Set-tag für checkbox wie der name, den Sie geben, um Markierungsfeld auch einstellen, dass es tag für das checkbox-dann können Sie auf der Registerkarte Zugriff in Ihrem 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());
 }
});

wenn Sie wissen möchten, welche checkbox wurde (un)überprüft, können Sie ebenso registrieren Sie eine neue listener-Instanz für jede checkbox.

    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!");
     }
});
