I want to know what methods do I use to implement “Flick” and “Drag” gestures in Touch mode

I do not know what a “flick” gesture is. More importantly, I have not worked with this sort of low-level touch gesture in several years.

one more concept I want to know is “Checkstyle” – I want it’s implementation in android project

I have not used this in an Android project. If I wanted to use it, I would be working off of resources like this and this.

I am sorry that I did not have more recent personal experience with these concepts!
