Page fixed at a specific post in recyclerview
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have an activity A. From that activity I go to activity B. Now there are some image descriptions in A and the corresponding images are in B. I want to make a system where based on the descriptions from activity A, the screen gets fixed to the post with the specific image among all the posts when I move from A to B. In other words I want to fix recyclerview to a specific child when the activity B opens.
P.S.- I have the postkeys of all the posts in recyclerview in B in my database.
Thanks in advance.

What problem are you facing? and what did you do so far?

I actually don't have a clue how to do it. If I only use intent, it will go the first post in the recyclerview in B. I have passed the postkey of the specific post from A to B. Now I want to set the recyclerview to the exact post with the postkey

I'm not if I understood you correctly, when you pass postKey from A to B, get the items from your database related to that passed postKey and set it to your recyclerview. Or do you want any specific row to be focused/Selected?
