如何根据本地或数据库中的字段值更改更新 Firestore RecyclerView 适配器？

Question

I'm trying to reload or update Firestore Recyclerview Adapter (Firebase Ui) based upon field value changes.

In my case I'm querying .whereNotIn("id", list) where list is stored locally and updated frequently which should trigger firestore recyclerview options based upon arraylist value updated.

My code is below:

 postsRef
                .orderBy("id")
                .whereNotIn("id", list) // list is updated frequently so update firesttore recyclervew option
                .whereEqualTo("disabled", false)
                .whereEqualTo("expired", false)
                .whereEqualTo("locality", locality)
                .whereEqualTo("country", country)
                .orderBy("createdAt", Query.Direction.DESCENDING)
                .limit(20)

        val firestoreRecyclerOptions: FirestoreRecyclerOptions<Post> =
            FirestoreRecyclerOptions.Builder<Post>()
                .setQuery(query, Post::class.java)
                .build()

"list" value is changes locally frequently. I want to update firestore RecyclerView options maybe reload based upon list update.

The list is updated as the data in the table is updated.

The code I wrote for myself, you can change it according to you.

docRef
                    .whereEqualTo(field, equel)
                    .whereEqualTo(cevapField, cevapdurum)
                    .orderBy("date",query)
                    .addSnapshotListener { querySnapshot, firebaseFirestoreException ->
                        firebaseFirestoreException?.let {
                            Toast.makeText(context, it.message, Toast.LENGTH_LONG)
                                .show()
                           //error
                            return@addSnapshotListener
                        }
                        val listData: MutableList<Any> = mutableListOf()
                        querySnapshot?.let {
                            for (document in it) {
                               //success
                                val data1=document.getString("data1")
                        }
                    }
