[안드로이드] 다중 CheckBox 에서 하나만 선택하게 하기

출처: https://stackoverflow.com/questions/32136029/how-can-i-select-only-one-checkbox-in-a-dynamic-view

Firstly, declare an ArrayList in the class:

ArrayList<CheckBox> mCheckBoxes = new ArrayList<CheckBox>();

Then in addGreetingToListView add every new checkbox to mCheckBoxes and modify the click listener of the checkbox:

checkBox.setTag(greetings);

mCheckBoxes.add(checkBox);
checkBox.setOnClickListener(new View.OnClickListener(){

        @Override
        public void onClick (View view) {

            if (((CheckBox) view).isChecked())
            {
                for (int i = 0; i < mCheckBoxes.size(); i++) {
                     if (mCheckBoxes.get(i) == view)
                         selected_position = i;
                     else 
                         mCheckBoxes.get(i).setChecked(false);
                }

            }
            else
            {
                selected_position=-1;
            }           
        }

    });
