应用框架 ViewPager Tab Fragment SlidingMenu

时间:2022-10-05 00:36:23

介绍
常见的应用框架
框架一:多个tab+Fragment,点击不同的tab加载不同的Fragment,不能滑动切换只能点击切换;
框架二:多个tab+ViewPager+FragmentPagerAdapter,点击不同的tab加载ViewPager对应的item,可以滑动切换,经过改进,可以实现"强制刷新"!
框架三:多个tab+ViewPager+FragmentPagerAdapter+SlidingMenu,左右滑菜单
其他:
上有标题栏,标题栏可以是在Fragment或ViewPager中的(如QQ,每个页面的标题栏都不一样)或者和tab同级(如微信,所有页面的标题栏都一样)。
