What is wrong ?
all code
https://github.com/Madzia123/CallInert
Apparently, In the onBindViewHolder method the person object is null. And you are trying to invoke getName() method on null reference. So it is causing the error. Make sure to have valid reference to Person object.
You are adding null person to personList at
public void addPerson(Person person) {
int position = getItemCount();
personList.add(position, person);
notifyDataSetChanged();
}
That's why when you call
person = personList.get(position);
it returns null
try this
public void addPerson(Person person) {
if(person==null){
Log.e("error","person is null");
return;
}
int position = getItemCount();
personList.add(position, person);
notifyDataSetChanged();
}
final Person person = personList.get(position);
holder.name.setText(person.getName());
From your attached logs, seems that you are getting NullPointerException when calling Person.getName() from your adapter's onBindViewHolder().
java.lang.NullPointerException: Attempt to invoke virtual method
'java.lang.String magdalena.pl.callmistake.Person.getName()' on a null
object reference
Solution:
Update your PersonAdapter as below:
public class PersonAdapter extends RecyclerView.Adapter<PersonAdapter.PersonViewHolder> {
Context context;
private LayoutInflater layoutInflater;
// Person List
public List<Person> personList;
public PersonAdapter(Context context, List<Person> persons) {
this.context = context;
this.personList = persons;
layoutInflater= LayoutInflater.from(context);
}
#Override
public PersonViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = layoutInflater.inflate(R.layout.item_card, parent, false);
// View holder
PersonViewHolder holder = new PersonViewHolder(view);
return holder;
}
#Override
public void onBindViewHolder(PersonViewHolder holder, int position) {
// Person
Person person = personList.get(position);
holder.name.setText(person.getName());
holder.surname.setText(person.getSurname());
}
#Override
public int getItemCount() {
return personList.size();
}
public void addPerson(Person person) {
int position = getItemCount();
personList.add(position, person);
notifyDataSetChanged();
}
public class PersonViewHolder extends RecyclerView.ViewHolder {
public TextView name, surname;
public PersonViewHolder(View itemView) {
super(itemView);
name = (TextView) itemView.findViewById(R.id.person_name);
surname = (TextView) itemView.findViewById(R.id.person_surname);
}
}
}
In your Activity do this:
..........
.................
Context mContext;
// RecyclerView
RecyclerView recyclerView;
PersonAdapter personAdapter;
RecyclerView.LayoutManager layoutManager;
// Values
List<Person> listPerson;
#Override
protected void onCreate(Bundle savedInstanceState) {
.......
............
// Context
mContext = this;
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
// Set your recyclerView layout manager
// Person List
listPerson = new ArrayList<Person>();
// Add some person data to list from API call or from Database
// Here I added some for test purpose
listPerson.add(new Person("Hello Android", "Android", "google#gmail.com", "21132342423", "Lorem ipsum"));
listPerson.add(new Person("Hello Android", "Android", "google#gmail.com", "21132342423", "Lorem ipsum"));
// specify an adapter
personAdapter = new PersonAdapter(mContext, listPerson);
recyclerView.setAdapter(personAdapter);
}
...............
...........................
Hope this will help you~
first pass the data from where you call this adapter.
adapter = new PersonAdapter(getContext(),(ArrayList<Person>) list);
use arraylist.method to access class method.
holder.name.setText(person.personList(position).getName());

Since you pass this path to the FirebaseUI adapter:
FirebaseDatabase.getInstance().getReference().child("Retailer").child(username).child("r_history").child(datenew)
Firebase will read each child node under that path and try to create a retailer_model_datewise_dispwhenpressed object out of it.
This works fine for the child 1, as it has the properties that your class has. But then Firebase tries to do the same for Pmode, and that is just a string value, which is not a valid retailer_model_datewise_dispwhenpressed object.
You'll have to ensure that you only have child nodes that are valid retailer_model_datewise_dispwhenpressed objects under the path that you load.
I want to show people's information including a picture.
Here is User.class
public class User {
//파이어 스토어 필드 변수명과 타입이 같아야 한다. ex) 프사 라즈 INTP 구일 23
String name, mbti, region, age, profile_image;
public User(){
//must be empty
}
public User(String name, String mbti, String region, String age, String profile_image) {
this.name = name;
this.mbti = mbti;
this.region = region;
this.age = age;
this.profile_image = profile_image;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getMbti() { return mbti; }
public void setMbti(String mbti) {this.mbti = mbti; }
public String getRegion() { return region; }
public void setRegion(String region) { this.region = region; }

public void setAge(String age) { this.age = age; }
public String getProfile_image() { return profile_image; }
public void setProfile_image(String profile_image) { this.profile_image = profile_image; }}
And here is the MyAdapter class
Context context;
ArrayList<User> userArrayList;
public MyAdapter(Context context, ArrayList<User> userArrayList) {
this.context = context;
this.userArrayList = userArrayList;
}
#NonNull
#Override
public MyAdapter.MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {

holder.region.setText(user.region);
holder.age.setText(user.age);
Glide.with(context).load(user.getProfile_image()).into(holder.imgprofile);
}
#Override

}
public static class MyViewHolder extends RecyclerView.ViewHolder {

imgprofile = itemView.findViewById(R.id.main_profileimg);
}
}
In my MainActivity I use firestore.collection() and userArrayList.add(dc.getDocument().toObject(User.class)) So recyclerview can have people's information.
But Pictures are stored in Firebase storage -> profile/pics -> uid.jpg..
I'm beginner so I can't transform code userArrayList.add(dc.getDocument().toObject(User.class))
firestore.collection("Users")
.whereEqualTo("mbti",mainsearch_mbti)
.orderBy("time",Query.Direction.DESCENDING).limit(50)
.addSnapshotListener(new EventListener<QuerySnapshot>() {
#Override
public void onEvent(#Nullable QuerySnapshot value, #Nullable FirebaseFirestoreException error) {
if(error != null){
if(progressDialog.isShowing()){
progressDialog.dismiss();
}
Log.e("Firestore error",error.getMessage());
return;
}
for (DocumentChange dc : value.getDocumentChanges()){
if (dc.getType() == DocumentChange.Type.ADDED){
userArrayList.add(dc.getDocument().toObject(User.class));
}
myAdapter.notifyDataSetChanged();
if(progressDialog.isShowing()){
progressDialog.dismiss();
}
}
}
});
You can take data with value.getDocuments() function.
for (DocumentSnapshot snapshot : value.getDocuments()) {
Map<String,Object> dataMap = snapshot.getData();
String abc = (String) dataMap.get("abc");
}

You are creating a second instance instead of passing the one you set the arguments on.

check if "product_list_item" root ViewGroup width is : wrap_content not match_parent.
layou/product_list_item.xml:
<LinearLayout
android:layout_height="wrap_content"
of course you encounter this problem if it was match_parent.
Seems all good, But one thing try to invalidate cache and restart your android studio

I have a realm database model which i want to display in arecyclerview,
every row in the database model have a String name,int age and a boolean favourite,when i try to save the boolean value in the RecyclerviewAdapter

this the model

this is the interface
