How do I calculate the dimensions of an Android device in kotlin?
I have tried:
val displayMetrics = DisplayMetrics()
windowManager.defaultDisplay.getMetrics(displayMetrics)
var width = displayMetrics.widthPixels
var height = displayMetrics.heightPixels
It gives me the following error:
"getter for defaultDisplay: Display!' is deprecated. Deprecated in Java:"
Thank you
If you look into the docs for WindowManager.getDefaultDisplay() you'll find that there's a suggestion on what to use instead:
Deprecated: Use
Context#getDisplay()instead.
The new way to do it now is with context, This method is the one I used to obtain the real height, depending on the orientation of the screen
Note * Make sure for the context of an activity or fragment
fun getDisplayHeight(context: Context): Int {
val windowManager = context.getSystemService(Context.WINDOW_SERVICE) as WindowManager
val displayMetrics = DisplayMetrics()
try {
context.display?.getRealMetrics(displayMetrics)
} catch (e: NoSuchMethodError) {
windowManager.defaultDisplay.getRealMetrics(displayMetrics)
}
return if (context.resources.configuration.orientation == Configuration.ORIENTATION_LANDSCAPE) {
minOf(displayMetrics.widthPixels, displayMetrics.heightPixels)
} else {
maxOf(displayMetrics.widthPixels, displayMetrics.heightPixels)
}
}
You can refer to the following documentation for more details.
