How can I make the spinner width same as largest available item width

Question

I realize even I use wrap_content for my spinner (I avoid using match_parent as I do not want the spinner overly long), and using match_parent

Answer 1

Put your TextView inside LineanLayout in Spinner Item XML,

And Pass your TextView's id to custom adapter constructor

CustomAdapter adapter = new CustomAdapter(this,R.layout.spinner_item,R.id.text_view_0,arraylist);

Constructor

  public CustomAdapter(Context context, int resource, int textViewId, ArrayList resultList) {
                super(context, resource, textViewId, resultList);
        ...
        ...
            }
