Android Listview 减慢滚动速度 [英] Android Listview slow down scroll speed

问题描述

ListView 中的滚动速度对于我的应用程序来说太快了.我需要把它放慢很多.

The scroll speed in the ListView is way too fast for my application. I need to slow it down by a lot.

我不知道如何做到这一点.我在文档中唯一能找到的是一个setFriction"函数，它只在 API 级别 11 中受支持，以及一个静态的getScrollFriction"方法，它不能被覆盖并且没有相应的 setter.

I can't figure out how to do this. The only things I could find in the documentation are a "setFriction" function which is only supported in API Level 11, and a static "getScrollFriction" method which can't be overridden and has no corresponding setter.

这里有什么技巧 - 如何控制滚动速度?

What's the trick here - how do I control the scroll speed?

谢谢.

推荐答案

已验证这对于 API >= 11 非常有效:

Verified that this works really nicely for API >= 11:

listView.setFriction(ViewConfiguration.getScrollFriction() * FRICTION_SCALE_FACTOR)

请注意，滚动速度会随着摩擦力的增加而降低.为了适当地减少滚动动量，我最终使用了摩擦比例因子 10.YMMV.

Note that scroll speed decreases as friction increases. To decrease scroll momentum by a suitable amount, I ended up using a friction scale factor of 10. YMMV.
