Hi There,

As you know, we create a menuitem at onCreateOptionsMenu method,

However, when the view content has been changed, for example,

first the Screen is blank, no view is added,and we display only one
menuitem called "Add a Button",
After fullfill this function, I want to add a menuitem "Delete a
Button" when A button-view added to screen and focus is on.

so when the user click menu, it will show Add a Button,Delete aButton.

How to implement this function, which method should we override it?

Thanks~~
