getting the screen density programmatically in android?

Question

How to get the screen density programmatically in android?

I mean: How to find the screen dpi of the current device?

Answer 1

Try this...

In kotlin

fun determineScreenDensityCode(): String {
      return when (resources.displayMetrics.densityDpi) {
         DisplayMetrics.DENSITY_LOW -> "ldpi"
         DisplayMetrics.DENSITY_MEDIUM -> "mdpi"
         DisplayMetrics.DENSITY_HIGH -> "hdpi"
         DisplayMetrics.DENSITY_XHIGH, DisplayMetrics.DENSITY_280 -> "xhdpi"
         DisplayMetrics.DENSITY_XXHIGH, DisplayMetrics.DENSITY_360, DisplayMetrics.DENSITY_400, DisplayMetrics.DENSITY_420 -> "xxhdpi"
         DisplayMetrics.DENSITY_XXXHIGH, DisplayMetrics.DENSITY_560 -> "xxxhdpi"
         else -> "Unknown code ${resources.displayMetrics.densityDpi}"
     }
}

You can call by println("density: ${determineScreenDensityCode()}") and the output will be System.out: density: xxxhdpi
