简单登录注册

1：使用泛型接口

public class ILogin<T> {
    private String message;
    private String status;
    private T result;

    public String getMessage() {
        return message;
    }

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

    public String getStatus() {
        return status;
    }

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

    public T getResult() {
        return result;
    }

    public void setResult(T result) {
        this.result = result;
    }
}

2：接口

@Entity
public class Login {
        /**
         * headPic : http://172.17.8.100/images/small/head_pic/2018-12-20/20181220194510.jpg
         * nickName : 35_N3B12
         * phone : 17701283117
         * sessionId : 1546066355444107
         * sex : 1
         * userId : 107
         */
        private String headPic;
        private String nickName;
        private String phone;
        private String sessionId;
        private int sex;
        @Id
        private int userId;
        @Generated(hash = 1912988326)
        public Login(String headPic, String nickName, String phone, String sessionId, int sex,
                int userId) {
            this.headPic = headPic;
            this.nickName = nickName;
            this.phone = phone;
            this.sessionId = sessionId;
            this.sex = sex;
            this.userId = userId;
        }
        @Generated(hash = 1827378950)
        public Login() {
        }
        public String getHeadPic() {
            return this.headPic;
        }
        public void setHeadPic(String headPic) {
            this.headPic = headPic;
        }
        public String getNickName() {
            return this.nickName;
        }
        public void setNickName(String nickName) {
            this.nickName = nickName;
        }
        public String getPhone() {
            return this.phone;
        }
        public void setPhone(String phone) {
            this.phone = phone;
        }
        public String getSessionId() {
            return this.sessionId;
        }
        public void setSessionId(String sessionId) {
            this.sessionId = sessionId;
        }
        public int getSex() {
            return this.sex;
        }
        public void setSex(int sex) {
            this.sex = sex;
        }
        public int getUserId() {
            return this.userId;
        }
        public void setUserId(int userId) {
            this.userId = userId;
        }

}

3：使用接口拼接
创建一个类

public class StringUrl {
 /**
     * 登录注册
     */
    public static final String LOGIN_URL="http://172.17.8.100/small/user/v1/";

}

4：接口拼接类

public interface ApiService {
    /**
     * 登录
     * @param phone
     * @param pwd
     * @return
     */
    @POST("login")
    @FormUrlEncoded
    Observable<ILogin<Login>> getlogin(@Field("phone") String phone,@Field("pwd")String pwd);

    /**
     * 注册
     * @param phone
     * @param pwd
     * @return
     */
    @POST("register")
    @FormUrlEncoded
    Observable<ILogin<Login>> getregister(@Field("phone") String phone,@Field("pwd") String pwd);
    }

5：工具类LoginOkHttpUtils

public class LoginOkHttpUtils {
    private static LoginOkHttpUtils instance;
    private Retrofit retrofit;
    public LoginOkHttpUtils(){
        init();
    }
    public static LoginOkHttpUtils getInstance(){
        if (instance ==null){
            instance = new LoginOkHttpUtils();
        }
        return instance;
    }

    private void init() {
        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BASIC);
        OkHttpClient client = new OkHttpClient.Builder()
                .addInterceptor(loggingInterceptor)
                .build();
        retrofit = new Retrofit.Builder()
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .baseUrl(StringUrl.LOGIN_URL)
                .client(client)
                .build();
    }
    //把接口的注解翻译为OKhttp请求
    public <T> T create(final Class<T> service) {
        return retrofit.create(service);
    }
}

6：登录布局

7：抽取基类

public abstract class BaseActvity extends AppCompatActivity {


    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(getcontentview());
        initView();
        initData();
    }

    /**
     * 初始化数据
     */
    public abstract void initData();

    /**
     * 初始化控件
     */
    public abstract void initView();

    /**
     * 初始化布局
