这是我使用 chrisbanes pull 来刷新库的 XML 布局文件
出于某种原因，它只会显示可点击项目的可扩展列表中的第一个，当我点击它时它不会展开行，我一直在玩这个并且对为什么会发生这种情况感到困惑，这里是片段类的代码
public class TestExpandFragment extends ExpandableListFragment {
private String[] divideOptions = { "Test1", "Test2", "Test3", "Test4",
"Test5", "Test6", "Test7", "Test8" };
PullToRefreshScrollView mPullRefreshScrollView;
ScrollView mScrollView;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
try {
SimpleExpandableListAdapter expListAdapter = new SimpleExpandableListAdapter(
getActivity(), createGroupList(), // Creating group List.
R.layout.group_row, // Group item layout XML.
new String[] { "1" }, // the
// key
// of
// group
// item.
new int[] { R.id.row_name }, // ID of each group item.-Data
// under the key goes into
// this TextView.
createChildList(), // childData describes second-level
// entries.
R.layout.group_child_row, // Layout for sub-level
// entries(second
// level).
new String[] { "Sub Item" }, // Keys in childData maps to
// display.
new int[] { R.id.grp_child } // Data under the keys above go
// into these TextViews.
);
setListAdapter(expListAdapter); // setting the adapter in the list.
} catch (Exception e) {
System.out.println("Errrr +++ " + e.getMessage());
}
View view = inflater.inflate(R.layout.test_expandable_fragment, container,
false);

如果有人可以告诉我为什么会发生这种情况，因为它只会输出 Test1 但没有任何操作，刷新的拉动将在加载时出现，如果我取消拉动刷新，它确实有效，我已经使用过它以前用其他代码围绕其他类型的布局，并且从未遇到过这个，也许这很愚蠢，我不确定，但我想也许有人可以更快地看到问题。
