I'm creating a simple note app in which I'm showing the content in recycler view from firestore. Something is wrong in the code its not displaying the content in the recylerview(though I'm getting a new item each time I add a new note). Also it not updated as soon as I add a new note, its updated once I destroy the app.
Main activity
public class MainActivity extends AppCompatActivity {
RecyclerView recyclerView;
CustomAdapter customAdapter;
ArrayList<Model> models;
FirebaseFirestore firebaseFirestore;
FloatingActionButton fab;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = findViewById(R.id.recyclerView);
models = new ArrayList<>();
firebaseFirestore = FirebaseFirestore.getInstance();
customAdapter = new CustomAdapter(this, models);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
linearLayoutManager.setReverseLayout(true);
linearLayoutManager.setStackFromEnd(true);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setAdapter(customAdapter);
firebaseFirestore = FirebaseFirestore.getInstance();
firebaseFirestore.collection("my_notes_collection").get()
.addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
#Override
public void onSuccess(QuerySnapshot queryDocumentSnapshots) {
if(!queryDocumentSnapshots.isEmpty()){
List<DocumentSnapshot> list = queryDocumentSnapshots.getDocuments();
for(DocumentSnapshot d : list){
Model model = d.toObject(Model.class);
models.add(model);
}
customAdapter.notifyDataSetChanged();
}
else
Toast.makeText(getApplicationContext(), "No data", Toast.LENGTH_SHORT).show();
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(getApplicationContext(), "Fail to get the data.", Toast.LENGTH_SHORT).show();
}
});
fab = findViewById(R.id.fab);
fab.setOnClickListener(view -> addData());
}
private void addData() {
Intent intent = new Intent(this, DataAdd.class);
startActivity(intent);
}
}
CustomAdapter
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.MyViewHolder>{
Context context;
ArrayList<Model> models;
public CustomAdapter(Context context, ArrayList<Model> models){
this.context = context;
this.models = models;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.list_content, parent, false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
holder.time_text.setText(models.get(holder.getBindingAdapterPosition()).getText());
holder.string_text.setText(models.get(holder.getBindingAdapterPosition()).getNotes());
holder.constraintLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(context.getApplicationContext(), NotesDetails.class);
intent.putExtra("position", String.valueOf(holder.getBindingAdapterPosition()));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
});
}
#Override
public int getItemCount() { return models.size(); }
public class MyViewHolder extends RecyclerView.ViewHolder {
TextView string_text, time_text;
ConstraintLayout constraintLayout;
public MyViewHolder(View itemView) {
super(itemView);
string_text = itemView.findViewById(R.id.textView);
time_text = itemView.findViewById(R.id.timeshow);
constraintLayout = itemView.findViewById(R.id.constraintLayout);
}
}
}
By looks of it, the reason its not updating RV is because we are not asking the code to do that, yet.
So listen for when DataAdd activity has completed its addition task by using startActivityForResult() please see an example here
Then when we know add was successful, we get a callback in, onActivityResult() we then reload list from Firebase
firebaseFirestore.collection("my_notes_collection").get()
...
again such that the list is updated and dataset is notified..

I'm loading some data into a RecyclerView from Firebase Realtime Database. This RecyclerView is in a fragment and I want to open a new activity when an item is clicked. But when i add the onClickListener to an item from the adapter, my click doesn't even recognized by the app. I'm not sure what I'm doing wrong here because this method worked fine for a RecyclerView when it is inside of a normal activity.
This is a project for my university and I should submit it tomorrow. So I can really use some help.
