android - EditText inside ExpandableListView is not expanding the childs -

i have created expandablelistview following tutorial http://www.androidhive.info/2013/07/android-expandable-list-view-tutorial/ working fine. there have 2 textview in parent group. when adding edittext in parent group it's showing in listview after clicking on parent it's not expanding. assume it's due focus on edittext.

please find way focus on parent item clicking expands , shows child items. on other hand when try write in edittext should focus on without expanding listview.

here code:
