如何创建一个圆形（环形）RecyclerView [英] How to create a Circular (endless) RecyclerView

问题描述

我试图让我的RecyclerView环回我的列表的开始。我已搜查所有在互联网上，并已成功地检测到时，我已经达到了我的列表的末尾但我不能确定在哪里可以从这里出发。

这是我目前使用的检测列表的到底是什么（找到<一href=\"http://stackoverflow.com/questions/26543131/how-to-implement-endless-list-with-recyclerview\">here):

  @覆盖
    公共无效onScrolled（RecyclerView recyclerView，诠释DX，DY INT）{        visibleItemCount = mLayoutManager.getChildCount（）;
        totalItemCount = mLayoutManager.getItemCount（）;
        pastVisiblesItems = mLayoutManager.findFirstVisibleItemPosition（）;        如果（装载）{
            如果（（visibleItemCount + pastVisiblesItems）＆GT; = totalItemCount）{
                加载= FALSE;
                Log.v（...，+ visibleItemCount）;
            }
        }
 }
 

当滚动到最后，我想的观点是可见的，而从列表的顶部显示用数据，或者当滚动到列表我会从该列表的底部显示数据的顶部。

例如：
结果
视图1
视图2
VIEW3
View4
View5

View5
视图1
视图2
VIEW3
View4

解决方案

有没有使其无限的方式，但有一种方法来使它看起来像inifite。在您的适配器覆盖 getCount将（）方法返回的东西大如 Integer.MAX_VALUE的

和对的getItem（）和 getView（）法模分（％）由真实项目编号位置。

在结束在中间设置当前项目的东西。

I am trying to make my RecyclerView loop back to the start of my list. I have searched all over the internet and have managed to detect when I have reached the end of my list however I am unsure where to proceed from here.

This is what I am currently using to detect the end of the list (found here):

 @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {

        visibleItemCount = mLayoutManager.getChildCount();
        totalItemCount = mLayoutManager.getItemCount();
        pastVisiblesItems = mLayoutManager.findFirstVisibleItemPosition();

        if (loading) {
            if ( (visibleItemCount+pastVisiblesItems) >= totalItemCount) {
                loading = false;
                Log.v("...", ""+visibleItemCount);
            }
        }
 }

When scrolled to the end, I would like to views to be visible while the displaying data from the top of the list or when scrolled to the top of the list I would display data from the bottom of the list.

For example:
View1 View2 View3 View4 View5

View5 View1 View2 View3 View4

解决方案

There is no way of making it infinite, but there is a way to make it look like inifite. In your adapter override getCount() method to return something big like Integer.MAX_VALUE

And on getItem() and getView() method modulo divide (%) position by real item number.

At the end set current item to something in a middle.
