推荐答案

此要点从戴维·史密斯显示了一种方法使用 ViewPager 有视觉效果非常类似于图库：

This gist from Dave Smith shows a way to use ViewPager to have visual results very similar to a Gallery:

引述我的博客文章上显示多个页面的主题在一时间 ViewPager ：

他的容器（ com.example.pagercontainer.PagerContainer ）会将 ViewPager 键，通话 setClipChildren（假）; 本身，所以尽管 ViewPager 专注于一个选定的页面上，有超越坐标其他页面的 ViewPager 界限仍清晰可见，只要他们在 PagerContainer 适合。通过定径 ViewPager 来比 PagerContainer 的 ViewPager 罐大小的页面，这种规模，留有余地其他页面待观察。 PagerContainer ，不过，需要帮忙，未免有触摸事件，如 ViewPager 将只处理刷卡事件自己可视范围，忽略可见双方的任何页面。

His container (com.example.pagercontainer.PagerContainer) wraps the ViewPager and calls setClipChildren(false); on itself, so even though the ViewPager is focused on one selected page, other pages that have coordinates beyond the ViewPager bounds are still visible, so long as they fit within the PagerContainer. By sizing the ViewPager to be smaller than the PagerContainer, the ViewPager can size its pages to that size, leaving room for other pages to be seen. PagerContainer, though, needs to help out a bit with touch events, as ViewPager will only handle swipe events on its own visible bounds, ignoring any pages visible to the sides.

您可能还需要筛选这个Android的开发者线程其中有人指出了一个问题，这在较新的Andr​​oid版本。你需要禁用硬件加速由于 ViewPager <错误/ code> 。

You might also want to sift through this android-developers thread, where somebody pointed out an issue with this on newer Android versions. You need to disable hardware acceleration due to a bug in ViewPager.
