I have a Mifare Desfire EV1 Card which I am using as a Type 4A Tag. I want to read and then write to the Tag immediately without re-tapping after reading it. Is this possible to write an application in android to do such thing...Please help

Yes. Basically (NDEF) read is done by default by the Android subsystem, you can then select to write.

I've put up some templates here is you are interested, although you'd have to combine two of them to have the desired effect.
