Comment implémenter une ligne listview personnalisée avec des boutons?

Question

J'ai un ExpandableListView que je veux remplir avec mes vues personnalisées du type NoteView. NoteView étend LinearLayout et contient deux boutons et une case à cocher. J'ai presque tout fonctionnant, les NoteView sont remplis avec des données de support, les listes sont remplies, et les boutons sont cliquables et accomplissent les tâches requises.

Le problème est que ExpandableListView ne répond plus du tout aux événements click/longclick/keypress (autres que la sélection d'éléments de liste avec trackball/DPAD). J'ai remplacé ma vue personnalisée par un TextView standard et les événements tactiles ont repris leur cours normal. Il est donc presque certain que je fais quelque chose de mal avec ma vue personnalisée ou un paramètre ListView obscur que je néglige.

Voici mon code NoteView et ma mise en page XML. Qu'est-ce que je rate?

//Custom Note View 
public class NoteView extends LinearLayout{ 

    private CheckBox mCheckBox;

     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

Answer 1

J'ai eu un problème similaire qui happends lorsque l'utilisation d'une case à cocher est dans la mise en page des articles de ListView. S'il vous plaît vérifier si l'ajout de l'attribut: android: focusable = « false » à la définition de case à cocher vous aide aime:

<CheckBox android:id="@+id/noteViewCB" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:focusable="false" /> 

La question semble être que Android ne vous permet pas de sélectionner des éléments de liste qui ont éléments sur eux qui sont focalisables.

Best,
