How to get verified radio button id created dynamically in android

Question

In my activity I create a dynamic radio group. I have some questions and answers in the Sqlite database, loading them in action, and then setting up in RadioGroup. This is working fine. But after that I want to get all the identifiers of the selected switch by the user in order to save them in the database. In general, we do something similar when we have an option ID:

            id1=rdgroup1.getCheckedRadioButtonId();
            que1=(RadioButton)findViewById(id1);
            ans1=que1.getId()+""; // so here I will get radio button ID.

So my questions are: how do I get the selected button id. Here is my code for dynamically creating a radio group.

     LinearLayout mLinearLayout = (LinearLayout) findViewById(R.id.linear1);
        c1=db.rawQuery("SELECT * FROM QueTable WHERE AgeGroup='10-20'", null);
        c1.moveToFirst();
        int i = c1.getCount();
        if(i > 0)
        {
            Log.w("START", "start");
            while (i > 0)
            {
                TextView title = new TextView(this);
                questions = c1.getString(1);
                title.setText(questions);
                title.setTextColor(Color.BLACK);
                mLinearLayout.addView(title);
                // create radio button

                answers=c1.getString(2);
                String[] answer = answers.split(",");
                rb = new RadioButton[5];
                rg = new RadioGroup(this);
                rg.setOrientation(RadioGroup.VERTICAL);

                int k = answer.length;

                for (int j = 0; j < k; j++)
                {
                    rb[j] = new RadioButton(this);
                    rg.addView(rb[j]);
                    rb[j].setText(answer[j]);
                }
                mLinearLayout.addView(rg);
                c1.moveToNext();
                i--;
            }
        }

Answer 3

, RadioButton Id

  for (int j = 0; j < k; j++)
            {
               RadioButton rb = new RadioButton(this);
                rb.setId(Somenumber + j)
                 rb[j] = rb;
                rg.addView(rb[j]);
                rb[j].setText(answer[j]);
            }
