How to use a custom ArrayAdapter in a separate class?

Question

I have an inner class which extends ArrayAdapter in order to customize a ListView. I\'d like to break this inner class out into a separate file so other classes can use it

Answer 1

What about calling getLayoutInflater() on the context that is passed in.

LayoutInflater inflater = ((Activity)context).getLayoutInflater();

Answer 2

I will put the edits as comments:

public class myDynAdap extends ArrayAdapter<String>
{
    String [] list;
    Context mContext; //ADD THIS to keep a context

   public myDynAdap (Context context, int textViewResourceId, String [] objects)
   {
       super (context, textViewResourceId, objects);
       mCtx = context; // remove this line! I don't think you need it
       this.mContext = context;
       list = objects;
   }

    @Override
    public View getView (int position, View convertView, ViewGroup parent)
    {
        View row = convertView;

        if (row == null)
        {

            LayoutInflater inflater = ((Activity)mContext).getLayoutInflater ();  // we get a reference to the activity
            row = inflater.inflate (R.layout.main_listitem, parent, false);
        }

        TextView tv1 = (TextView) row.findViewById (R.id.tv_item);
        tv1.setBackgroundColor (Color.BLUE);

        // change background of 0th list element only
        if (position == 0)
            tv1.setBackgroundColor (Color.CYAN);

        return row;

    }
}
