Hardcoding the size or using reflection to get the value of status_bar_height is considered bad practice. Chris Banes talked about this in at the Droidcon New York. The recommended way of getting the status bar size is via the OnApplyWindowInsetsListener:
myView.setOnApplyWindowInsetsListener { view, insets -> {
val statusBarSize = insets.systemWindowInsetTop
return insets
}
This was added in API 20 and is also backported via ViewAppCompat.
