The following code snippet shows how to converts DP unit to equivalent pixels, depending on device density. It returns a float value to represent px equivalent to dp depending on device density.
public static float convertDpToPixel(float dp, Context context){
Resources resources = context.getResources();
DisplayMetrics metrics = resources.getDisplayMetrics();
float px = dp * (metrics.densityDpi / 160f);
return px;
}
Where does the magic number 160 come from? [Edit] Nevermind, I should read more before I open my mouth. DP = 1.0 on a 160 dpi screen.
