I understand this might be a duplicate, but every other solution here didn't work in my case, such as changing the layout_height to wrap_content instead of match_parent.
My Firestore database has 2 values stored inside an array, and I want to display both of them (more in the future) in my RecyclerView, however, it only displays the first value, at position 0.
Here is my Activity where the Recycler and the Adapter are created:
ActivityOs
private FirestoreAdapter listAdapter;
private FirebaseFirestore db = FirebaseFirestore.getInstance();
private CollectionReference osRef = db.collection("cliente");
private DocumentReference docRef = osRef.document("clienteTeste");
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_os);
RecyclerView recyclerView = findViewById(R.id.recyclerViewOs);
/*docRef.get().addOnCompleteListener(task -> {
if (task.isSuccessful()) {
DocumentSnapshot document = task.getResult();
if (document.exists()) {
Log.e("RESULTADO","result:" + document.toString());
}
}
});*/
Query query = osRef.orderBy("serviceOrder",
Query.Direction.ASCENDING);
FirestoreRecyclerOptions<ServiceDocument> options =
new FirestoreRecyclerOptions.Builder<ServiceDocument>()
.setQuery(osRef, ServiceDocument.class)
.build();
listAdapter = new FirestoreAdapter(options);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(listAdapter);
listAdapter.notifyDataSetChanged();
}
#Override
protected void onStart() {
super.onStart();
listAdapter.startListening();
}
#Override
protected void onStop() {
super.onStop();
listAdapter.stopListening();
}
The commented code shows me that the database does indeed return the 2 values stored in it.
Here is my Adapter class:
public class FirestoreAdapter extends FirestoreRecyclerAdapter<ServiceDocument, FirestoreAdapter.ViewHolder> {
public FirestoreAdapter(#NonNull FirestoreRecyclerOptions<ServiceDocument> options) {
super(options);
}
#Override
protected void onBindViewHolder(#NonNull ViewHolder holder, int position, #NonNull ServiceDocument model) {
holder.osIdItem.setText(String.valueOf(model.serviceOrderArray.get(position).getId()));
holder.osClientItem.setText(model.serviceOrderArray.get(position).getClient().getName());
holder.osDateItem.setText(model.serviceOrderArray.get(position).getDate());
holder.osValueItem.setText(String.valueOf(model.serviceOrderArray.get(position).getTotalValue()));
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
View view = layoutInflater.inflate(R.layout.layout_os_item, parent, false);
return new FirestoreAdapter.ViewHolder(view);
}
public class ViewHolder extends RecyclerView.ViewHolder {
private TextView osIdItem;
private TextView osClientItem;
private TextView osDateItem;
private TextView osValueItem;
public ViewHolder(View itemView) {
super(itemView);
osIdItem = itemView.findViewById(R.id.osIDItem);
osClientItem = itemView.findViewById(R.id.osClientNameItem);
osDateItem = itemView.findViewById(R.id.osDateItem);
osValueItem = itemView.findViewById(R.id.osValueItem);
}
}
}
And here are my layouts, activity_os.xml where my RecyclerView is created, and layout_os_item.xml where the layouts for each item of the recycler are made.

Current Result:
Expected Result
Basically, Item 0 or the first item is correct, however, the second item in my database should also appear in Item 1.
I have set up a RecyclerView adapter with ViewPager in an activity namely TvShowEpisodeDetails , it works well but there is one issue, the Layout of RecyclerView is fixed while scrolling up and down in the Fragment(TvShowEpisodeDetailsFragment). But I want it to scroll with them.
The RecyclerView and ViewPager are both set inside viewpager_with_toolbar_overlay.xml Layout , and both has been settup in The Activity.
TvShowEpisodeDetailsFragment is the fragment class which belongs to activity class TvShowEpisodeDetails , the fragment creates as many episodes as a TV Show season can offer.
And off course this issue will be gone if I set RecyclerView adapter inside fragment, but I will get non-fixable highlighting and scrolling issues , that is why I set it inside the activity because it does not give those issues.
I need to make it work somehow inside the activity.
My goal is that RecyclerView and ViewPager has to be in the same layout XML file and they both must either be in the activity or fragment class
Is it possible to make the RecyclerView scroll with rest of the fragment layouts?
or
Is it possible to do it programmatically?
