#Usage When launching another activity,specify the views where you want to perform transition and pass it as a bundle. The launching activity and the launched activity should have common views to perform transition on that pair of views.

 Intent intent=new Intent(mContext, DetailActivity.class);
  ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(MainActivity.getInstance(),
Pair.create((View) cover, "cover"));
  mContext.startActivity(intent,options.toBundle());

Specify the attribute android:transitionName="cover" in both the view of two activities.Transition framework will look for the views with same transitionName attribute and will apply the auto transition on them.

We will specify the transition in our theme. Add this attribute to your v21 theme

<item name="android:windowSharedElementEnterTransition">@transition/shared_element</item>

We will define our own custom Transition instead of the default Transition. #####res/transition/shared_element.xml

<?xml version="1.0" encoding="utf-8"?> <!-- --A set of transitions on two views performed together <!-- --> <transitionSet
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:transitionOrdering="together"
  android:duration="240">

<transitionSet
>
  <!-- --A custom transition defined in PlayTransition class <!-- -->

<transition

 class="com.naman14.playanimations.PlayTransition"/>

<targets>

 <!-- --We are excluding the second view from the custom transition <!-- -->

 <target android:excludeId="@id/icon" /> />

</targets>

</transitionSet> <!-- --We have left this one upto transition Framework <!-- -->
  <autoTransition/>  </transitionSet>
