用泛型类型扩展抽象类？

Question

How can I extent an abstract class like the following which has generic arguments?

@Singleton
public abstract class Presenter<V extends View, Proxy_ extends Proxy<?>> extends PresenterWidget<V> {

...
}

Answer 1

Class Presenter has simplified generic type Presenter<V, Proxy_> where

• V extends View
• Proxy_ extends Proxy<?>

Extending class should look like this:

public class MyPresenter extends Presenter<MyView, MyProxy> {
    ...
}

where

• MyView extends View
• MyProxy extends Proxy<?>

Answer 2

To extend MariuszS's answer: Generally the presenter defines the view interface:

public class MyPresenter extends Presenter<MyPresenter.MyView, MyProxy> {
    public static interface MyView extends View {
    ...
    }
...
