java - Android Studio ExpandableList asking for text input -

i have developed weight conversion application works fine. when app launched, @ top of layout number box user must input value, example, 160lbs or 50kg, select conversion want perform expandable list gives options of pounds kilos or kilos pounds.

the issue when number box above expandable list , user clicks input value, keyboard comes , instead of tick @ bottom right, when clicked hides keyboard , value in place, instead goes normal keyboard.

this happens when expandable below number box. when list above number box works fine. user inputs value , clicks tick @ bottom right. want able place list below number box without prompt keyboard showing up.

code here if needed not sure if part of code @ all:
