I want to make a compare laptop function by using spinner as the selection list and show it in CardView. I have created 2 Spinner and 2 Cardview put them into a fragment since I using bottom navigation for the whole system. After I try the solution available in StackOverflow doesn't fit me to solve the problem.
here my firebase
here the comparefragment.java`
public class CompareFragment extends Fragment {
private Spinner spinner;
private Spinner spinner2;
private CardView card1, card2;
ImageView imageView1 , imageView2;
TextView text1,text2,text3,text4,text5,text6,text7,text8,ted1,ted2,ted3,ted4,ted5,ted6,ted7,ted8;
List<String> laptopname;
private DatabaseReference mDatabaseReference;
StorageReference StorageRef;
FirebaseHelper helper;
@Nullable
@Override
public View onCreateView(@Nullable LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle saveInstanceState) {
View view = inflater.inflate(R.layout.fragment_compare2, container, false);
spinner = (Spinner) view.findViewById(R.id.spinner);
spinner2 = (Spinner) view.findViewById(R.id.spinner2);
card1 = (CardView) view.findViewById(R.id.cv1);
card2 = (CardView) view.findViewById(R.id.cv2);
imageView1 = (ImageView)view.findViewById(R.id.imageView7);
imageView2 = (ImageView)view.findViewById(R.id.imageView8);
text1= (TextView)view.findViewById(R.id.laptopname);
text2= (TextView)view.findViewById(R.id.price);
text3= (TextView)view.findViewById(R.id.performance);
text4= (TextView)view.findViewById(R.id.graphic);
