问题
hi i am making an app where i'm basically i have two activities. In first activity i have one textview and imageview and in imageview i have set a layerlist as background and same goes for the second activity. Now my problem is that when i apply shared element transition animation in first activity then both the textview and imageview are animated but layerlist in second activity losses its shape you can see the below images.
and
Now screens with animation
Now from the above images you easily see the difference when i use animation the image in second screen losses its shape i searched all over the internet but didnt get any proper solution so please if someone can help me out here.
