FirebaseRecyclerAdapter数据获取策略 [英] FirebaseRecyclerAdapter data fetching policy

问题描述

FirebaseRecyclerAdapter是否一次或仅在滚动时一次加载所有子项.假设我们有一个包含数千个聊天消息的引用，它们是否都将立即从数据库中获取?

Does FirebaseRecyclerAdapter load all children at a reference at once, or only upon scrolling. Suppose we have a ref containing thousands of chat messages, are they all going to be fetched from database at once??

推荐答案

FirebaseRecyclerAdapter加载您传入的DatabaseReference或Query匹配的所有子节点.它没有实现分页或其他形式的按需加载.

The FirebaseRecyclerAdapter loads whatever child nodes are matches by the DatabaseReference or Query you pass into it. It does not implement pagination or another form of load-on-demand.
