用于快速引入 MVP 框架至 Android 应用开发中

添加依赖

1. 添加 jitpack 仓库至根目录下的build.gradle文件中

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

2. 添加编译依赖

dependencies {
    compile 'me.alzz:mvp:1.0.3'
}

快速使用

1. 定义 view 接口

public interface IMainView extends IView {
    void showMsg(String msg);
}

2. 定义 presenter 接口（可选）

public interface IMainPresenter extends IPresenter {
    /**
     * 从服务器读取消息
     */
    void queryMsg();
}

3. 继承 BasePresenter 实现 presenter

public class MainPresenter extends BasePresenter<IMainView> implements IMainPresenter {

    public void queryMsg() {
        // may be query from db or network
        String msg = "msg from query";
        // ... 

        mView.showMsg(msg);
    }
}

4. 继承BaseMvpActivity 并实现 view 接口。可考虑由基类继承 BaseMvpActivity

public class MainActivity extends BaseMvpActivity implements IMainView {

    private TextView mMsgTv;

    // 只需要声明，不需要赋值
    MainPresenter mMainPresenter;
    
    // 或者使用接口，实现类可放至单独的 module 中，编译时引用
    // IMainPresenter mMainPresenter;
    
    // 如果自己赋值也是可以的
    // MainPresenter mMainPresenter = new MainPresenter();
    // IMainPresenter mMainPresenter = new MainPresenter();


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mMsgTv = (TextView) findViewById(R.id.msg_tv);

        mMainPresenter.queryMsg();
    }

    @Override
    public void showMsg(String msg) {
        mMsgTv.setText(msg);
    }
}

Proguard

# 保留presenter默认构造函数
-keepclasseswithmembers class * extends me.alzz.mvp.BasePresenter {
    public <init>();
}
