private String Doctor_Speciality;
private int Doctor_Rating;
private String Doctor_Image_Url;
public String getDoctor_ID() {
    return Doctor_ID;
}
public void setDoctor_ID(String doctor_ID) {
    Doctor_ID = doctor_ID; }
public String getDoctor_Name() {
    return Doctor_Name; }
public void setDoctor_Name(String doctor_Name) {
    Doctor_Name = doctor_Name; }
public String getDoctor_Email() {
    return Doctor_Email; }
public void setDoctor_Email(String doctor_Email) {
    Doctor_Email = doctor_Email; }
public String getDoctor_Phone() {
    return Doctor_Phone; }
public void setDoctor_Phone(String doctor_Phone) {
    Doctor_Phone = doctor_Phone; }
public String getDoctor_Speciality() { return Doctor_Speciality; }
public void setDoctor_Speciality(String doctor_Speciality) {
    Doctor_Speciality = doctor_Speciality; }
public int getDoctor_Rating() {
    return Doctor_Rating; }
public void setDoctor_Rating(int doctor_Rating) {
    Doctor_Rating = doctor_Rating; }
public String getDoctor_Image_Url() {
    return Doctor_Image_Url; }
public void setDoctor_Image_Url(String doctor_Image_Url) {

public Doctor(String doctor_ID, String doctor_Name, String doctor_Email, String doctor_Phone, String doctor_Speciality, int doctor_Rating, String doctor_Image_Url) {
    Doctor_ID = doctor_ID;
    Doctor_Name = doctor_Name;
    Doctor_Email = doctor_Email;
    Doctor_Phone = doctor_Phone;
    Doctor_Speciality = doctor_Speciality;
    Doctor_Rating = doctor_Rating;
    Doctor_Image_Url = doctor_Image_Url; }
public Doctor() { }

}

and my Adapter code is this

public class DoctorAdapter extends RecyclerView.Adapter<DoctorAdapter.DoctorViewHolder> {
private Context mcontext;
private List<Doctor> mDoctor;
public DoctorAdapter (Context context , List<Doctor> doctors){
    mcontext = context;
    mDoctor = doctors; }
@NonNull
@Override
public DoctorViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(mcontext).inflate(R.layout.image_doctor,parent,false);
    return new DoctorViewHolder(v); }
@Override
public void onBindViewHolder(@NonNull DoctorViewHolder holder, int position) {
    Doctor doctorCurrent = mDoctor.get(position);
    holder.txtNameDoctor.setText(doctorCurrent.getDoctor_Name());
    holder.txtSpecialityDoctor.setText(doctorCurrent.getDoctor_Speciality());
    Picasso.with(mcontext)
            .load(doctorCurrent.getDoctor_Image_Url())
            .fit()
            .centerCrop()
            .into(holder.imgDoctor); }
@Override
public int getItemCount() {
    return mDoctor.size(); }
public class DoctorViewHolder extends RecyclerView.ViewHolder{
    public TextView txtNameDoctor;
    public TextView txtSpecialityDoctor;
    public ImageView imgDoctor;
    public DoctorViewHolder(@NonNull View itemView) {
        super(itemView);
        txtNameDoctor = itemView.findViewById(R.id.doctor_name_recycler_card);
        txtSpecialityDoctor = itemView.findViewById(R.id.doctor_Speciality_recycler_card);
        imgDoctor = itemView.findViewById(R.id.doctor_image_recycler_card); }
}

}

and my card Layout

   <LinearLayout
    android:id="@+id/container_all_card"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    android:padding="10dp"
    android:background="@drawable/card_shape"
    >
    <ImageView
        android:id="@+id/doctor_image_recycler_card"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_margin="5dp"/>
    <LinearLayout
        android:layout_marginTop="5dp"
        android:id="@+id/container_text_card"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="10dp">
        <TextView
            android:layout_marginTop="10dp"
            android:id="@+id/doctor_name_recycler_card"
            android:textAppearance="@style/TextAppearance.AppCompat.Large"
            android:layout_width="230dp"
            android:layout_height="wrap_content"
            android:textStyle="bold"
            android:textColor="#ffffff" />
        <TextView
            android:id="@+id/doctor_Speciality_recycler_card"
            android:layout_width="250dp"
            android:layout_height="wrap_content"
            android:textColor="#ffffff"
            android:textSize="20dp" />
    </LinearLayout>
</LinearLayout>

and this is my RecyclerView in my Layout

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recycle_search_doctor"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

and this is my Activity java class

public class AllDoctorActivity extends AppCompatActivity {
private RecyclerView mRecyclerView ;
private DatabaseReference mdatabaseReference;
private DoctorAdapter mdoctorAdapter;
private List<Doctor> mdoctors;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_all_doctor);
    mRecyclerView = findViewById(R.id.recycle_search_doctor);
    mRecyclerView.setHasFixedSize(true);
    mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
    mdoctors = new ArrayList<>();
    mdatabaseReference = FirebaseDatabase.getInstance().getReference("doctors");
    mdatabaseReference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot snapshot) {
            for (DataSnapshot postSnapShot : snapshot.getChildren()){
                Doctor doctor = postSnapShot.getValue(Doctor.class);
                mdoctors.add(doctor);
            }
            mdoctorAdapter = new DoctorAdapter(AllDoctorActivity.this,mdoctors);
            mRecyclerView.setAdapter(mdoctorAdapter);
        }
        @Override
        public void onCancelled(@NonNull DatabaseError error) {
            Toast.makeText(AllDoctorActivity.this, error.getMessage(), Toast.LENGTH_LONG).show();
        }
    });
}

}

this is my doctor json code

    "doctors" : {
"-MEOD5GJqtMUR6V4XGbO" : {
  "-MGmxz1j6vmSzK0DlExJ" : {
    "doctor_Email" : "576",
