How to make an ExpandableListView in Android always show child items

Question

I want to make an ExpandableListView which should always be showing its children elements even after clicking the header, and it should not collapse. How could I implement this concept?

Why are you using `ExpandableListView` in this case? Just use a regular `ListView`, with different row layouts for the "children" to suggest that they are children (e.g., contents indented). — CommonsWare, Jul 15 '14 at 11:57
and in oncreatelistView.setOnGroupCollapseListener(new OnGroupCollapseListener() { @Override public void onGroupCollapse(int groupPosition) { // TODO Auto-generated method stub listView.expandGroup(groupPosition); } }); — Abhimanyu, Jul 15 '14 at 12:48

you can expand all groups one by one as below as mentioned in this post

ExpandableListView explst;

explst.expandGroup(0);
explst.expandGroup(1);

for disabling collapse you can define a OnGroupClickListener which returns true, like so: (as mentioned in this post)

explst.setOnGroupClickListener(new OnGroupClickListener() {
  @Override
  public boolean onGroupClick(ExpandableListView parent, View v,
                              int groupPosition, long id) { 
    return true; // This way the expander cannot be collapsed
  }
});
