        if (0 == data.my_index) {// my_index是代码是自定义的下标值
            _cell.y = 0;
        } else if (1 == data.my_index) {

}
 
this.list_view.array = this.mList_.task_info;// 更新数据源
// this.list_view.content.height = (this.mList_.task_info.length - 1) * 152 + 80 + (this.mList_.task_info.length - 1) * 10;// 动态改变大小
上面这段代码不生效。
