About android:displayOptions

Question

Please, explain to me the meaning of all options available in android:displayOptions such as :

-useLogo
-showHome
-homeAsUp
-showTitle
-showCustom -disableHome

I've read Doc for Constant displayOptions but I still can't understand that

Answer 1

useLogo:

Use logo instead of icon if available. This flag will cause appropriate navigation modes to use a wider logo in place of the standard icon.

showHome:

Show 'home' elements (logo and icon) in this action bar, leaving more space for other navigation elements.

homeAsUp:

Display the 'home' element such that it appears as an 'up' affordance. e.g. show an arrow to the left indicating the action that will be taken. Set this flag if selecting the 'home' button in the action bar to return up by a single level in your UI rather than back to the top level or front page. Remember, that you can declare the logical parent of each activity by specifying the android:parentActivityName attribute in the element.

showTitle:

Show the activity title and subtitle, if present.

showCustom:

Show the custom view if one has been set.

disableHome:

haven't found this one, but there's a function setHomeButtonEnabled(boolean) in ActionBar class which can help to enable or disable home button.

All these can be found at ActionBar reference.
