? "This child is even" : "This          child     is odd");
        }
        childData.add(children);
    }
    ExpandableListView lv = (ExpandableListView) getActivity().findViewById(R.id.list);
    // Set up our adapter
    mAdapter = new SimpleExpandableListAdapter(
            getActivity(),
            groupData,
            android.R.layout.simple_expandable_list_item_1,
            new String[] { NAME, IS_EVEN },
            new int[] { android.R.id.text1, android.R.id.text2 },
            childData,
            android.R.layout.simple_expandable_list_item_2,
            new String[] { NAME, IS_EVEN },
            new int[] { android.R.id.text1, android.R.id.text2 }
            );
    lv.setAdapter(mAdapter);
}
}
