je veux les données montrent à la liste dépensé et quand je clique sur le bouton i obtenir tout élément vérifié .

Answer 1

le problème est cette méthode:

public int getChildrenCount(int groupPosition) { 
     return dFoStructs.get(groupPosition).size(); 
} 

dFoStructs a exactement un élément. Si vous essayez d'obtenir la valeur avec l'index 1, il doit conduire à ArrayIndexOutOfBoundsException car le Array commence à la position 0.

si le comptage des groupPosition commence à la position 1, vous devez veiller à ce que vous réduisez l'indice comme celui-ci:

public int getChildrenCount(int groupPosition) { 
      return dFoStructs.get(groupPosition-1).size(); 
}
