这一理念主要是一个**MvpView** (也就是Fragment or Activity)会关联一个MvpPresenter，并且管理**MbpPresenter**的声明周期。大家从上面的代码片段可以看到，Mosby使用Activity和Fragement生命周期来实现这一目的。通常presenter是绑定在该生命周期上的。所以初始化或者清理一些东西等操作（例如撤销异步运行任务）应该在 **presenter.onAttach()**和 presenter.onDetach()上进行。我们稍后会谈到presenter如何使用setRetainInstanceState(true) “避开”Fragment中的生命周期。我相信大家也注意到了， MvpPresenter是一个interface 。MVP模块提供一个 **MvpBasePresenter**，这个**MvpBasePresenter**只持有View（是一个Fragment或Activity）的弱引用，从而避免内存泄露。因此，当**presenter**想要调用view方法时，我们需要查看**isViewAttached()** 并使用**getView()**来获取引用，以检查view是否连接到了presenter。
##Loading-Content-Error (LCE)
通常Fragment会一直重复做某一件事。它在后台加载数据，同时显示加载view（即ProgressBar），并在屏幕上显示加载的数据，或者当加载失败时显示view错误。如今，下拉刷新支持很容易实现，因为SwipeRefreshLayout是Android支持库的组成部分。为了避免重复执行这一工作流，Mosby库的**MVP**模块提供了**MvpLceView**。
```
public interface MvpLceView
