android - 如何从 Gallery 迁移到 Horizo​​ntalScrollView & ViewPager？

Question

我需要在 Android 2.2 及更高版本上选择图标的简单控制。
Gallery 对我来说是一个更好的解决方案，但它已被弃用，我必须改用 Horizo​​ntalScrollView 和 ViewPager。
但是如何轻松迁移？在这种情况下如何使用这些类和控件？我试图找到这个主题的完整示例，但找不到。

This gist from Dave Smith显示了一种使用 ViewPager 获得与 Gallery 非常相似的视觉结果的方法:

引用 my blog post on the topic在 ViewPager 中一次显示多个页面:

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.
