Horizontal LinearLayout in Anko

Question

What is a good way to do a horizontalLayout in anko / kotlin ? verticalLayout works fine - could set orientation on it but it feels wrong. Not sure what I am missing there.

Answer 1

Just use a linearLayout() function instead.

linearLayout {
    button("Some button")
    button("Another button")
}

Answer 2

Yeah, LinearLayout is by default horizontal, but I tend to be extra specific and rather use a separate horizontalLayout function for that.

You can simply add the horizontalLayout function to your project:

  val HORIZONTAL_LAYOUT_FACTORY = { ctx: Context ->
    val view = _LinearLayout(ctx)
    view.orientation = LinearLayout.HORIZONTAL
    view
  }

  inline fun ViewManager.horizontalLayout(@StyleRes theme: Int = 0, init: _LinearLayout.() -> Unit): _LinearLayout {
      return ankoView(HORIZONTAL_LAYOUT_FACTORY, theme, init)
  }

I have opened a feature request at Anko: https://github.com/Kotlin/anko/issues/413
