wemall-mobile是基于WeMall的android app商城，只需要在原商城目录下上传接口文件即可完成服务端的配置，客户端可定制修改。本文分享 android开发Fragment中监听onKey事件主要代码，供技术员参考学习。 项目中越来越多的用到Fragment，下面记录一下在ActionBar中监听Fragment的onKey事件。 ActionBar实现Onkey事件，判断当前的fragment是哪一个，是不是所需要的Fragment,然后在需要监听OnKey事件的Fragment中写一个静态方法，传递keycode与event事件即可。 - package info.androidhive.tabsswipe;
