封装Okhttp+retrofit+rxjava使用MVP模式实现登录注册

一，首先就是两个页面布局

    1，登录页面的布局

 

xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

            android:id="@+id/phone"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp"
        android:gravity="center"
        android:hint="请输入手机号" />

            android:id="@+id/password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp"
        android:gravity="center"
        android:hint="请输入密码" />

            android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp"
        android:gravity="center"
        android:orientation="horizontal">

                    android:id="@+id/login"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="登录" />

                    android:id="@+id/reg"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="注册" />
    

    2，注册页面的布局

xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

            android:id="@+id/phone"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp"
        android:gravity="center"
        android:hint="请输入手机号" />

            android:id="@+id/password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp"
        android:gravity="center"
        android:hint="请输入密码" />

            android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp"
        android:gravity="center"
        android:orientation="horizontal">

                    android:id="@+id/reg"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="注册" />
    

二，拿到登录和注册的接口，分别请求，创建出实体bean类。

           1，登录bean类

public class LoginBean {

    /**
     * msg : 登录成功
     * code : 0
     * data : {"age":null,"appkey":"9cdef4b09eb65685","appsecret":"66B6E2E5F439618D01B67FBAEA31EFDA","createtime":"2018-01-15T16:19:03","email":null,"fans":null,"follow":null,"gender":null,"icon":null,"latitude":null,"longitude":null,"mobile":"18765432100","money":null,"nickname":null,"password":"473344696F4685CAE5B5B3C354BC77BE","praiseNum":null,"token":"AFD92DF6C6046F01B76D7C551AEC985B","uid":4362,"userId":null,"username":"18765432100"}
     */

    private String msg;
    private String code;
    private DataBean data;

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public DataBean getData() {
        return data;
    }

    public void setData(DataBean data) {
        this.data = data;
    }

    public static class DataBean {
        /**
         * age : null
         * appkey : 9cdef4b09eb65685
         * appsecret : 66B6E2E5F439618D01B67FBAEA31EFDA
         * createtime : 2018-01-15T16:19:03
         * email : null
         * fans : null
         * follow : null
         * gender : null
         * icon : null
         * latitude : null
         * longitude : null
         * mobile : 18765432100
         * money : null
         * nickname : null
         * password : 473344696F4685CAE5B5B3C354BC77BE
         * praiseNum : null
         * token : AFD92DF6C6046F01B76D7C551AEC985B
         * uid : 4362
         * userId : null
         * username : 18765432100
         */

        private Object age;
        private String appkey;
        private String appsecret;
        private String createtime;
        private Object email;
        private Object fans;
        private Object follow;
        private Object gender;
        private Object icon;
        private Object latitude;
        private Object longitude;
        private String mobile;

        private String token;
        private int uid;
        private Object userId;
        private String username;

        public Object getAge() {
            return age;
        }

        public void setAge(Object age) {
            this.age = age;
        }

        public String getAppkey() {
            return appkey;
        }

        public void setAppkey(String appkey) {
            this.appkey = appkey;

            this.createtime = createtime;
        }

        public Object getEmail() {
            return email;
        }

        public void setEmail(Object email) {
            this.email = email;
        }

        public Object getFans() {
            return fans;
        }

        public void setFans(Object fans) {
            this.fans = fans;
        }

        public Object getFollow() {
            return follow;
        }

        public void setFollow(Object follow) {
            this.follow = follow;
        }

        public Object getGender() {
            return gender;
        }

        public void setGender(Object gender) {
            this.gender = gender;
        }

        public Object getIcon() {
            return icon;
        }

        public void setIcon(Object icon) {
            this.icon = icon;
        }

        public Object getLatitude() {
            return latitude;
        }

        public void setLatitude(Object latitude) {
            this.latitude = latitude;
        }

        public Object getLongitude() {
            return longitude;
        }

        public void setLongitude(Object longitude) {
            this.longitude = longitude;
        }

        public String getMobile() {
            return mobile;
        }

        public void setMobile(String mobile) {
            this.mobile = mobile;
        }

        public Object getMoney() {
            return money;
        }

        public void setMoney(Object money) {
            this.money = money;
        }

        public Object getNickname() {
            return nickname;
        }

        public void setNickname(Object nickname) {
            this.nickname = nickname;
        }

        public String getPassword() {
            return password;
        }

        public void setPassword(String password) {
            this.password = password;
        }

        public Object getPraiseNum() {
            return praiseNum;
        }

        public void setPraiseNum(Object praiseNum) {
            this.praiseNum = praiseNum;
        }

        public String getToken() {
            return token;
        }

        public void setToken(String token) {

        }

        public int getUid() {

        }

        public String getUsername() {
            return username;
        }

        public void setUsername(String username) {
            this.username = username;
        }
    }
}

