Fragments in the TabLayout's ViewPager disappear on the second call

Come on!

I have an application that has a DrawerMenu (Menu Sliding), clicking on the Edit Profile item, calls a new Fragment ( EditFragment.class ), So, in this Fragment you have a TabLayout with a ViewPager , which contains 2 Tabs. Each Tab is populated with 1 Fragment ( EditGeraisFragment.class and EditSenhaFragment.class ).

When I first click on the Menu item, everything appears normally, it is called the EditFragment and the other 2 Fragments in the ViewPager normally appear, but when I click in another Menu item, and I click the Profile Edit Menu again , the Fragments in ViewPager no longer appear, / p>

Here are the codes:

Call the DrawerMenu .

.withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
                @Override
                public boolean onItemClick(View view, int position, IDrawerItem drawerItem) {
                    if (drawerItem != null) {

                        Fragment frag = null;

                        if(drawerItem.getIdentifier() == 1) {
                            frag = new PerfilFragment();
                            FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
                            ft.replace(R.id.rl_fragment_container, frag, "mainFrag");
                            ft.commit();

                            mToolbar.setTitle(((PrimaryDrawerItem) drawerItem).getName().toString());
                        } else if(drawerItem.getIdentifier() == 2) {
                            frag = new DepositosFragment();
                            FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
                            ft.replace(R.id.rl_fragment_container, frag, "mainFrag");
                            ft.commit();

                            mToolbar.setTitle(((PrimaryDrawerItem) drawerItem).getName().toString());
                        } else if(drawerItem.getIdentifier() == 3) {
                            frag = new EmprestimosFragment();
                            FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
                            ft.replace(R.id.rl_fragment_container, frag, "mainFrag");
                            ft.commit();

                            mToolbar.setTitle(((PrimaryDrawerItem) drawerItem).getName().toString());
                        } else if(drawerItem.getIdentifier() == 4) {
                            frag = new EditFragment();
                            FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
                            ft.replace(R.id.rl_fragment_container, frag, "mainFrag");
                            ft.commit();

                            mToolbar.setTitle(((PrimaryDrawerItem) drawerItem).getName().toString());
                        } else if(drawerItem.getIdentifier() == 7) {
                            PrefsUsuario.clearPrefs(mContext);

                            Intent abreLogin = new Intent(mContext, LoginActivity.class);
                            startActivity(abreLogin);
                            finish();
                        }
                    }

                    return false;
                }
            })

EditFragment.class

public class EditFragment extends Fragment {

private TabLayout tabLayout;
private ViewPager viewPager;
private ImageView profileImage, addPhoto;
private TextView profileName;
public static String photoImage, urlImageProfile;

• Below the 2 ViewPager Fragments

EditGeraisFragment.class

public class EditGeraisFragment extends Fragment {

private EditText textNome, textCPF, textEmail, textTelefone;
private Button botaoEnviarGerais;
private Context mContext;
//private static final String URLEnviarGerais = "http://www.caixinhadosmotoristas.com.br/validacao.php?acao=info-cliente";
//private RequestQueue requestQueue;
//private StringRequest request;
//private int idcliente;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,  Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_editgerais, container, false);

    textNome = (EditText) view.findViewById(R.id.textNome);
    textCPF = (EditText) view.findViewById(R.id.textCPF);

    return view;

    this.mContext = context;
    super.onAttach(mContext);
}

EditSenhaFragment.class

    return view;
}

@Override

    super.onAttach(mContext);
}
}

• Below is the ViewPager Adapter

EditAdapter.class

public class EditAdapter extends FragmentPagerAdapter {
private Context mContext;
private String[] titles = {"GERAIS", "SENHA"};

public EditAdapter(FragmentManager fm, Context context) {
    super(fm);
    mContext = context;
}

@Override
public Fragment getItem(int position) {
    Fragment frag = null;

    if(position==0) {
        frag = new EditGeraisFragment();
    } else if(position==1) {
        frag = new EditSenhaFragment();
    }

    Bundle bundle = new Bundle();
    bundle.putInt("position", position);

    frag.setArguments(bundle);

    return frag;
}

@Override
public int getCount() {
    return titles.length;
}

@Override
public CharSequence getPageTitle(int position) {
    return (titles[position]);
}
}
