MVP解绑

在presenter  class 类里面去定义一个制空

package com.example.zhangyifan1509a1207.presenter;

import com.example.zhangyifan1509a1207.modl.Bean;
import com.example.zhangyifan1509a1207.modl.Shoumodl;
import com.example.zhangyifan1509a1207.view.Iview;

/**
 * Created by Administrator on 2017/12/7.
 */

public class Shoupresenter implements Ipresenter{
    Iview iview;
    private final Shoumodl shoumodl;

    public Shoupresenter(Iview iview) {
        this.iview = iview;
        shoumodl = new Shoumodl();
    }

    //MVP解绑
    public void getmyneicun(){
        iview = null;
    }


    @Override
    public void getmymodl() {
        shoumodl.getimodl(this);
    }

    @Override
    public void getmypresenter(Bean bean) {
            iview.getiview(bean);
    }
}

然后在ManActivity调用解绑

package com.example.zhangyifan1509a1207;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.util.Log;

import com.example.zhangyifan1509a1207.modl.Bean;
import com.example.zhangyifan1509a1207.presenter.Shoupresenter;
import com.example.zhangyifan1509a1207.view.Iview;

import java.util.List;

public class MainActivity extends AppCompatActivity implements Iview{

    private Shoupresenter shoupresenter;
    private RecyclerView rv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        rv = findViewById(R.id.rv);
        shoupresenter = new Shoupresenter(this);
        shoupresenter.getmymodl();
    }

    //MVP
    @Override
    public void getiview(Bean bean) {
        List<Bean.NewslistBean> list = bean.getNewslist();
        Myadaper myadaper = new Myadaper(this,list);
        LinearLayoutManager manager = new LinearLayoutManager(this);
        rv.setLayoutManager(manager);
        rv.setAdapter(myadaper);
        Log.i("sssssssssssssss",bean.getNewslist().get(0).getTitle());
    }

    //调用MVP解绑
    @Override
    protected void onDestroy() {
        super.onDestroy();
        shoupresenter.getmyneicun();
    }
}