2，注册类的Bean类

public class RegBean {

    /**
     * msg : 天呢！用户名或密码不能为空
     * code : 1
     * data : {}
     */

    private String msg;
    private String code;
    private String data;

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getData() {
        return data;
    }

    public void setData(String data) {
        this.data = data;
    }
}

三，okhttp+retrofit+rxjava封装

         1，ApiServi接口

   

public interface ApiService {



    @GET
    Observable get(@Url String url, @QueryMap Map, String> map);


    @FormUrlEncoded
    @POST
    Observable post(@Url String url, @FieldMap Map, String> map);



}

           2，BaseObserver

public abstract class BaseObserver<T> implements Observer {


    @Override
    public void onSubscribe(Disposable d) {

    }

    @Override
    public void onNext(String s) {



        try {
            Type genType = getClass().getGenericSuperclass();
            Type[] params = ((ParameterizedType) genType).getActualTypeArguments();
            Class entityClass = (Class) params[0];
            Gson gson = new Gson();
            T t = (T)gson.fromJson(s,entityClass);
            success(t);

        } catch (Exception e) {
            failure(1001);
            e.printStackTrace();
        }




    }

    @Override
    public void onError(Throwable e) {
        try {
            if(e != null){
                if(e instanceof HttpException){
                    failure(HTTP_ERROR);
                } else if(e instanceof SocketException){
                    failure(NET_WORK_ERROR);
                }else {
                    failure(UNKNOW_ERROR);
                }
            }else {
                failure(UNKNOW_ERROR);
            }
            e.printStackTrace() ;
        } catch (Exception e1) {
            failure(UNKNOW_ERROR);
            e1.printStackTrace();
        }


    }

    @Override
    public void onComplete() {

    }


    //

    /**
     * code
     *  1000 UNKNOW_ERROR 未知错误
     *  1001 json 转化异常  parse error
     *  1002 当前网络不可用     java.net.SocketException: Network is unreachable  超时
     *  1003 服务器不可用 401 402 403 500 502 503 504
     * @param code
     */

    public static final int UNKNOW_ERROR = 1000;
    public static final int JSON_FORMAT_ERROR = 1001;
    public static final int NET_WORK_ERROR = 1002;
    public static final int HTTP_ERROR = 1003;


    public abstract void success(T t);
    public abstract void failure(int code);

    public abstract void onNextLog(LoginBean bean);
    public abstract void onNextReg(RegBean regBean);

}

      3,RetrofitManager

public class RetrofitManager {



    public static OkHttpClient client = new OkHttpClient.Builder()
            .build();

    public static  ApiService  apiService = new Retrofit.Builder()
           

       //这里是接口地址的域名
       .baseUrl("http://120.27.23.105/")

.addCallAdapterFactory(RxJava2CallAdapterFactory. create()) .addConverterFactory(ScalarsConverterFactory. create()) .client( client) .build() .create(ApiService. class) ; public static void get(String url , Map,String> map , Observer observer){ apiService.get(url ,map) .subscribeOn(Schedulers. io()) .observeOn(AndroidSchedulers. mainThread()) .subscribe(observer) ; } public static void post(String url ,Map,String> map ,Observer observer){ apiService.post(url ,map) .subscribeOn(Schedulers. io()) .observeOn(AndroidSchedulers. mainThread()) .subscribe(observer) ; }}

四，MVP框架

     1，登录

            登录的model层

public class LoginModel {
    //创建一个map集合
    Map,String> map=new HashMap<>();

    public void getData(String phone,String pwd,final loginCallBack loginCallBack){
        //将两个参数添加到map集合中
        map.put("mobile",phone);
        map.put("password",pwd);
        //使用封装进行请求数据，第一个参数为接口域名以后的部分，第二参数为map集合，第三个参数为回调接口
        RetrofitManager.get("user/login", map, new BaseObserver() {
            @Override
            public void success(LoginBean loginBean) {
                loginCallBack.success(loginBean);
            }

            @Override
            public void failure(int code) {

            }

            @Override
            public void onNextLog(LoginBean bean) {

            }

            @Override
            public void onNextReg(RegBean regBean) {

            }

        });
    }
    //创建model层的回调接口
    public interface loginCallBack{
        void success(LoginBean loginBean);
        void error(Exception e);
    }
}

        登录的view层

    

public interface LoginIview {
    void success(LoginBean loginBean);
    void error(String e);
    String getPhone();
    String getPwd();
}

