想把onResponse里返回的response.body的值保存在bundle里，让我能在其他的Activity里使用，但在OnResponse里赋值后出来结果都为空，想知道怎么调用返回的值

public void loginUser(String email,String password){
    API api = RetrofitCreator.getInstance().getRetrofit().create(API.class);
    Call<Users> task = api.loginUser(email,password);
    task.enqueue(new Callback<Users>() {
        @Override
        public void onResponse(Call<Users> call, Response<Users> response) {
            Log.d(TAG,"response -- > " + response.code());
            if (response.code() == HttpsURLConnection.HTTP_OK){
                Users users = response.body();//返回的值
                
            }
        }

        @Override
        public void onFailure(Call<Users> call, Throwable t) {
            Log.d(TAG,"exception -- > " + t.toString());
        }
    });
}
