how to implement multiple view in one recyclerview in android

Question

How to create multiple views in one activity, I had tried it by using the multi Type view but it's not working Is it the right way or I need to add multiple recyclerview in one activity and hide the visibility of the recyclerview according to the filter

           public class Report_Adapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {// MultipleView Adapter class where multpleview type is binding
                    Context context;
                    List<BillModel> list;
                    private static final int DAILY_REPORT = 1; //these are the view type position variable

                    private static final int YEARLY_REPORT = 3;
                    private static final int MONTHLY_REPORT = 2;
                    private static final int ITEM_WISE_REPORT = 4;
                    private static final int DETAILED_SALES_REPORT = 5;


            public Report_Adapter(Context context, List<BillModel> list) { //construct which is using into the activity for setAdapter.
                        this.context = context;
                        this.list = list;}

                    @Override
                    public int getItemViewType(int position) { //here checking the ViewType position which is getting wrong here
                        if (position == 1)  //if position equals to viewtype position return the Dailylayout View other wise will go on second position
                            return DAILY_REPORT;
                        else if (position==2){
                            return MONTHLY_REPORT;
                        }
                        else if (position ==3)
                            return CUSTOMER_REPORT;
                        else
                            return TOTAL_SALES_REPORT;
                    }

                    @Override

                        View view = null;
                        RecyclerView.ViewHolder viewHolder = null;
                          if (i == DAILY_REPORT) {

I want this type of functionality for multiple search data from the database as you can see in this image2

Answer 1

first you must create 2 layout xml . after that inside recyclerview adapter TYPE_CALL and TYPE_EMAIL are two static values with 1 and 2 respectively in adapter class.

now Define two static values ​​at the Recycler view Adapter class level for example : private static int TYPE_CALL = 1; private static int TYPE_EMAIL = 2;

Now create view holder with multiple views like this:

class CallViewHolder extends RecyclerView.ViewHolder {

    private TextView txtName;
    private TextView txtAddress;

    CallViewHolder(@NonNull View itemView) {
        super(itemView);
        txtName = itemView.findViewById(R.id.txtName);
        txtAddress = itemView.findViewById(R.id.txtAddress);
    }
}
class EmailViewHolder extends RecyclerView.ViewHolder {

    private TextView txtName;
    private TextView txtAddress;

    EmailViewHolder(@NonNull View itemView) {
        super(itemView);
        txtName = itemView.findViewById(R.id.txtName);
        txtAddress = itemView.findViewById(R.id.txtAddress);
    }
}

Now code as below in onCreateViewHolder and onBindViewHolder method in recyclerview adapter:

@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int viewType) {
    View view;
    if (viewType == TYPE_CALL) { // for call layout
        view = LayoutInflater.from(context).inflate(R.layout.item_call, viewGroup, false);
        return new CallViewHolder(view);

    } else { // for email layout
        view = LayoutInflater.from(context).inflate(R.layout.item_email, viewGroup, false);
        return new EmailViewHolder(view);
    }
}
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder viewHolder, int position) {
    if (getItemViewType(position) == TYPE_CALL) {
        ((CallViewHolder) viewHolder).setCallDetails(employees.get(position));
    } else {
        ((EmailViewHolder) viewHolder).setEmailDetails(employees.get(position));
    }
}
