TextView OnClickListener не работает во фрагментах

0 голосов
/ 05 сентября 2018

Итак, моя проблема, скажем, мы находимся в SignInFragment (Для навигации в SignInFragment, пусковая установка - это MainActivity внутри, которая откроет HomeFragment, тогда внутри HomeFragment есть код, если есть если пользователь не вошел в систему, он перейдет к SignInFragment), затем в SignInFragment появится TextView «У вас еще нет учетной записи? Зарегистрируйтесь здесь». Поэтому, когда я нажимаю, ничего не происходит. Надеюсь, вы понимаете.

Я добавлю другие фрагменты, чтобы легко понять поток моего приложения.

Вот коды для: MainActivity

import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    HomeActivity fragment = new HomeActivity();

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    ft.replace(R.id.container, fragment, fragment.getTag());
    ft.commit();

}

Вот коды для: HomeActivity

public class HomeActivity extends Fragment {

private static final String TAG = "HomeActivity";

TextView mWelcome;
Button btnSignout;

    mWelcome = view.findViewById(R.id.welcome);
    btnSignout = view.findViewById(R.id.btnSignOut);

    setupFirebaseAuth();

    //Firebase
    mAuth = FirebaseAuth.getInstance();

    btnSignout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            FragmentTransaction ft = getFragmentManager().beginTransaction();

        }

    return view;

Я думаю, что проблема с getFragmentManager(), при использовании фрагментов из v4.app.Fragment необходимо использовать getSupportFragmentManager()

Обновление:

Я только что понял, что вы начинаете новый фрагмент с фрагмента. Хотя это не очень хорошая практика, и вы всегда должны позволять своей родительской деятельности совершать фрагментные транзакции. Вы можете узнать больше здесь и здесь

Но сейчас вы можете получить ссылку на getSupportFragmentManager(), например: 

mToRegister.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        RegisterFragment fragment = new RegisterFragment();
        FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
        ft.replace(R.id.container, fragment, fragment.getTag());
        ft.commit();
    }
});
