checkbox не работает должным образом в childview of ExpandableListview android

Question

В моем ExpandableListview, я использую Imageview и Checkbox для childview, который напоминает изображение формы и имя.

Когда я отмечаю checkbox конкретного дочернего элемента, другой дочерний элемент также получает галочку после прокрутки измененных изменений состояния.

Мне нужно было выбрать несколько значений.

public class ExpandableListAdapter extends BaseExpandableListAdapter { 

    private static final int[] EMPTY_STATE_SET = {}; 
    private static final int[] GROUP_EXPANDED_STATE_SET = 
      {android.R.attr.state_expanded}; 
    private static final int[][] GROUP_STATE_SETS = { 
     EMPTY_STATE_SET, // 0 
     GROUP_EXPANDED_STATE_SET // 1 
    }; 
    private Context _context; 
    private List<String> _listDataHeader; // header titles 
    // child data in format of header title, child title 
    private HashMap<String, List<String>> _listDataChild; 

    private ArrayList<Boolean> itemChecked = new ArrayList<Boolean>(); 
    private boolean[] itemCheckedBoolean = new boolean[100]; 



    Bitmap bmp; 
    LayoutInflater infalInflater; 


    ImageLoader imageLoader; 

    public ExpandableListAdapter(Context context, List<String> listDataHeader, HashMap<String, List<String>> listChildData) { 
     this._context = context; 
     this._listDataHeader = listDataHeader; 
     this._listDataChild = listChildData; 
     infalInflater = (LayoutInflater) this._context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();  
     StrictMode.setThreadPolicy(policy); 

     imageLoader=new ImageLoader(_context); 

     for (int i = 0; i < SearchWhiteDiamondsActivity.shape_list.size(); i++) { 
      itemChecked.add(i, false); 
     } 
    } 

    @Override 
    public Object getChild(int groupPosition, int childPosititon) { 

     return this._listDataChild.get(this._listDataHeader.get(groupPosition)) 
       .get(childPosititon); 
    } 

    @Override 
    public long getChildId(int groupPosition, int childPosition) { 
     return childPosition; 
    } 

    @Override 
    public View getChildView(int groupPosition, final int childPosition, 
      boolean isLastChild, View convertView, ViewGroup parent) { 

     String childText = (String) getChild(groupPosition, childPosition); 
     Log.e("_childText", "karjeevch "+childText); 


     int itemType = getChildType(groupPosition,childPosition);  


     ViewHolder viewHolder = null; 
     switch (itemType) { 

     case 0: 
      viewHolder = null; 
      if (convertView==null) { 

       viewHolder=new ViewHolder();     
       convertView = infalInflater.inflate(R.layout.list_child_shape, null); 
       viewHolder.shape_name = (CheckBox) convertView.findViewById(R.id.shape_chk_box); 
       //viewHolder.shape_name = (TextView) convertView.findViewById(R.id.shape_chk_box); 
       viewHolder.img_shape_icon=(ImageView)convertView.findViewById(R.id.img_shape);     


       imageLoader.DisplayImage("http://rosycontact.com/shashvat/images/"+childText.toLowerCase()+".png", viewHolder.img_shape_icon);     
       Log.e("shape", "karjeevshp "+childText); 
       viewHolder.shape_name.setText(childText); 
       convertView.setTag(viewHolder);    

       final CheckBox shape_name_temp=viewHolder.shape_name; 
       //final TextView shape_name_temp=viewHolder.shape_name; 



       viewHolder.shape_name.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 

        @Override 
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
         // TODO Auto-generated method stub 

         int id=buttonView.getId(); 
         if (id==R.id.shape_chk_box) { 

          if (shape_name_temp.isChecked()==true) { 

           String shape_str=shape_name_temp.getText().toString(); 
           All_link.SHAPE_LIST.add(shape_str); 
           Toast.makeText(_context, shape_name_temp.getText().toString(), Toast.LENGTH_SHORT).show(); 
           Log.e("chk_shape", "karjeevch "+shape_name_temp.getText().toString()); 
           itemChecked.set(childPosition, true); 
          } 
          else{ 
           String shape_str=shape_name_temp.getText().toString(); 
           All_link.SHAPE_LIST.remove(shape_str);        
           itemChecked.set(childPosition, false); 
          } 
         }                       
        } 
       });                  
      } 
      else{ 
       //viewHolder=new ViewHolder(); 
       viewHolder=(ViewHolder)convertView.getTag(); 
       imageLoader.DisplayImage("http://rosycontact.com/shashvat/images/"+childText.toLowerCase()+".png", viewHolder.img_shape_icon);            
       viewHolder.shape_name.setText(childText);        
       convertView.setTag(viewHolder);        
      } 
      return convertView;

сохранить состояние флажка ....

viewHolder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 

      @Override 
      public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
       int getPosition = (Integer) buttonView.getTag(); // Here we get the position that we have set for the checkbox using setTag. 
       list.get(getPosition).setSelected(buttonView.isChecked()); // Set the value of checkbox to maintain its state. 
      } 
     });
