Answer 1

Определить один Interface класс:

public Interface OnChckBoxClickListener 
{ 

public void onCheckBoxClick(int position, boolean isChecked); 
} 

После этого создать объект интерфейса адаптера, см следующий код:

adapter = new NavDrawerListAdapter(getApplicationContext(), 
      navDrawerItems, new OnCheckBoxClickLisener() 
{ 
public void OnCheckBoxClick(int position, boolean isChecked) 
{ 
//print here position and isChecked 
// also do here code what you want 
} 
}); 

После этого зарегистрированного слушателя в конструкторе адаптера:

public NavDrawerListAdapter(Context conext, ArrayList<NavDrawerItem> navDrawerItems, OnCheckBoxClickLisener listener) 
{ 
this.context = context; 
this.navDrawerItems = navDrawerItems; 
this.lisetner = listener; 
} 

Затем установите Слушатель в OnClickOfCheckBox в getView:

ch.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      boolean ans = ch.isChecked(); 
      //navDrawerItems.get(position).setCounterVisibility(ans); 
      listener.OnCheckBoxClick(position, ans); 
Toast.makeText(context,String.valueOf(ch.isChecked()),Toast.LENGTH_LONG).show(); 

     } 
    });
