✨ An easy way to implement an elastic touch effect for Android.
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" }
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/' } }ElasticViews lets we use like using normal views and gives all of the Views or GroupViews touch effect very simply.
First add below XML Namespace inside your XML layout file.
xmlns:app="http://schemas.android.com/apk/res-auto"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 } });<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" /><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" /><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" /><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" /><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 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 implements elastic animations for android views and view groups.
new ElasticAnimation(clickedView).setScaleX(0.9f).setScaleY(0.9f).setDuration(400) .setOnFinishListener(onFinishListener).doAction();
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 } });ElasticAnimation supports kotlin extension elasticAnimation.
val anim = textView.elasticAnimation(0.8f, 0.8f, 400, object: ElasticFinishListener { override fun onFinished() { // do anything } }) anim.doAction()elasticAnimation(this) { setDuration(duration) setScaleX(scale) setScaleY(scale) setOnFinishListener(object : ElasticFinishListener { override fun onFinished() { onClick() } }) }.doAction()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(); } }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(); } };Support it by joining stargazers for this repository. ⭐
