Question

我创建了一个可扩展列表，但是当我点击父级但它没有打开子组件并且它关闭它时。我不知道发生了什么错误。如果有人说我也提供快照。我尝试了很多东西但没有发生任何事情。我发生了所有这些事情bcoz添加滚动视图之前添加滚动视图这些工作完美。但不是它不工作检查我的xml文件，如果发现任何错误，请通知我。

我的MainActivity.java： -

  ExpandableListAdapter listAdapter;
ExpandableListView expListView;
List<String> listDataHeader = new ArrayList<String>();
HashMap<String, List<String>> listDataChild =  new HashMap<String, List<String>>();;
List<String> innerhref = new ArrayList<>();
 //   private List<String> firstLevelSubMenus = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayShowHomeEnabled(true);

    // get the listview
    expListView = (ExpandableListView) findViewById(R.id.lvExp);

    // preparing list data
   // prepareListData();

    listAdapter = new ExpandableListAdapter(this, listDataHeader, listDataChild);

    // setting list adapter
    expListView.setAdapter(listAdapter);

    textView = (TextView)findViewById(R.id.discount_and_offers);
