Before watching this Do refer the previous Blog for implementing a RecyclerView. Please Click Here.

 

To Handle click event in RecyclerView we need make our View holder to implement the OnClickListner interface now we just need to overrride the onClick(View v) method of that interface .Below is the complete code of Adapter for the click event the text in bold are the changes made for handling the click event.

MyAdapter.java

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
    ArrayList arrayList;
    Context context;


    public MyAdapter(ArrayList arrayList, Context context) {
        this.arrayList = arrayList;
        this.context = context;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        //we call inflator over here...
        View v= LayoutInflater.from(parent.getContext()).inflate(R.layout.row,parent,false);

        return new MyViewHolder(v,context,arrayList);
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
//method is used to set the data in view.
        holder.textView.setText(""+arrayList.get(position));



    }

    @Override
    public int getItemCount() {

        //return the size of arraylist
        return arrayList.size();
    }

public static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{


//all the individual View objects  of the row is declared over here.
TextView textView;
Context ctx;
ArrayList arrayList=new ArrayList();
        public MyViewHolder(View itemView,Context context,ArrayList al) {
            super(itemView);
            itemView.setOnClickListener(this);
            textView = (TextView) itemView.findViewById(R.id.text1);
            arrayList=al;
            ctx=context;
        }

        @Override
        public void onClick(View view) {
            int position=getAdapterPosition();
            String data=""+arrayList.get(position);
            Toast.makeText(ctx, "sdsfs"+data, Toast.LENGTH_SHORT).show();



        }
    }
}
