I want to dynamic change dialog's list item's textcolor. But list.getChildAt() confused me very much! Can you help me?
<p>I got that it seems the list.getchildAt() method return not null only when the list has shown once. If the list has not shown before, I call List.getChildAt() will return null. How can I do it, I want before the dialog's list shown before to change the list item's textcolor?</p>
