如何从arraylist每次在recyclerview中显示随机数据 [英] How to show random data every time in recyclerview from arraylist

问题描述

如何在每次打开recyclerview时显示随机数据

How do I show random data everytime I open recyclerview

例如，如果我有一个名称为

For example if I have a arraylist of name

arraydata={a,b,c,d,e,f,g,h,i,j,k,l}

在recyclerview中它总是按顺序显示意味着a先b然后c每次我们打开recyclerview它将显示相同的

In recyclerview it always show in sequence manner means a first then b then c Every time we open recyclerview It will show the same

无论如何我每次打开recyclerview时都显示不同的序列

Is there anyway to show different sequence everytime i open recyclerview

目前我正在使用

holder.textitem.setText(arraylistobject.get(position).getTextFun())

推荐答案

在将数据传递给 RecyclerView.Adapter 之前，您可以使用 Collections 对数据数组列表进行混洗:

You can use Collections to shuffle your array list of data before passing it to your RecyclerView.Adapter:

Collections.shuffle(arraylistobject)
