Adapter for the Spinner: Create Adapter class to render data into the spinner. Create class name CustomAdapter.java and extends it to ArrayAdapter(CustomItems).
Override two methods,

getView: return view of spinner with selected item position.
getDropDownView: return view of dropdown list of the spinner

here we have same view for both methods so we create new method customView and use it for both methods.
