安卓：滚动型“setOnScrollListener”（如ListView控件） [英] Android: ScrollView 'setOnScrollListener' (like ListView)

问题描述

我想要做的事情，当用户滚动> 90％了，所以我想我可能只是增加一个onScrollListener就像我会在一个ListView。不幸的是，滚动型似乎并不有一个类似的方法。有什么办法，我可以做我想做的;得到一个通知，当用户滚动约90％下降？

I want to do something when the user has scrolled >90% down, so I thought I could just add a onScrollListener like I would in a ListView. Unfortunatly, ScrollView doesn't seem to have a similar method. Is there any way I can do what I want; getting a notification when the user scrolls approx 90% down?

谢谢， 埃里克

推荐答案

您可以尝试延长滚动型并覆盖查看＃onScrollChanged 和做你检查那里。你必须扩展滚动型，因为 onScrollChanged 是一个受保护的方法。

You can try extending ScrollView and overriding View#onScrollChanged and the doing your checks there. You have to extend ScrollView since onScrollChanged is a protected method.
