Hello, I want use code in drawMetaball method for custom my widgets, but the caculations is too hard. Can you provide me some clues or geometric drawing? Thank you.

Hello, ltvu93. The code itself is pretty much self documented. The best way to understand it to use in your project is by passing your own parameters to drawMetaball method, i.e. canvas: Canvas, paint: Paint, path: Path, circle1: RectF, circle2: RectF, topBorder: Float, riseDistance: Float, maxDistance: Float, cornerRadius: Float, topSpreadFactor: Float, bottomStartSpreadFactor: Float, bottomEndSpreadFactor: Float, handleRate: Float

You will see how it behaves, so it will be easier to understand the logic of it.
