如何将LineaLayout中的RadioButton放入RadioGroup中

Question

我有六个RadioButtons属于同一个问题，我需要把它们放在一些RadioGroup中。但是这些RadioButton在某些LinearLayouts中。我试图将一个RadioGroup放到每个RadioButton，但我不知道我需要做些什么让它工作。

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_gravity="bottom"
    android:layout_weight="1"
    android:orientation="vertical">

                        android:layout_weight="1"
                        android:orientation="horizontal">

                            <RadioButton

尝试此解决方案..

   class MyActivity extends Activity {

RadioButton _Rone, _Rtwo, _Rthree;

@Override
protected void onCreate(Bundle savedInstanceState) {

//after setContentView(.....)

    _Rone = (RadioButton) findViewById(R.id.radio_one);
    _Rtwo = (RadioButton) findViewById(R.id.radio_two);
    _Rthree = (RadioButton) findViewById(R.id.radio_three);

    _Rone.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            _Rone.setChecked(true);
            _Rtwo.setChecked(false);
            _Rthree.setChecked(false);
        }
    });

    _Rtwo.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            _Rone.setChecked(false);
            _Rtwo.setChecked(true);
            _Rthree.setChecked(false);
        }
    });

    _Rthree.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            _Rone.setChecked(false);
            _Rtwo.setChecked(false);
            _Rthree.setChecked(true);
        }
    });
 // do code here
}`

点击任意无线电按钮，对方的选择将重置。
