在调用Kotlin数据类中的超类构造函数之前访问函数

I'm using data classes in Kotlin to significantly reduce the amount of Java code I would otherwise have to write.

但是，在我的一个Java类中，我不确定如何在Kotlin中实现同样的结果.

My Java class looks a bit like this:

public class DataObject {

    private int mId;
    private String mName;

    public DataObject(int id, String name) {
        mId = id;
        mName = name;
    }

    public DataObject(Context context, int id) {
        mId = id;
        Cursor cursor = ...
        cursor.moveToFirst();
        mName = cursor.getString(...);
        cursor.close();
    }

    public int getId() {
        return mId;
    }

    public String getName() {
        return mName;
    }

}

I've tried to rewrite it in Kotlin, and so far I have this:

data class DataObject(val id: Int, val name: String) {

    constructor(context: Context, id: Int) : this(id, fetchName(context))

    private fun fetchName(context: Context): String {
        val cursor = ...
        cursor.moveToFirst()
        val name = cursor.getString(...)
        cursor.close()
        return name
    }

}

But my IDE (Android Studio) is underlining the part where I call fetchName(context) in my constructor in red. It displays the following message:

Cannot access fetchName before superclass constructor has been called

我应该如何解决这个问题？
