android - Android Recyclerview same item layout changes after certain number of items

Question

I want to give the possibility to select multible items in a recyclerview. If the users clicks on a item I do following to change the background color of the item:

relativeLayout = viewHolder.rL;
relativeLayout.setBackgroundColor(Color.rgb(224, 224, 224));

this works fine, but after 10 items the item is also grey. If I change setItemViewCacheSize() to for example 100 this problem doesn't occur. But I am not shure if this is the right way.

Recycler view reuses the same views for the different items. So you have to store selection state not only on the UI level.
