android mvp模式下多个类继承单接口，数据同时回调打印

android MVP 单个activity 拆分成多个view, 当A view 点击按钮后，B /C view 继承的接口同时可以回调到A view的数据

MvpActivity 单个页面 代码

package com.example.demo.mvp.view;

import android.app.Activity;
import android.os.Bundle;

import com.example.demo.databinding.ActivityMvpBinding;
import com.example.demo.mvp.presenter.MvpPresenterClass;

public class MvpActivity extends Activity {
    // viewBinding数据绑定节约了findViewByid
    private ActivityMvpBinding binding;
    // 拆分的主view
    private MainView mainView;
    // P层
    private MvpPresenterClass presenterClass;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // 数据绑定
        binding = ActivityMvpBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());
        
        mainView = new MainView(binding, this);
        presenterClass = new MvpPresenterClass(this);
        mainView.updateMainView(presenterClass);
    }
}
