onClick不工作在片段

Question

由于某种原因onclick监听器没有响应点击以下片段中的事件，有什么想法为什么？

public class TestFragment extends Fragment{ 

    private TextView textViewOne; 
    private RadioButton radioButtonOne; 
    private RadioButton radioButtonTwo; 
    private RadioButton radioButtonThree; 
    private Spinner spinnerOne; 
    private RadioGroup radioGroupOne; 
      String buttonSelected; 
      Activity activity; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 

     activity = getActivity(); 


     View result=inflater.inflate(R.layout.tank_layout7, container, false); 

     textViewOne = (TextView) result.findViewById(R.id.textView1); 
     ratioButtonOne = (RadioButton) result.findViewById(R.id.radioButton1); 
     ratioButtonTwo = (RadioButton) result.findViewById(R.id.radioButton2); 
     ratioButtonThree = (RadioButton) result.findViewById(R.id.radioButton3); 
     spinnerOne = (Spinner) result.findViewById(R.id.spinner1); 
     radioGroupOne = (RadioGroup) result.findViewById(R.id.radio_group1); 

     radioGroupOne.setOnClickListener(new View.OnClickListener() { 

      public void onClick(View v) { 
       int checkedRadioButton = radioGroupOne.getCheckedRadioButtonId(); 
       switch(checkedRadioButton){ 
       case R.id.radioButton1: 
        buttonSelected = "button one selected"; 

        break; 
       case R.id.radioButton2: 
        buttonSelected = "button two selected"; 

       break;  
       case R.id.radioButton3: 
        buttonSelected = "button three selected"; 

       break; 
       default: 

       } 
       Toast.makeText(activity, "radio button selected " + buttonSelected, Toast.LENGTH_SHORT).show(); 
      } 
      }); 

     return(result); 

    } 

}

在RadioGroup使用的OnCheckedChangeListener，不是OnClickListener：

radioGroupOne.setOnCheckedChangeListener(new OnCheckedChangeListener(){ 
    @Override 
    public void onCheckedChanged(RadioGroup group, int checkedId) { 
     switch(checkedId){ 
      // Your code  
     } 
    } 
});
