Fill spinner with array List

Question

I want to fill a spinner with the items of an array List but I can´t. Here is my code:

List<String> list = new ArrayList<String>();
list.add(id_circuito);

First, I add an element to the list and later:

ArrayAdapter<String> adp1=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,list);
adp1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp1.setAdapter(adp1);

It says me "The constructor ArrayAdapter(MainActivity.GetContacts, int, List) is undefined", how can I do this? Thanks

MainActivity.GetContacts is not a valid Context.

Change this

ArrayAdapter<String> adp1=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,list);

to

ArrayAdapter<String> adp1=new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,list);

OR

If its in a Fragment use getActivity(). Likely GeContacts (Fragment) is inside MainActivity

ArrayAdapter<String> adp1=new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,list);

the issue is related to the first argument this refers to MainActivity.GetContacts. You need a Context object. If you are inside a Fragment you can se getActivity(), NomeOfYourActvity.this otherwise
