How to make a transition between forms?

Question

Android

I made a button on the toolbar. How can I make it so that when you click on it, the settings form opens?

Answer 1

Create a new Activity, and the simplest transition code is this (Java again, Xamarin is reluctant):

Intent intent = new Intent(this, MyActivity2.class);
this.startActivity(intent);

Where exactly to write it - find it in the same place as about creating the options menu itself.
