Kotlin 如何在 Fragment 中使用 Anko DSL

发布于11月17日

Github wiki page显示了Activity实例中要使用的示例:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    verticalLayout {
        padding = dip(30)
        editText {
            hint = "Name"
            textSize = 24f
        }
        editText {
            hint = "Password"
            textSize = 24f
        }
        button("Login") {
            textSize = 26f
        }
    }
}

如何在Fragment内做到同样的事情呢？

我试着把verticalLayout块放在onCreateView块，但这个方法无法解决.我增加了anko-support-v4个依赖项，但仍然没有运气.

推荐答案

After digging up anko-support-v4 source code plus some trial and errors, I have found a workaround although I'm not sure if it's the right/recommended way. It seems a little undocumented.

A sample from my Fragment code:

override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View? {

    return UI {
        verticalLayout {
            linearLayout {
                avatar = imageView().lparams(width = dip(48), height = dip (48))
                name = textView().lparams(width = 0, weight = 1f)
            }

            linearLayout {
                // ...
            }
        }
    }.toView()
}
