android Mvp 模式将上下文作为视图传递

Question

我尝试将 Mainactivity 作为视图传递给演示者

(In MainActivity)    
mainPresenter = new MainPresenter(this);

(Presenter cont)
public MainPresenter(View view) {
      this.view = view;
      user  = new User();
   }

但是，这个抛出的错误是无效的转换之类的。我错过了什么吗？

你应该有这样的东西：

public interface YourView {
    void doSomething();
}

public MainActivity extends Activity implements YourView {

mainPresenter = new MainPresenter(this);

}

public MainPresenter(YourView view) {
      this.view = view;
      view.doSomething();
   }
