无法获取TextInputEditText的工作OutlinedBox。Stackoverflow上存在similar question，但所有解决方案都不起作用。
只要我添加android:style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"到代码中，表单就会从预览中消失，当我尝试构建apk时，会出现以下错误：

Android resource linking failed
com.my.app-main-50:/layout/fragment_login.xml:32: error: attribute android:style not found.
error: failed linking file resources.

只需将style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
也不起作用
