[mono-android] How to use "dip" or "dp" layout dimension for LayoutParams width and height?

[Tomasz Cielecki]

Just like when programming Java for Android, LayoutParams does not
have a way to set dp or sp, the only thing it knows is px, so you have
to calculate it yourself. However this is quite simple.

In an activity:

    var scale = Resources.DisplayMetrics.Density;
    var pixels = (int) (dps * scale + 0.5f);

Where dps is the dp value you want.

In a View you can get the scale from the Context like:

    var scale = Context.Resources.DisplayMetrics.Density;
