J'ai une liste qui est dynamique. J'ai utilisé this tutorial. Tout se charge correctement, mais quand je défile, mes en-têtes sont en panne et hors service. Mon code est légèrement différent du tutoriel; un texte sur la gauche à droite, et le centre à la place de l'image et deux vues de texte. La vue de liste est remplie à partir de Parse.com.ListView dynamique rupture après le défilement
Ceci est mon chat de journal.

Le LogCat dit que j'ai une erreur ici dans mon SeparatedListAdapter.java
@Override
public boolean isEnabled(int position) {
return (getItemViewType(position) != TYPE_SECTION_HEADER);
}
public View getView(int position, View convertView, ViewGroup parent)
{
int sectionnum = 0;
for (Object section : this.sections.keySet())
{
Adapter adapter = sections.get(section);
int size = adapter.getCount() + 1;
// check if position inside this section
<----//This is (SeparatedListAdapter.java:105) ----->
if (position == 0) return headers.getView(sectionnum, convertView, parent);
if (position < size) return adapter.getView(position - 1, convertView, parent);
// otherwise jump into next section
position -= size;
sectionnum++;
}
return null;
}
Le tutoriel j'ai suivi n'a pas donné beaucoup d'explications à cela et ce qu'il fait vraiment. Alors, comment puis-je résoudre ce problème pour afficher correctement avant et après le défilement?

Indiquez le code dans lequel vous utilisez (remplissez) votre adaptateur. – Szymon
Pour info, vous pourriez être intéressé par le code de projet [StickyListHeaders] (https://github.com/emilsjolander/StickyListHeaders) aussi, si celui-ci ne fonctionne pas pour vous ... – MiStr
J'ai essayé le StickyListHeaders, je aimé, mais il a fait plus que ce dont j'avais besoin. Je l'ai aimé bien. –
