# ElasticViews
✨ An easy way to implement an elastic touch effect for Android.
## Including in your project
[](https://search.maven.org/search?q=g:%22com.github.skydoves%22%20AND%20a:%22elasticviews%22)
[](https://jitpack.io/#skydoves/ElasticViews)
#### Gradle
Add codes below to your **root** `build.gradle` file (not your module build.gradle file).
```gradle
allprojects {
repositories {
mavenCentral()
}
}
```
And add a dependency code to your **module**'s `build.gradle` file.
```gradle
dependencies {
implementation "com.github.skydoves:elasticviews:2.1.0"
}
```
## SNAPSHOT
[](https://oss.sonatype.org/content/repositories/snapshots/com/github/skydoves/elasticviews/)
Snapshots of the current development version of ElasticViews are available, which track [the latest versions](https://oss.sonatype.org/content/repositories/snapshots/com/github/skydoves/elasticviews/).
```Gradle
repositories {
maven { url 'https://oss.sonatype.org/content/repositories/snapshots/' }
}
```
## Usage
`ElasticViews` lets we use like using normal views and gives all of the Views or GroupViews touch effect very simply.
#### Add XML Namespace
First add below XML Namespace inside your XML layout file.
```gradle
xmlns:app="http://schemas.android.com/apk/res-auto"
```
#### OnClick Method
All of ElasticViews should be set `OnClickListener` or `onClick` method. If not, nothing happens.
```java
ElasticButton elasticButton = (ElasticButton)findViewById(R.id.elasticbutton);
elasticButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// do something
}
});
```
### ElasticButton
```gradle
```
### ElasticCheckButton
```gradle
```
### ElasticImageView
```gradle
```
### ElasticFloatingActionButton
```gradle
```
### ElasticCardView
```gradle
...
```
### ElasticLayout
ElasticLayout gives elastic animation to all child views.
```gradle
```
### ElasticAnimation
ElasticAnimation implements elastic animations for android views and view groups.
```java
new ElasticAnimation(clickedView).setScaleX(0.9f).setScaleY(0.9f).setDuration(400)
.setOnFinishListener(onFinishListener).doAction();
```
#### ViewPropertyAnimatorListener
we can set `ViewPropertyAnimatorListener` using `setListener` method and detect animation's status.
```java
.setListener(new ViewPropertyAnimatorListener() {
@Override
public void onAnimationStart(View view) {
// do something
}
Override
public void onAnimationEnd(View view) {
finishListener.onFinished();
}
Override
public void onAnimationCancel(View view) {
// do something
}
});
```
#### Kotlin Extension
ElasticAnimation supports kotlin extension `elasticAnimation`.
```kotlin
val anim = textView.elasticAnimation(0.8f, 0.8f, 400, object: ElasticFinishListener {
override fun onFinished() {
// do anything
}
})
anim.doAction()
```
#### Kotlin dsl
```kotlin
elasticAnimation(this) {
setDuration(duration)
setScaleX(scale)
setScaleY(scale)
setOnFinishListener(object : ElasticFinishListener {
override fun onFinished() {
onClick()
}
})
}.doAction()
```
#### Example : Normal Button
we can implement animation on all of the views like below.
```java
@OnClick(R.id.button)
public void addNewAlarm(View v){
// implements animation uising ElasticAnimation
new ElasticAnimation(v).setScaleX(0.85f).setScaleY(0.85f).setDuration(500)
.setOnFinishListener(new ElasticFinishListener() {
@Override
public void onFinished() {
// Do something after duration time
}
}).doAction();
}
}
```
#### Example : ListView Item
So also we can implement animation on listView's items like below.
```java
private class ListViewItemClickListener implements AdapterView.OnItemClickListener {
@Override
public void onItemClick(AdapterView adapterView, View clickedView, final int pos, long id) {
new ElasticAnimation(clickedView).setScaleX(0.9f).setScaleY(0.9f).setDuration(400)
.setOnFinishListener(new ElasticFinishListener() {
@Override
public void onFinished() {
// Do something after duration time
Toast.makeText(getBaseContext(), "ListViewItem" + pos, Toast.LENGTH_SHORT).show();
}
}).doAction();
}
};
```
