I don't really understand the structure of the views you're using.
But, anyway, the idea behind a "RecyclerView" is that it recycles and
reuses the views that are part of the list. It uses a "limited" pool of
inflated views, and "binds" them to the data that's needed on the screen.
So, if you click a star, and change the image to "filled", when that view
is reused, it will still be "filled". You need to choose the image on
the onBindViewHolder,
not only on the onClick for the star.

PS: If you use "Search_Result_Adapter extends RecyclerView.Adapter<
ChildViewHolder>" you can save yourself all the casts to ChildViewHolder on
the whole adapter.
