Answer 1

You probably extend Activity not AppCompatActivity. Also, your theme needs a proper parent.

<style name="AppTheme" parent="Theme.AppCompat">

Also make sure you have this call:

protected override void OnCreate(Bundle bundle)
{
    SetTheme(Resource.Style.AppTheme);
    base.OnCreate(bundle)

This solved my problem.
