急 android listview 点击button 改变editText值

我的listview item上有两个按钮 要求button点击 editText值加一，总共有三条数据，但是界面listview初始了以后第一行按钮点击了editText值不变，上下滚动一下再点击就可以了，上下滚动几次后，第三条上button点击会回填到第二行的edittext，值回填错乱，请高手指点啊~！~~这是自定义的adapter

    在线等啊！！！！！
      

  2.   

    第一行按钮点击了editText值不变
    ================
    这个是不是没有刷新的问题啊。
    你将TextView控件改为TextSwitcher控件试试。Whenever setText(CharSequence) is called, TextSwitcher animates the current text out and animates the new text in. 
      

  3.   

    打印的日志我看到，初始化后，第一行点击没反应是因为getView没有调用！按钮点击事件触发，
    TextView值加一了。就是因为没刷新，不知道为何，更诡异的是上下滑动两下，回填值就错乱了
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {}
