上滾動列表視圖

Question

微調值上滾動列表視圖的變化，例如，如果我選擇不在第一位置，從我的微調OK，然後向下滾動，回到頂部，微調微調數值變化值自動在零位置意味着在OK。這裏是我的Adapter類，列表視圖中的數據是動態的（變化的）。下面

代碼：

public CustomAdapter(Context context, int resource, 
      ArrayList<CustomerDetails> objects) { 
     super(context, resource, objects); 
     vi = (LayoutInflater) context 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     Resource = resource; 
     list = objects; 
    } 

    public View getView(final int modelPosition, View convertView, 
      ViewGroup parent) { 

     View v = convertView; 
     if (v == null) { 
      holder = new ViewHolder(); 
      v = vi.inflate(Resource, null); 

      java.util.List<String> options = new java.util.ArrayList<String>(); 

      options.add("Ok"); 
      options.add("Not Ok"); 
      options.add("Not Recieved"); 

      holder.spinner1 = (Spinner) v.findViewById(R.id.spinner1); 
      holder.name = (TextView) v.findViewById(R.id.name); 

      ArrayAdapter<String> adapter = new ArrayAdapter<String>(
        getContext(), android.R.layout.simple_spinner_item, 
        options); 
      adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
      holder.spinner1.setAdapter(adapter);     

      if (myMap.containsKey(modelPosition)) { 
       holder.spinner1.setSelection(myMap.get(modelPosition)); 
      } 

      holder.spinner1.setTag(modelPosition); 
      holder.spinner1 
        .setOnItemSelectedListener(new OnItemSelectedListener() { 
         @Override 
         public void onItemSelected(AdapterView<?> parent, 
           View view, int position, long id) { 
          myMap.put(modelPosition, position); 

          if (position == 1) { 

           Status_fos = parent.getItemAtPosition(
             position).toString(); 

           db.updateMobileStatus(mobile_fos, 
             Status_fos); 

          } 
          if (position == 2) {       
           Status_fos = parent.getItemAtPosition(
             position).toString(); 

           db.updateMobileStatus(mobile_fos, 
             Status_fos); 
          } 
          if (position == 3) {  
           Status_fos = parent.getItemAtPosition(
             position).toString(); 

           db.updateMobileStatus(mobile_fos, 
             Status_fos); 
          } 

         } 

         @Override 
         public void onNothingSelected(AdapterView<?> parent) { 
          // TODO Auto-generated method stub 

         } 
        }); 
      v.setTag(holder); 
     } else { 
      holder = (ViewHolder) v.getTag(); 
     } 

     holder.name.setText(list.get(modelPosition).getMobile()); 
     mobile_fos = list.get(modelPosition) 
       .getMobile(); 

     return v; 
    } 

    class ViewHolder { 

     public Spinner spinner1; 
     public TextView name; 
     public TextView cid; 

    } 
}
