Android shared element transition does not work

Question

I have 2 Activities each having an ImageView.First one has an image which upon clicked should do the transition magic while moving to the next activity.It goes to the next activity,but for some strange reason transition is not working.

Activity2 Screenshot

Activity1.java:

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP)
                {
                    Intent intent =new Intent(Activity1.this,Activity2.class);
                    ActivityOptionsCompat activityOptions=ActivityOptionsCompat.
                            makeSceneTransitionAnimation(Activity1.this,imageView,"shift");

                    ActivityCompat.startActivity(Activity1.this,intent,activityOptions.toBundle());
                }

activity1.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent">
<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/img"
    android:layout_centerHorizontal="true"
    android:background="@drawable/th"
    android:transitionName="shift"/>
</RelativeLayout>

activity2.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/img1"
    android:layout_alignParentBottom="true"
    android:transitionName="shift"/>
</RelativeLayout>

Answer 1

You are not setting image for ImageView in your actvity2.xml

Add this in your ImageView of actvity2.xml:

android:background="@drawable/th"
