Android的滚动型，确认当前的滚动 [英] Android ScrollView, check if currently scrolling

问题描述

有没有一种方法来检查，如果滚动型标准目前正在滚动？

Is there a way to check if a standard ScrollView is currently being scrolled?

如果方向是向上或向下无所谓，我只需要检查它是否是目前在所有的滚动。

Doesn't matter if the direction is upwards or downwards, i only need to check whether it's currently being scrolled at all.

推荐答案

滚动型以目前的形式用于检测滚动事件不提供回调。有两种解决方法可供选择：

ScrollView in its current form does not provide a callback for detecting scroll events. There are two workarounds available:

1 使用的ListView 和实施的 OnScrollListener 。

1. Use a ListView and implement OnScrollListener.

2 从现有的滚动型实施派生自定义类和<一个href=\"http://stackoverflow.com/questions/3948934/synchronise-scrollview-scroll-positions-android/3952629#3952629\">extend它提供的回调，滚动事件的。

2. Derive a custom class from the existing ScrollView implementation and extend it to provide callbacks for scroll events.
