viewpage_fragment
Viewpage_Fragment 很不错的android多页面滑动效果实例，完整的Java源代码，创建时间：2013-8-2 下午4:56:15 ，基于android.support.v4.app.Fragment实现 让页面list，页面title list，滑动显示，在代码中定义适配器，得到每个页面，每个页面的title，得到页面的总个数，根据这些信息实现多页面的滑动。(Viewpage_Fragment very good android multi-page sliding effect instance, a complete Java source code, creation time :2013-8-2 4:56:15 pm based android.support.v4.app.Fragment achieve make the page list, the page title list, slide shows, adapters defined in the code, to get each page, each page s title, to get the total number of pages, according to the information page of multi-slide.)
