012_04Thread+Handler实例应用之号码归属地查询

　　在Android的应用启动时，会创建一个主线程，主线程会创建一个消息队列来处理各种消息。当你创建子线程时，你可以在你的子线程中拿到父线程中创建的Handler 对象，就可以通过该对象向父线程的消息队列发送消息了。由于Android要求在UI线程中更新界面，因此，可以通过该方法在其它线程中更新界面。

　　每个handler 对应一个线程 thread ,  在子线程中 handler 发送的消息会进入到 Message Queue当中去，由 looper 再来分发给 Handler 处理。

 

 

　　我们创建的Service、Activity以及Broadcast均是一个主线程处理，这里我们可以理解为UI线程。但是在操作一些耗时操作时，比如I/O读写的大文件读写，数据库操作以及网络下载需要很长时间，为了不阻塞用户界面，出现ANR（Application Not Responding）的响应提示窗口，这个时候我们可以考虑使用Thread线程来解决。

查询效果图：

　　第一个按钮“查询”是使用HttpURLConnection+Thread+Handler+xml解析去获取;

　　第二个按钮“json查询”是使用HttpURLConnection+Thread+Handler+json解析去获取；

　　第三个按钮“使用Async-http-master xml查询”是使用AsyncHttpClient+AsyncHttpResponseHandler+xml解析去获取；

　　第四个按钮“使用Async-http-master json查询”是使用AsyncHttpClient+AsyncHttpResponseHandler+json解析去获取；
