All the answers here show a dp->px conversion rather than px->dp, which is what the OP asked for.
Note that TypedValue.applyDimension
cannot be used to convert px->dp, for that you must use the method described here: https://stackoverflow.com/a/17880012/504611 (quoted below for convenience).
fun Context.dpToPx(dp: Int): Int {
return (dp * resources.displayMetrics.density).toInt()
}
fun Context.pxToDp(px: Int): Int {
return (px / resources.displayMetrics.density).toInt()
}
