问题 I use Android Studio and Unity development, the Library packaged into aar file, and then the aar file as a Unity plug-in.

Kotlin - from a list of Maps, to a map grouped by key

由 戏子无情 提交于 2020-12-31 04:43:41
问题 I have a List<Map<Branch,Pair<String, Any>>> that I would like to convert in a single Map<Branch,List<Pair<String, Any>>> . So if I have an initial list with simply 2 elements : List 1. branch1 -> Pair(key1,value1) branch2 -> Pair(key2,value2) 2. branch1 -> Pair(key1a,value1a) I want to end up with : Map branch1 -> Pair(key1,value1) Pair(key1a,value1a) branch2 -> Pair(key2,value2) so a kind of groupBy, using all the values of the keys in the initially nested maps.. I have tried with list

老大爷都能看懂的RecyclerView动画原理

由 孤人 提交于 2020-12-30 21:05:55
如何阅读本篇文章 本文主要讲解RecyclerView Layout变化触发动画执行的原理。前半部分偏重原理和代码的讲解，后半部分通过图文结合场景讲解各个阶段的执行过程。 建议先粗略阅读前半部分的原理和代码篇，做到心中有概念，带着理论知识去阅读后半部分的场景篇。最后结合全文学到的知识，带着问题去阅读源码，效果会更好。 原理篇 1. Adapter的notify方法 用过RecyclerView的同学大概都应该知道Adapter有几个notify相关的方法，它们分别是： notifyDataSetChanged() notifyItemChanged(int) notifyItemInserted(int) notifyItemRemoved(int) notifyItemRangeChanged(int, int) notifyItemRangeInserted(int, int) notifyItemRangeRemoved(int, int) notifyItemMoved(int, int) 稍微有点开发经验的同学都知道，notifyDataSetChanged()方法比其它的几个方法更重量级一点，它会导致整个列表刷新，其它几个方法则不会。有更多开发经验的同学可能还知道notifyDataSetChanged()方法不会触发RecyclerView的动画机制
