推荐答案
API提供了这样的方法,但它们受到保护,所以在我看来,最好的做法是创建包装类(扩展滚动型),并让这些方法公开,特别是 onScrollChanged
和 onOverScroll
。
API provides such methods, but they are protected, so the best practice in my opinion, is to create wrapper class (extend ScrollView) and make those methods public, particularly onScrollChanged
and onOverScroll
.
