How to Create a menu for Android

 
//Call only once
@ Override
Public BooleanOncreateoptionsmenu (menu ){}
 

 


//The menu will be called before each display (applicable to creating a dynamic menu item. If it is a dynamic menu, remember to call it first.Menu. Clear ();Clear existing menu items)
@ Override
Public BooleanOnprepareoptionsmenu (menu ){}
 

//Called after the item is clicked
@ Override
Public BooleanOnmenuitemselected (IntFeatureid, menuitem item ){}
 

 


//Item is called after it is clicked (the execution efficiency is better than onmenuitemselected, and it is recommended to be used)
@ Override
Public BooleanOnoptionsitemselected (menuitem item ){}
 

 

You don't need to implement it all, depending on your needs.
