Develop Reference

Whenever I add new Data to FireStore DataBase and display it to recyclerView , it only shows the newly added data. Here is my Code :

The recycler view only shows the recent add i.e the single element which is newly added, and the rest of the activity is blank, Also whenever I switch fragments and visit again the main fragment it shows all data?
Place to display data and set Adapter:
public class HomeFragment extends Fragment {
private RecyclerView recyclerView;
private List<BlogPost> blogList;
private FirebaseFirestore firestore;
private FirebaseDatabase database;
private DatabaseReference reference;
private BlogPostAdapter adapter;
public HomeFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_home, container, false);
blogList = new ArrayList<>();
firestore = FirebaseFirestore.getInstance();
recyclerView = (RecyclerView)view.findViewById(R.id.post_list_view);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(view.getContext()));
EventChangeListener();
adapter = new BlogPostAdapter(blogList);
recyclerView.setAdapter(adapter);
return view;
}
public void EventChangeListener() {
Query firstQuery = firestore.collection("Posts").orderBy("TimeStamp",Query.Direction.ASCENDING);
firstQuery.addSnapshotListener(new EventListener<QuerySnapshot>() {
#SuppressLint("NotifyDataSetChanged")
#Override
public void onEvent(#Nullable QuerySnapshot value, #Nullable FirebaseFirestoreException error) {
if(error!=null)
{
Log.e("Firestore Error",error.getMessage());
return;
}
blogList.clear();
for(DocumentChange doc : value.getDocumentChanges())
{
if(doc.getType()== DocumentChange.Type.ADDED)
{
String blogPostId = doc.getDocument().getId();
QueryDocumentSnapshot post = doc.getDocument();
BlogPost blogPost = new BlogPost();
Map<String, Object> s = post.getData();
int[] likeCnt = {0};
blogPost.setPost_txt((String) s.get("Post_Content"));
DocumentSnapshot.ServerTimestampBehavior behavior = ESTIMATE;
blogPost.setTimestamp(post.getDate("TimeStamp", behavior));

blogList.add(0,blogPost.withId(blogPostId));
}

adapter.notifyDataSetChanged();

I use a NewPostActivity to post the data in firebase Firestore by creating a collections and retrieving the data in recycler view format as usual, but whenever I retrieve data from firebase and add it to arraylist and display in recyclerView it only shows the newly added element at first and then when I switch to another fragment and come back to homeFragment it shows all the post neatly. I tried finding solutions on youtube but couldn't find any.

Populate details activity with Firebase Real Time Database after click on RecyclerView

i want to click in my recyclerview and open a new activity to show the datails. Ultil now i

and the xml for details

when you are getting data from firebase you saving that data in a Object and then add that object to list, so your list contains objects , so you can pass through the intents same way as you are doing others.
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent=new Intent(v.getContext(),detailactivity.class);
intent.putExtra("keyint", vacaslist.getInterno());

intent.putExtra("madre", vacaslist.getMadre());
intent.putExtra("padre", vacaslist.getPadre());
v.getContext().startActivity(intent);
}
});

you are reading it from the wrong node, you are passing reference that you want to read data from the node Named "users".
Your Database reference should look like this
databaseUser = FirebaseDatabase.getInstance().getReference("Nota").child("Toko_Kita20082020371").child(username_key_new);
Also make sure your list should have all the variables that a node has.
For example a node has
name,id,price,description;
then same varibles should be declared in your list to successfully ready dta from the firebase.

ListView Duplicating Data

Have an android application that on one of the pages has a ListView. The ListView has an array with 5 objects in it that is passed into the list adapter to be displayed. On the list view it shows 5 items but the bottom one is shown as a duplicate. However when you click this item it will show the right data that isn't duplicated on another page. Below see the code and screenshots.
MyJobsFragment.java
private void bidOnList() throws ParseException
{
final ArrayList<String> jobsListArray = new ArrayList<>();
// Iterate through entire bids table
for (DataSnapshot ds : getBidListChildren())
{
// Iterate through the actual bids information
Iterable<DataSnapshot> bidsSnapShot = ds.getChildren();
for (DataSnapshot ds1 : bidsSnapShot)
{
// if the User Id equals the current user added to a list
if (getBidInformation(ds1).getUserID().equals(auth.getCurrentUser().getUid()))
{
boolean active = ds1.child("active").getValue(boolean.class);
if (active)
{
jobsListArray.add(ds.getKey());
}
}
}
}
// Go through the jobs table
for (DataSnapshot ds3 : getJobListChildren())
{
/*
If the job is in the jobsListArray previously and the status is Pending
Add to the jobsList
*/
if (jobsListArray.contains(ds3.getKey()) && getJobInformation(ds3).getJobStatus().equals("Pending"))
{
Date sdf = new SimpleDateFormat("dd/MM/yyyy").parse(genericMethods.getJobInformation(ds3).getCollectionDate());
if (new Date().before(sdf))
{
jobListKey.add(ds3.getKey());
jobList.add(getJobInformation(ds3));
}
}
}
// Display information in ListView
mAdapterBidOn = new MyCustomAdapterForTabViews(getActivity(), isAdded(), host, getLayoutInflater(), getFragmentManager());
mAdapterBidOn.addKeyArray(jobListKey);
mAdapterBidOn.addArray(jobList);
jobListViewBidOn.setAdapter(mAdapterBidOn);
// Press on the object and go view all the Job Information and Bids
jobListViewBidOn.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
BidOnJobsFragment bidOnJobsFragment = new BidOnJobsFragment();
Bundle bundle = new Bundle();
bundle.putSerializable("Job", mAdapterBidOn.mData.get(position));
bundle.putSerializable("JobId", mAdapterBidOn.mDataKeys.get(position));
bidOnJobsFragment.setArguments(bundle);
getFragmentManager().beginTransaction().replace(R.id.content, bidOnJobsFragment).addToBackStack("tag").commit();
}
});
}
The above method adds all the relevant data into an array list and adds it into the adapter.

More code can be provided if needed.
EDIT
Code runs as intended until it hits the 4th element in the array, once that point is hit, it goes off into base java classes that I'm guessing are for the adapter. It is as if its ignoring the last two and recycling the views.

#Override
public long getItemId(int position)
{
return 0;
}
i think problem is in your above adapter method. change this to below :
#Override
public long getItemId(int position)
{
return position;
}

Error in recyclerView

Can anyone check if there are errors in it. here my code, If there is any error in the code please tell me? I don't know how to fix the code Search.java.
in my RecyclerItemClickListener.java
public interface RecyclerItemClickListener {
void onItemClick(int position);
}
My Adapter HierAdapter.java
public class HireAdapter extends RecyclerView.Adapter<HireAdapter.ViewHolder>{

Here Search.java, I wrote notes at each error. Because I did not know how to correct some codes to work with HireAdapter and RecyclerItemClickListener, can anyone solve the error?

Here you are setting onClickListner on the same view twice. The Listener set in the onBindViewHolder will override the Listner set in the onCreateViewHolder method.
