listview刷新与内部控件的监听

困扰我多日的关于Android中的listview问题，今天终于完全解决了，首先讲一下到底遇到的是什么问题：（1）点击listview的item布局中的ImageButton按钮来获取相应的Textview的内容（2）通过点击上一问题中的按钮来更新listview。这个跟新listview网上大部分人推荐使用adapter.notifyDataSetChanged();//刷新适配器；

其实关于具体的listview原理我也不是太清楚，在这里只是记录一下解决问题的方法与相应的代码，方便以后遇到同样的问题来此查阅。

其实上面的两个问题合并起来也就是一个问题。

private void loadListView(){
     
     adapter = new SimpleAdapter(this,getData(),R.layout.today_item,
                          new String[]{"id","detail"},new int[]{R.id.taskid,R.id.detailid}){
        public View getView(final int position, View convertView,ViewGroup parent) {
            final int index = position;
             View v= super.getView(position, convertView, parent);
               ImageButton btn=(ImageButton)v.findViewById(R.id.tasksubmit);
               btn.setTag(position);
               //id=(TextView)v.findViewById(R.id.taskid);
               btn.setOnClickListener(new OnClickListener() {
                    public void onClick(View v) {
                        //Toast.makeText(getApplicationContext(), "测试提交按钮", Toast.LENGTH_LONG).show();
                          
Toast.makeText(getApplicationContext(), "单击我了"+list.get(position).get("id").toString(), 1).show();//通过position来获取TextView的内容，需要重写getView方法
                         
                        //list.
                        dialog(index);
                         
                    }
               }); 
        //此监听留作扩充功能使用。    
        v.setOnClickListener(new OnClickListener() {
             
            public void onClick(View v) {
             
            }
        });    
            return v;
        }
    };
     
     
        listView.setAdapter(adapter);
 }
 private  List<Map<String, Object>> getData() {
     i++;
     System.out.println("第"+i+"次");
     list = new ArrayList<Map<String, Object>>();
     /*for(int i=0;i<getorder.size();i++)
     {
         Map<String, Object> map = new HashMap<String, Object>();
          map.put("id",getorder.get(i));
          map.put("detail", detail.get(i));
             list.add(map);
     }*/
        
     Map<String, Object> map = new HashMap<String, Object>();
