LayoutManagers

1. CurveLayoutManager

A linear LayoutManger can scroll by any Curves.

Some default curve.

type	类型	code	sample	params
Snake	贪吃蛇	PathCurve...		row,col
FerrisWheel	摩天轮
Parabola	抛物线	x=i+0.5; y=0.2i^2+0.5		focus
Slash	斜线	x=i+0.5;y=slope*i+0.5		slope

How to custom your curve.

See Custom Tutorial.

Usage

Step1. Create your curve like this:

/** 抛物线 */
class Parabola(
    private val focus: Float = .2f
) : CurveLayoutManger.Curve {
    override fun getInterpolation(i: Float, position: CurveLayoutManger.Vector2) {
        position.x = i + 0.5f
        position.y = focus * i * i + 0.5f
    }
}

Step2. Set layoutManger like this:

recycler_view.layoutManager = CurveLayoutManger(Parabola())

Import

1. Add it in your root build.gradle at the end of repositories:

    allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }
   

2. Add the dependency in your module build.gradle:

    dependencies {
            implementation 'com.github.dyguests:LinLayoutManager:x.y.z'
    }
