android - Unresolved reference : lparams for verticalLayout in Anko 0. 10.6

Question

我看过Anko 0.8 - unresolved lparams reference ，但我没有像该链接那样在最外层布局中使用 lparams。

我在以下代码中得到“ Unresolved 引用:lparams”(Android Studio 中没有导入建议)。关于我遗漏和/或忽略的内容有什么想法吗？

class LoginActivityUi: AnkoComponent<LoginActivity> {

    override fun createView(ui: AnkoContext<LoginActivity>): View = with(ui) {
        verticalLayout {
            backgroundColorResource = R.color.background_page

            textView{
                text = "ASDF"
            }.lparams{

            }
        }
    }

}

这是我的依赖项($kotlin_version 是 1.2.71，$anko_version 是 0.10.6):

好的，所以... 正如您在 this diff 中看到的那样，从 Anko 0.10.6 开始，verticalLayout 方法被修改为采用 LinearLayout.() -> Unit 类型的初始化 lambda 而不是之前的 _LinearLayout .() -> 单位 类型。带下划线的 _LinearLayout 类是定义您要查找的 lparams 方法的类，这就是它因此次更改而丢失的原因。

这里已经有一个针对此重大更改的未解决问题:https://github.com/Kotlin/anko/issues/673

与此同时，您可以坚持使用 0.10.5，也可以使用具有明确方向的 linearLayout 作为解决方法:

linearLayout {
    orientation = LinearLayout.VERTICAL
    backgroundColorResource = R.color.background_page

    textView {
        text = "ASDF"
    }.lparams {

    }
}
