Touch Moviments in Android

Good Morning Forum users.
Recently started to migrate an application that use the Desktop for a tablet with android but am having difficulty in movements touch.
Could someone help me? or provide a simple code that uses touch movements?
Would you like simple things like dual touch, zoom in, zoom out.
I await response.
