数据绑定编译器错误：＆＃34;无法解析SafeVarargs的类型＆＃34;

标签： android data-binding compiler-errors

我一直在努力让Android数据绑定工作2天，并且在问题发布之后一直是编译器问题，而现在这个问题我已经完全碰壁了。我用Google搜索，没有任何东西可以找到。

这是完整的日志：

java.lang.RuntimeException: failure, see logs for details.

我还尝试删除所有数据绑定xml和Activity代码，然后离开：

dataBinding{
        enabled = true
    }
在gradle应用程序文件中

，看看会发生什么，并且编译得很好。

伙计，实现数据绑定不应该这么难。

2 个答案:

答案 0 :(得分：8)

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">
  <data>
    <variable
      name="viewModel"
      type="com.my.asdf.MyViewModel"/> <-- deleted class
  </data>
  <LinearLayout .... />
</layout>
  1. 在布局资源中添加视图模型
  2. 删除视图模型类

    3. 那么你可以看到那个错误。所以你必须在布局资源文件中找到错误。

答案 1 :(得分：0)

当我在项目中更改应用程序ID并重命名文件夹时，我在某些“布局xml”文件中收到此错误，并且无法编译该项目。例如： com.xxx.myproject com.yyy.myproject 这是我解决问题的方法：在您的项目中，即使您找到并更改了应用程序ID，cookie仍保留在编译文件夹中。 我通过删除构建文件夹解决了此错误。重新编译项目时，这些文件夹已经被重建。无论如何都不要忘记备份您的项目：）

As shown in the picture
