Answer

Use these two POJO class ........

LoginData.class

public class LoginData {

    private String email;
    private String password;

    public LoginData(String email, String password) {
        this.email = email;
        this.password = password;
    }

    /**
     *
     * @return
     * The email
     */
    public String getEmail() {
        return email;
    }

    /**
     *
     * @param email
     * The email
     */
    public void setEmail(String email) {
        this.email = email;
    }

    /**
     *
     * @return
     * The password
     */
    public String getPassword() {
        return password;
    }

    /**
     *
     * @param password
     * The password
     */
    public void setPassword(String password) {
        this.password = password;
    }

}

LoginResult.class

public class LoginResult {

    private Boolean error;
    private String message;
    private Integer doctorid;
    private Boolean active;

    /**
     *
     * @return
     * The error
     */
    public Boolean getError() {
        return error;
    }

    /**
     *
     * @param error
     * The error
     */
    public void setError(Boolean error) {
        this.error = error;
    }

    /**
     *
     * @return
     * The message
     */
    public String getMessage() {
        return message;
    }

    /**
     *
     * @param message
     * The message
     */
    public void setMessage(String message) {
        this.message = message;
    }

    /**
     *
     * @return
     * The doctorid
     */
    public Integer getDoctorid() {
        return doctorid;
    }

    /**
     *
     * @param doctorid
     * The doctorid
     */
    public void setDoctorid(Integer doctorid) {
        this.doctorid = doctorid;
    }

    /**
     *
     * @return
     * The active
     */
    public Boolean getActive() {
        return active;
    }

    /**
     *
     * @param active
     * The active
     */
    public void setActive(Boolean active) {
        this.active = active;
    }

}

Use API like this ....

 @POST("User/DoctorLogin")
    Call<String> getStringScalar(@Body LoginData body);

use call like this ....

 Call<LoginResult> call=service.getStringScalar(new LoginData(email,password));
    call.enqueue(new Callback<LoginResult>() {
                @Override
                public void onResponse(Call<LoginResult> call, Response<LoginResult> response) { 
               //response.body() have your LoginResult fields and methods  (example you have to access error then try like this response.body().getError() )

              }

                @Override
                public void onFailure(Call<LoginResult> call, Throwable t) {
           //for getting error in network put here Toast, so get the error on network 
                }
            });

EDIT:-

put this inside the success() ....

if(response.body().getError()){
   Toast.makeText(getBaseContext(),response.body().getMessage(),Toast.LENGTH_SHORT).show();


}else {
          //response.body() have your LoginResult fields and methods  (example you have to access error then try like this response.body().getError() )
                String msg = response.body().getMessage();
                int docId = response.body().getDoctorid();
                boolean error = response.body().getError();  

                boolean activie = response.body().getActive()();   
}
