display random page on recycleview

could I display random page when our recycleview apps? I want to put a floatbutton on my detailactivity.javaclass and when I click it must display a page with my string data and image files.

 mFlowerData = new FlowerData("Rose", getString(R.string.description_flower_rose),
            R.drawable.rose);
    mFlowerList.add(mFlowerData);
    mFlowerData = new FlowerData("Carnation", getString(R.string.description_flower_carnation),
            R.drawable.carnation);

how can ı do it I want to display it my last page.
