ViewHolderHeader.header parce que c'est null!, Sur la liste Faites défiler vos vues d'élément de liste sont recyclés et votre détenteur pointant probablement à la mauvaise vue. override getItemViewType, pour refrence voir ceci http://stackoverflow.com/questions/13590627/android-listview-headers?rq=1 –

Merci, @RachitSolanki, je passe par le lien que vous avez suggéré mais c'est trop compliqué. Alors que je suis ce lien http://kyogs.blogspot.in/2014/06/the-use-of-getviewtypecount-and.html. Mais encore je reçois la même erreur. – Jay

@RachitSolanki J'ai mis à jour ma classe arrayadpater. Mais je reçois toujours la même erreur que précédemment. Erreur dans cette ligne "viewHolderHeader.txt_header.setText (state.getRegion());" – Jay

Lorsque vous enregistrez le viewHolderHeader dans l'étiquette que vous utilisez cette ligne de code.

convertView.setTag(viewHolderHeader);

mais lorsque vous récupérez le viewHolderHeader, vous utilisez une clé pour le renvoyer:

viewHolderHeader = (ViewHolderHeader) convertView.getTag(R.layout.section_header);

Je ne sais pas ce serait correspondre, vous devez utiliser la même clé dans la première ligne:

convertView.setTag(R.layout.section_header, viewHolderHeader);

Salut @Blundell selon vos suggestions listview défilement fonctionne bien. Mais maintenant, la case à cocher listview et les clics sur les boutons radio ne fonctionnent pas. Pouvez-vous s'il vous plaît m'aider dans ce domaine? – Jay

vous devriez marquer ceci comme une réponse correcte et ouvrir une nouvelle question – Blundell

Lorsque la vue revalorisés est avec mal type, la vue doit également être gonflée. Essayez aussi de combiner les 2 types de ViewHolder en 1.

Essayez ceci:

public class ABCArrayAdapter extends ArrayAdapter<ABCModel> {

}

    return this.selectedlocation.get(position).hashCode(); 
}