Here is the activity
public class TvShowEpisodeDetails extends MizActivity{
#Override
protected int getLayoutResource() {
return R.layout.viewpager_with_toolbar_overlay;
}
#Override
public void onCreate(Bundle savedInstanceState) {
mBus = MizuuApplication.getBus();
super.onCreate(savedInstanceState);
// Set theme
setTheme(R.style.Mizuu_Theme_NoBackground);
// setting episodeslist
final ArrayList<PlanetModel> episodeslist = new ArrayList<>();
for(TvShowEpisode e : mEpisodes){
episodeslist.add(new PlanetModel(e.mEpisode));
}
// setting RecyclerView
mEpisodesList = (RecyclerView) findViewById(R.id.episodesLIST);
// Setting LinearLayoutManager
LinearLayoutManager layoutManager
= new LinearLayoutManager(this.getApplicationContext(), LinearLayoutManager.HORIZONTAL, false);
//mEpisodesList.setLayoutManager(new LinearLayoutManager(mContext));
mEpisodesList.setLayoutManager(layoutManager);
// Setting RecyclerView Adapter
PlanetAdapter.OnItemClickListener indicatorCallback = new PlanetAdapter.OnItemClickListener() {
#Override
public void onItemClick(String item) {
SharedPreferences getPref = getContext().getSharedPreferences("PlanetAdapter", Context.MODE_PRIVATE);
int pos = getPref.getInt("newPosition", 0);
mViewPager.setCurrentItem(pos,false);
}
};
final PlanetAdapter planetAdapter = new PlanetAdapter(episodeslist,indicatorCallback);
mEpisodesList.setAdapter(planetAdapter);
// Setting ViewPager
mViewPager = (ViewPager) findViewById(R.id.awesomepager);
mViewPager.setAdapter(new TvShowEpisodeDetailsAdapter(getSupportFragmentManager()));
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
planetAdapter.setSelectedIndex(position);
planetAdapter.notifyDataSetChanged();
mEpisodesList.smoothScrollToPosition(position);
//mEpisodesList.scrollToPosition(position);
for (int i=0; i<episodeslist.size(); i++)
{
episodeslist.get(i).setPlanetSelected(false);
}
episodeslist.get(position).setPlanetSelected(true);
ViewUtils.updateToolbarBackground(TvShowEpisodeDetails.this, mToolbar, 0, mEpisodes.get(position).getTitle(), Color.TRANSPARENT);
}
});
if (savedInstanceState != null) {
mViewPager.setCurrentItem(savedInstanceState.getInt("tab", 0));
} else {
for (int i = 0; i < mEpisodes.size(); i++) {
if (mEpisodes.get(i).getSeason().equals(MizLib.addIndexZero(mSeason)) && mEpisodes.get(i).getEpisode().equals(MizLib.addIndexZero(mEpisode))) {
mViewPager.setCurrentItem(i);
break;

I have set up a RecyclerView adapter with ViewPager in an activity namely TvShowEpisodeDetails , it works well but there is one issue, the Layout of RecyclerView is fixed while scrolling up and down in the Fragment(TvShowEpisodeDetailsFragment). But I want it to scroll with them.
It's hard to use the RecyclerView outside of the ViewPager page fragment; because you can't synchronize and link the touch/motion events when you scroll the page up/down (or when you swipe to next/previous page) between both the page fragment and a standalone (i.e. activity) RecyclerView. Even that won't be smooth.
So, the RecyclerView should be a part of the ViewPager page.
And off course this issue will be gone if I set RecyclerView adapter inside fragment, but I will get unfixable highlighting and scrolling issues
So, now the issue of adding the RecyclerView in the ViewPager fragment is the highlighting issue of the RecyclerView item when you click on any item or when you swipe the ViewPager to right/left page.
But, the main issue is that there is a RecyclerView instance per page, i.e. if you have 5 pages, then you have 5 RecyclerViews.
So, it's a cumbersome to track highlighting only within the RecyclerView adapter class. And hence manipulating that with OnClickListeners solely will have issues of linking these RecyclerView and adapter instances together to update their highlighting item.
So, a simpler approach is to pass a parameter to the RecyclerView adapter with the selected item (which is definitely equals to the current ViewPager page position).
And then do a check in the onBindViewHolder() if the position equals to the passed-in value, then highlight the item; otherwise keep items with the original color.
