Java code: // Converts 14 dip into its equivalent px float dip = 14f; Resources r = getResources(); float px = TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, dip, r.getDisplayMetrics() ); Kotlin code: val dip = 14f val r: Resources = resources val px = TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, dip, r.displayMetrics ) Kotlin extension: val Number.toPx get() = TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, this.toFloat(), Resources.getSystem().displayMetrics)
If you want the display dimensions in pixels you can use getSize: Display display = getWindowManager().getDefaultDisplay(); Point size = new Point(); display.getSize(size); int width = size.x; int height = size.y; If you’re not in an Activity you can get the default Display via WINDOW_SERVICE: WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); If you … Read more
