Solution 1:

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

Collections.shuffle(arraylistobject)

Solution 2:

You can use Random class from java.util package, it's nextInt() method returns pseudorandomintvalue in range from 0 inclusive to value passed as argument exclusive:

import java.util.*;

Randomrand=newRandom();
holder.textitem.setText(arraylistobject.get(rand.nextInt(arraylistobject.size()).getTextFun());

rand.nextInt(arraylistobject.size()) in that case returns value from 0 to size of your arraylistobject exclusive.
