How to use a custom ArrayAdapter in a separate class?

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 but having some trouble with getLayoutInflater().

Basically, my getView() method doesn't know what getLayoutInflater() is, even though I'm extending ArrayAdapter. Anyone know how to get this working correctly?

Thanks!

public class myDynAdap extends ArrayAdapter<String>
{
    String [] list;


   public myDynAdap (Context context, int textViewResourceId, String [] objects)
   {
       super (context, textViewResourceId, objects);
       mCtx = context;
       list = objects;
   }

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

        if (row == null)
        {

            LayoutInflater inflater = getLayoutInflater ();  // <--- "The method getLayoutInflater() is undefined for the type myDynAdap"
            row = inflater.inflate (R.layout.main_listitem, parent, false);
        }

        TextView tv1 = (TextView) row.findVi开发者_开发知识库ewById (R.id.tv_item);
        tv1.setBackgroundColor (Color.BLUE);

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

        return row;

    }
}

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

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

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;

    }
}
