在Anko DSL中创建自定义View/ViewGroup类

问题描述：

我想创建一个自定义视图，它只是一些Android视图的包装.我考虑创建一个自定义ViewGroup，以管理其子视图的布局，但是我不需要这种复杂性.我基本上想做的是这样的:

I want to create a custom View which is just a wrapper of some Android Views. I looked into creating a custom ViewGroup which manages the layout of it's child views, but I don't need such complexity. What I basically want to do is something like:

class MainActivity
verticalLayout {
  textView {
    text = "Something that comes above the swipe"
  }
  swipeLayout {
  }
}

class SwipeLayout
linearLayout {
  textView {
    text = "Some text"
  }
  textView {
    text = "Another text"
  }
}

原因是我想将SwipeLayout代码移到一个单独的文件中，但不想自己做任何复杂的布局工作.使用Anko可以做到吗?

The reason is that I'd like to move the SwipeLayout code into a separate file but don't want to do any complex layout stuff myself. Is this possible using Anko?

根据建议，如果视图是根布局，是否可以在Kotlin Anko中重用布局解决了此问题.但是，如示例所示，我想将其包含在另一个布局中.有可能吗?

As suggested, Is it possible to reuse a layout in Kotlin Anko solves this problem if the view is a root layout. But as shown in the example, I'd like to include this within another layout. Is that possible?

答

您可以使用ViewManager.

you can use ViewManager.

fun ViewManager.swipeLayout() = linearLayout {
  textView {
    text = "Some text"
  }
  textView {
    text = "Another text"
  }
}

class MainActivity
  verticalLayout {
    textView {
      text = "Something that comes above the swipe"
    }
    swipeLayout {}
}
