public interface INetModel {
    void askForNet(NetSourceCallBack callBack);
}

接口的实现类

public class NetModel implements INetModel {
    private String steamData = "";

    Handler handler = new Handler();

    @Override
    public void askForNet(final NetSourceCallBack callBack) {
        netUtils = new HttpUrlUtils();
        threadPool = ThreadPoolManager.getInstance();
        SteamTask steamTask = new SteamTask();
        NewsTask newsTask = new NewsTask();
        threadPool.putExecutableTasks(steamTask);
        threadPool.putExecutableTasks(newsTask);
        handler.postDelayed(new Runnable() {
            @Override

                }
            }
        }, 2000);

    }

    class SteamTask implements Runnable {

NetSourceCallBack

package com.example.admin.mvpsample1.Model;

public interface NetSourceCallBack {
    void onSuccess(String steam,String newsData);

    void onFailure(String errorCode);
}

INetPresent

package com.example.admin.mvpsample1.Presenter;

public interface INetPresent {
    void askForNet();
}

实现类

public class NetPresenter implements INetPresent {
    private ShowNetData showNetview;
    private NetModel netModel;
    public NetPresenter(ShowNetData showNetview,NetModel netModel){
        this.showNetview=showNetview;
        this.netModel=netModel;
    }

    @Override
    public void askForNet() {
        showNetview.showLoading("加载中");
        netModel.askForNet(new NetSourceCallBack() {
            @Override
            public void onSuccess(String steam, String newsData) {
                showNetview.hideLoading();
                showNetview.showResult("加载成功");
                showNetview.setData(steam,newsData);
            }

            @Override
            public void onFailure(String errorCode) {
                showNetview.hideLoading();
                showNetview.showResult("加载失败");

            }
        });
    }
}

ShowNetData

package com.example.admin.mvpsample1.View;

public interface ShowNetData {
    void showLoading(String msg);

    void hideLoading();

    void showResult(String result);

    void setData(String steam,String news);
}

Activity

public class NetActivity extends AppCompatActivity implements ShowNetData{
    private TextView textSteam;
    private TextView textJvHe;
    private NetPresenter presenter;
    private ProgressDialog progressDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_net);
        inintView();
        presenter.askForNet();
    }

    private void inintView(){
        textSteam=findViewById(R.id.tt1);
        textJvHe=findViewById(R.id.tt2);
        progressDialog = new ProgressDialog(this);
        presenter = new NetPresenter(this, new NetModel());
    }
    @Override
    public void showLoading(String msg) {
        progressDialog.setMessage(msg);
        if (!progressDialog.isShowing()){
            progressDialog.show();
        }
    }

    @Override
    public void hideLoading() {
        if(progressDialog.isShowing()){
            progressDialog.dismiss();
        }
    }

    @Override
    public void showResult(String result) {
        Toast.makeText(NetActivity.this,result,Toast.LENGTH_SHORT).show();
    }

    @Override
    public void setData(String steam, String news) {
        textJvHe.setText(news);
        textSteam.setText(steam);
