實現OnClickListener動態創建ExpandableListView與在Android中具有Radiobuttons的項目

Question

當一個標題的單選按鈕被選中時，其他單選按鈕也被自己檢查。並擴大所有和刷屏幕的單選按鈕標題正在交換或轉移。 請幫助如何管理動態製作的形式與許多單選按鈕選項。在我的情況下，窗體是在可擴展列表視圖。任何幫助將不勝感激。

public class ExpandableListAdapter extends BaseExpandableListAdapter implements ExpandableListView.OnGroupExpandListener{ 
public Context context; 
private List<String> listDataHeader; 
private HashMap<String,List<String>> listHashMap;

@Override

這是因爲單選按鈕的創建是有問題的。如果我會動態創建單選按鈕，我會做一些如下，

final RadioButton[] rb; 
//You can create a new radio group  
//RadioGroup rg = new RadioGroup(this.context); //create the RadioGroup 
// Or use from your xml 
    RadioGroup radioGroup = (RadioGroup) convertView.findViewById(R.id.radioGroup); 

radioGroup.setOrientation(RadioGroup.HORIZONTAL);//or RadioGroup.VERTICAL 
    for(int i=0; i < options.size(); i++){ 
     rb[i] = new RadioButton(this.context); 
     radioGroup.addView(rb[i]); //the RadioButtons are added to the radioGroup 
     rb[i].setText(options.get(k).getCp_value()); 
    } 
// if you added new radio group  
//convertView.addView(rg);//you add the whole RadioGroup to the layout, I suppose convertView is a layout view 

radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() 
     { 
      @Override 
      public void onCheckedChanged(RadioGroup group, int checkedId) { 
       // checkedId is the RadioButton selected 
       Toast.makeText(context, "okay", Toast.LENGTH_SHORT).show(); 
      } 
     });
