Question

I would like to create a actionbar, let it like gmail’s actionbar.
In other words,
When the item is selected in listView, actionbar’s logo will change to the Cancel button.
Does this have to custom actionbar’s layout?

or , it is not a actionbar ,it’s a Contextual Menus?

Answer 1

thanks @Selvin and @CommonsWare
it’s a context-menu, ListView or RecyclerView, and you can just call startActionMode() to start it (API 11 or later).

But in startActionMode(), it will not call onItemCheckedStateChanged,
you must implement a click listener from the adapter by yourself.
