kotlin - 无需 getter 直接从 Java 访问 kotlin 公共(public)字段

Question

下面是一个来自 Android 的模式示例(只是一个示例，对 android 细节不感兴趣):

/*Im a kotlin file*/
class ListItemViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    val text: = itemView.my_view
}

然后模式是您访问文本字段，如下所示:

/*Im a Java file*/
holder.text.setText("Metasyntactic variable");

不幸的是，有一个具有固定结构的大文件执行上述操作，然后:

/*Im a Java file, but this particular holder is a kotlin file*/
holder.getText().setText("Metasyntactic variable");

有可能解决这个问题吗？也许有一些 @Jvm注解

Answer 1

它是 @JvmField :

If you need to expose a Kotlin property as a field in Java, you need to annotate it with the @JvmField annotation. The field will have the same visibility as the underlying property. You can annotate a property with @JvmField if it has a backing field, is not private, does not have open, override or const modifiers, and is not a delegated property.
