Alright, I've found that issue too. The way I fixed it, is by adding mAdapter.notifyDataSetChanged(); in the FindUsersActivity file.

The code should look something like this: mSearch.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { //Before searching in database, it requires to clear the data. clear(); mAdapter.notifyDataSetChanged(); //Searching for user by email listenForData(); } });
