Android Arraylist с возможностью Drag and drop

Как сделать Fragment с RecyclerView в котором будет Arraylist с MaterialCardView в котором будут TextView и ImageView но при этом при нажатии на ImageView можно перетаскивать по RecyclerView меняя местами с другими MaterialCardView.То есть Drag and drop. В примере material-components-android используется generateCardNumbers но я не знаю как его заменить на Arraylist так что бы я сам мог выставлять количество проявляемых MaterialCardView и мог менять в них текст. Как это сделать?

Я знаю что кода много, поэтому загрузил исходники в github https://github.com/Buldog18/Drag-and-drop
