How to use this library in your project?

First of all, add Koloda to the xml layout of your activity, so it looks like that:

<?xml version="1.0" encoding="utf-8"?>
<com.yalantis.library.Koloda
	android:id="@+id/koloda"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	app:koloda_card_layout="@layout/item_koloda" />

Create your adapter and set it to Koloda adapter

adapter = YourAdapter(data)
koloda.adapter = adapter

Customization

For customization ui Koloda you can use such attributes value :

To control the card position by scale lower cards set koloda_card_scale_diff attributes float value in layout. The range of ScaleDiff is 0.01 - 0.1. The default value for ScaleDiff is 0.04f

<com.yalantis.library.Koloda
	...	
        app:koloda_card_scale_diff="0.04" 
        ...
/>

To control distance between cards set value to koloda_card_offsetY in dp. The default value for CardOffsetY is 16dp.

 <com.yalantis.library.Koloda
 	...	
        app:koloda_card_offsetY="16dp" 
        ...
/>

Change angle for card when swipe it you can set value to koloda_card_rotate_angle. The default value for CardRotateAngle is 30

<com.yalantis.library.Koloda
	...	
        app:koloda_card_rotate_angle="30"
        ...
/>

Also you can change visible cards count in desk with koloda_max_visible_cards attributes. The default value for CardsVisible is 3

<com.yalantis.library.Koloda
	...	
        app:koloda_max_visible_cards="3"
        ...
/>

Koloda has reloadPreviousCard() method which reload previous card

koloda.reloadPreviousCard()

Koloda has reloadAdapterData() method which reload all data(Start show data from the beginning)

koloda.reloadAdapterData() 

Also, you can realize automatic swipe using onButtonClicks(isSwipeCardToRight: Boolean) method:

koloda.onButtonClick(false) - swipe to left
koloda.onButtonClick(true) - swipe to right

Also you can create KolodaListener and use all the methods of the KolodaListener. This interface provides empty implementations of the methods. For any custom animation callback handle you can create any custom listener that cares only about a subset of the methods of this listener can simply implement the interface directly:

onNewTopCard(position: Int)
onCardDrag(position: Int, cardView: View, progress: Float)
onCardSwipedLeft(position: Int)
onCardSwipedRight(position: Int)
onClickRight(position: Int)
onClickLeft(position: Int)
onCardSingleTap(position: Int)
onCardDoubleTap(position: Int)
onCardLongPress(position: Int)
onEmptyDeck()
