ElasticViews

✨ An easy way to implement an elastic touch effect for Android.

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.skydoves:elasticviews:2.0.9" }

## 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.

ElasticButton elasticButton = (ElasticButton)findViewById(R.id.elasticbutton);
elasticButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // do something
    }
});

ElasticButton

<com.skydoves.elasticviews.ElasticButton
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:text="Elastic Button"
   android:textColor="@android:color/white"
   android:textSize="17sp"
   app:button_cornerRadius="4dp"
   app:button_duration="250"
   app:button_scale="0.87" />

ElasticCheckButton

<com.skydoves.elasticviews.ElasticCheckButton
   android:layout_width="match_parent"
   android:layout_height="45dp"
   android:background="#30354b"
   android:text="Text"
   android:textColor="@android:color/white"
   android:textStyle="bold"
   app:checkButton_cornerRadius="4dp"
   app:checkButton_alpha="0.7"
   app:checkButton_duration="400"
   app:checkButton_scale="0.9" />

ElasticImageView

<com.skydoves.elasticviews.ElasticImageView
   android:layout_width="23dp"
   android:layout_height="23dp"
   android:scaleType="fitXY"
   android:src="@drawable/ic_question"
   android:tint="#3d95c9"
   app:imageView_scale="0.7"
   app:imageView_duration="300" />

ElasticFloatingButton

<com.skydoves.elasticviews.ElasticFloatingActionButton
   android:layout_width="64dp"
   android:layout_height="64dp"
   android:src="@drawable/ic_add"
   android:tint="#ffffff"
   app:fabSize="normal"
   app:fabutton_duration="400"
   app:fabutton_scale="0.85" />

ElasticCardView

<com.skydoves.elasticviews.ElasticCardView
  android:layout_width="match_parent"
  android:layout_height="120dp"
  app:cardCornerRadius="8dp"
  app:cardElevation="12dp"
  app:cardBackgroundColor="@color/background"
  app:cardView_duration="250"
  app:cardView_scale="0.8" >

  ...

</com.skydoves.elasticviews.ElasticCardView>

ElasticLayout

ElasticLayout gives elastic animation to all child views.

<com.skydoves.elasticviews.ElasticLayout
  android:layout_width="match_parent"
  android:layout_height="80dp"
  app:layout_cornerRadius="4dp"
  app:layout_duration="500"
  app:layout_scale="0.85">

  <TextView
      android:id="@+id/textView0"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:text="This is"
      android:textColor="#ffffff"
      android:textSize="18sp" />

  <TextView
      android:layout_below="@+id/textView1"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_alignParentBottom="true"
      android:text="ElasticLayout"
      android:textColor="#ffffff"
      android:textSize="18sp"
      android:gravity="end" />
</com.skydoves.elasticviews.ElasticLayout>

ElasticAnimation

ElasticAnimation implements elastic animations for android views and view groups.

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.

.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.

val anim = textView.elasticAnimation(0.8f, 0.8f, 400, object: ElasticFinishListener {
    override fun onFinished() {
        // do anything
    }
})
anim.doAction()

Kotlin dsl

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.

@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.

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();
        }
    };
