处理的方法就是

在当前类的第一行(package位置)会提示:Multiple markers at this line

- The type org.xmlpull.v1.XmlPullParser cannot be resolved. It is indirectly referenced from required .class files

- The type org.xmlpull.v1.XmlPullParser cannot be resolved. It is indirectly referenced from required .class files

- The type org.xmlpull.v1.XmlPullParserException cannot be resolved. It is indirectly referenced from 

required .class files

这种信息,这是由于XStream仅仅是一个jar文件,可是它里面会依赖一个jar包,依赖的jar包是:xmlpull_1_0_5.jar、仅仅要把这个jar包引入之后。问题就可以解决!
