Question

Answer 1

Here is a layout design of your requirment. Take reference of these images. like

       TextView =  itemView.findViewById(R.id.nmr_of_students);  
        CircularImageViewstudent1 =  itemView.findViewById(R.id.student1);             
        CircularImageViewstudent2 =  itemView.findViewById(R.id.student2);
        CircularImageViewstudent3 =  itemView.findViewById(R.id.student3);
        CircularImageViewstudent4 =  itemView.findViewById(R.id.student4);
        CircularImageViewstudent5 =  itemView.findViewById(R.id.student5);

now use below layout and assign value to them. and you are good to go.

            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"

                >

Try this here is the working code for java

RecyclerViewActivity

public class RecyclerViewActivity extends AppCompatActivity {


    private  final Integer[] IMAGES = {R.drawable.nilesh, R.drawable.nilesh, R.drawable.nilesh, R.drawable.nilesh,
            R.drawable.nilesh, R.drawable.nilesh, R.drawable.nilesh, R.drawable.nilesh};
    private ArrayList<Integer> arrayList = new ArrayList<Integer>();

    RecyclerView myRecyclerView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_recycler_view);

        Collections.addAll(arrayList, IMAGES);

        myRecyclerView=findViewById(R.id.myRecyclerView);
        myRecyclerView.setLayoutManager(new LinearLayoutManager(this,
                LinearLayoutManager.HORIZONTAL,false));
        myRecyclerView.addItemDecoration(new OverlapDecoration());
        myRecyclerView.setHasFixedSize(true);
        myRecyclerView.setAdapter(new DataAdapter(this,arrayList));


    }

    public class OverlapDecoration extends RecyclerView.ItemDecoration {

        private final static int vertOverlap = -40;

        @Override
        public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
            final int itemPosition = parent.getChildAdapterPosition(view);


            outRect.set(0, 0, vertOverlap, 0);
