ElasticViews

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

Including in your project

Gradle

Add codes below 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:2.1.0"
}

SNAPSHOT

Snapshots of the current development version of ElasticViews are available, which track the latest versions.

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.

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" />

ElasticFloatingActionButton

<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();
        }
    };
