Я получаю эту ошибку при запуске приложения. Я разместил свой код ниже.

Я не знаю, где я иду Неправильно. Я включил все библиотеки и am usinhg picasao для получения изображений. Вот TestActivity.java

public class TestActivity extends AppCompatActivity { 
private RecyclerView recyclerView; 
private LinearLayoutManager linearLayoutManager; 
private DatabaseReference databaseReference; 
private FirebaseRecyclerAdapter<Post, PostViewHolder> mAdapter; 



@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_test); 
    databaseReference = FirebaseDatabase.getInstance().getReference().child("Posts"); 

    recyclerView = (RecyclerView) findViewById(R.id.posts_list); 
    recyclerView.setHasFixedSize(true); 

    recyclerView.setLayoutManager(new LinearLayoutManager(this)); 






} 
@Override 
public void onStart() { 
    super.onStart(); 
    mAdapter = new FirebaseRecyclerAdapter<Post, PostViewHolder>(
      Post.class, 
      R.layout.posts_row, 
      PostViewHolder.class, 
      databaseReference 

    ) 
    { 
     @Override 
     protected void populateViewHolder(PostViewHolder viewHolder, Post model, int position) { 
      viewHolder.setDetails(model.getDetails()); 
      viewHolder.setLocation(model.getLocation()); 
      viewHolder.setImages(getApplicationContext(),model.getImages()); 


     } 
    }; 

    recyclerView.setAdapter(mAdapter); 


} 
public static class PostViewHolder extends RecyclerView.ViewHolder { 

    View view; 

    public PostViewHolder(View itemView) { 
     super(itemView); 
     view = itemView; 

    } 

    public void setLocation(String location) { 
     TextView textView = (TextView) view.findViewById(R.id.post_location); 
     textView.setText(location); 
    } 

    public void setDetails(String details) { 
     TextView textView = (TextView) view.findViewById(R.id.post_location); 
     textView.setText(details); 
    } 

    public void setImages(Context context, String images) { 
     ImageView image = (ImageView) view.findViewById(R.id.post_image); 
     Picasso.with(context).load(images).into(image); 

    } 
} 

} 

Вот модель Post класс

public class Post { 
public String Details, Location, Images; 

public Post(String details, String location) { 
    Details = details; 
    Location = location; 
} 

public String getDetails() { 
    return Details; 
} 

public String getLocation() { 
    return Location; 
} 
public Post(){ 

} 

public String getImages() { 
    return Images; 
} 

}

Answer 1

Пожалуйста, попробуйте использовать этот класс модели

@IgnoreExtraProperties 
public class Post { 
    public String Details, Location, Images; 

    public Post(){ 

    } 

    public Post(String details, String location, String images) { 
     Details = details; 
     Location = location; 
     Images = images; 
    } 

    @Exclude 
    public Map<String, Object> toMap() { 
     HashMap<String, Object> result = new HashMap<>(); 
     result.put("Details", Details); 
     result.put("Location", Location); 
     result.put("Images", Images); 
     return result; 
    } 
} 

Answer 2

Есть несколько ошибок в вашем коде, который путает клиента Firebase:

1. ваших поля являются открытыми, но у вас также есть геттеры/сеттера
2. ваши имена полей начинаются с заглавной буквой

Если вы измените свой класс, чтобы быть более идиоматическими, это выглядит как

public class Post {  
    private String details, location, images; 

    public Post(){ } 
    public Post(String details, String location) { 
     this.details = details; 
     this.location = location; 
    } 

    public String getDetails() { 
     return details; 
    } 

    public String getLocation() { 
     return location; 
    } 

    public String getImages() { 
     return images; 
    } 
} 

в качестве альтернативы, вы можете иметь класс только с общественными полями (и не добытчиками/сеттеры):

public class Post {  
    public String Details, Location, Images; 

    public Post(){ } 
    public Post(String details, String location) { 
     Details = details; 
     Location = location; 
    } 
}
