Please refer to the screenshot images attached, The below image 
shows Google Pay app.There is only 1 axis and the circle button can slide along that axis only.
What I require is 3 axes( as T or Y as seen in the second image) and a circle button that can slide along all those axes.
I understand this can be done using Custom View in Android.
However, I need help in writing a custom algorithm to define the motion of the circle button along those axes.`

thank you I see the merit of using a parametric equation, currently using an onclickDragListener now to move the circle, not sure how we can ' guide' the movement of the circle based on an equation ? Is there a certain method/ function that I'm missing ?

yes: you need a custom view - there is no existing view that could be used for what you want
