        app:emptyTextSize="14sp"
        app:errorButtonText="errorButRoxa"

        app:errorImageHeight="50dp"
        app:errorImageWidth="30dp"
        app:errorMessage="errorRoxa"

        app:loadingProgressBarColor="@color/green"
        app:loadingProgressBarRadius="200dp"
        app:loadingProgressBarSpinWidth="10dp"
   

Java

Step 2: extend SliderAdapter

in first step you must create an adapter to manage empty Recycle View By this Library adapt your data model with slides. example implemented adapter with 3 slides:

public class SimpleRVAdapter extends RecyclerView.Adapter<SimpleRVAdapter.SimpleViewHolder> {

    private String[] dataSource;

    public SimpleRVAdapter(String[] dataArgs) {
        dataSource = dataArgs;
    }

    @Override
    public SimpleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new SimpleViewHolder(new TextView(parent.getContext()));
    }

    public static class SimpleViewHolder extends RecyclerView.ViewHolder {
        public TextView textView;

        public SimpleViewHolder(View itemView) {
            super(itemView);
            textView = (TextView) itemView;
        }
    }

    @Override
    public void onBindViewHolder(SimpleViewHolder holder, int position) {
        holder.textView.setText(dataSource[position]);
    }

    @Override
    public int getItemCount() {
      //  return 0;
          return dataSource.length;
    }

}

Step 3: setAdapter in your Activity for use EmptyState

emptyState handled by this library so don't need to worry about that.you should need too setAdapter.

emptyStateRecyclerView.setAdapter(new SimpleRVAdapter(new String[]{}));

Step 4: ErrorState and LoadingState

if you want to use ErrorState and LoadingState ,you should need to add these methods:

 emptyStateRecyclerView.showError();
 emptyStateRecyclerView.showLoading();

So that is Sample Of You Activity:

import com.roxa.emptystatehelper.EmptyStateRecyclerView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        EmptyStateRecyclerView emptyStateRecyclerView = findViewById(R.id.recyclerview_main);

          emptyStateRecyclerView.setAdapter(new SimpleRVAdapter(new String[]{}));

          emptyStateRecyclerView.showError();
          emptyStateRecyclerView.showLoading();

    }
}
