Question

On clicking a certain MenuItem in a Options Menu in Android, I need to change the title of a different MenuItem in the same Menu. What is the way to do this?

When a MenuItem in an options menu is clicked, onOptionsItemSelected(MenuItem menuitem) is called.
You can change the title of the MenuItem which is passed as a parameter in the
onOptionsItemSelected(MenuItem menuitem), but not of any other MenuItem. I need to know how to change the title of a MenuItem that is not passed as parameter to onOptionsItemSelected(), but which belongs to the same Menu.

I did not find a way to get handle to containing Menu inside the onOptionsItemSelected method (which is called when any MenuItem is clicked).

Many Thanks.

From the Android Dev Guide: http://developer.android.com/guide/topics/ui/menus.html

Changing the menu when it opens

The onCreateOptionsMenu() method is called only the first time the Options Menu is opened. The system keeps and re-uses the Menu you define in this method until your Activity is destroyed. If you want to change the Options Menu each time it opens, you must override the onPrepareOptionsMenu() method. This passes you the Menu object as it currently exists. This is useful if you’d like to remove, add, disable, or enable menu items depending on the current state of your application.

Note: You should never change items in the Options Menu based on the View currently in focus. When in touch mode (when the user is not using a trackball or d-pad), Views cannot take focus, so you should never use focus as the basis for modifying items in the Options Menu. If you want to provide menu items that are context-sensitive to a View, use a Context Menu.
