I seen some of the applications like gmail and other apps in which where there's an editText and textView while clicking on text long press i can see in the actionbar there's menu appear say cut, copy, select all ,share and lookup option appears.
This same behavior as a developer wanted to include in my application.
How can I achieve this?
