nice video,do u have a git of this project?

[@kazumanaka9220]

Thank you for this tutorial video. It's helped me a lot. After watched the video,I was struggling to assign the touch event to only the switch. I solved it like this. If (rect.top< point.y && rect.bottom>point.y && rect.right < point.x){ gestureDetector.onTouchEvent(event) } Anyway thanks for the video. I really like your approach!
