ExpandableListView Group View Expand Default
Now I got solution and it will work perfectly.. Please use this..
ExpandableListView Exlist;
Exlist.expandGroup(0);
Exlist.expandGroup(1);
I built this snippet based off Nikhil's answer. Thought others might find it useful as well. Only works if you are using BaseExpandableListAdapter. elv
ExpandableListView elv = (ExpandableListView) findViewById(R.id.elv_main);
elv.setAdapter(adapter);
for(int i=0; i < adapter.getGroupCount(); i++)
elv.expandGroup(i);
Perfect solution for expanding expandable listview
ExpandableListAdapter expandableListAdapter;
ExpandableListView expandableListView;
expandableListView.expandGroup(0);
expandableListView.expandGroup(1);
expandableListAdapter.notifyDataSetChanged();
This is a perfect solution, it will increase automatically
ExpandableListView elv = (ExpandableListView) findViewById(R.id.elv_main);
elv.setAdapter(adapter);
for(int i=0; i < adapter.getGroupCount(); i++)
elv.expandGroup(i);
but this is based on the item positions
ExpandableListView Exlist;
Exlist.expandGroup(0);// first item of listview
Exlist.expandGroup(1);//second item of listview
