Swiper

Android library for swiping views and fragments with default indicators and view transitions.

Usage

Import the library ('swiper') or aar file to your project.

In app/gradle.build

dependencies {
    implementation project(path: ':swiper')
}

minSdkVersion = '21'

Example

For views, use ViewAdapter.

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): Swiper.ViewHolder {
        val view = LayoutInflater.from(context).inflate(R.layout.view_item, parent, false)
        return Swiper.ViewHolder(view)
    }

    override fun onBindViewHolder(holder: Swiper.ViewHolder, position: Int) {
    	//Bind your view here
        }
    }

For fragments,

In MainActivity.kt

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val swiper: Swiper = findViewById(R.id.swiper)
	
        swiper.setAdapter(Swiper.FragmentAdapter(this, fragmentList))
        //swiper.setAdapter(ViewItemAdapter(this, itemList))

        //swiper.setIndicator(Swiper.DotIndicator(this))
        //swiper.setPageTransformer(Swiper.DepthPageTransformer())
    }

In activity_main.xml

    <com.losersclub.swiper.Swiper
        android:id="@+id/swiper"
        app:swiperPageTransformer="depthPageTransformer"
        app:swiperIndicatorActive="@drawable/dot_active"
        app:swiperIndicatorInactive="@drawable/dot_inactive"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        android:layout_width="0dp"
        android:layout_height="0dp"/>

Indicators

There are two default indicators: DotIndicator and BarIndicator

Dot Indicator

Custom Indicator

You can set your custom indicators in xml or in code.

I haven't tested other indicator libraries with update.

You can also use other opensource indicator libraries such as InkPageIndicator.

    inkPageIndicator.setViewPager(swiper.viewPager2);

Other awesome indicators are:

• SpringIndicator
• Jake Wharton's ViewPagerIndicator
• ExtensiblePageIndicator

Page Transformers

There are two default page transformers: DepthPageTransformer and ZoomOutPageTransformer

You can create your own page transformer as

class YourPageTransformer : ViewPager2.PageTransformer {
        override fun transformPage(view: View, position: Float) {
            view.apply {
	    	// Transform your page here
            }
        }
    }
