how to make swipe keyboard like app [closed]

Answer 1

The problem is two-fold:

1- Implementing a custom keyboard. This question has been asked before here, but you can check out this post with some sample code: http://www.fampennings.nl/maarten/android/09keyboard/index.htm

2- Implementing the swipe gesture. This is even more complicated, as you would have to create your onTouchListener, and draw some kind of animation when the screen is touched. You could start here

Answer 2

Well, since I helped write Swype I'll give you a bit of help here. You're going to need to spend a lot of time studying DSP (digital signal processing) to understand how to evaluate the incoming touch data and figure out where letters are (this is more complicated than you think, because people don't Swype cleanly letter to letter- they loop and curl). The algorithms behind Swype were the end result of over a decade of research by our founder.
