[Android][Kotlin] 화면 사이즈 구하기(Size)

 

fun getScreenSize(context: Context): Size {
    val wm = context.getSystemService(Context.WINDOW_SERVICE) as WindowManager
    return if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        val windowMetrics = wm.currentWindowMetrics
        val insets = windowMetrics.windowInsets
            .getInsetsIgnoringVisibility(WindowInsets.Type.systemBars())
        val width = windowMetrics.bounds.width() - insets.left - insets.right
        val height = windowMetrics.bounds.height() - insets.bottom - insets.top
        Size(width, height)
    } else {
        val displayMetrics = DisplayMetrics()
        wm.defaultDisplay.getMetrics(displayMetrics)
        val width = displayMetrics.widthPixels
        val height = displayMetrics.heightPixels
        Size(width, height)
