Slider

This is an infinite auto sliding Slider library for Android built on top of Epoxy. You have all the benefits of Epoxy plus automatic and infinite sliding on top. Completely in Kotlin. Thanks to Epoxy you can use the power of Kotlin DSLs with this library too.

Slider is not bound to any particular view so you can use any type of view as long as it's a EpoxyModel.

Demo

Usage

Step 1

Add dependency to your build.gradles

Inside root level build.gradle

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

Inside App build.gradle

dependencies {
            implementation 'com.github.worldsnas:slider:{latest_version}'
}

Step 2

Add Slider to your epoxy models:

yourEpoxyView.withModels {
            slider {
                id("your slider id")
                
                //delay before every cycle if user is not scrolling
                cycleDelay(5_000)
                
                //controll the indicator visibility
                indicatorVisible(true)
                //Front/Selected indicator dot color (if indicator visible)
                indicatorSelectedDotColor(Color.YELLOW)
                //rest of indicator dot color (if indicator visible)
                indicatorDotColor(Color.BLACK)
                
                
                models(
                         // list of all the sliding models 
                         // don't forget to add Id for them
                )
            }
        }

To add infinite sliding you can use infinite(true). The only limitation for infinite scrolling is you need to add a copier function to the builder.

The complete slider builder with infinite scrolling will look like this:

yourEpoxyView.withModels {
            slider {
                id("your slider id")
                cycleDelay(5_000)
                
                indicatorVisible(true)
                indicatorSelectedDotColor(Color.YELLOW)
                indicatorDotColor(Color.BLACK)
                
                models(
                         banners.mapIndexed { index, s ->
                            BannerViewModel_().apply {
                                id(index.toLong())
                                bindImage(s)
                                listener {
                                    showImageUrl(it)
                                }
                            }
                        }
                )
                
                infinite(true)
                copier { oldModel ->
                    oldModel as BannerViewModel_
                    //you have to create a new object and return here
                    BannerViewModel_().apply {
                        id(oldModel.id())
                        bindImage(banners[oldModel.id().toInt()])
                        listener { imageUrl ->
                            showImageUrl(imageUrl)
                        }
                    }
                }
            }
        }

Now run your application!
