请问各位大侠，问题出在何处？是employees.xml文件的存放路径有误，还是什么问题
到底怎样做才对啊？

Answer 4

你把文件放在src下面或者assert下都可以
把你的方法不要写成静态的就行啊
InputStream is=this.getClass().getClassLoader().getResourceAsStream("employees.xml");  
InputStream is=this.Context.getResources().getAssets().open("employees.xml");
          
            

Answer 5

getContext().getResources().getXml("")这种方法没有找到转成流的

Answer 6

使用InputStream is=this.Context.getResources().getAssets().open("employees.xml");
会显示Context cannot be resolved or is not a field

Answer 7

使用InputStream is=this.Context.getResources().getAssets().open("employees.xml");
运行后出现如下这样的异常

Answer 8

使用InputStream is=this.Context.getResources().getAssets().open("employees.xml");
然后将employees.xml文件放在src目录下就可以了
真的非常感谢！
