If you need set a fixed text size for your application, you try using the following code to implement this feature:

private void initFontScale()
{
     Configuration configuration = Resources.Configuration;
     configuration.FontScale = (float)1.45;
     //0.85 small, 1 standard, 1.15 big，1.3 more bigger ，1.45 supper big 
     DisplayMetrics metrics = new DisplayMetrics();
     WindowManager.DefaultDisplay.GetMetrics(metrics);
     metrics.ScaledDensity = configuration.FontScale * metrics.Density;
     BaseContext.Resources.UpdateConfiguration(configuration, metrics);
}

protected override void OnCreate(Bundle bundle)
{
    initFontScale();
    ...
}
