Я получил ошибку при выполнении следующего кода

Error:The specified child already has a parent you must call removeView on the child's parent first

Кто-нибудь, пожалуйста, помогите мне в решении этого Кодекса:

RadioButton[] radiobutton = new RadioButton[5];
        RadioGroup radiogroup = new RadioGroup(this);
        for (int i = 0; i < 5; i++) {

            LinearLayout listmainLayout = (LinearLayout) findViewById(R.id.phonelist);
            // listmainLayout.setLayoutParams(new
            // ListView.LayoutParams(width,
            // height / 10));
            listmainLayout.setGravity(Gravity.CENTER_VERTICAL);
            RelativeLayout mainlistLayout = new RelativeLayout(
                    getApplicationContext());
            LinearLayout.LayoutParams mainlistLayoutParams = new LinearLayout.LayoutParams(
                    (int) (width * 0.85), LayoutParams.WRAP_CONTENT);
            mainlistLayout.setLayoutParams(mainlistLayoutParams);
            // mainlistLayout.setOrientation(LinearLayout.VERTICAL);
            mainlistLayout.setPadding((int) (0.03 * width), 0, 0, 0);
            LinearLayout.LayoutParams radiogroupparams = new LinearLayout.LayoutParams(
                    LinearLayout.LayoutParams.WRAP_CONTENT,
                    LinearLayout.LayoutParams.WRAP_CONTENT);
            radiogroup.setLayoutParams(radiogroupparams);
            radiobutton[i] = new RadioButton(this);
            radiobutton[i].setText(" " + ContactsActivity.phonetype.get(i)
                    + "    " + ContactsActivity.phone.get(i));
            radiobutton[i].setId(i + 100);
            radiogroup.removeView(radiobutton[i]);
            radiogroup.addView(radiobutton[i]);
            mainlistLayout.addView(radiogroup);

Мой logcat показывает:
