Gingerbread uygulamasına Fragmanlar eklemek için Uyumluluk Paketi 4 revizyonunu kullanıyorum. Hiçbir hata kaydedildi, ancak Fragment artık ekranda gösterilmiyor (bir kez daha temizlemeye ve yöntemleri eklemeye başladım!). Alt Parça, "goHome" ve "goCart" gibi navigasyon yöntemlerimi ümitle kaplayacak ve tüm ekranlara yerleştirilecek.
Öğeyi düzenlerime eklemeyi denedim ve android.view için korkunç Classnotfound hatası aldı. Bu yaklaşımı kullanarak çok daha fazla kazandım.Fragment Etkinliğime nasıl bir Android Fragment ekleyebilirim?
Günlüğüm, Parçanın eklendiğini gösterir. İşte Fragman:
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;
Günlük mesajları yukarıda gösterilmektedir.
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();
}
İşte Fragment kullandığı bottom_nav.xml var: İşte Parçası ekleyerek Aktivite bu.
