谁说咱们攻城狮不能写出既幽默又能懂的博客呢,本人想推出一系列博文,可以给刚接触Android开发的做一个参考,也可以与接触Android已久的各路大神比较一下,本人喜欢交流,如果有写得不好的地方,欢迎大家指出.如果有更好的效果或者功能,希望大家多多指点,互相学习可以共同进步.
说了这么多,现在进入今天的猪蹄,<<暴走系列--高仿淘宝收货地址>>,有网购经验的同学应该对这个很熟悉,在淘宝的Android客户端里面,有一个功能是设置收货地址,不清楚的同学可以自己下载个淘宝客户端,自己添加一下看看.
本人一向喜欢贴图,这样有图有真相,才能说服每个人,废话不多说先上自己程序启动画面,然后运行界面,最后一张是淘宝客户端对照图.
图片震楼 
启动界面 
运行界面 
淘宝界面
淘宝客户端无法录屏所以这里只能上静态的,大家可以自己打开淘宝客户端看看.
下面进行详细的代码讲解:
(一)本人在程序启动的时候开了一条后台服务landDivideServeice,目的是为了将全国的省市县总共4,189条数据插入到手机数据库里面去,原本的数据是保存在7个txt里面的,由于放在txt里面,读取操作很不方便,所以我把它放到数据库,在后面的所属地区筛选很快就出来,这个比淘宝还快哦,不信你们可以试一下.
有个新的知识点就是landDivideServeice是继承IntentService的,不是直接继承Service的,IntentService是继承于Service并处理异步请求的一个类，在IntentService内有一个工作线程来处理耗时操作，启动IntentService的方式和启动传统Service一样，同时，当任务执行完后，IntentService会自动停止，而不需要我们去手动控制。
so

}
(二)剩下的主要是一些界面的切换跟数据的读取,只要思路正确是不会被搞混的.

(三)这个是选择好地址之后的界面,主要还是界面的转换跟焦点的获取
有时候setFocusable(true)跟setFocusableInTouchMode(true)并不能使控件获得焦点,要再之前加上一句requestFocus(),这样控件就可以获得焦点.
