I have solved my problem by only changing the array which is to be set as adapter inside view
listAdapter = new ExpandableListAdapter(MainActivity.this, listDataHeader1, listDataChild1);
// setting list adapter
expListView.setAdapter(listAdapter);
This is what i have written when we click on any item on left Drawer inside clicklistener. I want to change the items of navigation drawer by clicking of any item inside it. But on clicking of back button the previous item get loaded which must not close the drawer that's what i want
