Kotlin return value

Return and = Flexible application

Example 1

Fun sum (a:int,b:int): int{
    return a+b
}

Fun sum (a:int,b:int) = a + b

Example 2

Fun Max (A:int, b:int): Int {
    if (a > B)
        return a
    else
        return b
}

Fun Max (a:int, b:int) = if (a > B) a else B

Example 3

Fun Initui (): linearlayout {
        return verticallayout {
            button {
                text = "One"
            }
            TextView {
                Text = "}.lparams"
            {
                width = matchparent
                gravity = gravity.center_horizontal
            }
    }}

Fun Initui () = verticallayout {
        button {
            text = "One"
        }
        textView {
            text = "One"
        }.lparams {
            W Idth = matchparent
            gravity = Gravity.center_horizontal
        }
    }

The interface effect of example two implementation

Note:
1. When writing a layout file with Anko, write the Layoutparams property of the control after Lparams. If you specify Lparams (), but omit width or height, their default values are wrap_content.

2, Layoutparams it encapsulates layout (layout) position, height, width and other information, location information is whether the center, left and right margin and so on.
