我有一个登录活动，该活动使应用程序崩溃，活动布局 ID 的 int 无效。有没有其他人看到这个错误，因为我要疯了。我在应用程序中有几个扩展 RoboSherlockActivity 的类，但只有这个导致崩溃。该活动是一个简单的登录页面，其中包含两个用于电子邮件和密码的 EditText 以及一个提交按钮，以及另一个导致 Facebook 登录的按钮。

这条线是什么？

android:scrollbars="?orientation_specific_scrollbars"

除非这是我不熟悉的资源值的某种符号，否则这是您的问题。该scrollbars属性的唯一有效值是：

  • none“不显示滚动条。”
  • horizontal“仅显示水平滚动条。”
  • vertical“仅显示垂直滚动条。”

您需要将其更改为这些值之一。

崩溃发生在

java.lang.NumberFormatException: Invalid int: "?2130772074"

在您的 xml 中某处放置了？2130772074，将其更改为一个数字。
