对于ListView的ArrayAdapter重写

listTag是标题；

class MyAdapter extends ArrayAdapter<String>
    {

     public MyAdapter(Context context, int textViewResourceId,
       List<String> objects) {
      super(context, textViewResourceId, objects);
      // TODO Auto-generated constructor stub
     }

     @Override
     public View getView(int position, View convertView, ViewGroup parent) {
      // TODO Auto-generated method stub
      
      
       View view = convertView; 
              //根据标签类型加载不通的布局模板  
                  if(listTag.contains(getItem(position))){ 
                     //如果是标签项 
                      view = LayoutInflater.from(getContext()).inflate(R.layout.group_list_item_tag, null); 
                  }else{ 
                     //否则就是数据项 
                      view = LayoutInflater.from(getContext()).inflate(R.layout.group_list_item, null); 
                 } 
               //显示名称 
               TextView textView = (TextView) view.findViewById(R.id.group_list_item_text); 
                  textView.setText(getItem(position)); 
                 //返回重写的view 
                 return view;
      
      
     }

     @Override
     public boolean areAllItemsEnabled() {
      // TODO Auto-generated method stub
      return super.areAllItemsEnabled();
     }

     @Override
     public boolean isEnabled(int position) {
      // TODO Auto-generated method stub
      return !listTag.contains(getItem(position));
     }
     
     
     
     
     
    }