     登录的presenter层

public class LoginPresenter {
    LoginModel loginModel;
    LoginIview loginIview;

    public LoginPresenter(LoginIview loginIview) {
        this.loginIview = loginIview;
        this.loginModel = new LoginModel();
    }

    public void getDatas(){
        String phone = loginIview.getPhone();
        String pwd = loginIview.getPwd();
        loginModel.getData(phone,pwd,new LoginModel.loginCallBack() {
            @Override
            public void success(LoginBean loginBean) {
                //这里进行了登录判断，是否可以正确跳转
                if(loginBean.getMsg().length()==4){
                    loginIview.success(loginBean);
                }else{
                    loginIview.error(loginBean.getMsg());
                }


            }

            @Override
            public void error(Exception e) {
               // loginIview.error();
            }
        });
    }
}

2，注册

   注册的model层

public class RegModel {
    Map,String> map=new HashMap<>();

    public void getData(String phone,String pwd,final RegCallBack regCallBack){

        map.put("mobile",phone);
        map.put("password",pwd);
        //http://120.27.23.105/user/reg
        RetrofitManager.get("user/reg", map, new BaseObserver() {
            @Override
            public void success(RegBean regBean) {
                regCallBack.success(regBean);
            }

            @Override
            public void failure(int code) {

            }

            @Override
            public void onNextLog(LoginBean bean) {

            }

            @Override
            public void onNextReg(RegBean regBean) {

            }

        });
    }

    public interface RegCallBack{
        void success(RegBean regBean);
        void error(Exception e);
    }
}

注册的view层

public interface RegIview {
    void success(RegBean regBean);
    void error(Exception e);
    String getPhone();
    String getPwd();
}

注册的presenter层

   

public class RegPresenter {
    RegModel regModel;
    RegIview regIview;

    public RegPresenter(RegIview regIview) {
        this.regIview = regIview;
        this.regModel = new RegModel();
    }

    public void getDatas(){
        String phone = regIview.getPhone();
        String pwd = regIview.getPwd();
        regModel.getData(phone,pwd,new RegModel.RegCallBack() {
            @Override
            public void success(RegBean regBean) {
                regIview.success(regBean);
            }

            @Override
            public void error(Exception e) {
                regIview.error(e);
            }
        });
    }
}

  五，     Activity

    找控件使用了第三方的butterknife,这是依赖，使用特别简单，可以查到

compile 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

  

1，登录activity

public class MainActivity extends AppCompatActivity implements LoginIview {
    @BindView(R.id.phone)
    EditText phone;
    @BindView(R.id.password)
    EditText password;
    @BindView(R.id.login)
    Button login;
    @BindView(R.id.reg)
    Button reg;
    @BindView(R.id.activity_main)
    LinearLayout activityMain;
    private LoginPresenter loginPresenter;
   // private String str;

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

        //实例化P
        loginPresenter = new LoginPresenter(this);

        //初始化适配器
    }

    @Override
    public void success(LoginBean loginBean) {
       // str = loginBean.getMsg().toString()+loginBean.getCode().toString();
        startActivity(new Intent(MainActivity.this, LieBiaoActivity.class));
        Toast.makeText(this, loginBean.getMsg(), Toast.LENGTH_SHORT).show();
    }

    @Override
    public void error(String e) {
        Toast.makeText(this, e, Toast.LENGTH_SHORT).show();
    }

    @Override
    public String getPhone() {
        return phone.getText().toString();
    }

    @Override
    public String getPwd() {
        return password.getText().toString();
    }

    @OnClick({R.id.login, R.id.reg})
    public void onViewClicked(View view) {
        switch (view.getId()) {
            case R.id.login:
                loginPresenter.getDatas();
               /* if (str.length()>6){
                    Toast.makeText(this, str, Toast.LENGTH_SHORT).show();
                }*/

                break;
            case R.id.reg:
                startActivity(new Intent(MainActivity.this, RegActivity.class));
                break;
        }
    }
}

   2，注册的activity

public class RegActivity extends AppCompatActivity implements RegIview{

    @BindView(R.id.phone)
    EditText phone;
    @BindView(R.id.password)
    EditText password;
    @BindView(R.id.reg)
    Button reg;
    @BindView(R.id.activity_main)
    LinearLayout activityMain;
    private RegPresenter regPresenter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_reg);
        ButterKnife.bind(this);
        //实例P
        regPresenter = new RegPresenter(this);


    }

    @OnClick(R.id.reg)
    public void onViewClicked() {
        regPresenter.getDatas();
    }

    @Override
    public void success(RegBean regBean) {
        Toast.makeText(this, regBean.getMsg().toString()+regBean.getCode().toString(), Toast.LENGTH_SHORT).show();
    }

    @Override
    public void error(Exception e) {

    }

    @Override
    public String getPhone() {
        return phone.getText().toString();
    }

    @Override
    public String getPwd() {
        return password.getText().toString();
    }
}
