/*
 * Create an ArrayList of Boolean Object to store the state of the each CheckBox
 * Initializes the ArrayList items to default value false, means no CheckBox is checked yet.
 * When you click on CheckBox. Set a check against Checked/Unchecked state and store that value in ArrayList.
 * Now set that position to CheckBox using setChecked() method.*/

Please add the following code and run it again and show me the logcat output:

 [...]
 @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            // TODO Auto-generated method stub
             if(position >= getCount()) {
                System.out.println("Error: position '"+position+"' is out of bounds in 'arrayList'");
                return;
             }
 [...]

Prevent duplicate list entries:

if(!myList.contains(objectToInsert) {
    myList.add(objectToInsert);
}
