如何把放在RadioGroup裏面的LineaLayout中的RadioButton

Question

我有六個RadioButton屬於同一個問題，我需要把它們放在RadioGroup中。但是這些RadioButton在某些LinearLayouts中。我試圖把一個RadioGroup放到每個RadioButton上，但我不知道我需要爲它做些什麼。

<LinearLayout

嘗試這種解決方案..

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 
}` 

通過點擊按鈕anyradio其他的選擇將復位。
