Android 个人通讯录【安卓进化十四】
最近写数据库，我就自己写了个带密码的个人通讯录，感觉sqlite特别好用，和mysql，sqlserver都一样，真是简单的关系型数据库，注意：开启数据库，cursor后一定要记得关闭close（）掉，避免浪费资源。另外adapter的notifyDataSetChanged（）这个方法也特别好用，就是数据库更新的时候，调用一下，baseAdapter中的getview就会重新加载一遍，这样界面就会更新数据，而不用onCreate（）方法来更新，另外可以把notifyDataSetChanged（）方法写在onResume（）方法中，这样在两个activity跳转后按back 键也可以达到刷新界面的效果！
想要源码的可以留言，有问题可以留言，同时也欢迎指正我的纰漏；

程序启动后输入密码的界面： 第一次启动程序和点击修改密码界面：
点击确定，进入联系人列表界面： 点击menu菜单，有两个菜单键：
单击每一个列表进入修改界面： 长按每一个联系人弹dialog删除记录：
