MainActivity a 2 boutons et lorsque je clique sur les boutons, je veux que 2 fragments apparaissent dans la même page. Mais quand je clique sur son boutonMontContact, il apparaît, mais quand je clique sur le bouton PhoneContact, je écraser l'autre.Des fragments Android semblent transparents
MainActivity.java
public class MainActivity extends AppCompatActivity {
Button itsMeContact,phoneContact;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
itsMeContact= (Button) findViewById(R.id.its_me_contact);
phoneContact= (Button) findViewById(R.id.phone_contact);
itsMeContact.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
FragmentManager manager = getFragmentManager();
UserFragment userFragment = new UserFragment();
FragmentTransaction transaction = manager.beginTransaction();
transaction.add(R.id.frame_layout, userFragment, "userFragment");
transaction.commit();
}
});
phoneContact.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
FragmentManager manager = getFragmentManager();
FragmentB fragmentB = new FragmentB();
FragmentTransaction transaction = manager.beginTransaction();
transaction.add(R.id.frame_layout, fragmentB, "fragg");
transaction.commit();
}
});
}
}
UserFragment.java
public class UserFragment extends Fragment {
RecyclerView recyclerView ;
UserAdapter userAdapter ;
ArrayList<Person> arrayList ;
private LinearLayoutManager layoutManager;
Button itsMeContact,phoneContact;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.fragment_user,container,false);
recyclerView = view.findViewById(R.id.recycler_view);
itsMeContact= view.findViewById(R.id.its_me_contact);
layoutManager = new LinearLayoutManager(getActivity());
layoutManager.scrollToPosition(0);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
arrayList=new ArrayList<Person>();
initial();
return view;
}
private void initial() {
Factory.getInstance().user().enqueue(new Callback<List<User>>() {
@Override
public void onResponse(Call<List<User>> call, Response<List<User>> response) {
// textView.setText(response.body().get(0).name);
userAdapter= new UserAdapter(response.body(), getActivity());
recyclerView.setAdapter(userAdapter);
}
@Override
public void onFailure(Call<List<User>> call, Throwable t) {
}
});
}
}
FragmentB.java
public class FragmentB extends Fragment {
TextView textView;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.fragment_fragment_b,container,false);
textView=view.findViewById(R.id.textView);
textView.setText("naber");
return view;
}
}
Votre conseil important pour moi!