This is the my data Adapter class,
public class Adapter_NoLimit extends RecyclerView.Adapter<Adapter_NoLimit.LViewHolder> {
Context context;
ArrayList<Helper> list_nl;
public Adapter_NoLimit(Context context, ArrayList<Helper> list_nl) {
this.context = context;
this.list_nl = list_nl;
}
#NonNull
#Override
public Adapter_NoLimit.LViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(context).inflate(R.layout.itemlist, parent, false);
return new LViewHolder(v);
}
#Override
public void onBindViewHolder(#NonNull Adapter_NoLimit.LViewHolder holder, int position) {
//final Helper temp = list_nl.get(position);
String fname_txt = list_nl.get(position).getFname();
String catg_txt = list_nl.get(position).getSpin();
String prof_img = list_nl.get(position).getProfile_url();
holder.setUsers(fname_txt, catg_txt, prof_img);
holder.f_name.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
AppCompatActivity activity = (AppCompatActivity) v.getContext();
Intent i = new Intent(activity, UserProfile_VV.class);
i.putExtra("full name", fname_txt);
activity.startActivity(i);
}
});
}
#Override
public int getItemCount() {
return list_nl.size();
}
public class LViewHolder extends RecyclerView.ViewHolder{
private TextView f_name, catG;
private ImageView profile_pic;
public LViewHolder(#NonNull View itemView) {
super(itemView);
f_name = itemView.findViewById(R.id.username_view);
catG = itemView.findViewById(R.id.category_view);
profile_pic = itemView.findViewById(R.id.userimage);
}
public void setUsers(String fname_txt, String catg_txt, String prof_img) {
f_name.setText(fname_txt);
catG.setText(catg_txt);
Picasso.get().load(prof_img).fit().into(profile_pic);
}
}
}
This is one of fragments,
public class Beauty_Frag extends Fragment {
RecyclerView recyclerView;
DatabaseReference reference, user_ref;
ArrayList<Helper> list;
Adapter adapter;
FirebaseAuth auth;
String uid;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_beauty, container, false);
recyclerView = v.findViewById(R.id.beauty_recycler_frag);
reference = FirebaseDatabase.getInstance().getReference();
user_ref = reference.child("users");
auth = FirebaseAuth.getInstance();
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
//searchField = findViewById(R.id.search_field);
list = new ArrayList<>();
adapter = new Adapter(getContext(), list);
recyclerView.setAdapter(adapter);
user_ref.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(#NonNull /*#org.jetbrains.annotations.NotNull*/ DataSnapshot snapshot) {
for (DataSnapshot key : snapshot.getChildren()) {
if( key.child("spin").getValue().toString().equals("Beauty")) {
Helper helper = key.getValue(Helper.class);
list.add(helper);
adapter.notifyDataSetChanged();
}
}
}
#Override
public void onCancelled(#NonNull /*#org.jetbrains.annotations.NotNull*/ DatabaseError error) {
}
});
return v;
}
}
You are very welcome if you have any solution.
Use below code for onClicklistner:
holder.f_name.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(context, UserProfile_VV.class);
i.putExtra("full name", fname_txt);
context.startActivity(i);
}
});
I have created a simple notes app in which I'm storing data in firebase. Showing the list of notes(time and few words of a note) in recyclerview. Now I want when I click in a particular note, it take to different activity where the details of the note will be shown. I am not able to get data from firebase column wise(note and time).
CustomAdapter
Here I'm sending the position of the item clicked to NotesDetails class
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.MyViewHolder> {
Context context;
ArrayList<Model> models;
public CustomAdapter(Context context, ArrayList<Model> models){
this.context = context;
this.models = models;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.list_content, parent, false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
holder.time_text.setText(models.get(holder.getBindingAdapterPosition()).getText());
holder.string_text.setText(models.get(holder.getBindingAdapterPosition()).getNotes());
holder.constraintLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(context.getApplicationContext(), NotesDetails.class);
intent.putExtra("position", String.valueOf(holder.getBindingAdapterPosition()));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
});
}
#Override
public int getItemCount() { return models.size(); }
public class MyViewHolder extends RecyclerView.ViewHolder {
TextView string_text, time_text;
ConstraintLayout constraintLayout;
public MyViewHolder(View itemView) {
super(itemView);
string_text = itemView.findViewById(R.id.textView);
time_text = itemView.findViewById(R.id.timeshow);
constraintLayout = itemView.findViewById(R.id.constraintLayout);
}
}
}
NotesDetails
I want to show time and details of particular item here in testShow and timeShow
public class NotesDetails extends AppCompatActivity {
ArrayList<Model> models;
TextView textShow, timeShow;
DBHelper myDB;
DatabaseReference dbReference;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notes_details);
textShow = findViewById(R.id.notesShow);
timeShow = findViewById(R.id.timeshow);
myDB = new DBHelper(this);
Intent intent = getIntent();
int position = Integer.parseInt(intent.getStringExtra("position"));
dbReference = FirebaseDatabase.getInstance().getReference("Model").child("notes");
dbReference.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(#NonNull #NotNull DataSnapshot snapshot) {
for(DataSnapshot dataSnapshot: snapshot.getChildren()){
Model m1 = dataSnapshot.getValue(Model.class);
textShow.setText((CharSequence) m1);
}
}
#Override
public void onCancelled(#NonNull #NotNull DatabaseError error) {
}
});
}
}
My recyclerview always reset to first position after new data is inserted to firebase. In my TestAdapter class, I have an onClickListener which increments like on a post when clicked. Whenever I click on this "like" button, view is reset to first position. I believe this issue is related to setAdapter() being called on data changed. Please help!
