Question

I am getting an error when trying to set my view to display the ListView for the file I want to display(text file). I am pretty sure it has something to do with

If you are getting that message when you are extending an ArrayAdapter, you are getting that error because you have not provided the correct resource id to display the item. Call the super class in the constructor and pass in the resource id of the TextView:

    //Pass in the resource id:  R.id.text_view
    SpinnerAdapter spinnerAddToListAdapter = new SpinnerAdapter(MyActivity.this,
            R.id.text_view,
            new ArrayList<>());

Adapter:

public class SpinnerAdapter extends ArrayAdapter {

    private Context context;
    private List values;

    public SpinnerAdapter(Context context, int textViewResourceId,
                          List values) {

        //Pass in the resource id:  R.id.text_view
        super(context, textViewResourceId, values);

        this.context = context;
        this.values = values;
    }
