同时构建项目。我收到以下错误：引用必须以“@”开头：

错误：构建失败

我将 gradle 生成器错误放在要点中 here

请任何人帮助我

Answer 1

尝试检查您的 xml 文件是否有空 ID

Answer 2

您正在调用一个没有正确引用的组件，例如：

<ImageView
    android:id="ImgView"
    android:layout_width="match_parent"
 ..../>

正确的方法

<ImageView
    android:id="@+id/ImgView"
    android:layout_width="match_parent"
 ..... />

您必须验证 xml 引用的哪一部分不正确
