Answer 1

당신은 당신의 ExpandableListView에 리스너를 설정해야하고 그것에서 활동을 엽니 다

listView.setOnItemClickListener(new OnItemClickListener(onItemClick(AdapterView<?> parent, View view, int position, long id) { 
    // Launch the activity 
    Intent intent = new Intent(context, ActivityToOpen.class); 
    context.startActivity(intent); 
});
