Кастинг RadioButton to ViewGroup

Question

Я получаю исключение classcasting, которое заявляет, что RadioButton не может быть передан в ViewGroup при переходе от активности к фрагменту, нажав на RadioButton. Любые предложения, пожалуйста и спасибо?

@Override 
     //protected void onCreate(Bundle savedInstanceState, ViewGroup container){ 
     protected void onCreate(Bundle savedInstanceState) { 

     Log.v("Main.class", "Main.class"); 

     super.onCreate(savedInstanceState); 
     setContentView(R.layout.button_tabs); 
     viewPager = (ViewPager) findViewById(R.id.pager); 
     mAdapter = new CustomButtonTabs(getSupportFragmentManager()); 
     viewPager.setAdapter(mAdapter); 

     radioFeatures = (RadioButton) findViewById(R.id.radioFeatures); 
     radioFeatures.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View vi) { 
       Log.v("radioFeatures selected", "radioFeatures selected");

       android.support.v4.app.FragmentTransaction fragTransaction = getSupportFragmentManager().beginTransaction();

       fragTransaction.commit(); 
       Log.v("endofmain-features", "endofmain-features");

to the following of FeaturesFragment: 

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

      Log.v("FeaturesFragment", "FeaturesFragment"); 

      // View v = (View) inflater.inflate(R.layout.carfeatures_list, container, false); 
      View v = inflater.inflate(R.layout.carfeatures_list, null); 
      ListView lv = (ListView) v.findViewById(android.R.id.list); 

      adapter = new CustomListViewAdapter(carFeaturesList, R.layout.carfeatures_list, super.getActivity()); 
      lv.setAdapter(adapter); 
      v.findViewById(R.id.featureslist); 

      //Listview on item click listener 
      lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { 

       @Override 
       public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 

        //Gets values from selected ListItem 

        String car_features = ((TextView) view.findViewById(R.id.car_features)).getText().toString(); 
        //Log.v("onCreate-car_features", car_features.toString()); 

        String carfeatures_id = ((TextView) view.findViewById(R.id.carfeatures_id)).getText().toString(); 
        //Log.v("onCreate-carfeatures_id", carfeatures_id.toString()); 

        String model_id = ((TextView) view.findViewById(R.id.model_id)).getText().toString(); 
        //Log.v("onCreate-model_id", model_id.toString()); 

        String carfeatures_desc = ((TextView) view.findViewById(R.id.carfeatures_desc)).getText().toString(); 
        //Log.v("onCreate-carfeats_desc", carfeatures_desc.toString()); 

        Boolean b = Boolean.valueOf(TAG_CARID); 
        if (b == true) { 
         view.setBackgroundColor(Color.GREEN); 
        } 

        //Colors the selected listview item 
        if (previouslySelectedItem != null) { 
         previouslySelectedItem.setBackgroundColor(Color.TRANSPARENT); 
         Log.v("previouslySelectedItem", "!=null"); 
         Log.v("position", Integer.toString(position)); 
        } 

        view.setBackgroundColor(Color.GREEN); 
        Log.v("position", Integer.toString(position)); 
        Log.v("outofif-view", view.toString()); 
        previouslySelectedItem = view; 
       } 
      }); 

      //Calls async task to get json 
      new GetCarFeatures().execute(); 

      Log.v("return called-Features", "return called"); 
      // Log.v("container-features", container.toString()); 
      return v; 
     } 

Answer 1

Это потому, что RadioButton не вытекает из ViewGroup ..

java.lang.Object

↳ android.view.View

↳ android.widget.TextView

↳ android.widget.Button

↳ android.widget.CompoundButton

↳ android.widget.RadioButton

Вот эти документы, показывающие наследование: http://developer.android.com/reference/android/widget/RadioButton.html

Вместо переходящие в R.id.radioFeatures к fragTransaction.replace вы должны пройти в id макета, который содержит RadioButton.
