recyclerview

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

Any ideas how to implement it from the scratch? 回答1: As of v22.2.0, the Android support team has included an ItemTouchHelper class that makes swipe-to-dismiss and drag-and-drop pretty simple. This may not be as full-featured as some of the libraries out there, but it comes directly from the Android team. Update your build.gradle to import v22.2.+ of the RecyclerView library compile 'com

There is no equivalent to the OnScrollListener.onScroll(...) method on ListViews. I tried to work with View.getGlobalVisibleRect(...) , but that hack is too ugly and does not always work too. Someone any ideas? 回答1: First / last visible child depends on the LayoutManager . If you are using LinearLayoutManager or GridLayoutManager , you can use int findFirstVisibleItemPosition(); int findFirstCompletelyVisibleItemPosition(); int findLastVisibleItemPosition(); int
