Android Xstream



第一次写博客，应该能看

一，什么是xstream

 

Xstream是将java对象和XML互相转换的第三方架包。

 

本文使用的xstream版本是1.4.7版本  【注：因xstream已经放入studio库中这里就不提供第三方包地址了】

 

废话不多说，代码是最好的解释：

 

MainActivity的xml布局就写了一个TextView， 很是简单我这里就不写了

 

 

MainActivity

 

 

 public class MainActivityextendsAppCompatActivity {
   <TfrxReportVersion="4.9.20"DotMatrixReport="False"      IniFile="\Software\Fast Reports" >
