Question

我看过Anko 0.8 - unresolved lparams reference，但是我没有在最外部的布局中使用lparams，就像在该链接中那样。

我在以下代码中得到“未解决的参考：lparams”（Android Studio中没有导入建议）。关于我错过和/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为1.2.71，$ anko_version为0.10.6）：

好的，所以...正如您在this diff中所见，从Anko 0.10.6开始，verticalLayout方法已被修改为采用LinearLayout.() -> Unit类型的初始化器lambda。前_LinearLayout.() -> Unit类型中的一种。下划线的_LinearLayout类是定义您正在寻找的lparams方法的类，这就是为什么由于此更改而使它丢失的原因。

此重大更改已经存在一个公开的问题：https://github.com/Kotlin/anko/issues/673

与此同时，您可以坚持使用0.10.5，也可以将linearLayout的使用方向明确：

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

    textView {
        text = "ASDF"
    }.lparams {

    }
}

未解决的参考：Anko 0.10.6中的verticalLayout的lparams
