The problem is, I am getting the runtime error when I trying to get firebase data into a RecyclerView. Error is
java.lang.RuntimeException: java.lang.NoSuchMethodException I have implemented it last time but now I can't get it what have I done wrong.
My main class setting firebase initialization-
public class Shayari extends AppCompatActivity { private RecyclerView recyclerView; private DatabaseReference reference; TextView texttest; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_shayari); texttest=findViewById(R.id.test);//just for test reference= FirebaseDatabase.getInstance().getReference("Catogory/Love"); recyclerView=findViewById(R.id.recyclerview); recyclerView.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL,false)); recyclerView.setHasFixedSize(true); FirebaseRecyclerAdapter<DataModel,DataViewHolder> adapter = new FirebaseRecyclerAdapter<DataModel, DataViewHolder>( DataModel.class, R.layout.item_recyclerview, DataViewHolder.class, reference) { @Override protected void populateViewHolder(DataViewHolder viewHolder, DataModel model, int position) { viewHolder.setTitle(model.getTitle()); viewHolder.setShayari(model.getShayari()); } }; recyclerView.setAdapter(adapter); texttest.setText(reference.toString()); } public class DataViewHolder extends RecyclerView.ViewHolder{ TextView text_title,text_shayari; public DataViewHolder(View itemView) { super(itemView); text_title=itemView.findViewById(R.id.titletext); text_shayari=itemView.findViewById(R.id.shayaritext); } public void setShayari(String shayari) { text_shayari.setText(shayari); } public void setTitle (String title){ text_title.setText(title); } } } Model Class for getting data-
class DataModel { private String titles, shayaris; public DataModel() { } public DataModel(String titles, String shayaris) { this.titles = titles; this.shayaris = shayaris; } public String getTitle() { return titles; } public void setTitle(String title) { this.titles = title; } public String getShayari() { return shayaris; } public void setShayari(String shayari) { this.shayaris = shayari; } } This is my firebase hierarchy structure
