Two radio buttons getting selected in Radio Group

Question

Two buttons getting selected in the radio group.
I do not know where I am getting wrong. Please help me out.

final RadioGroup rg=new RadioGroup(Survay_MainActivity.this);
rg.clearCheck();
rg.setId(Integer.valueOf(entry1.getKey()));  
Log.v("rg getid", "rg"+rg.getId());
for(int i =0;i<values.size();i++){
    // Create Button
    final RadioButton btn = new RadioButton(Survay_MainActivity.this);
    btn.setId(i);
    btn.setTextColor(Color.parseColor("#000000"));
    btn.setBackgroundColor(Color.TRANSPARENT);
    btn.setGravity(Gravity.LEFT);
    btn.setText(values.get(i));

    rg.addView(btn);
    btn.setLayoutParams(params);
    btn.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            JSONObject quesAns = new JSONObject();
            String ans=btn.getText().toString().trim();
            try {
                quesAns.put(String.valueOf(rg.getId()), ans);
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            jsonarray.put(quesAns);    
            Log.v("jsonarray", "jsonarray"+jsonarray);
        }
    });
}     
views.addView(rg);     

1) I am creating the RadioGroup out of the loop.

2) Adding radio button to the RadioGroup in the for loop

3) When the loop finishes the RadioGroup is added to the linerlayout.

You just need to change different ids for different radio button. There may be some id clash in gen file. Radio button1 : android:id="@+id/one Radio button2 : android:id="@+id/two" Radio button3 : android:id="@+id/three"

Hope this would help.
