问题描述
有什么区别? Android的文件不具有notifyDataSetInvalidated()的说明。我想也许你调用该函数通知所有已注册侦听器,但使用notifyDataSetChanged()不通知他们?
What is the difference? The android documentation doesn't have a description for notifyDataSetInvalidated(). I was thinking maybe you call that function to notify all registered listeners, but use notifyDataSetChanged() to not notify them?
推荐答案
变更是指更改的数据集。个别项目更新或项目被添加或删除。无效装置的数据源不再可用。
Changed means the data set changed. Individual items updated, or items were added or removed. Invalidated means the data source is no longer available.
