Here's some Pseudo to help you along:

If (touch is pressed) and (player is colliding with ground)
DO
(jump action)

Basically, test if the player is touching the ground, and if so, allow jumping. Otherwise, don't. You'll need to add some other qualifiers to prevent weird behaviour with the BOTTOM of platforms if you can jump up and touch one, but that should get you started.
