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:2.1.0"
}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

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();
}
