I already retrieve the data from FireStore successfully, and i want to search list of data using SearchView, but it doesnt show anything in recyclerView when i try to search in Searchview.
Here is my code for Main Activity. I retrieve the list of data using query and show in recycler View.
public class MainActivity extends AppCompatActivity {
private final static String TAG = MainActivity.class.getSimpleName();
private RecyclerView recyclerView;
private FirebaseAuth mAuth;
private FirebaseFirestore db;
private FoodAdapter mAdapter;
SearchView searchView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAuth = FirebaseAuth.getInstance();
db = FirebaseFirestore.getInstance();
// Force Login
if (mAuth.getCurrentUser() == null || mAuth.getCurrentUser().getEmail().isEmpty()) {
Intent intent = new Intent(this, Login.class);
startActivity(intent);
finish();
}
recyclerView = findViewById(R.id.recycler_home);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView = findViewById(R.id.search);
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setMaxWidth(Integer.MAX_VALUE);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
getSearch(newText);
return false;
}
});
mAdapter = new FoodAdapter(new FoodAdapter.OnFoodClickListener() {
@Override
public void OnClick(FoodModel food) {
Intent intent = new Intent(MainActivity.this, FoodActivity.class);
intent.putExtra("id", food.getId());
startActivity(intent);
}
getFoodData();
recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.VERTICAL, false));
recyclerView.setAdapter(mAdapter);
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
getFoodData();
}
public void getSearch(String s){
mAdapter.clear();
Query que = db.collection("Food");
que.whereEqualTo("title", s);
que
.get()
.addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
@Override
public void onSuccess(QuerySnapshot documentSnapshots) {
if (!documentSnapshots.isEmpty()) {
for (DocumentSnapshot docSnap : documentSnapshots.getDocuments()) {
FoodModel model = docSnap.toObject(FoodModel.class);
model.setId(docSnap.getId());
loadSticker(model);
}
}
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.d(TAG, e.getLocalizedMessage());
}
});
}
public void getFoodData() {
mAdapter.clear();
Query query = db.collection(“Food”);
query
.get()
.addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
@Override
public void onSuccess(QuerySnapshot documentSnapshots) {
if (!documentSnapshots.isEmpty()) {
for (DocumentSnapshot docSnap : documentSnapshots.getDocuments()) {
FoodModel model = docSnap.toObject(FoodModel.class);
model.setId(docSnap.getId());
loadSticker(model);
}
}
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.d(TAG, e.getLocalizedMessage());
}
});
}
public void loadSticker(final FoodModel foodModel) {
db
.collection("beverage")
.whereEqualTo("name", foodModel.getBeverage())
.get()
.addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
@Override
public void onSuccess(QuerySnapshot documentSnapshots) {
if (documentSnapshots.getDocuments().get(0).exists()) {
BeverageModel model = documentSnapshots.getDocuments().get(0).toObject(BeverageModel.class);
FoodModel newFoodModel = foodModel;
newFoodModel.setSticker(model.getSticker());
mAdapter.addItem(newFoodModel);
}
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.d(TAG, e.getLocalizedMessage());
}
});
}
}
Here is the adapter code, which i apply filter for searchView. Anybody knows whats the error in my code for adapter.
public class FoodAdapter extends RecyclerView.Adapter<FoodAdapter.FoodViewHolder> {
private List<FoodModel> foodModels;
private List<FoodModel>foodModelsList;
private OnFoodClickListener listener;
public FoodAdapter(OnFoodClickListener listener) {
foodModels = new ArrayList<>();
this.foodModelsList = foodModels;
this.listener = listener;
}
@Override
public FoodViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.view_holder_food, parent, false);
return new FoodViewHolder(view);
}
@Override
public void onBindViewHolder(FoodViewHolder holder, int position) {
FooModel model = foodModels.get(position);
holder.title.setText(model.getTitle());
holder.description.setText(model.getDescription());
Picasso.get().load(model.getSticker()).into(holder.sticker);
}
@Override
public int getItemCount() {
return foodModels.size();
}
public void addItem(FoodModel food){
foodModels.add(food);
notifyDataSetChanged();
}
class FoodViewHolder extends RecyclerView.ViewHolder {
private TextView name, description;
private ImageView sticker;
FoodViewHolder(View itemView) {
super(itemView);
title = itemView.findViewById(R.id.tv_title);
sticker = itemView.findViewById(R.id.img_sticker);
description = itemView.findViewById(R.id.tv_description);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int position = getAdapterPosition();
listener.OnClick(foodModels.get(position));
}
});
}
}
public interface OnFoodClickListener{
void OnClick(FoodModel food);
}
}
