Re: [tridroid] Hi, I am trying to set individual colors of text rows in a listView

Heh, I'm glad you enjoy it. Its frustating for me.  But, yes, I'll
take it off list.  FWIW,
	 public View getView(int position, View convertView, ViewGroup parent) {
         TextView text = new TextView(getContext(­));
         text.setText("Hi, I am position " + position);
         text.setTextColor(Co­lor.parseColor("#647­88e"));
         return  text;
	}

will indeed set the text and color. Thank god for you Fred. However,
it deletes my original text.  Got me how to fix it.
