How to open new activity in recyclerview with firebase database - java

Im creating a recipe app in android studios with categories(chicken,pork,beef etc) and subcategories.

Add this in your OnBindviewHolder method of Adapter
context = holder.itemView.getContext();
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(context, YourActivity.class);
context.startActivity(i);
}
});

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("Red", R.drawable.android_red));
itemList.add(new Item("Yellow", R.drawable.android_yellow));
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("Red", R.drawable.android_red));
itemList.add(new Item("Yellow", R.drawable.android_yellow));
itemAdapter = new ItemAdapter(itemList, this);
recyclerView.setAdapter(itemAdapter);
}
#Override
public void onItemClicker() {
//????????????????
}
}
Item.java
public class Item {
private String itemName;
private int itemImage;
public Item(String itemName, int itemImage) {
this.itemImage = itemImage;
this.itemName = itemName;
}
public int getItemImage() {
return itemImage;
}
public String getItemName() {
return itemName;
}
public void setItemName(String itemName) {
this.itemName = itemName;
}
}
ItemAdapter.java
public class ItemAdapter extends RecyclerView.Adapter<ItemAdapter.ItemViewHolder> {
private List<Item> itemList;
int row_index = -1;
private ItemAdapterCallback callback;
public ItemAdapter(List<Item> itemList, ItemAdapterCallback callback) {
this.itemList = itemList;
this.callback = callback;
}
public void setFilteredList(List<Item> filteredList) {
this.itemList = filteredList;
notifyDataSetChanged();
}
#NonNull
#Override
public ItemViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.each_item, parent, false );
return new ItemViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull ItemViewHolder holder, int position) {
Item item = itemList.get(position);
holder.itemNameTv.setText(item.getItemName());
holder.itemImageView.setImageResource(item.getItemImage());
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
////////////////////////////
//Toast.makeText(view.getContext(), "Item is clicked" + item.getItemName(), Toast.LENGTH_SHORT).show();
}
});
holder.cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
row_index = position;
notifyDataSetChanged();
Toast.makeText(v.getContext(), "Item is clicked " + position + " " + item.getItemName(), Toast.LENGTH_SHORT).show();
callback.onItemClicker();
}

} else {
return itemList.size();
}
}
public class ItemViewHolder extends RecyclerView.ViewHolder{
public TextView itemNameTv;
public ImageView itemImageView;
public CardView cardView;
public ItemViewHolder(#NonNull View itemView) {
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 to pause ExoPlayer playerView when RecyclerView.SCROLL_STATE_DRAGGING and release player on Destroy

I want to implement a RecyclerView that works similar to Instagram feeds, that contains both Image and Video Items. I have successful implemented the recyclerView to display both image and video items, but I am having issues with pausing the video items when the onScrollListener is on RecyclerView.SCROLL_STATE_DRAGGING I am using ExoPlayer library for the video player"
So, if a video is played and the recyclerView is not pause it keeps on playing that video even if another video is played from the list. Making multiple video playing at the same time.
Below is my implementation Adapter
public class RecyclerAdapter extends RecyclerView.Adapter {
private ArrayList<ListModel> listModelList;
private Context context;
SimpleExoPlayer exoPlayer;
public RecyclerAdapter(ArrayList<ListModel> listModelList, Context context) {
this.listModelList = listModelList;

I have gone through several question here and on youtube, But they all implemeted just a single view type in the recyclerView.
Any suggestion how I could control the Video Player when the recyclerView is been scrolled? Or a better way I could implement the Instagram feeds like RecyclerView

public class NoteAdapter extends FirestoreRecyclerAdapter<Note, NoteAdapter.NoteHolder> {
private Context mContext;
public NoteAdapter(#NonNull FirestoreRecyclerOptions<Note> options) {
super(options);
}
#Override
protected void onBindViewHolder(#NonNull NoteHolder noteHolder, int i, #NonNull Note note) {
noteHolder.title.setText(note.getTitle());
noteHolder.content.setText(note.getContent());
noteHolder.priority.setText(String.valueOf(note.getPriority()));
}
#NonNull
#Override
public NoteHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.note_item,
parent, false);
return new NoteHolder(v);
}
class NoteHolder extends RecyclerView.ViewHolder {
TextView title;
TextView content;
TextView priority;
public NoteHolder(#NonNull View itemView) {
super(itemView);
title = itemView.findViewById(R.id.title_text);
content = itemView.findViewById(R.id.content_text);
priority = itemView.findViewById(R.id.priority_text);
}
}
}

Here the Code u need:
class NoteHolder extends RecyclerView.ViewHolder {
TextView title;
TextView content;
TextView priority;
CardView cardView;
public NoteHolder(#NonNull View itemView) {
super(itemView);
title = itemView.findViewById(R.id.title_text);
content = itemView.findViewById(R.id.content_text);
priority = itemView.findViewById(R.id.priority_text);
cardView = itemView.findViewById(R.id.cardView);
}
private void bind(){
cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(FirstActivity.this, SecoundActivity.class);
startActivity(intent);
}
});
}
}

Fixed it with this code!!!
public NoteHolder(#NonNull final View itemView) {
super(itemView);
cardView = itemView.findViewById(R.id.cardview);
title = itemView.findViewById(R.id.title_text);
content = itemView.findViewById(R.id.content_text);
priority = itemView.findViewById(R.id.priority_text);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
itemView.getContext().startActivity(new Intent(itemView.getContext(),Empty.class));
}
});
}
