How do I show random data everytime I open recyclerview

For example if I have a `arraylist` of name 

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

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 

Is there anyway to show different sequence everytime i open recyclerview 

Currently I am using 

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

```
