使用Kotlin进行数据绑定会导致Resources $ NotFoundException
上下文
我正在使用一个利用数据绑定的库来通过BindingAdapter在任何View上定义一个自定义属性：
@BindingAdapter({"attribute"}) public static void bindAttribute(@NonNull View view, String attribute) {...}
这使我可以定义由库在运行时处理的自定义属性：
<?xml version="1.0" encoding="utf-8"?> <layout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:algolia="http://schemas.android.com/apk/res-auto"> <LinearLayout <!-- ... --> android:orientation="horizontal"> <ImageView <!-- ... --> algolia:attribute='@{"objectID"}'/> </LinearLayout> </layout>
这个视图然后被用作子类RecyclerView的ViewHolder的itemLayout 。
所有这些在我的Java应用程序中工作正常。
问题
我开始在Kotlin建立一个类似的应用程序。 要使用数据绑定，我按照文档的指南，并添加以下内容：
// ./app/build.gradle apply plugin: 'kotlin-kapt' android { dataBinding { enabled true } ... } dependencies { kapt "com.android.databinding:compiler:$plugin_version" ... }
// ./build.gradle ext.plugin_version = '2.3.3' dependencies { classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" ... }
但是，运行应用程序并显示RecyclerView会在其onCreateViewHolder触发一个Exception：

我不明白Kotlin项目中的相同代码如何触发Resources$NotFoundException 。 此外，资源ID似乎很奇怪： 0xffffffd6等于4294967254 ，这太大，不能成为一个有效的整数。
什么可能导致这样的问题？ 我是否错过了在Kotlin应用程序中使用数据绑定的BindingAdapter ？
该问题是由底层库发送无效的View资源ID引起的。
