Convert dip to px in Android

Question

I had written method to get the pixels from dip but it is not working. It give me runtime error.

Actually I was running this method in separate class and initialized

Answer 1

Try this:

Java

public static float dipToPixels(Context context, float dipValue) {
    DisplayMetrics metrics = context.getResources().getDisplayMetrics();
    return TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dipValue, metrics);
}

Kotlin

fun Context.dipToPixels(dipValue: Float) =
    TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dipValue, resources.displayMetrics)
