Answer 1

finally i solved this issue :) where as globalInc is global variable with default value 0

holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() 
      {

            @Override
            public void onCheckedChanged(CompoundButton checkboxView, boolean isChecked) 
            {
                 myContacts c = (myContacts) checkboxView.getTag();

                 if(isChecked)
                 {
                     globalInc++;
                 }
                 else if(!isChecked)
                 {
                     globalInc--;
                 }
                 if(globalInc >= 4)// it will allow 3 checkboxes only
                 {
                     Toast.makeText(context, "Error = " + globalInc, Toast.LENGTH_LONG).show();
                     checkboxView.setChecked(false);
                     globalInc--;
                 }
                 else
                 {
                    c.setSelected(isChecked);
                 }
                 System.out.println(" ---------------    "+globalInc);
            }
        });
