[英]How to detect when the scrollbar has reached the top or bottom of webpage?

原文 2012-07-24 11:57:45 9 1 android/ webview

I am working with WebView and my problem is that whenever the scrollbar reaches to the end or top of WebView it should indicate this to me with some boolean value so that I can display the next and previous page correspondingly. 我正在使用WebView ，但我的问题是，每当滚动条到达WebView的末尾或顶部时，都应使用一些布尔值向我表明这一点，以便我可以相应地显示下一页和上一页。

I am working on a project and I want to show a HTML file as a html reader so I want to know whenever the scrollbar reaches the end of webpage so I can load the further pages. 我正在做一个项目，我想将HTML文件显示为html阅读器，所以我想知道滚动条何时到达网页的末尾，以便我可以加载其他页面。