MainActivity fetches "post" data from Firebase and populates it in TestAdapter class.
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private TestAdapter testAdapter;
private ArrayList<Post> postList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
fetchPostFromDB();
}
private void fetchPostFromDB() {
DatabaseReference databaseRef = FirebaseDatabase.getInstance().getReference("Post");
databaseRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot snapshot) {
postList = new ArrayList<>();
for (DataSnapshot snap : snapshot.getChildren()) {
String post = snap.child("post").getValue().toString();
Post post = new Post(post);
postList.add(post);
}
testAdapter = new TestAdapter(getApplicationContext(), postList);
recyclerView.setAdapter(testAdapter);
}
#Override
public void onCancelled(#NonNull DatabaseError error) {
}
});
}
TestAdapter binds the data (postList) and has an onClickListener.
public class TestAdapter extends RecyclerView.Adapter<TestAdapter.TestHolder> {
private List<Post> postList;
private Context context;
private DatabaseReference databaseReference;
public TestAdapter(Context ct, ArrayList<Post> postList) {
context = ct;
this.postList = postList;
}
#NonNull
#Override
public TestHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
LayoutInflater layoutInflater = LayoutInflater.from(context);
View view = layoutInflater.inflate(R.layout.post_item, parent, false);
final TestHolder holder = new TestHolder(view);
holder.ibLike.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String postID = postList.get(holder.getAdapterPosition()).getPostID();
databaseReference = FirebaseDatabase.getInstance().getReference("Posts").child(postID).child("likes");
int incrementLike = postList.get(holder.getAdapterPosition()).getLikes() + 1;
databaseReference.setValue(incrementLike);
}
});
return holder;
}
#Override
public void onBindViewHolder(#NonNull final TestHolder holder, final int position) {
holder.tvPost.setText(postList.get(position).getPost());
holder.tvVotes.setText(Integer.toString(postList.get(position).getLikes()));
}
#Override
public int getItemCount() {
return postList.size();
}
public static class TestHolder extends RecyclerView.ViewHolder {
TextView tvPost, tvLikes;
ImageButton ibLike;
public TestHolder(#NonNull View itemView) {
super(itemView);
tvPost = itemView.findViewById(R.id.tvPost);
tvLikes = itemView.findViewById(R.id.tvLikes);
ibLike = itemView.findViewById(R.id.ibLike);
}
}
Here need to initialize your adapter class from main activity. and then when data received just call adapter.notifiyDatasetChanged like:
onCreate():
postList = new ArrayList<>();
recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
testAdapter = new TestAdapter(getApplicationContext(), postList);
recyclerView.setAdapter(testAdapter);
and from your fetchPostFromDB delete adapter initialization insted of this just put this line testAdapter.notifiyDataSetChanged()
And when click on text button you can update/handle like this:
holder.ibLike.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String postID = postList.get(holder.getAdapterPosition()).getPostID();
databaseReference = FirebaseDatabase.getInstance().getReference("Posts").child(postID).child("likes");
int incrementLike = postList.get(holder.getAdapterPosition()).getLikes() + 1;
postList.get(holder.getAdapterPosition()).setLikes(incrementLike);
databaseReference.setValue(incrementLike);
notifyDataSetChanged();
}
});
I am trying to retrieve some data from Firebase Firestore although I am able to show the data on Logcat window but when I add it into my recycler view it doesn't show , recycler view doesn't inflate. I am unable to figure it out what I am currently missing although code runs without any error.
