android.content.res.Resources RadioGroupの$ NotFoundException

Question

RadioGroupというダイアログを作成したいと思います。ダイアログを開くときにアプリがクラッシュし、アラートダイアログが表示されません。私はRadioGroupとの対話を作成する方法です：

private void showRadioButtonDialog() { 

    final Dialog dialog = new Dialog(GenerateRaportActivity.this); 
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    dialog.setContentView(R.layout.radiobutton_dialog); 
    List<String> stringList = new ArrayList<>(); 
    for (int i = 0; i < 5; i++) { 
     stringList.add("RadioButton " + (i + 1)); 
    } 
    RadioGroup rg = (RadioGroup) dialog.findViewById(R.id.radio_group); 

    for (int i = 0; i < stringList.size(); i++) { 
     RadioButton rb = new RadioButton(GenerateRaportActivity.this); 
     rb.setText(stringList.get(i)); 
     rg.addView(rb); 
    } 
    dialog.show(); 
} 

をそして私は、私がこれを参照してください。このダイアログを表示しようとすると：

    android:layout_width="match_parent" 
    android:layout_height="match_parent"

のためにこれを使用してみてください例：

RadioGroup dynamicRadiogroup = new RadioGroup(MainActivity.this); 
RadioButton radiobutton1 = new RadioButton(MainActivity.this); 
RadioButton radiobutton2 = new RadioButton(MainActivity.this); 
RadioButton radiobutton3 = new RadioButton(MainActivity.this); 
RelativeLayout relativelayout = 
        (RelativeLayout)findViewById(R.id.relativelayout1); 

radiobutton1.setText("Android"); 
radiobutton2.setText("PHP"); 
radiobutton3.setText("WordPress"); 

dynamicRadiogroup.addView(radiobutton1); 
dynamicRadiogroup.addView(radiobutton2); 
dynamicRadiogroup.addView(radiobutton3); 

RelativeLayout.LayoutParams layoutparams = new RelativeLayout.LayoutParams 
(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT); 
dynamicRadiogroup.setLayoutParams(layoutparams); 
relativelayout.addView(dynamicRadiogroup);
