停止用户滚动到RecyclerView设置位置 [英] Stop user scroll to set position on RecyclerView

问题描述

所以我有一个问题，我是很新的机器人编程，它已经只有6-8个星期，因为我已经开始编程的Andr​​oid应用程序，所以我可能是盲目的，而不是见容易的答案，但这里是我的问题

so i've got a problem, i'm quite new to android programming, it's been only 6-8 weeks since i've started programming android apps so i may be blind and not see the easy answer but here's my problem:

我在做一个学校项目，我试图建立一个类似日历一个在今天的经济日历拆分视图（唯一的下方位置）

I'm making a school project and i'm trying to develop a similar calendar to the one in Today's Calendar split view (The one below here)

所以我做了一个GridLayoutManager看起来像这样一个RecyclerView：

So i've made a RecyclerView with a GridLayoutManager that looks like this:

和，直到在这里一切都很好，但我想要实现，设置今天的日期的日历按钮，事情是，当我滚动了一扔，然后设置RecyclerView立场scrollToPositionWithOffset（位置， 0）;视图保持从第一一扔上涨的势头，设置位置，然后不断滚动，直到动能消失

And up until here everything's fine, but i'm trying to implement the button that sets the calendar on today's date, the thing is that when i'm scrolling with a fling and then set the RecyclerView position with scrollToPositionWithOffset(position, 0); the view keeps the momentum gained from the first fling, sets the position and then keeps on scrolling until the momentum is gone

我已经搜查了很多，以找到一个解决方案，当我使用的GridView，而不是RecyclerView我用smoothScrollToPositionFromTop（），它停止滚动，然后setSelection（）来定位，但在GridView跳过的帧，我不得不变化，这里RecyclerView没有smoothScrollToPositionFromTop和smoothScrollToPosition不停止滚动，同样没有scrollToPosition或scrollToPositionWithOffset。

I've searched a lot to find a solution, when i was using gridView instead of RecyclerView i used smoothScrollToPositionFromTop() which stopped the scrolling and then the setSelection() to position it, but the gridView skipped frames and i had to change, here with RecyclerView there is no smoothScrollToPositionFromTop and smoothScrollToPosition doesn't stop the scroll, neither does scrollToPosition or scrollToPositionWithOffset.

发现这个，但不利于<一href="https://stackoverflow.com/questions/26875061/scroll-recyclerview-to-show-selected-item-on-top">Scroll RecyclerView显示选择项目上面

和其他许多人没有帮助。

and many others that didn't help.

我认为实现我自己的滚动逻辑，但是，当我看着它，我的头爆炸了，我不知道从哪里开始。

I considered implementing my own scrolling logic but when i looked into it my head exploded and i wouldn't know where to begin.

有谁知道如何解决这个问题？

Does anyone know how to solve this?

推荐答案

你知道吗？ RecyclerView 有一个 stopScroll（）方法停止滚动的进展如何？

Did you know that RecyclerView has a stopScroll() method to stop a scroll in progress?
