Get Response in one step

Sometimes when I sent an APDU command to card, it responded 61 XX which meant there were a response with XX length and I should send another APDU command to get it.
My question is, how can I get the response immediately? Or how can I get it by one step? Thanks a lot for any help.

you can send command of the "get response",the format of the command is 00C00000XX,XX is length.

Thanks for your help, wumindejia.
But what can I do to avoid this way(2 steps) to get response? I want to get the response at once(1 step).

Did your card support T=1 protocol? You can connect your card via T=1, this case doesn't need you to send get response command.
