1.使用Dialog实现复选功能并与后台数据通过Id绑定.

2.实现显示时默认选中项控制.

3.实现修改后保存,根据id保存.

4.数据库处理使用AHibernate1.1,详见:http://blog.csdn.net/lk_blog/article/details/8201449

单选按钮实例见上篇博客:http://blog.csdn.net/lk_blog/article/details/8515347

本示例效果图:

主要代码:

dialog.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="修改班级[五期提高班]内学生信息" />

    <Button
        android:id="@+id/btnModify"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="修改" />

</LinearLayout>