So, wrapping this up into actions:
Change the adapter constructor to accept a highlighted_position parameter
public PlanetAdapter(ArrayList<PlanetModel> episodeslist,
int highlightedPosition, OnItemClickListener listener)
Whenever you create the ViewPager fragment using newInstance() pass-in the current position of the page fragment:
So, in the TvShowEpisodeDetails activity:
for (int i = 0; i < mEpisodes.size(); i++)
fragments.add(TvShowEpisodeDetailsFragment
.newInstance(mShowId,
Integer.parseInt(mEpisodes.get(i).getSeason()),
Integer.parseInt(mEpisodes.get(i).getEpisode()),
i)); // The position
And in the TvShowEpisodeDetailsFragment fragment, register this into a field in the fragment argument:
public static TvShowEpisodeDetailsFragment newInstance(String showId, int season, int episode, int position) { // adding position
TvShowEpisodeDetailsFragment pageFragment = new TvShowEpisodeDetailsFragment();
Bundle bundle = new Bundle();
// trimmed code.
bundle.putInt("position", position); // <<<< into the bundle
pageFragment.setArguments(bundle);
return pageFragment;
}
And set that in the adapter creation:
int currentPosition = getArguments().getInt("position");
planetAdapter = new PlanetAdapter(episodeslist, currentPosition, new PlanetAdapter.OnItemClickListener() {
#Override
public void onItemClick(final int pos) {
mCallback.sendText(pos);
}
});
And reflect that in the adapter to highlight the item:
public class PlanetAdapter extends RecyclerView.Adapter<PlanetAdapter.PlanetViewHolder> {
private final int highlightedPos;
public PlanetAdapter(ArrayList<PlanetModel> episodeslist, int highlightedPosition, OnItemClickListener listener) {
this.episodeslist = episodeslist;
this.listener = listener;
this.highlightedPos = highlightedPosition; // <<< set the position
}
#Override
public void onBindViewHolder(PlanetAdapter.PlanetViewHolder vh, final int position) {
TextView tv = (TextView) vh.itemView;
PlanetModel planetModel = episodeslist.get(position);
tv.setText(planetModel.getPlanetName());
tv.setCompoundDrawablesWithIntrinsicBounds(R.drawable.bg, 0, 0, 0);
if (highlightedPos == position) { //<<<<< Highlight the item
vh.itemView.setBackgroundColor(getContext().getResources().getColor(R.color.colorPrimaryLight));
Log.d("LOG_TAG", "onClick: Highlight item: " + highlightedPos);
} else {
vh.itemView.setBackgroundColor(getContext().getResources().getColor(R.color.colorPrimaryDark));
Log.d("LOG_TAG", "onClick: No highlight: " + highlightedPos);
}
}
}
I am using Recycleview Adapter to show my list of items from Firebase Real-time Database.
I have a button which shows text value from Firebase initially when clicked will change the same key value in Firebase Database and I want it to show the updated text in Button too.
But it doesn't unless exit activity and reopen activity. Then it displays the updated value in Button text instead of the initial one.
How to update and show the value without exiting the Adapter?
I used notifyItemChanged(position) but it doesn't do anything.
Here is my Code
public class SubjectBooksAdapter extends RecyclerView.Adapter<SubjectBooksAdapter.MyViewHolder> {
ArrayList<Books> bookslist;
CardView cv;
FirebaseAuth fauth;
FirebaseDatabase database;
DatabaseReference dbreference;
Books g;
SubjectBooksAdapter adapter;
public SubjectBooksAdapter(ArrayList<Books> bookslist){
this.bookslist = bookslist;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout,parent,false);
return new MyViewHolder(v);
}
public class MyViewHolder extends RecyclerView.ViewHolder {
Button mSolved;
MyViewHolder(final View itemView) {
super(itemView);
database = FirebaseDatabase.getInstance();
dbreference = database.getReference("books");
dbreference.keepSynced(true);
mSolved = (Button) itemView.findViewById(R.id.book_solved);
}
}
#Override
public void onBindViewHolder(final MyViewHolder holder, final int position) {
database = FirebaseDatabase.getInstance();
dbreference = database.getReference("books");
g = bookslist.get(position);
holder.mSolved.setText(g.getMarkid());
holder.bookName.setText(g.getBname());
holder.bookprice.setText("Rs. "+g.getPrice());
holder.sellername.setText(g.getSellername());
holder.mSolved.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
DatabaseReference classicalMechanicsRef = rootRef.child("books").child(g.getCondition()).child(g.getBookid());
ValueEventListener valueEventListener = new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
dataSnapshot.child("bmark").getRef().setValue("Solved");
}
#Override
public void onCancelled(#NonNull DatabaseError databaseError) {
}
};
classicalMechanicsRef.addListenerForSingleValueEvent(valueEventListener);
notifyItemChanged(position);
}
});
#Override
public int getItemCount() {
return bookslist.size();
}
}

Thanks in advance.
