MVP原生登陆注册

程序员文章站 2022-04-18 17:25:40

...

首先需要两个接口

	//登录
    public final static String LOGIN_API="http://172.17.8.100/small/user/v1/login";
    //注册
    public final static String REG_API="http://172.17.8.100/small/user/v1/register";

创建一个登陆的bean包

public class LoginBean {
    public String message;
    public String status;

    public String getStatus() {
        return status;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public void setStatus(String status) {
        this.status = status;
    }
}

创建接口RequestCallBack

public interface RequestCallBack {
    void Failure(String string);
    void Success(LoginBean loginBean);
}

创建契约类

public interface LoadContract {
    //p层
    public abstract class LloadPresenter{
        public abstract void Login(HashMap<String,String>map);
        public abstract void reg(HashMap<String,String>map);
    }
    //m层
    interface LloadModel{
        void Login(HashMap<String,String> map, String string, RequestCallBack callBack);
    }
    //v层
    interface LloadView{
        void Failure(String string);
        void Success(LoginBean loginBean);
        void error(String error);
    }
}

创建model层

import android.os.Handler;

import com.google.gson.Gson;

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import jiaoyibo.bawei.com.dengluzhucelianxi.bean.LoginBean;
import jiaoyibo.bawei.com.dengluzhucelianxi.contract.LoadContract;
import jiaoyibo.bawei.com.dengluzhucelianxi.net.RequestCallBack;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.FormBody;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class LoadModel implements LoadContract.LloadModel {
    private Handler handler = new Handler();
    @Override
    public void Login(HashMap<String, String> map, final String string, final RequestCallBack callBack) {
        //创建OkHttpClient方法
        OkHttpClient okHttpClient = new OkHttpClient.Builder().build();
        //请求体
        FormBody.Builder builder = new FormBody.Builder();
        //for循环添加参数
        for(Map.Entry<String,String>p:map.entrySet()){
            builder.add(p.getKey(),p.getValue());
        }
        //创建Request
        Request request = new Request.Builder()
                .url(string)
                .post(builder.build())
                .build();

        okHttpClient.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                handler.post(new Runnable() {
                    @Override
                    public void run() {
                        callBack.Failure("网络连接超时");
                    }
                });
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                String result = response.body().string();
                //判断响应码
                if(response.code()==200){
                    //解析数据的方法
                    getjson(result,callBack);
                }
            }

            private void getjson(String result, final RequestCallBack callBack) {
                final LoginBean loginBean = new Gson().fromJson(result, LoginBean.class);
                if(loginBean!=null){
                    handler.post(new Runnable() {
                        @Override
                        public void run() {
                            callBack.Success(loginBean);
                        }
                    });
                }
            }
        });
    }
}

创建presenter层

import java.util.HashMap;

import jiaoyibo.bawei.com.dengluzhucelianxi.api.UserApi;
import jiaoyibo.bawei.com.dengluzhucelianxi.bean.LoginBean;
import jiaoyibo.bawei.com.dengluzhucelianxi.contract.LoadContract;

import jiaoyibo.bawei.com.dengluzhucelianxi.net.RequestCallBack;
import jiaoyibo.bawei.com.dengluzhucelianxi.vadio.VadoiUtil;

/**

 */
public class LoadPresenter extends LoadContract.LloadPresenter {
    private LoadContract.LloadView lloadView;
    private final LoadModel loadModel;

    public LoadPresenter(LoadContract.LloadView lloadView) {
        this.lloadView = lloadView;
        loadModel = new LoadModel();
    }

    @Override
    public void Login(HashMap<String, String> map) {
        String phone = map.get("phone");
        if(!VadoiUtil.isMobile(phone)){
            lloadView.error("手机号登陆不对");
            return;
        }
        loadModel.Login(map, UserApi.LOGIN_API, new RequestCallBack() {
            @Override
            public void Failure(String string) {
                if(lloadView!=null){
                    lloadView.Failure(string);
                }
            }

            @Override
            public void Success(LoginBean loginBean) {
                if(lloadView!=null){
                    lloadView.Success(loginBean);
                }
            }
        });
    }

    @Override
    public void reg(HashMap<String, String> map) {
        String phone = map.get("phone");
        if(!VadoiUtil.isMobile(phone)){
            lloadView.error("手机号登陆不对");
            return;
        }
        loadModel.Login(map, UserApi.REG_API, new RequestCallBack() {
            @Override
            public void Failure(String string) {
                if(lloadView!=null){
                    lloadView.Failure(string);
                }
            }

            @Override
            public void Success(LoginBean loginBean) {
                if(lloadView!=null){

                }
            }
        });
    }
