When I click on the RecyclerView Item in MainActivity I want the TextView in MainActivity to display Item's title

>>>>>>>MAIN ACTIVITY XML<<<<<<<
As you can see the TextView is on the top, that's where I want to display the title of selected RecyclerView item. Most of the tutorials and blog teach to navigate to next activity when an item is clicked, but that isn't something I am looking for.
MainActivity.java
public class MainActivity extends AppCompatActivity implements ItemAdapterCallback {
private RecyclerView recyclerView;
private List<Item> itemList;
private ItemAdapter itemAdapter;
private SearchView searchView;
TextView itemname;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initialize(savedInstanceState);
initializeLogic();
}
private void initialize(Bundle savedInstanceState) {
recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
searchView = (SearchView) findViewById(R.id.searchView);
searchView.clearFocus();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
filterList(newText);
return true;
}
});
}
private void filterList(String newText) {
List<Item> filteredList = new ArrayList<>();
for (Item item : itemList) {
if (item.getItemName().toLowerCase().contains(newText.toLowerCase())){
filteredList.add(item);
}
}
if (filteredList.isEmpty()) {
Toast.makeText(this, "No Match", Toast.LENGTH_SHORT).show();
} else {
itemAdapter.setFilteredList(filteredList);
}
}
private void initializeLogic() {
RecyclerView();
}
private void RecyclerView () {
itemList = new ArrayList<>();
// Adding Data to Item List
itemList.add(new Item("Black", R.drawable.android_black));
itemList.add(new Item("Blue", R.drawable.android_blue));
itemList.add(new Item("Green", R.drawable.android_green));
itemList.add(new Item("Pink", R.drawable.android_pink));

itemList.add(new Item("Yellow", R.drawable.android_yellow));
itemList.add(new Item("Black", R.drawable.android_black));

itemList.add(new Item("Pink", R.drawable.android_pink));
itemList.add(new Item("Red", R.drawable.android_red));
itemList.add(new Item("Yellow", R.drawable.android_yellow));

super(itemView);
cardView = itemView.findViewById(R.id.eachCardView);
itemNameTv = itemView.findViewById(R.id.eachItemTextView);
itemImageView = itemView.findViewById(R.id.eachItemImageView);
}
}
}
ItemAdapterCallback (Interface)
public interface ItemAdapterCallback {
void onItemClicker();
}

You are just missing few things here.
1- if you want to get the title from the adapter you will need to pass the title in your Callback Interface
public interface ItemAdapterCallback {
void onItemClicker(String title);}
2- after this change you will override the onItemClickerCallback in your mainActivity
it will look like this
#Override
public void onItemClicker(String title) {
// your title ,
itemname.setText(title);
}
3- in onClick function of the adapter add this line
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(callback!=null){
callback.onItemClicker( item.getItemName());
}
}
});
that's all you need to do to show the title in your mainActivity from adapter.

Having problem to fetching file from firestore recycle view [duplicate]

This question already has an answer here:
Firebase Android ListView not being displayed
(1 answer)
Closed 1 year ago.
I am an android developer beginner, I am having a problem fetch files from firestore recycle view in the main activity but I can fetch files from fragments.
This is my main activity
public class FoodInfoActivity extends AppCompatActivity {
RecyclerView recyclerView1,recyclerView2;
private FirebaseFirestore db = FirebaseFirestore.getInstance();
private CollectionReference notebookRef;
private NoteAdapter adapter;
FirebaseAuth fAuth;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_food_info);
fAuth = FirebaseAuth.getInstance();
setUpRecyclerView();
}
private void setUpRecyclerView() {
notebookRef = db.collection("FoodInside");
Query query = notebookRef;
FirestoreRecyclerOptions<FoodAdapter> options = new FirestoreRecyclerOptions.Builder<FoodAdapter>()
.setQuery(query, FoodAdapter.class)
.build();
adapter = new NoteAdapter(options);
RecyclerView recyclerView = findViewById(R.id.fi);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(adapter);
}
}
This is my Note adapter where i use model class to fetch file
public class NoteAdapter extends FirestoreRecyclerAdapter<FoodAdapter, NoteAdapter.NoteHolder> {
public NoteAdapter(#NonNull FirestoreRecyclerOptions<FoodAdapter> options) {
super(options);
}
#Override
protected void onBindViewHolder(#NonNull NoteHolder holder, int position, #NonNull FoodAdapter foodAdapter) {
holder.textViewTitle.setText(foodAdapter.getRestaurant());
holder.textViewDescription.setText(foodAdapter.getItem());
holder.textViewPriority.setText(String.valueOf(foodAdapter.getPrice()));
}
#NonNull
#Override
public NoteHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.food_recycle_layout,
parent, false);
return new NoteHolder(v);
}
class NoteHolder extends RecyclerView.ViewHolder {
TextView textViewTitle;
TextView textViewDescription;
TextView textViewPriority;
public NoteHolder(View itemView) {
super(itemView);
textViewTitle = itemView.findViewById(R.id.textView95a);
textViewDescription = itemView.findViewById(R.id.textView123a);
textViewPriority = itemView.findViewById(R.id.textView124a);
}
}
}
This is my adapter class ,
public class FoodAdapter {
String Restaurant;
String Item;
String Price;
String item_id;
public FoodAdapter() {
}
public FoodAdapter(String restaurant, String item, String price,String item_id) {
Restaurant = restaurant;
Item = item;
Price = price;
this.item_id = item_id;
}
public String getRestaurant() {
return Restaurant;
}
public void setRestaurant(String restaurant) {
Restaurant = restaurant;
}
public String getItem() {
return Item;
}
public void setItem(String item) {
Item = item;
}
public String getPrice() {
return Price;
}
public void setPrice(String price) {
Price = price;
}
public String getItem_id() {
return item_id;
}
public void setItem_id(String item_id) {
this.item_id = item_id;
}
}
Why it is not working in main activity but work fragment. I am just afraid. and tired...working on the project. so need solution of this problem

#Override
protected void onStart() {
super.onStart();
adapter.startListening();
}
#Override
protected void onStop() {
super.onStop();
adapter.stopListening();
}
Add this line to main activity.

How I connect recyclerview to firebase database insert,update and delete data

I create an app which contain recyclerview and I add data in recyclerview arrayList from alertDilog and edit,delete data from AlertDilog according to the user click .It works properly but when I connect my app to firebase Database, my app doesn't work properly.
Recyclerview Adapter:

ArrayList<customitem> datalist;
vonclick mclick;

#Override

return new Viewholder(v,mclick);
}
public recyclerviewadapter(ArrayList<customitem> datalist) {
this.datalist = datalist;
}
#Override
public void onBindViewHolder(#NonNull Viewholder holder, int position) {
customitem n = datalist.get(position);
holder.productname.setText(n.getproductname());
}
#Override
public int getItemCount() {
return datalist.size();
}
public class Viewholder extends RecyclerView.ViewHolder {
TextView productname;
public Viewholder(#NonNull View itemView, final vonclick listener) {
super(itemView);
productname = itemView.findViewById(R.id.titleid);
