Android Studio не может найти параметр ⇐ Android

У меня есть приложение для Android, которое использует Firebase, и у меня возникает ошибка с запросом. Из моего файла класса: < /p>

public class SearchFragment extends Fragment {

private static final String TAG = "SearchFragment";
private static final int NUM_GRID_COLUMNS = 3;
private static final int GRID_ITEM_MARGIN = 5;

//widgets
private ImageView mSearchButton;
private EditText mTitleET;
private FrameLayout mFrameLayout;

//vars
private String mElasticSearchPassword;
private String mPrefCity;
private String mPrefStateProv;
private String mPrefCountry;
private ArrayList mPosts;
private RecyclerView mRecyclerView;
private PostListAdapter mAdapter;
private String queryText;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
//View view = inflater.inflate(R.layout.fragment_search, container, false);
View view = inflater.inflate(R.layout.fragment_search2, container, false);
//mFilters = (ImageView) view.findViewById(R.id.ic_search);
mSearchButton = (ImageView) view.findViewById(R.id.search_button);
mTitleET = (EditText) view.findViewById(R.id.input_title);
//mSearchText = (EditText) view.findViewById(R.id.input_search);
mRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
mFrameLayout = (FrameLayout) view.findViewById(R.id.container);

return view;
}

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
final DatabaseReference reference = FirebaseDatabase.getInstance().getReference();

mSearchButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {

Query query = reference.child("posts/").orderByChild("title").equalTo(mTitleET.getText().toString().trim()).
query.addListenerForSingleValueEvent(new ValueEventListener()
{
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
if (dataSnapshot.exists()) {
// dataSnapshot is the "issue" node with all children with id 0
for (DataSnapshot ds : dataSnapshot.getChildren()) {
// do something with the individual "issues"
Log.i("TAG", ds.getValue().toString());
}
}
}

@Override
public void onCancelled(DatabaseError databaseError) {
Log.i("ERRRRRROORRR", databaseError.getMessage() + ", so....let´s take a coffee");

}
});

}
});
}

private void setupPostsList(){
RecyclerViewMargin itemDecorator = new RecyclerViewMargin(GRID_ITEM_MARGIN, NUM_GRID_COLUMNS);
mRecyclerView.addItemDecoration(itemDecorator);
GridLayoutManager gridLayoutManager = new GridLayoutManager(getActivity(), NUM_GRID_COLUMNS);
mRecyclerView.setLayoutManager(gridLayoutManager);
mAdapter = new PostListAdapter(getActivity(), mPosts);
mRecyclerView.setAdapter(mAdapter);
}

}

Это специально следующая строка (ы), которая, по -видимому, является проблемой (см. Прикрепленное PIC):
