}

I am fetching data from firestore database and i am having one property called imageurl where the folder name for the image is stored now i want to download url of the particular image by using the folder name from firebase storage.After downloading imageurl i want to populate all data's in recyclerview.Here the issue is before fetching data the adapter is executing i want to execute the adapter after fetching all details.

Are you sure you are using setAdapter only in onPostExecte?

I am sure you don't need an AsyncTask to achieve this: addOnCompleteListener and addOnSuccessListener tells me that they run asynchronously already.

why don't you try this

if(Yourasyctask.isFinshing){

set your recycler view code here also 

}

Note-: set your layout manager before setting adapter

like this

  RecyclerView rv_following_me = (RecyclerView) view.findViewById(R.id.rv_following);

        LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());

        rv_following_me.setLayoutManager(linearLayoutManager);



        followingAdapter = new FollowingAdapter(getActivity(), alMeModel);

        rv_following_me.setAdapter(followingAdapter);

Thanks

why don't you try this

if(Yourasyctask.isFinshing){

set your recycler view code here also 

}

Note-: set your layout manager before setting adapter

like this

  RecyclerView rv_following_me = (RecyclerView) view.findViewById(R.id.rv_following);

        LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());

        rv_following_me.setLayoutManager(linearLayoutManager);



        followingAdapter = new FollowingAdapter(getActivity(), alMeModel);

        rv_following_me.setAdapter(followingAdapter);

Thanks
