ElasticViews


An easy way to implement elastic touch effect for Android.

Including in your project

build.gradle

Add below codes to your root build.gradle file (not your module build.gradle file).

repositories {
    jcenter()
}

dependencies {
    implementation "com.github.skydoves:elasticviews:2.0.3"
}

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, etc. If not, nothing happens.

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

or use butterknife

@OnClick(R.id.elasticbutton)
public void onClick(View v) {
    // do something
} 

ElasticButton

<com.skydoves.elasticviews.ElasticButton
      android:id="@+id/elasticbutton"
      android:layout_width="match_parent"
      android:layout_height="50dp"
      app:button_backgroundColor="#30354b"
      app:button_round="20"
      app:button_scale="0.7"
      app:button_duration="400"
      app:button_labelText="Elastic Button"
      app:button_labelColor="#ffffff"
      app:button_labelSize="16"
      app:button_labelStyle="bold"/>

ElasticButton use like TextView

If button_backgroundColor attribute be set as @android:color/transparent, it will looks like a TextView.

app:button_backgroundColor="@android:color/transparent"

ElasticCheckButton

<com.skydoves.elasticviews.ElasticCheckButton
      android:id="@+id/elasticcheckbutton"
      android:layout_width="match_parent"
      android:layout_height="50dp"
      app:checkbutton_backgroundColor="#30354b"
      app:checkbutton_round="30"
      app:checkbutton_scale="0.9"
      app:checkbutton_duration="400"
      app:checkbutton_labelText="Elastic CheckButton"
      app:checkbutton_labelColor="#ffffff"
      app:checkbutton_labelSize="16"
      app:checkbutton_labelStyle="bold"
      app:checkbutton_alpha="0.5"
      app:checkbutton_ischecked="false"/>

ElasticImageView

<com.skydoves.elasticviews.ElasticImageView
      android:id="@+id/elasticimageview"
      android:layout_width="64dp"
      android:layout_height="64dp"
      android:scaleType="fitXY"
      android:src="@drawable/ic_question"
      app:imageview_duration="500"
      app:imageview_scale="0.7"/>

ElasticFloatingButton

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

ElasticLayout

ElasticLayout implements elastic animation to all child views.

<com.skydoves.elasticviews.ElasticLayout
      android:id="@+id/elasticlayout"
      android:layout_width="match_parent"
      android:layout_height="80dp"
      app:layout_backgroundColor="#30354b"
      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>

ElasticAnmimation

ElasticAnimation implements elastic animations for android views or 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();
        }
    };
