I have an Android app that uses Firebase and I am having an error with a query.
In my class file I am defining the search and I am getting:
error: cannot find symbol variable query
Here is the code from my class file:
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<Post> 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);
}
}
It is specifically the following line(s) that appear to be the problem (see attached pic):
What is causing this error and what is the solution for this error?