Whatever the value you want to change in your adapter you can do using notifyItemChanged(position). NotifyItemChange only works when there is a change in your Model Class.
Let say here you are setting the value your Book Name on a TextView by using this code.
Books g = bookslist.get(position);
holder.bookName.setText(g.getBname());
Now if you want to change the value of Book name on Button click you have to change the value in your ArrayList Model also then notify it.
Books g = bookslist.get(position);
g.setBname("your new value");
After this, your notifyItemChanged(position) will display the new value. This is how notify works in RecyclerView
Why you have to do so?
Whenever the notify is called in RecylerView it again set the value from the ArrayList. But in your case, the value is not updated locally in your list but is updated in the FireBase. That's why you get the updated value whenever you again open your app.
NOTE
To change the value of Button with text Remove, get the Markid in the Datachange of the FireBase. Then set that value in the respective model(of that position) from the ArrayList for String Markid.
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
dataSnapshot.child("bmark").getRef().setValue("Solved");
// Here you need to save the value in the arraylist.
bookslist.get(position).setMardid("Here what ever the value you will pass will get updated on the button after notify"); //Try adding the static string that you want after button click.
notifyItemChanged(position)
}
I am making a app in which a activity shows some blog post data in card view. Everything Works Fine until if i have only 9 blog posts to show but when tenth post added then card-view gets messed up like 10 post shows both in 1st cardview item and in last cardview item.
below is the code to fill the Recyclerview Cardview
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_transaction);

what could be wrong?
am i doing something wrong?
what could be wrong?
You have a logic problem where you insert your data into the database, causing the same first item to show up as the 10th item. However, since you haven't shown the code, it's impossible to guess beyond that.
What have you done to debug your code?
am i doing something wrong?
Well, you have a bug ... so ... yes? :P
I have very popular question - why the data not showing in the RecycleView.
That is my Adapter:
public class CommentsAdapter extends RecyclerView.Adapter<CommentsAdapter.ViewHolder> {
private static final String TAG = "CommentsAdapter";
public ImageView mThumbView;
private List<PostComment> postCommentList;
public CommentsAdapter(List<PostComment> postCommentList) {
this.postCommentList = postCommentList;
}
#Override
public CommentsAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.post_comment_item, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(CommentsAdapter.ViewHolder holder, int position) {
PostComment record = postCommentList.get(position);
holder.mAuthorTextView.setText(record.getUser().getFull_name());
holder.mDateTextView.setText(record.getCreated_at());
holder.mTextTextView.setText(record.getText());
}
#Override
public int getItemCount() {
Log.i(TAG + " comments size", Integer.toString(postCommentList.size()));
return postCommentList.size();
}
public void addItems(List<PostComment> postCommentList) {
this.postCommentList.addAll(postCommentList);
}
public class ViewHolder extends RecyclerView.ViewHolder {
// each data item is just a string in this case
public TextView mAuthorTextView;
public TextView mDateTextView;
public TextView mTextTextView;
public ViewHolder(View v) {
super(v);
mAuthorTextView = (TextView) itemView.findViewById(R.id.comment_author);
mDateTextView = (TextView) itemView.findViewById(R.id.comment_date);
mTextTextView = (TextView) itemView.findViewById(R.id.comment_text);
}
}
}
That is my view:
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"

That is how I set up the adapter:
mLayoutManager = new LinearLayoutManager(this);
mLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
post_details_comments_list.setLayoutManager(mLayoutManager);
mCommentListAdapter = new CommentsAdapter(new ArrayList<PostComment>());
post_details_comments_list.setAdapter(mCommentListAdapter);
After I set up the adapter, I the getItemCount returns the quantity of the items - so that is not null.
RecycleView layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.google.android.gms.maps.MapView
android:id="#+id/post_details_mapview"
android:layout_width="wrap_content"
android:layout_height="200dp" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/post_details_comments_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/edit_comment"
android:hint="#string/hint_type_comment"/>
</LinearLayout>
I make the request to the server and here is the callback, where I get the results and set up the adapter:
#Override
public void onAllPostCommentsCallback(AllComments allComments) {
Log.i(TAG + " I've the comments", allComments.getPostCommentList().toString());
mCommentListAdapter.addItems(allComments.getPostCommentList());
post_details_comments_list.setAdapter(mCommentListAdapter);
mCommentListAdapter.notifyDataSetChanged();
}
But the list is not displaying.
What can be the reason?
put null inplace of parent in View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.post_comment_item, parent, false);
I've already solved the issue. The problem was that I had RecycleView inside the NestedScrollView
Answer in this post helped me a lot:
