ExpandViewListView的ChildView中的複選框

Question

在我的android應用程序中，我有一個ExpandableListView，每個組只有一個子項，其中包含一個複選框。我在設置複選框的值時遇到問題。

我從數據庫中檢索複選框的值，它在一個整數的ArrayList與值檢查，未經檢查分別

ArrayList<Integer> trustedList = new ArrayList<Integer>(); 

起初，我已經把所有的條目在數據庫中存儲0 & 1爲1.

爲ExpandableListView適配器類如下：

class DataAdapter extends BaseExpandableListAdapter { 

    private Context context; 
    LayoutInflater lat = getLayoutInflater(); 

    CheckBox cb; 

    public DataAdapter(Context context) { 
     // TODO Auto-generated constructor stub 
     this.context = context; 
    } 

@Override 
    public View getChildView(int group, int child, boolean arg2, View v, 
      ViewGroup arg4) { 
     // TODO Auto-generated method stub 

     v = lat.inflate(R.layout.inflate_list, null); 
     cb = (CheckBox) v.findViewById(R.id.checkBox1); 

     if (trustedList.get(group) == 1) 
      cb.setChecked(true); 
     else 
      cb.setChecked(false); 

    return v; 
} 
} 

但我發現了未經檢查的數值F或複選框。此外，在檢查複選框並摺疊和擴展組時，我會再次取消選中複選框。

請有人可以幫助我？

class DataAdapter extends BaseExpandableListAdapter { 

    private Context context; 
    LayoutInflater lat = getLayoutInflater(); 

    CheckBox cb; 

    public DataAdapter(Context context) { 
     // TODO Auto-generated constructor stub 
     this.context = context; 
    } 

@Override 
    public View getChildView(int group, int child, boolean arg2, View v, 
      ViewGroup arg4) { 
     // TODO Auto-generated method stub 

     v = lat.inflate(R.layout.inflate_list, null); 
     cb = (CheckBox) v.findViewById(R.id.checkBox1); 

     if (trustedList.get(group) == 1) 
      cb.setChecked(true); 
     else 
      cb.setChecked(false); 
cb.setOnCheckChangeListener(new CheckchangeListener(group)); 

    return v; 
} 
class CheckchangeListener implements OnCheckedChangeListener { 
     private int position; 

     public CheckchangeListener(int position) { 
      // TODO Auto-generated constructor stub 

      this.position= position; 

     } 

     @Override 
     public void onCheckedChanged(CompoundButton buttonView, 
       boolean isChecked) { 
      // TODO Auto-generated method stub 
      if (isChecked) { 
       //updateyour list and database here 

      } else { 
       //updateyour list and database here 

      } 

     } 
    }
