    [Activity(Label = "MonoFloatView", MainLauncher = true, Icon = "@drawable/icon")]
    public class MyFloatViewActivity : Activity
    {

        private IWindowManager wm = null;
        private WindowManagerLayoutParams wmParams = null;

        private MyFloatView myFV = null;

        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            SetContentView(Resource.Layout.Main);

        }

        private void createView()
        {
            //myFV = new MyFloatView(getApplicationContext());   //java
            myFV = new MyFloatView(ApplicationContext);
            myFV.SetImageResource(Resource.Drawable.Icon);
            //wm = (WindowManager)getApplicationContext().getSystemService("window");

            //i don't know the getApplication, how to write in monodroid?
            wmParams = ((MyApplication)getApplication()).getMywmParams();

            wmParams.Type = LayoutParams.TYPE_PHONE;   
            wmParams.Format = PixelFormat.RGBA_8888; 

            wmParams.Flags = LayoutParams.FLAG_NOT_TOUCH_MODAL
                              | LayoutParams.FLAG_NOT_FOCUSABLE;

            wmParams.Gravity = Gravity.LEFT | Gravity.TOP;  
            wmParams.X = 0;
            wmParams.Y = 0;

            wmParams.Width = 40;
            wmParams.Height = 40;

            wm.AddView(myFV, wmParams);

        }

        public override void onDestroy()
        {
            base.OnDestroy();
            wm.RemoveView(myFV);
        }
    }

If you're in an Activity, you should be able to use:

this.Application
