Answer 1

1.尝试从onCreateView()调用方法configViews()并传递视图kf06_view作为参数。

2.实施View.OnClickListener处理button_kf06_back和button_kf06_next click事件。

更新您的K06_Away片段如下：

public class K06_Away extends Fragment implements View.OnClickListener { 

    protected Typeface tfLatoBold,tfLatoMedium,tfLatoRegular; 
    private Button button_kf06_back,button_kf06_next; 
    private TextView txtVw_kf06_resident_away; 
    private EditText edTxt_kf06_visiting_lastname; 
    private RadioGroup radioGp_kf06_resident_away; 
    List<RadioButton> radioButtons = new ArrayList<RadioButton>(); 

    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     View kf06_view = inflater.inflate(R.layout.k06_away, container, false); 

     // Init 
     configViews(kf06_view); 

     return kf06_view; 
    } 

    private void configViews(View view) { 
     button_kf06_back = (Button) view.findViewById(R.id.button_kf06_back); 
     button_kf06_next = (Button) view.findViewById(R.id.button_kf06_next); 
     txtVw_kf06_resident_away= (TextView) view.findViewById(R.id.txtVw_kf06_resident_away); 

     radioGp_kf06_resident_away = (RadioGroup) view.findViewById(R.id.radioGp_kf06_resident_away); 
     radioButtons.add((RadioButton) view.findViewById(R.id.radio_kf06_1_2_hours)); 
     radioButtons.add((RadioButton) view.findViewById(R.id.radio_kf06_halfday)); 
     radioButtons.add((RadioButton) view.findViewById(R.id.radio_kf06_allday)); 
     radioButtons.add((RadioButton) view.findViewById(R.id.radio_kf06_moreday)); 

     configClickListeners(); 
     radioButtonAction(); 
    } 

    @Override 
    public void onClick(View v) { 
     switch (v.getId()) { 
      case R.id.button_kf06_back: 
       // Do something... 
       break; 
      case R.id.button_kf06_next: 
       // Do something... 
       break; 
     } 
    } 

    private void configClickListeners() { 
     button_kf06_back.setOnClickListener(this); 
     button_kf06_next.setOnClickListener(this); 
    } 

    private void radioButtonAction(){ 
     for (RadioButton button : radioButtons){ 
      button.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){ 
       @Override 
       public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
        if (isChecked) processRadioButtonClick(buttonView); 
        String radio_Text = buttonView.getText().toString(); 
        int radio_Id = buttonView.getId(); 
        System.out.println("Selected the Radio:"+radio_Text+", Radio-Id:"+radio_Id); 
       } 
      }); 
     } 
    } 

    private void processRadioButtonClick(CompoundButton buttonView){ 
     for (RadioButton button : radioButtons){ 
      if (button != buttonView) button.setChecked(false); 
     } 
    } 
} 

Answer 2

RadioGroup中直接包含仅单选按钮，没有其他的布局，如果添加的LinearLayout里面RadioGroup中，它不是work.Directly使用outLineLayout在Radiogroup中添加Radiobuttons，它们将工作。
