How to hide part of a string in a recyclerview?

I have a recyclerview where I am displaying a string which contains a id,name and contact number as a single string.I would like to hide the id in the string.I am using the following code to add the string to the array list.I am displaying the concatenated string in a textview like (1-XYZ 0123456789)

private void showGuestDetails(String response) {
Guest_info guest_info = new Guest_info(response);

String guestid[] = guest_info.guest_id;

for (int i = 0; i < guestid.length; i++) {
list.add(guest_info.guest_id[i] + "-" + guest_info.guest_name[i] + " " + guest_info.guest_mobile[i]);


This is the adapter class that I am using:-

public class GuestAdapter extends RecyclerView.Adapter<GuestAdapter.GuestViewHolder> {

private List<String> list_item ;
public Context mcontext;
private BookingActivity bookingActivity;

public GuestAdapter(List<String> list, Context context, BookingActivity bookingActivity) {

list_item = list;
mcontext = context;
this.bookingActivity =bookingActivity;

// Called when RecyclerView needs a new RecyclerView.ViewHolder of the given type to represent an item.
public GuestAdapter.GuestViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a layout
View view = LayoutInflater.from(parent.getContext()).inflate(
R.layout.list_item, null);

GuestViewHolder myViewHolder = new GuestViewHolder(view);
return myViewHolder;

// Called by RecyclerView to display the data at the specified position.
public void onBindViewHolder(final GuestViewHolder viewHolder, final int position ) {


viewHolder.guest_name.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {




//Returns the total number of items in the data set hold by the adapter.
public int getItemCount() {
return list_item.size();

// initializes textview in this class
public static class GuestViewHolder extends RecyclerView.ViewHolder {

public TextView guest_name;

public GuestViewHolder(View itemLayoutView) {

guest_name = (TextView) itemLayoutView.findViewById(;


Is there a way by which I will be able to display everything after the
hyphen and hide everything before the hyphen including the hyphen. Any
help or suggestion is appreciated. Thank you.

try this

String[] separated = list.get(position).split("-");
separated[0]; // this will contain your ID eg 1
separated[1]; // this will contain your remaining string eg XYZ 0123456789
