什么时候调用onCreateViewHolder，为什么？回收站视图

[英]When is onCreateViewHolder called and why? RecyclerView

原文 2018-10-27 18:17:36 9 1 android/ android-recyclerview

到目前为止，我认为当我使用adapter = new RecyclerViewAdapter(this, list)调用适配器的构造函数时，会调用RecyclerView.Adapter中的onCreateViewHolder ，但是我意识到实际上是在所有代码之后在Activity的onCreate方法末尾调用它的执行该命令，是因为RecyclerView不会创建不必要的视图，而是仅创建多少可以容纳在设备屏幕上的视图吗？

1 个解决方案

It's called when RecyclerView.LayoutManager determines which and how many views will be visible within RecyclerView , and RecyclerView.RecycledViewPool does not contain enough ViewHolder s to re-use. 当RecyclerView.LayoutManager确定在RecyclerView可以看到哪些视图以及多少个视图，并且RecyclerView.RecycledViewPool包含的ViewHolder不足以ViewHolder ，将调用该方法。

This usually happens during each layout phase and on (first) scroll. 这通常发生在每个布局阶段以及上一次滚动时。
