在我以前的答案中编辑代码并将代码添加到我的先前答案中，当您在Android中进行编码时谁在帮助我，我将添加另一个解决方案，这次使用 http client

Instead edit and adding code to my previous answer who was helping when you coding in Android , i will add another solution , this time using http client

我不会在同一个文件中执行所有操作，但是我创建了两个文件，一个正在解析(可重用)，另一个正在使用第一个(客户端请求).

I din't do everything in the same file , but i created two files , one of parsing (reusable) and another one who is using the first one (client request) .
