Carousel Recyclerview

Create carousel effect in recyclerview with the CarouselRecyclerview in a simple way.

[Layout manager](./preview/lm.jpg)

Including in your project

Gradle

Add below codes to your root build.gradle file (not your module build.gradle file).

allprojects {
    repositories {
          mavenCentral()
    }
}

And add a dependency code to your module's build.gradle file.

dependencies {
   implementation 'com.github.sparrow007:carouselrecyclerview:1.2.5'
}

Usage

Basic Example for Kotlin

Here is a basic example of implementing carousel recyclerview in koltin files (activity or fragment) with attribute.

  binding.carouselRecyclerview.adapter = adapter
  binding.carouselRecyclerview.apply {
   set3DItem(true)
   setAlpha(true)
   setInfinite(true)
  }

Basic Example for XML

Here is a basic example of implementing carousel recyclerview in layout xml.

<com.jackandphantom.carouselrecyclerview.CarouselRecyclerview
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:id="@+id/carouselRecyclerview"/>

Property infinite and 3D on Item enabled	Property infinite and alpha on Item enabled

API Methods

Method	Description	Default
fun set3DItem(is3DItem: Boolean)	Make the view tilt according to their position, middle position does not tilt.	false
fun setInfinite(isInfinite: Boolean)	Create the loop of the given view means there is no start or end, but provided position in the interface will be correct.	false
fun setFlat(isFlat: Boolean)	Make the flat layout in the layout manager of the reyclerview	false
fun setAlpha(isAlpha: Boolean)	Set the alpha for each item depends on the position in the layout manager	false
fun setIntervalRatio(ratio: Float)	Set the interval ratio which is gap between items (views) in layout manager	0.5f (value of gap, it should in range (0.4f - 1f))
fun getCarouselLayoutManager(): CarouselLayoutManager	Get the carousel layout manager instance
fun getSelectedPosition(): Int	Get selected position from the layout manager	center view Position
fun setIsScrollingEnabled(isScrollingEnabled: Boolean)	Set scrolling disabled or enabled	true

## API Methods Usage

  val carouselRecyclerview = findViewById<CarouselRecyclerview>(R.id.recycler)
        carouselRecyclerview.adapter = adapter
        carouselRecyclerview.set3DItem(true)
        carouselRecyclerview.setInfinite(true)
        carouselRecyclerview.setAlpha(true)
        carouselRecyclerview.setFlat(true)
        carouselRecyclerview.setIsScrollingEnabled(true)

        val carouselLayoutManager = carouselRecyclerview.getCarouselLayoutManager()
        val currentlyCenterPosition = carouselRecyclerview.getSelectedPosition()

## Item Position Listener You can listen to the position whenever the scroll happens you will get notified about the position, following are codes for listener

   carouselRecyclerview.setItemSelectListener(object : OnSelected {
            override fun onItemSelected(position: Int) {
                //Cente item
            }
        })

Reflection ImageView

You see in the demo that there is a mirror image (reflection imageview), for this i already created custom imageview for this.

Use ReflectionImageView in xml layout and provide src

 <com.jackandphantom.carouselrecyclerview.view.ReflectionImageView
     android:layout_width="120dp"
     android:layout_height="120dp"
     android:scaleType="fitXY"
     android:src="@drawable/hacker"
    />

Reflection Layout

Now you can show reflection in more efficient way and 3x faster than ReflectionImageView see the codes below

<?xml version="1.0" encoding="utf-8"?>
<com.jackandphantom.carouselrecyclerview.view.ReflectionViewContainer
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    xmlns:android="http://schemas.android.com/apk/res/android"
    app:reflect_relativeDepth="0.5"
    app:reflect_gap="0dp"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    >
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/guypro"
        android:scaleType="fitXY"
        android:id="@+id/image" />
</com.jackandphantom.carouselrecyclerview.view.ReflectionViewContainer>

Notes about Reflection imageview

I would recommend you to use image loading library like Glide for loading image in reflection image for better performance
