Example analysis of menu usage in Android Development

This article describes the menu usage of Android development. Share with you for your reference, as follows:

Android phones use a key "menu" to display menus.

To realize the menu function, first create the menu through the method oncreateoptionmenu. There are two ways to create the menu: one is to directly import the XML file with menu, and the other is to add it directly with the method of menu class. After creating the menu, use the event listener onoptionitemselected to listen for events that can be triggered.

The following example has two activities. The above two methods are used to implement the menu. In each menu, there is an event listener to jump and exit the activity.

1. The menu file RES / menu / menu.xml under the resource file

Activity01.Java

Activity02.java

This example uses two activities. Don't forget to declare them in androidmanifest.xml.
