Given an array of Long values in Kotlin and a position parameter, when the position is in the middle-CodePudding

Spotify's lyrics API provides an Array of miliseconds to mark when the lyric line has changed. Having a Media Player that updates it's position every 50ms, how should i code in Kotlin the way to find the correct lyric line? The position param can be in the middle of two values of the array, so I want to get the lowest one of that two.

I tried to get the lowest value compared to the position parameter but lol, it will always be the first value of the Array... Silly fault of mine.

CodePudding user response：

If I correctly understand, you need simply use min function for compare two numbers in Kotlin and find the low one: link

Insert the position param into the array, sort it, find its index and use it to get the closest value.


    val array: MutableList<Long> = mutableListOf(4L, 9L, 5L, 1L)
    val position = 7L
    
    array.add(position)
    println(array[array.sorted().indexOf(position) - 1])

Output: 5
