单击注册会导致Android应用程序崩溃

博观而约取，厚积而薄发。这篇文章主要讲述单击注册会导致Android应用程序崩溃相关的知识，希望能为你提供帮助。
当电子邮件和密码字段为空时，单击注册会使应用程序崩溃，但是当名称字段为空时，它可以正常运行似乎是什么问题？

这是应该发生的事情:(完全在名称文本中工作，但在其他edittexts中没有）

任何帮助将不胜感激：D
答案我的猜测是它与你放入@style/TextLabel的东西有关。
当您遇到密码或电子邮件错误时，您会以编程方式请求关注。这很好，但是当发生这种情况时，你的风格中正在寻找一种不存在的颜色资源。这就是导致错误的原因。
另一答案【单击注册会导致Android应用程序崩溃】错误似乎是textview的getColor（）方法，你的主要颜色有一些问题，请检查。
