Android 中 RecyclerListView 内的可扩展 ListView
Expandable ListView inside a RecyclerListView in Android
如何在 RecyclerView ListView 中放置一个 Expandable ListView 如何做到这一点？
像这样
不展开ExpandingListView
随着扩展ExpandableListView
在 RecyclerView 中使用了可扩展列表视图。
一切正常，但在扩展时，当给定高度作为 Recycler 视图项目高度中的包装内容时，我们无法查看子项目。
在给定 Recyclerview 项目高度的固定高度的情况下查看相同的内容，但效率不高。
还有其他方法吗？

ExpandableListAdapter 视图由于正文大小限制而无法包含。
但它是简单的文本视图，没有太多复杂的。
compile 'net.cachapa.expandablelayout:expandablelayout:2.9.1' 使用此库进行可扩展布局。

ExpandableListAdapter 视图由于正文大小限制而无法包含。 但它是简单的文本视图，没有太多复杂的。
compile 'net.cachapa.expandablelayout:expandablelayout:2.9.1' 使用此库进行可扩展布局。
