Ho il seguente adattatore nel mio Activity. Ho impostato uno su GroupView che quando toccato controllerà/deselezionerà le viste secondarie (che hanno anche un CheckBox).ExpandableListView groupView checkbox deselezionare altre groupviews
Lo stato di CheckBox(true or false) viene memorizzato nel DB e inizialmente impostato su true/checked. Le caselle di controllo sono inizialmente selezionate.
C'è un comportamento strano quando tocco un GroupCheckbox, deseleziona anche la casella di controllo che non fa parte dello GroupView che è stato toccato.
Quindi, ad esempio, se ho 5 GroupViews e ogni GroupView ha 5 figli. Se deseleziono il 1 GroupView , deseleziona tutti i suoi figli ma anche il 3 ° GroupViewCheckBox ei suoi figli.
Ci sono idee perché?
[Modifica 1]
Ho cancellato frammenti di codice precedenti, sto iniziando una taglia. Il codice è cambiato rispetto all'originale poiché Ankit Kumar mi ha aiutato con il patter di Viewholder nel metodo getGroupView. Deseleziona ancora più caselle di controllo di groupview quando viene toccata una sola casella di controllo. il DB di supporto ha tutti gli stati delle caselle spuntate come true per iniziare.
Sembra che la vista non sia sincronizzata con il DB. Ho disconnesso le dichiarazioni che dimostrano che lo stato di tutte le checkbox è vero per iniziare.
C'è un modo per fare solo la casella di controllo che l'utente tocca deseleziona senza influenzare le altre caselle?

Usa ViewHolder per l'inizializzazione e l'utilizzo delle vostre opinioni nel adattatore – Android
stai affrontando problema durante lo scorrimento? –
@AnkitKumar Un viewHolder accelera la reattività dell'adattatore non dovendo cercare gli oggetti ma questo spiega perché quando tocco una casella di controllo GroupView viene selezionata anche un'altra vista di gruppo? – turtleboy
