Where can i find the "more" button? Android

I am looking for the button that looks like (v).

Where can I find this android b开发者_StackOverflow中文版utton? thanks

That is ic_menu_more in R.drawable. To use programmatically:

myMenuItem.setIcon(android.R.drawable.ic_menu_more);

Here's a link to them all: http://since2006.com/android/2.1-drawables.php
