Jeu de tag pour la case à cocher comme le nom que vous donnez à la Case aussi le tag pour cette case, puis vous pouvez accéder à l'onglet dans votre setOnClickListener

viewHolder.checkbox.setTag("Write here name");
viewHolder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
Model element = (Model) viewHolder.checkbox.getTag();  
element.setSelected(buttonView.isChecked());
Log.v("Checked Name",buttonview.getTag().toString());
}
});

si vous voulez savoir à quelle case à cocher a été (onu)est cochée, vous pouvez ainsi enregistrer un nouveau port d'écoute de l'instance pour chaque case à cocher.

    CheckBox one = (CheckBox)findViewById(R.id.checkBox1);
one.setOnClickListener(new OnClickListener() 
{
@Override
public void onClick(View v) 
{
Log.d(TAG,"I am checkbox 1!");
}
});
CheckBox two = (CheckBox)findViewById(R.id.checkBox2);
two.setOnClickListener(new OnClickListener() 
{
@Override
public void onClick(View v) 
{
Log.d(TAG,"I am checkbox 2!");
}
});
