# ElasticView

![Download](https://api.bintray.com/packages/armcha/maven/ElasticView/images/download.svg)
[![API](https://img.shields.io/badge/API-21%2B-brightgreen.svg?style=flat)](https://android-arsenal.com/api?level=21)
[![Android Arsenal](https://img.shields.io/badge/Android%20Arsenal-ElasticView-brightgreen.svg?style=flat)](https://android-arsenal.com/details/1/7274)

Elastic view is a regular **CardView**, which can **flex** from user touches💪

**Kotlin** ❤️  

![](screens/third.gif)

Let's see it in action 💻📲


![](screens/first.gif)
![](screens/second.gif)

### Download sample [apk](https://github.com/armcha/ElasticView/raw/master/screens/sample.apk) :arrow_down:

The current minSDK version is API level 21.
### Download 

Gradle:
```groovy
implementation 'com.github.armcha:ElasticView:0.2.0'
```

## Setup and usage
You can use it as a regualar CardView.

```xml
 <io.armcha.elasticview.ElasticView
        android:id="@+id/imageElasticView"
        android:layout_width="..."
        android:layout_height="..."
        app:cardCornerRadius="10dp"
        app:cardElevation="5dp">
  
        <ChildView.../>
        <!--or without childView-->
  
</io.armcha.elasticview.ElasticView>
```

## Customization
For now, you can only change flexibility for the view

from code

```kotlin
elasticView.flexibility = 8f
```

or from xml

```xml
 <io.armcha.elasticview.ElasticView
        android:id="@+id/imageElasticView"
        android:layout_width="..."
        android:layout_height="..."
        app:flexibility="7"
        app:cardCornerRadius="10dp"
        app:cardElevation="5dp"/>
```

**Note the flexibility must be between [1f..10f] ❗️**


That's all :ok_hand:
