Question

我的应用程序正在运行，直到我点击我的expandablelist视图中的一个子元素。我不知道为什么因为一切看起来都很好。这是我的主要活动：

  expListView = (ExpandableListView) findViewById(R.id.lvExp);
    expListView2 = (ExpandableListView) findViewById(R.id.lvExp2);
    expListView3 = (ExpandableListView) findViewById(R.id.lvExp3);
    expListView4 = (ExpandableListView) findViewById(R.id.lvExp4);
    expListView5 = (ExpandableListView) findViewById(R.id.lvExp5);


    // preparing list data
    prepareListData();

    listAdapter = new ExpandableListAdapter(this, listDataHeader, listDataChild);
    listAdapter2 = new ExpandableListAdapter(this, listDataHeader2, listDataChild2);
    listAdapter3 = new ExpandableListAdapter(this, listDataHeader3, listDataChild3);
    listAdapter4 = new ExpandableListAdapter(this, listDataHeader4, listDataChild4);
    listAdapter5 = new ExpandableListAdapter(this, listDataHeader5, listDataChild5);



    // setting list adapter
    expListView.setAdapter(listAdapter);
    expListView2.setAdapter(listAdapter3);
    expListView3.setAdapter(listAdapter4);
    expListView4.setAdapter(listAdapter5);
    expListView5.setAdapter(listAdapter2);

    expListView5.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
        @Override
        public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
            if (groupPosition == 0) {

}
