I wish this help you Best to define your adapter as an abstract class and make two separate class that you want to have for those two places.
I guess you want to have two different onCreateViewHolder functions.
code :
public abstract class AdapterCafe extends RecyclerView.Adapter<AdapterCafe.MyViewHolder> {
 // Add every thing that are not different for the two cases.
 // Anything except `onCreateViewHolder`
class Case1Adapter extends AdapterCafe {

 // Now override `onCreateViewHolder`
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    View view = LayoutInflater.from(context).inflate(R.layout.cafe_card, parent, false);

    MyViewHolder holder = new MyViewHolder(view);
    return holder;

class Case2Adapter extends AdapterCafe {

public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    View view2 = LayoutInflater.from(context).inflate(R.layout.filppers_item, parent, false);

    MyViewHolder holder2 = new MyViewHolder(view2);
    return holder;

it fixes the issue Since you have included addCallAdapterFactory(RxJavaCallAdapterFactory.create()), you are looking to use Observable's to manage your calls. In your interface, explicitly give the parameterized Observable instead of a Call --
code :
    Observable<String> loginUser(@Field("email") String email, @Field("password") String pass, @Field("secret") String secret, @Field("device_id") String deviceid, @Field("pub_key") String pubkey, @Field("device_name") String devicename);
Observable<String> status = service.loginUser(loginedt.getText().toString(), passwordedt.getText().toString(), secret, device_id, pub_key, device_name);
status.subscribe(/* onNext, onError, onComplete handlers */);
