我有两种屏幕布局。 Activity 在为移动设备设置布局时工作正常,但在为平板设备设置布局时导致错误。主要问题是:

Caused by: java.lang.RuntimeException: view must have a tag at com.mypackage.DataBinderMapperImpl.getDataBinder(DataBinderMapperImpl.java:941)

不过,当我在移动设备上安装应用程序时,我没有遇到这个问题。

我通过这种方式设置 Activity 布局:

val resetPasswordActivityBinding = DataBindingUtil.setContentView<ResetPasswordActivityBinding>(this,
R.layout.reset_password_activity)
resetPasswordActivityBinding.resetPasswordViewModel = resetPasswordViewModel

这是我的平板电脑屏幕 XML 布局:

最佳答案

当我遇到这个问题时:

  • 定义布局资源的库模块
  • 依赖于定义相同布局资源的库模块的应用程序模块
  • 库布局资源是为数据绑定(bind)设置的(例如,根 <layout> 元素),但该布局资源的应用模块版本不是

在我的例子中,应用程序模块的布局是我创建项目时遗留下来的。删除它可以解决问题。
