有没有办法以编程方式更改操作栏菜单项的文本并实时更新？

Question

So I have a fragment activity and swipe-able views and what not. So right now I just want to know... lets say if the user clicks on any of the items in the list then the menu item in the action bar will add 1.

In my action bar I have the item: "Count: " and another blank item that will store the amount of times a user clicks on an item (ID is countHolder)

So is there a way to have that countHolder update everytime the user clicks on an item and do it in real time?

Also how would it be achieveable? I know it would have to be in my onClickListener but I dont know how I would pass that variable around.

Answer 1

从点击事件中，您可以尝试：

getActionBar().setTitle("Count: " + countHolder);