private FirebaseFirestore db = FirebaseFirestore.getInstance();
private CollectionReference sellerRef;
RecyclerView mRecyclerView;
List<Products> mProducts;
Adapter adapter;
String TAG="MyTag";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRecyclerView = findViewById(R.id.mRecyclerView);
mProducts=new ArrayList<>();
GridLayoutManager gridLayoutManager = new GridLayoutManager(this,2,GridLayoutManager.VERTICAL,false);
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setLayoutManager(gridLayoutManager);
adapter = new Adapter(this,mProducts);
mRecyclerView.setAdapter(adapter);
adapter.notifyDataSetChanged();
sellerRef=db.collection("Sellers");
Query query =sellerRef.whereEqualTo("City_Name","Sydney");
query.get().addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
#Override

for (QueryDocumentSnapshot document : task.getResult()) {
Products products =document.toObject(Products.class);
mProducts.add(products);
Log.d(TAG,""+products.getCity_Name()+" "+mProducts.size());
}
}else {
Toast.makeText(MainActivity.this, "Failed to load Data", Toast.LENGTH_SHORT).show();
}
}
});
}
}

Call adapter.notifyDataSetChanged(); after update data
I'm seeking help on how to load a data stored in a Firebase Database into a recyclerview.
The below screenshot indicates how I would like for the data to be structured when loaded into the recyclerview.
I am able to access the data from individual paths such as "Upcoming/Events/03/23" using the addEventListener but unable to load dynamically into a recyclerview in the format above.
See Code below that I have below to load the children under the different nodes, but i'm able to load it into the recyclerview
private ListView mUserList;
private ArrayList<String> mUpcomingList = new ArrayList<>();
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_expandable_list_item_1,mUpcomingList);
mUserList.setAdapter(arrayAdapter);
String CurrentString = date.toString().trim();
StringTokenizer tokens = new StringTokenizer(CurrentString, "/");
String first = tokens.nextToken();
String second = tokens.nextToken();
mDatabase = FirebaseDatabase.getInstance().getReference().child("Upcoming/Events").child(first);
mDatabase.addValueEventListener(new ValueEventListener() {
#Override
Public void onDataChange(DataSnapshot dataSnapshot) {
Log.d(TAG,"Listing children");
for (DataSnapshot child: dataSnapshot.getChildren()) {
mUpcomingList.add(child.getKey());
arrayAdapter.notifyDataSetChanged();
}
Your help is appreciated.
when you used then you make recyclerview adatper and bind this adapter into a recycler view . used below code for display firebase all the data and change according your need and make changes.
RecyclerView Adapter::
public class DisplayAllData extends RecyclerView.Adapter<DisplayAllData.ItemViewHolder>{
private List<User> mUserLsit=new ArrayList<>();
private Context mContext;
#Override
public ItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.row_layout,parent,false);
return new ItemViewHolder(view);
}
public DisplayAllData(Context mContext,List<User> mUserLsit) {
this.mContext=mContext;
this.mUserLsit = mUserLsit;
}
#Override
public void onBindViewHolder(ItemViewHolder holder, int position) {
User user=mUserLsit.get(position);
holder.mTvName.setText(user.name);
holder.mTvEmail.setText(user.email);
holder.mTvPwd.setText(user.pwd);
}
#Override
public int getItemCount() {
return mUserLsit.size();
}
public class ItemViewHolder extends RecyclerView.ViewHolder {
TextView mTvName,mTvEmail,mTvPwd;
public ItemViewHolder(View itemView) {
super(itemView);
mTvEmail=itemView.findViewById(R.id.rlTvEmail);
mTvName=itemView.findViewById(R.id.rlTvName);
mTvPwd=itemView.findViewById(R.id.rlTvPwd);
}
}
}
In Adapter take a simple layout and make three textview control and bind data into that.
