Pass data from firebase to object class

The issue I have is there're always Null Pointer Exception when I settext textview, so I cannot setText to my view.

I think the object didn't fill the field from getData method. How to fix this?

I am following this step https://firebase.google.com/docs/firestore/query-data/listen#listen_to_multiple_documents_in_a_collection and this https://stackoverflow.com/questions/52172309/parcelable-object-passing-from-android-activity-to-fragment.

This is the error output from android studio console

EDIT: Add constructor to add object from other object, I follow this https://stackoverflow.com/questions/869033/how-do-i-copy-an-object-in-java
This is the object about the field database and Parcelable

public class Layanan implements Parcelable {
    private String Nama;
    private String Syarat;
    private String Langkah;
    private String Lampiran;

    public Layanan(){
        //this("connect to internet", "connect to internet", "connect to internet", "connect to internet");
    }

//Constructor to add value from another object
    public Layanan(Layanan another) {
        this.nama = another.nama;
        this.syarat = another.syarat;
        this.langkah = another.langkah;
        this.lampiran = another.lampiran;
        this.deskripsi = another.deskripsi;
    }

    protected Layanan(Parcel in) {
        Nama = in.readString();
        Syarat = in.readString();
        Langkah = in.readString();
        Lampiran = in.readString();
    }

    public static final Creator<Layanan> CREATOR = new Creator<Layanan>() {
        @Override
        public Layanan createFromParcel(Parcel in) {
            return new Layanan(in);
        }

        @Override
        public Layanan[] newArray(int size) {
            return new Layanan[size];
        }
    };

    public static Layanan newInstance() {

        Bundle args = new Bundle();

        Layanan fragment = new Layanan();
        fragment.setArguments(args);
        return fragment;
    }

    private void setArguments(Bundle args) {

    }

    public String getNama() {
        return Nama;
    }

    public String getSyarat() {
        return Syarat;
    }

    public void setSyarat(String syarat) {
        Syarat = syarat;
    }

    public String getLangkah() {
        return Langkah;
    }

    public void setNama(String nama) {
        Nama = nama;
    }

    public void setLangkah(String langkah) {
        Langkah = langkah;
    }

    public String getLampiran() {
        return Lampiran;
    }

    public void setLampiran(String lampiran) {
        Lampiran = lampiran;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(Nama);
        dest.writeString(Syarat);
        dest.writeString(Langkah);
        dest.writeString(Lampiran);
    }
}

This is how i get data from Firebase, it's inside in activity

Layanan UP;
Layanan GU;
Layanan LS;


    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if(savedInstanceState == null) {
            //initMF();
            MainFragment homeFragment = MainFragment.newInstance();

            Bundle extras = new Bundle();


            getData("UP");
            Log.d(TAG, "This is the value name of " + UP.getNama()); //Output: This is the value name of null
            extras.putParcelable(UPParcelable, UP);
            if (UP.getSyarat()!=null) Log.d(TAG, "Value Added"); 
            if (UP.getSyarat()==null) Log.d(TAG, "Value not Added"); //Output: Value not Added

            homeFragment.setArguments(extras);
            getSupportFragmentManager().beginTransaction().add(R.id.main_activity, homeFragment).commit();
        }
...
...
    public void getData(final String p){
        mFirebase.collection("panduan_layanan")
                .whereEqualTo("nama", p)
                .addSnapshotListener(new EventListener<QuerySnapshot>() {

                    @Override
                    public void onEvent(@Nullable QuerySnapshot value, @Nullable FirebaseFirestoreException e) {
                        if (e != null){
                            Log.w(TAG, "onEvent:error", e);
                            return;
                        }
                        Layanan newLayanan = new Layanan();
                        for (QueryDocumentSnapshot doc : value) {
                            if (doc.get("nama") != null && doc.get("syarat") != null && doc.get("langkah") != null && doc.get("lampiran")!= null){
                                newLayanan.setNama(doc.getString("nama"));
                                newLayanan.setLampiran(doc.getString("lampiran"));
                                newLayanan.setLangkah(doc.getString("langkah"));
                                newLayanan.setSyarat(doc.getString("syarat"));
                                Log.d(TAG, "Update data: Success" + p);
                                Log.d(TAG, "This is the " + p + " syarat" + newLayanan.getSyarat());
                                if (newLayanan.getSyarat() != null) Log.d(TAG, "new layanan is" + newLayanan.getNama()); //new layanan isUP, it is work too
                            }
                        }
                        if (p.equals("UP")) UP = new Layanan(newLayanan);
                        Log.d(TAG, "the" + UP.getNama());  //Output theUP so it is work in here
                        if (p.equals("GU")) GU = new Layanan(newLayanan);
                        if (p.equals("LS")) LS = new Layanan(newLayanan);
                    }
                });
    }
...

Thank you so much

You can't do that because firebase execute that block asynchronously. So the field doesn't get value immediately just like Frank's comment said
