J'essaie de résoudre un problème plus important lié à l'animation d'un fragment imbriqué. J'ai donc créé un projet distinct et j'essaie de le résoudre en modules.Pourquoi la visibilité change-t-elle avant/après l'insertion de fragments imbriqués
La première partie est sur la visibilité au sein de la childFragment
- J'ai essayé différents types de code et je ne sais pas pourquoi quand j'ajouter layoutReturn.setVisibility(View.INVISIBLE);
Le fragment parent est caché. Pourtant, lorsque j'ajoute cette ligne après l'insertion du fragment enfant:
@Override
public void onClick(View v) {
//layoutReturn.setVisibility(View.INVISIBLE);
FragmentManager childFrag = getFragmentManager();
FragmentTransaction childFragTrans = childFrag.beginTransaction();
addressCard_fragment addressCardChild = new addressCard_fragment();
childFragTrans.add(R.id.bottom_row_fragment_container, addressCardChild);
//childFragTrans.setCustomAnimations(R.animator.slide_in_card, R.animator.slide_out_card);
childFragTrans.commit();
Toast.makeText(getActivity().getBaseContext(), "yo", Toast.LENGTH_SHORT).show();
layoutReturn.setVisibility(View.INVISIBLE);
}
La modification n'a aucun effet. Le fragment parent reste visible, le Toast apparaît mais le childFragment
reste invisible. Toute aide serait grandement appréciée!
Activité principale:
public class MainActivity extends AppCompatActivity {
private topRow_fragment fragmentTopRow;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
fragmentTopRow = new topRow_fragment();
}
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.top_row_fragment_container, fragmentTopRow);
fragmentTransaction.commit();
}}
classe parentFragment:
public class topRow_fragment extends Fragment implements View.OnClickListener{
ImageButton btn;
View layoutReturn;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
layoutReturn = inflater.inflate(R.layout.firstrow_fragment, container, false);
btn = (ImageButton) layoutReturn.findViewById(R.id.imageLeft);
btn.setOnClickListener(this);
return layoutReturn;
}
@Override
public void onClick(View v) {
//layoutReturn.setVisibility(View.INVISIBLE);
FragmentManager childFrag = getFragmentManager();
FragmentTransaction childFragTrans = childFrag.beginTransaction();
addressCard_fragment addressCardChild = new addressCard_fragment();
childFragTrans.add(R.id.bottom_row_fragment_container, addressCardChild);
//childFragTrans.setCustomAnimations(R.animator.slide_in_card, R.animator.slide_out_card);
childFragTrans.commit();
Toast.makeText(getActivity().getBaseContext(), "yo", Toast.LENGTH_SHORT).show();
layoutReturn.setVisibility(View.INVISIBLE);
}}
classe childFragment est juste la méthode onCreateView typique.
Update01: Quand j'utilise getChildFragmentManager Je reçois une erreur énorme qui commence par 09-14 22:54:34.933 20795-20795/com.example.bryanjordan.nestedfragmentstest E/FragmentManager: No view found for id 0x7f0c0060 (com.example.bryanjordan.nestedfragmentstest:id/bottom_row_fragment_container) for fragment addressCard_fragment{7d09836 #0 id=0x7f0c0060}
et se résume à: java.lang.IllegalArgumentException: No view found for id 0x7f0c0060 (com.example.bryanjordan.nestedfragmentstest:id/bottom_row_fragment_container) for fragment addressCard_fragment{7d09836 #0 id=0x7f0c0060}