then after take activity layout and define recycler view in xml. then after used below code to read firebase database record and display recyclerview.
public class DisplayActivity extends AppCompatActivity {
private RecyclerView mRvData;
private DisplayAllData allDataAdapter;
private DatabaseReference mDatabase;
private TextView mTvEmpty;
private FirebaseDatabase mFirebaseInstance;
private List<User> mUserList = new ArrayList<>();
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.display_data);
initView();
}
private void initView() {
mFirebaseInstance = FirebaseDatabase.getInstance();
mDatabase = mFirebaseInstance.getReference("usersDb/UserTable");
mRvData = findViewById(R.id.rvData);
mTvEmpty = findViewById(R.id.dlTvEmpty);
mRvData.setLayoutManager(new LinearLayoutManager(this));
mDatabase.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
mUserList.clear();
for (DataSnapshot dataSnapshot1 : dataSnapshot.getChildren()) {
User user = dataSnapshot1.getValue(User.class);
mUserList.add(user);
}
allDataAdapter = new DisplayAllData(DisplayActivity.this, mUserList);
mRvData.setAdapter(allDataAdapter);
allDataAdapter.notifyDataSetChanged();
if (mUserList.isEmpty())
mTvEmpty.setVisibility(View.VISIBLE);
else
mTvEmpty.setVisibility(View.GONE);
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
}
You have to use FirebaseRecyclerAdapter,
as
FirebaseRecyclerAdapter<Model, ViewHolder> Adapter = new FirebaseRecyclerAdapter<Model, ViewHolder>(
Model.class, //Name of model class
R.layout.row, //Row layout to show data
viewHolder.class, //Name of viewholder class
mDatabaseRef // Database Refernce
) {
#Override
protected void populateViewHolder(VieHolder viewHolder, Model model, int position) {
//Your Method to load Data
}
};
RecyclerView.setAdapter(Adapter);
For this you have to create two other classes, One is viewholder ( to display data) and second model class ( refers to name of nodes from where you are fetching data ).
final DatabaseReference cartListRef = FirebaseDatabase.getInstance().getReference().child("Cart List");
FirebaseRecyclerOptions<Cart> options = new FirebaseRecyclerOptions.Builder<Cart>()
.setQuery(cartListRef.child("User View")
.child(Prevalent.currentOnlineUser.getPhoneNumber())
.child("Products"), Cart.class).build();
FirebaseRecyclerAdapter<Cart, CartViewHolder> adapter =
new FirebaseRecyclerAdapter<Cart, CartViewHolder>(options) {
#Override
protected void onBindViewHolder(#NonNull CartViewHolder holder, int position, #NonNull final Cart model) {
holder.txtProductQuantity.setText("Quantity = " + model.getQuantity());
holder.txtProductName.setText(model.getPname());
holder.txtProductPrice.setText("Price = " + model.getPrice() + "৳");
int oneTypeProductPrice = ((Integer.valueOf(model.getPrice()))) * Integer.valueOf(model.getQuantity());
overTotalPrices = overTotalPrices + oneTypeProductPrice;
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
CharSequence options[] = new CharSequence[]
{
"Edit",
"Remove"
};
AlertDialog.Builder builder = new AlertDialog.Builder(CartActivity.this);
builder.setTitle("Cart Options");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int i) {
if (i == 0){
Intent intent = new Intent(CartActivity.this, ProductDetailsActivity.class);
intent.putExtra("pid", model.getPid());
startActivity(intent);
}
if (i == 1){
cartListRef.child("User View")
.child(Prevalent.currentOnlineUser.getPhoneNumber())
.child("Products")
.child(model.getPid())
.removeValue()
.addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if (task.isSuccessful()){
Toast.makeText(CartActivity.this,"Item removed successfully.",Toast.LENGTH_LONG).show();
Intent intent = new Intent(CartActivity.this, HomeActivity.class);
startActivity(intent);
}
}
});
}
}
});
builder.show();
}
});
}
#NonNull
#Override
public CartViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.cart_items_layout, parent, false);
CartViewHolder holder = new CartViewHolder(view);
return holder;

recyclerView.setAdapter(adapter);
adapter.startListening();
