Recycler View Sélection erronée Visualiser l'objet lors de l'exécution du multi-sélection

Question

J'ai implémenté une vue recycleur avec Multi Select en utilisant addOnItemTouchListener pour l'identifier et la sélectionner en utilisant le double-clic. Lorsque j'ai moins de 5 éléments dans la vue recycleur, Tout fonctionne bien mais quand j'ai plus de données, pour être exact quand la vue recycleur commence à recycler la vue, ma sélection devient folle et elle sélectionne différentes possitions.J'ai déconnecté pour voir la position de clic, ceux-ci semblent être bons mais quelque chose ne va pas ce qui rend ma sélection wrong.I'm nouvelle à la programmation et à l'application android development.Can quelqu'un prendre beaucoup à cela et me aider s'il vous plaît, Voici mon code

ma classe adaptateur

Answer 1

Vous faites plus de la manipulation de la vue dans auditeur Onclick, vous devez déplacer que vous l'adaptateur onBindView, car même si vous définissez dans l'écouteur Onclick, il va modifier lorsque l'utilisateur défile.

Je ne donne pas la manipulation complète de la vue, je donne juste l'indice comment nous devrions faire.

@Override 
public void onBindViewHolder(final ContactHolder holder, int position) { 
    pos = position; 
    final Contact contact = contactList.get(pos); 

    holder.colg.setText(contact.getColg()); 
    holder.name.setText(contact.getName()); 
    holder.job.setText(contact.getJob()); 


    if (contact.getImage() != null) 
     holder.img.setImageBitmap(Utility.getPhoto(contact.getImage())); 


    if (multiselect_list.contains(contactArrayList.get(position))) { // May be you should check form your fragment or actvity using listeners 
     holder.mentee.setBackgroundColor(ContextCompat.getColor(ContactsActivity.this, R.color.colorPrimary)); 
     holder.participant.setBackgroundColor(ContextCompat.getColor(ContactsActivity.this, R.color.colorPrimary)); 

     holder.mentee.setVisibility(View.VISIBLE); 
     holder.participant.setVisibility(View.VISIBLE); 
    } else { 

     holder.mentee.setVisibility(View.GONE); 
     holder.participant.setVisibility(View.GONE); 
    } 

} 

Answer 2

ajouter boolena tableau

dans l'esprit initialize constructeur de votre arraylist.

itemcheck = new boolean[feedItemList.size()]; 

chèque porte-Bindview comme celui-ci

if(itemcheck[position]==true){ 
    holder.row_linearlayout.setBackgroundColor(Color.parseColor("#b7c5ea")); 
     }else { 
      holder.row_linearlayout.setBackgroundColor(0xFFFFFFFF); 
      //holder.row_linearlayout.setBackgroundResource(R.drawable.blurback); 
     } 

et perspectices définir ou faux onclick de votre relativelayout au lieu de tout controle autre controle.

holder.row_linearlayout.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        LinearLayout Lout = (LinearLayout) v.findViewById(R.id.selectlinear); 
        if(model.isSelected()){ 
         Lout.setBackgroundColor(0xFFFFFFFF); 
         itemcheck[position]=false; 
         //get all other controle value here 
        }else{ 

         Lout.setBackgroundColor(Color.parseColor("#b7c5ea")); 
         itemcheck[position]=true;  
         //get all other controle value here     
        } 
       } 
      });
