贴心吧。哈哈哈哈哈哈       哈

生成实体bean：

public class UserBean {    private String msg;    private String code;    private DataEntity data;    public static UserBean objectFromData(String str) {        return new com.google.gson.Gson().fromJson(str, UserBean.class);    }    public void setMsg(String msg) {        this.msg = msg;    }    public void setCode(String code) {        this.code = code;    }    public void setData(DataEntity data) {        this.data = data;    }    public String getMsg() {        return msg;    }    public String getCode() {        return code;    }    public DataEntity getData() {        return data;    }    public static class DataEntity {                private Object age;        private String appkey;        private String appsecret;        private String createtime;        private Object email;        private Object gender;        private Object icon;        private String mobile;        private Object money;        private Object nickname;        private String password;        private String token;        private int uid;        private String username;        public static DataEntity objectFromData(String str) {            return new com.google.gson.Gson().fromJson(str, DataEntity.class);        }        public void setAge(Object age) {            this.age = age;        }        public void setAppkey(String appkey) {            this.appkey = appkey;        }        public void setAppsecret(String appsecret) {            this.appsecret = appsecret;        }        public void setCreatetime(String createtime) {            this.createtime = createtime;        }        public void setEmail(Object email) {            this.email = email;        }        public void setGender(Object gender) {            this.gender = gender;        }        public void setIcon(Object icon) {            this.icon = icon;        }        public void setMobile(String mobile) {            this.mobile = mobile;        }        public void setMoney(Object money) {            this.money = money;        }        public void setNickname(Object nickname) {            this.nickname = nickname;        }        public void setPassword(String password) {            this.password = password;        }        public void setToken(String token) {            this.token = token;        }        public void setUid(int uid) {            this.uid = uid;        }        public void setUsername(String username) {            this.username = username;        }        public Object getAge() {            return age;        }        public String getAppkey() {            return appkey;        }        public String getAppsecret() {            return appsecret;        }        public String getCreatetime() {            return createtime;        }        public Object getEmail() {            return email;        }        public Object getGender() {            return gender;        }        public Object getIcon() {            return icon;        }        public String getMobile() {            return mobile;        }        public Object getMoney() {            return money;        }        public Object getNickname() {            return nickname;        }        public String getPassword() {            return password;        }        public String getToken() {            return token;        }        public int getUid() {            return uid;        }        public String getUsername() {            return username;        }    }}

view层：

public interface ILoginView {    void setName(String name);    String getName();    void setPass(String pass);    String getPass();}

model层：

接口：

public interface ILoginModel {    void login(String name, String pass, Callback callback);    void reg(String name, String pass, Callback callback);}

实现类：

public class LoginModel implements ILoginModel {    @Override    public void login(String name, String pass, okhttp3.Callback callback) {        OkHttpUtils.getInstance().doGet("http://120.27.23.105/user/login?mobile="+name+"&password="+pass, (okhttp3.Callback) callback);    }    @Override    public void reg(String name, String pass, okhttp3.Callback callback) {    }}

presenter层：

public class LoginPresenter {    private Context context;    private ILoginModel model;    private ILoginView view;    public LoginPresenter(Context context, ILoginView view) {        this.context = context;        this.view = view;        model = new LoginModel();    }    public void login(){        String name = view.getName();        String pass = view.getPass();        model.login(name, pass, new OnUiCallback() {            @Override            public void onFailed(Call call, IOException e) {            }            @Override            public void onSuccess(String result) throws IOException {                Gson gson = new Gson();                UserBean userBean = gson.fromJson(result, UserBean.class);                String code = userBean.getCode();                Log.i("=========", "onSuccess: "+code);                if(code.equals("0")){                    Toast.makeText(context,"登录成功",Toast.LENGTH_SHORT).show();                    Intent intent = new Intent(context, InfoActivity.class);                    context.startActivity(intent);                }else{                    Toast.makeText(context,"登录失败",Toast.LENGTH_SHORT).show();                }            }        });    }}

有些其他的资源文件可能会报错，段友们一看就明白，或者直接删掉就可以了。哈哈哈啊哈哈哈哈啊哈            哈
