    In the below example code I have created change location page. Here I have first created select_location.xml layout. In select_location layout I have added ScollView , TextView and imageView and In Selectlocation.Activity I have intializeUI value and I have used api code from backend server for fetching value data and I have also used onClicklistner method. See the below code it will clerly describe you how to make change locationpage.

    Step(1)created select_location.xml layout
