Android Bootcamp [WK2 – D1]

I’ve been going thru the Your First Kotlin Android App: Polishing the App

You can add parameters to the @Preview for changing the size of the preview device.

    fun pointsForCurrentRound(): Int {
        return when (val diff = abs( targetValue -  sliderToInt )) {
            0 -> { 200 }
            1 -> { 149 }
            2 -> { 123 }
            else -> { min(100, 100 - diff) }
        }
    }

    fun alertTitle(): Int {
        val difference = abs(targetValue - sliderToInt)

        val title: Int = when {
            difference == 0 -> {
                R.string.alert_title_1
            }
            difference < 5 -> {
                R.string.alert_title_2
            }
            difference <= 10 -> {
                R.string.alert_title_3
            }
            else -> {
                R.string.alert_title_4
            }
        }


        return title

    }

The switch statement from most things, can be handled using a when.

The structure window helps you jumping between sections of code.
