how to get screen width and screen height in a composable function?

The simplest way is to use

ContextAmbient

for getting a

Context

and after it we can use

DisplayMetrics

. Code:

val displayMetrics = DisplayMetrics()
(ContextAmbient.current as Activity)
    .windowManager
    .defaultDisplay
    .getMetrics(displayMetrics)

val widthPx = displayMetrics.widthPixels
val heightPx = displayMetrics.heightPixels

Thanks @alexzhukovich

Is that really what you want, or are you just trying to figure out how much space your composable has to take up?

@Socheat KHAUV a handy helper here:

@Composable
fun Dp.toPx(): Px = with(DensityAmbient.current) {
    return@toPx this@toPx.toPx()
}

for an easier time using in progress apis that may require px 🙂 just make sure you actually do need to use px though

@Leland Richardson [G] - actually i wanted to display video and resize its width to be the same as screen width and maintaining its aspect ratio. below is my code. I am not sure is there another way to do it.
