How to get the id of selected radio button in android?

Question

I am working on quiz application in android. We have created Select.java page which displays the questions and options(with radio buttons) from sqlite datab

Answer 1

Hmmm, just add one more member variable in UserBO to store selected answer.

Class UserBO {

private int userID;
private String userName;
private String question;
private String option1;
private String option2;
private String option3;

private int answerID;

//create getter and setters for above member variables
} 

then within onclick listener of Adapter class, do like as following

radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup radioGroup,
                int radioButtonID) {
        switch(radioButtonID) {
                case R.id.option1:
                       listItem.setAnswerID(1);
            break;
        case R.id.option2:
                listItem.setAnswerID(2);
            break;

                 }
        }
    });

then change your header constructor to receive userarraylist (which contains user details with answer)

ArrayList userList;
Header(Context context, AttributeSet attrs, ArrayList userALt) {
userList = userAL;
}

//on next button click

onclick() {
    for(UserBO userObj: userList) {
        if (userObj.getAnswerID != 0)
         Log.d("AnswerID", userObj.getAnswerID);
    }
}

it just like sudo code.. i hope this will help u..
