- resId
- Resource ID of a drawable to use for the up indicator, or null to use the theme's default
Set an alternate drawable to display next to the icon/logo/title when ActionBar.DISPLAY_HOME_AS_UP is enabled. This can be useful if you are using this mode to display an alternate selection for up navigation, such as a sliding drawer.
If you pass 0 to this method, the default drawable from the theme will be used.
If you implement alternate or intermediate behavior around Up, you should also call ActionBar.SetHomeActionContentDescription(int) to provide a correct description of the action for accessibility support.
