I have several ListViews that I want to implement into a ViewPager. I've got the compatibility pack loaded and everything. But I haven't seen any complete examples of how to do this.

When the pages are scrolled, the tabs are switched and tabs are changed, the current page is changed too. I am using a class that extends FragmentStatePagerAdapter as adapter in the pageview. The problem is that when the device rotates, the getItem from the page adapter is not called and looks like the fragments references are not right. That's a huge problem, since the user must fulfill some fields inside the pager. These fields are recovered in correctly on the

Bug描述 有一个界面，外层是ViewPager，内层嵌了一个RecyclerView。RecyclerView有自己的点击和滑动事件，造成外层的ViewPager无法左右滑动。 山重水复 尝试了很多方法，比如可能是外层的ViewPager和内层的RecyclerView有滑动冲突的问题。于是想方设法拦截其中的某项事件监听，但并无卵用。最后折腾半天无果，无奈，按照项目的写法逻辑重新实现了一遍，发现没有发生滑动冲突。 日了狗了。 感觉问题并不在于此。 柳暗花明 逐层查找，从ViewPager的Activity查找到ViewPager每个页面所显示的Fragment的编码，该Fragment的布局文件是一个RecyclerView，查一下该RecyclerView的适配器Adapter，码神保佑，我注意到了其中的【 onCreateViewHolder() 】找到其关联的布局文件，进去看一眼，好神奇，竟然是一个 TextView 。 问题解决 里面用到了一个属性 android:singleLine="true" 这个属性已被谷歌废弃，替换成 android:lines="1" android:ellipsize="end" 问题解决。 参考： https://blog.csdn.net/ldqsxsl/article/details/68485514 总结 1。在TextView中
