我是Android开发的一名完全新手，并且在上课三周之后。该程序编译并运行得很好，直到我尝试更改任何EditText或滑动seekBar。Android：找不到资源例外
作业：创建抵押计算器应用程序，允许用户输入购买价格，首付金额和利率。根据这些值，应用程序应计算贷款金额并显示10年，20年和30年期贷款的每月付款。允许用户使用SeekBar选择一个自定义贷款期限（年），并显示该自定义贷款期限的每月付款。
我只把这些号码分成几年开始，并没有实现利益。目前只是输入和存储的内容。但这不是问题。此错误消息是我尝试更改第一个编辑文本时出现的内容。

我花了几个小时试图自己修复它并寻找解决方案。我不知道我是否看过错误的地方或什么，但是我处于绳索的尽头。
非常感谢您给予的帮助。如果需要更多信息，请提问。
编辑：添加了完整的错误信息。
呃哦，你刚才复制的XML文件没有任何修改？如果是这样，你将不得不删除＃20行上的//行9。 – Suzi 2015-02-10 06:03:01
请[编辑]问题：请包括整个错误信息。鉴于错误消息列出了行号，请确保您提供的代码与您从中获得错误消息的代码完全匹配。它目前不符合错误文本中的行号。 – Makyen 2015-02-10 06:04:20
我认为@ Vivek的回答将解决您的问题。 – 2015-02-10 06:20:22
