运行效果图：

需要用到四个lib包：解析json gson包，从网络地址解析json数据成String字符串的异步网络解析工具AsyncHttpClient，等

解析网络json数据，模拟美团界面显示相关内容就给大家介绍到这里，希望对大家有所帮助。

接着给大家介绍模拟json数据解析格式

// String response =
// "{\"code\":\"1\",\"desc\":\"success\",\"data\":{\"showCount\":\"10\",\"totalCount\":\"1\",\"totalPage\":\"1\",\"currPage\":\"1\",\"offset\":\"0\"},\"apps\":["
