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

// Listview Group click listener
expListView.setOnGroupClickListener(new OnGroupClickListener() {

@Override
public boolean onGroupClick(ExpandableListView parent, View v,
int groupPosition, long id) {
// Toast.makeText(getApplicationContext(),

int groupPosition, int childPosition, long id) {

list_group остается такой же, как и ссылка < /p>

В этом списке дочерних людей есть только текстовый обзор. Я хочу добавить ImageView и TextView в список детей. Я могу добавить это, изменив List_item.xml, чтобы сдержать представления. Как я могу добавить данные в этот представление ребенка, в котором есть несколько представлений?
