这边已经保存了密码了，但是不能保存账号也用sharedpreferences来做保存么，具体代码是怎么实现的可以说一下么，我知道这个方法可以保存，但是没用过不知道怎么去操作，可以请教一下么

通过sharedpreferences工具类,键值对这是我的工具类,希望对你有所帮助

@monkey0928: 好的我去操作下，谢谢大神

@monkey0928: 它不需要去xml文件中配置账号的信息么，

@解闷的浩宇: 希望对你有所帮助,客气啦!!!

@解闷的浩宇: 是的   

@monkey0928: xml文件中需要配置账号的信息么，大神，可以加下你扣扣么，以后小弟有什么不懂的情况在您不忙的时候，给予一个请教
