Korzystam z Pakietu zgodności, wersja 4, aby dodać Fragmenty do mojej aplikacji Gingerbread. Żadne błędy nie są rejestrowane, jednak Fragment nie pojawia się już na ekranie (zrobił to kiedyś, zanim zacząłem go czyścić i dodawać metody!). Dolny Fragment ma nadzieję, że moje metody nawigacji, takie jak "goHome" i "goCart", zostaną umieszczone na wszystkich ekranach.
Próbowałem dodać element do moich układów i otrzymałem przerażający błąd Classnotfound dla android.view. Z tego podejścia skorzystałem znacznie dalej.Jak dodać Fragment Androida do mojej FragmentActivity?
Mój log pokazuje fragment został dodany. Oto fragment:
public class BottomFragment extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View v = inflater.inflate(R.layout.bottom_nav, container, false);
Log.v("BottomFragment","onCreate after inflate");
/*
ImageView find_img = (ImageView)v.findViewById(R.id.bottom_find_image);
find_img.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.v("BottomFragment.OnClickListener"," with Find clicked");
findRegistry();
}
});
*/
// Inflate the layout for this fragment
return v;
Wiadomości dziennika pokazane powyżej. Oto aktywny dodanie fragmentu:
public class StartActivity extends FragmentActivity {
public static Context appContext;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.find_main);
appContext = getApplicationContext();
// Create new fragment and transaction
BottomFragment newFragment = new BottomFragment();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.add(R.id.frame_bottom_frag, newFragment);
// Commit the transaction
transaction.commit();
}
Oto bottom_nav.xml wykorzystywane przez fragment.
