我正在制作老虎机应用程序并使用kankan的方向盘。我想修改库，这样当旋转停止项目时，它将指向我设置的那个。我已经这样做但是有一个小故障表明我们已经将实际图像更改为我们想要的图像。怎么做到这一点？
更新
我已经研究了很多，如果我是对的，那么android滚动是基于持续时间和距离而不是项目。从kankan的轮库我可以获得当前项目。现在，我试图停止动画以及滚动，只要达到一定的持续时间并且该项目是我想要的项目（通过索引）。但这不起作用。请帮助!!

这是代码。通过这段代码，当插槽停止时我想让它滚动一些，直到它到达我从服务器上回收的图像位置。我可以做到这一点。但这提供了一个小故障。有没有办法在达到特定持续时间后立即停止滚动。
P.S。如果您需要更多详细信息，我可以为您提供。 P.P.S.截图不会给你任何关于这个问题的详细见解。
答案 0 :(得分：0)
经过几天的搜索，我终于做到了。我所要做的就是将插值器设置为LinearInterpolater，并将setCurrentItem设置为动画。
