Overwrite MENU key to create custom menu
When user click on the hardware MENU key, Android OS will pop-up option menu; refer to the post "Create OptionsMenu in /res/menu/menu.xml" to know how to implement a formal OptionMenu. Alternatively, we can overwrite the default menu to create our custom menu as shown below:
Create /res/layout/menu.xml to make the layout of our manu. You can replace the android:src items for your own icon.
