| | =====Binding===== |
| | |
| | Il existe ''View binding'' et ''Data binding''. |
| | |
| | Si l'objectif est seulement de remplacer les ''findViewById'', il faut utiliser ''View binding'' car plus léger. |
| | |
| | Si l'objectif est également de maîtriser les données lors de la reconstruction d'un fragment, ''Data binding'' est nécessaire. |
| | |
| | ====View binding==== |
| | |
| | ====Data binding==== |
| | |
| | * Chargement du fragment |
| | |
| | <code java> |
| | @Override |
| | @Nullable |
| | public View onCreateView(@NonNull final LayoutInflater inflater, |
| | @Nullable final ViewGroup container, @Nullable final Bundle savedInstanceState) { |
| | super.onCreateView(inflater, container, savedInstanceState); |
| | |
| | binding = NameFragmentBinding.inflate(inflater, container, false); |
| | binding.setLifecycleOwner(getViewLifecycleOwner()); // Uniquement nécessaire si le binding est lié à un LiveData. |
| | |
| | return binding.getRoot(); |
| | } |
| | </code> |

| | ====Problèmes===== |
| | |
| | Si une ressource ne génère pas le binding, il faut entourer la ressource par ''<layout></layout>''. |
