How to add custom view to the layout?

Answer 1

Because your custom View is an inner class in your Activity the java compiler will output the name ActivityName$GraphicsView for that class. You can't use that name directly as the View name in the xml layout because of the $ character but you can do it like this:

where ActivityName is the name of the activity where your GraphicsView class is declared.
