btnSearch = (Button) findViewById(R.id.btn);
usersList = new ArrayList();
adapterRe = new CustomAdapter(getApplicationContext(), usersList);
mMainList = (RecyclerView) findViewById(R.id.recyvle);
// mMainList.setHasFixedSize(true);
// mMainList.setLayoutManager(new LinearLayoutManager(this));
// mMainList.setAdapter(adapterRe);
btnSearch.setOnClickListener(new View.OnClickListener() {
@Override

}
});
}
private void SearchUserFirebase() {
name = editText.getText().toString();
if(!name.isEmpty()){
Query query = mFirestore.collection("Movies").orderBy("name" ).startAt(name).endAt(name + "\uf8ff");
query.addSnapshotListener(new EventListener() {
@Override
public void onEvent(QuerySnapshot documentSnapshots, FirebaseFirestoreException e) {
if (e != null){
Log.d("TAG", "Error : " + e.getMessage());
}
ArrayList adsList = new ArrayList();
for(DocumentChange doc : documentSnapshots.getDocumentChanges()){
if (doc.getType() == DocumentChange.Type.ADDED){
Movies users = doc.getDocument().toObject(Movies.class);
usersList.add(users);
adapterRe.notifyDataSetChanged();
}
}
Log.d("TAG", "no of records of the search is " + adsList.size());
}
});
}
}
}
This is error
Alex Mamo :
Typically this error appears when you are trying to set the adapter from a background thread and not from the "main" thread (for example inside the onCreate() method).
If you are trying to set the adapter from a "delayed" method like inside the onEvent() method, this warning will always appear.
To solve this, move the creation of the adapter in the same thread and get the following line of code out of that for loop.
adapterRe.notifyDataSetChanged();
