//For displaying the row as linear list view        
case R.id.ivGrid:
    ivList.setVisibility(View.VISIBLE);
    ivGrid.setVisibility(View.GONE);
    LinearLayoutManager llm = new LinearLayoutManager(context);

//For displaying the row as gridview
case R.id.ivList:
    ivList.setVisibility(View.GONE);
    ivGrid.setVisibility(View.VISIBLE);
    GridLayoutManager glm = new GridLayoutManager(this,2,GridLayoutManager.VERTICAL, false);
    rcvProducts.setLayoutManager(glm);
    break;

GRIDview

LISTview

Answer 1

Just use a GridLayoutManager and change the span count from 1 to 2 and back again.

view.setOnClickListener(new View.OnClickListener(){
    public void onClick(View view){
        GridLayoutManager layoutManager = (GridLayoutManager) grid.getLayoutManger();
        layoutMananger.setSpanCount(layoutManager.getSpanCount() == 2 ? 1 : 2);
    }
})

Answer 2

1. Maintain 2 adapters, one for ListView and one for GridView.
2. On button click, change the adapter to RecyclerView.
3. Listview.setAdapter(gridAdapter) (or) ListView.setAdapter(listAdapter)
