MVP的工作原理

以上是MVP的工作原理图。其中大家注意的Presenter操作View和Mode都是通过接口来实现直接的调用。

MVP的工作流程

• Presenter负责逻辑的处理，
• Model提供数据，
• View负责显示。 
  作为一种新的模式，在MVP中View并不直接使用Model，它们之间的通信是通过Presenter来进行的，所有的交互都发生在Presenter内部，而在MVC中View会从直接Model中读取数据而不是通过 Controller。 
  　　

RxJava和Retrofit2.0使用

这二者的使用我就不罗嗦了，github中后好多demo，大家自己看。

MVP、RxJava和Reterofit2.0三者的整合现在开始讲解

首先说一下本项目的结构

• api包主要存放网络请求接口
• bean包中存放实体类
• model包中存放处理数据
• pesenter包中存放主导器
• view包中存放界面处理

view的代码：

/**
*WeatherView 用于处理界面显示
*/
public interface WeatherView {

    void showProgress();
    void hideProgress();
    void loadWeather(WeatherData weatherData);
}

package com.lidong.demo.android_rapid_development_of_library.mvp;

import android.support.v7.app.AppCompatActivity;

public class WeatherActivity extends AppCompatActivity implements WeatherView {

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_weather);
        ButterKnife.bind(this);
        setSupportActionBar(toolbar);
        mWeatherPresenter = new WeatherPresenterImp(this);
        mWeatherPresenter.getWeatherData("2", "苏州");
    }

    @Override

        LoadingUIHelper.showDialogForLoading(this,"获取数据",false);
    }

    @Override
    public void hideProgress() {
        LoadingUIHelper.hideDialogForLoading();
        Toast.makeText(this,"服务器异常",Toast.LENGTH_SHORT).show();
         mWeatherPresenter.onUnsubscribe();
    }

    @Override
    public void loadWeather(WeatherData weatherData) {
        Log.d("weatherData", "weatherData==" + weatherData.toString());
        textView1.setText("城市："+weatherData.getResult().getToday().getCity());
        textView2.setText("日期："+weatherData.getResult().getToday().getWeek());
        textView3.setText("今日温度："+weatherData.getResult().getToday().getTemperature());
        textView4.setText("天气标识：" +WeatherIDUtils.transfer(weatherData.getResult().getToday().getWeather_id().getFa()));
        textView5.setText("穿衣指数：" + weatherData.getResult().getToday().getDressing_advice());

        textView9.setText("旅游指数："+weatherData.getResult().getToday().getTravel_index());
    }
}

 @Override
 protected void onDestroy() {
     super.onDestroy();
     //取消注册
     mWeatherPresenter.onUnsubscribe();
 }

总结

最后总结一下，通过使用mvp对代码进行分层之后，模块化更加的清楚，假如要换网络框架，需要修改model层和api层的代码，其他的层的代码都不需要再动，这样各层之间保持单一职责。代码的易读性变得更强了。

MVP的工作原理

以上是MVP的工作原理图。其中大家注意的Presenter操作View和Mode都是通过接口来实现直接的调用。

MVP的工作流程

• Presenter负责逻辑的处理，
• Model提供数据，
• View负责显示。 
  作为一种新的模式，在MVP中View并不直接使用Model，它们之间的通信是通过Presenter来进行的，所有的交互都发生在Presenter内部，而在MVC中View会从直接Model中读取数据而不是通过 Controller。 
  　　

RxJava和Retrofit2.0使用

这二者的使用我就不罗嗦了，github中后好多demo，大家自己看。

MVP、RxJava和Reterofit2.0三者的整合现在开始讲解

首先说一下本项目的结构

• api包主要存放网络请求接口
• bean包中存放实体类
• model包中存放处理数据
• pesenter包中存放主导器
• view包中存放界面处理

view的代码：

/**
*WeatherView 用于处理界面显示
*/
public interface WeatherView {

    void showProgress();
    void hideProgress();
    void loadWeather(WeatherData weatherData);
}

        Toast.makeText(this,"服务器异常",Toast.LENGTH_SHORT).show();
         mWeatherPresenter.onUnsubscribe();
    }

    @Override
    public void loadWeather(WeatherData weatherData) {
        Log.d("weatherData", "weatherData==" + weatherData.toString());
        textView1.setText("城市："+weatherData.getResult().getToday().getCity());

总结

最后总结一下，通过使用mvp对代码进行分层之后，模块化更加的清楚，假如要换网络框架，需要修改model层和api层的代码，其他的层的代码都不需要再动，这样各层之间保持单一职责。代码的易读性变得更强了。
