Edit:
In my Recyclerview the itemViews can expand and collapse.
The expandView is a layout which gets inserted under the clickedItemPosition. Everything works fine, but in following to the Google Material Design Guide-Lines the expanded items should have an shadow under and above the expanded Item. As example Google's Dialer Calllog.
How can I achieve an shadow affect above and below the clicked item?
Already tried to handle the shadow in the items above and below with animating the alpha value but therefore i need to notifyItemChanged() which doesnt really look great.
Any suggestions? Greetings
