Problème de l'adaptateur RecyclerView

-3

J'ai un problème lors du chargement des données dans l'affichage de l'adaptateur de la vue de recyclage.Problème de l'adaptateur RecyclerView

J'ai deux Fragment en activité et le deuxième Fragment ai 3 vues de recyclage. Mais le problème est que j'ai un checkbox dans le support de vue brute, j'ai vérifié un de cela. quand je fais défiler vers le haut/bas alors que les données de recycleview réorganisent les données par défaut et toutes les cases à cocher sont à nouveau fausses.

J'ai utilisé set recycle (false) dans la méthode on bind mais ne fonctionne toujours pas.

S'il vous plaît envoyer votre code que vous avez essayé. –

... quel problème? –

Bonjour à tous, Merci pour vos commentaires et votre aide. J'ai résolu mon auto. Je modifie ma classe MODEL en plaçant une variable booléenne et en gérant cette variable à partir de la méthode onbind et en cliquant sur l'écouteur. – Jay

Vous devez maintenir l'état de chaque case en vous modèle de données à partir onCheckChangeListener de case à cocher toutes les positions WRT.

Ensuite, vous devez définir l'état de case à cocher dans la méthode onBind de l'adaptateur

La vue recycleur réutilise la vue OnBindViewHolder. Ainsi, lorsque les éléments sont défilés, la vue est recyclée à nouveau. Pour résoudre ce problème.

créer une variable globale pour stocker la position sur laquelle vous avez cliqué. Ensuite, à l'intérieur du viewholder, ajoutez clickListener et onClick stocke la position de l'élément cliqué.

public class ViewHolder extends RecyclerView.ViewHolder { 

    public ViewHolder(View v) { 
     super(v); 
     v.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       mItemSelected = getAdapterPosition(); 
       notifyDataSetChanged(); 

      } 
     }); 
    } 
}

Et à l'intérieur OnBindViewHolder,

@Override 
public void onBindViewHolder(final ViewHolder holder, final int position) { 

    if(mItemSelected==position){ 
     holder.status.setChecked(true)‌; 
    }else{ 
     holder.status.setChecked(false)‌; 
    } 
}
