设置REST API不工作时服务器响应的日期格式

Question

private String formatDate(String dateString) {
    try {
        SimpleDateFormat sd = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS" );
        Date d = sd.parse(dateString);
        sd = new SimpleDateFormat("dd/MM/yyyy");
        return sd.format(d);
    } catch (ParseException e) {
    }
    return "";
}

public void getProfile() {

    Retrofit retrofit = RetrofitClient.getClient(authUser.getToken());
    APIService mAPIService = retrofit.create(APIService.class);

    mAPIService.getProfile("Bearer " + authUser.getToken()).enqueue(new Callback<Profile>() {
        @Override
        public void onResponse(Response<Profile> response, Retrofit retrofit) {
            if(response.isSuccess()) {
                try {
                    String loginSuccess = response.body().getSuccess();
                    if (loginSuccess.equals("true")) {
                        id_name.setText(response.body().getData().getName());
                        id_email.setText(response.body().getData().getEmail());
                        phone_input_layout.setText(response.body().getData().getPhoneNumber());
                        id_gender.setText(response.body().getData().getGender());
                        String dateOfBirth = response.body().getData().getDateOfBirth();
                        id_date_of_birth.setText(formatDate(dateOfBirth));
                        //updateLabel(dateOfBirth);
                        id_residential_address.setText(response.body().getData().getResidentialAddress());
                        if (response.body().getData().getEmploymentStatus().equals("Student")) {
                            id_nss_number.setVisibility(View.VISIBLE);
                            maximum_layout.setVisibility(View.INVISIBLE);
                            extended_layout.setVisibility(View.INVISIBLE);
                        } else if (response.body().getData().getEmploymentStatus().equals("Employed")) {
                            maximum_layout.setVisibility(View.VISIBLE);
                            extended_layout.setVisibility(View.INVISIBLE);
                            id_nss_number.setVisibility(View.INVISIBLE);
                            id_type.setText(response.body().getData().getIdType());
                            id_number.setText(response.body().getData().getIdNumber());
                            id_expiry_date.setText(response.body().getData().getIdExpiryDate());
                        }


                    } else {
                        String message = response.body().getMessage();
                        Log.e("getProfileError", message);
                        Toast.makeText(UserProfileActivity.this, message, Toast.LENGTH_LONG).show();
                    }
                }catch (Exception e){
                    Toast.makeText(getApplicationContext(), "Some fields are empty", Toast.LENGTH_SHORT).show();
                    e.printStackTrace();
                }

            }


        }

        @Override
        public void onFailure(Throwable throwable) {
            Log.e("getProfileError", throwable.getMessage());
            Toast.makeText(UserProfileActivity.this, "Unable to Login, Please Try Again", Toast.LENGTH_LONG).show();
        }
    });
}

这是我从日期格式得到的例外情况

I/dateError:: Unparseable date: "1988-11-09T00:00:00Z"

Answer 1

您所需的格式为

yyyy-MM-dd'T'HH:mm:ss.SSS'Z' 

最后一个Z代表“零时偏移”也称为“祖鲁时间”(UTC)。

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.US);
format.setTimeZone(TimeZone.getTimeZone("UTC"));

使用此UTC时区，转换后的小时将为20h。
