### 依赖包
```

##### Activity
```

##### View
```

 MainActivity 的 MvpViewable
 */

##### Presenter

public MainPresenter( @NonNull MainView view ) {
        super( view );
        //mModel1 和 mModel1_1 为共享Model，当 mModel1 内部发生改变时， mModel1_1 也会跟着改变

//mModel2_2 重新实例的Model，可以理解为 new了一个 Model2，与 mModel2 互不干预

//在实际开发中，mModel1 和 mModel1_1 可以在不同的类中实现共享。
        //例如：MainPresenter、OtherPresenter 两个 Presenter 都持有 Model1
        
        /* 回调结果。Handler.post提交 */
        viewCall(v -> {
            //回调处理结果

##### Model
```
