Question

I am working on quiz application. For each question there are multiple options should be selected. For that I have used checkboxes. When check box is checked I am storing the checked id value in arraylist and if unchecked I am removing that id from the arraylist. Also before this I am adding the number of answers for each question in the arraylist and in the next button click I am adding an “|”(or) symbol to differentiate the questions.

So for example 3 questions are displayed….then my arraylist contains

Now for the first question I selected 3 option, for second question I selected 4 options and for third question I didnt select any of the option. So for third question only the number of correct answers and the | symbol is displayed. But now my problem if none of the checkboxes are selected I want to pass a value in the arraylist. How can I do that? Please help me regarding this….Struggling for this since 3 days….

My Code:

cbs[k].setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {

        if (((CheckBox) v).isChecked()) {

            selchkboxlist.add(Integer.toString(v
                    .getId()));

            System.out.println("chkboxlist size"
                    + selchkboxlist.size());

        } 
        else
        {

            selchkboxlist.remove(Integer.toString(v
                    .getId()));
            System.out
                    .println("after delete chkboxlist size"
                            + selchkboxlist.size());
            }

    }
}); 

Will be thankful in advance

Then before going to next question check your arraylist..

 int k=yourlist.length();
  if(Integer.parseInt(yourlist.get(k-2))<=4){
 //then it is number of answers and no check box has been checked..
  arraylist.set(k-1,new String("some value to indicate nothing"));
  arraylist.add("|");

   }
