老虎机不尽的名单如何获得对准线

问题描述

我试图实现与3无尽的ListView插槽MACHIN。我想做到这一点与滚动的看法，但我没有找到一个滚动视图解决循环。

I'm trying to implement a slot machin with 3 endless ListView. I wanted to do that with scroll view but I didn't find a solution to loop on a scrollView.

所以基本上，我有三个列表视图= 3我的老虎机列，当我点击按钮，我想滚动到一个随机位置（之间的随机整数0（含）和300（不含）这是我的列表大小）

So basically I have three listview = 3 columns of my slot machine and when I click on button I want to scroll to a random position (a random integer between 0 (inclusive) and 300 (exclusive) which is my lists size) :

Random r = new Random();
int rPos1 = r.nextInt(300 - 0) +0;
int rPos2 = r.nextInt(300 - 0) + 0;
int rPos3 = r.nextInt(300 - 0) +0;

listSlotOne.smoothScrollToPosition(rPos1);
listSlotTwo.smoothScrollToPosition(rPos2);
listSlotThree.smoothScrollToPosition(rPos3);

因此​​，所有这部分工作，但我不能管理每次显示结果一个干净的结果是我的屏幕：

So all this part is working but I can't manage to display each time as a result a clean result which mean three aligned lines on my screen ::

这里了良好的效果：三线对齐

在这里，一个坏的结果：行没有对齐

是否有可能来管理我的随机滚动的行为，以显示每一次不错的结果：三对准线。
我注意到，我的3点击播放按钮，我有一个很好的结果，但第四个点击后，我得到一个错误的结果与线条没有对齐，那么它是随机的。

Is it possible to manage the behaviour of my random scroll to display every time a good result : three aligned lines.I've noticed, for my 3 click on the play button I got a good result but after a fourth click I get a wrong result with not lines aligned and then it's random.

推荐答案

如果该smoothScrollToPosition（）方法不捕捉，你将不得不增加自己的管理单元意思是这样的：

If the smoothScrollToPosition() method doesn't snap, you are going to have to add your own snap meaning something like:

listSlotOne.smoothScrollToPosition((rPos1 % snap_height) * snap_height);
listSlotTwo.smoothScrollToPosition((rPos2 % snap_height) * snap_height);
listSlotThree.smoothScrollToPosition((rPos3 % snap_height) * snap_height);

或
    listSlotOne.smoothScrollToPosition（（rPos1 / snap_height）* snap_height）;
    listSlotTwo.smoothScrollToPosition（（rPos2 / snap_height）* snap_height）;
    listSlotThree.smoothScrollToPosition（（rPos3 / snap_height）* snap_height）;

or listSlotOne.smoothScrollToPosition((rPos1 / snap_height) * snap_height); listSlotTwo.smoothScrollToPosition((rPos2 / snap_height) * snap_height); listSlotThree.smoothScrollToPosition((rPos3 / snap_height) * snap_height);

我可能是错的，我不是100％肯定，但我相信，这将解决您的问题。

I may be wrong, I'm not 100% sure but I believe that will solve your problem.

我记得有MOD做虽然...好也许这会有所帮助。

Snap To GridI remember doing it with MOD though... well maybe this will help.
