I upload some html text (which contains img tags) to Firestore(images are uploaded to firebase storage). When i try to get these html data to display onto a webview i only get text, no images
Here is the code i used to upload HTML to FireStore
storageReference.child(System.currentTimeMillis() + ".png").putFile(file_uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
post_img_url = String.valueOf(taskSnapshot.getDownloadUrl());
String HTML = editor.getContentAsHTML().replace(uuid_, post_img_url);
Question_model question_model = new Question_model(mAuth.getUid(), HTML);
mFireStoredbReference.collection("Questions").add(question_model).addOnCompleteListener(new OnCompleteListener<DocumentReference>() {
#Override
public void onComplete(#NonNull Task<DocumentReference> task) {
Toast.makeText(Forum.this, "Question added", Toast.LENGTH_SHORT).show();
startActivity(new Intent(Forum.this, ListQuestions.class));
finish();
}
});
}
});
And i try to take this data from the Questions collection
firebaseFirestore.collection("Questions").addSnapshotListener(new EventListener<QuerySnapshot>() {
#Override
public void onEvent(#Nullable QuerySnapshot queryDocumentSnapshots, #Nullable FirebaseFirestoreException e) {
if (e instanceof com.google.firebase.firestore.FirebaseFirestoreException) {
// Log.d(TAG, "onEvent: The error is " + e);
} else {
try {
for (DocumentChange doc : queryDocumentSnapshots.getDocumentChanges()) {
if (doc.getType() == DocumentChange.Type.ADDED) {
Question_model model = doc.getDocument().toObject(Question_model.class);
question_modelList.add(model);
questionAdapter.notifyDataSetChanged();
}
}
} catch (Exception e2) {
}
}
}
});
Here is my adapter for the recyclerview
public class QuestionAdapter extends RecyclerView.Adapter<QuestionAdapter.MyViewHolder> {
Context ctx;
FirebaseFirestore mFirebaseFirestore;
private List<Question_model> question_modelList;
public QuestionAdapter(List<Question_model> question_modelList, Context ctx) {
this.question_modelList = question_modelList;
this.ctx = ctx;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.question_individual, parent, false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(final MyViewHolder holder, int position) {
mFirebaseFirestore = FirebaseFirestore.getInstance();
String user_id = question_modelList.get(position).getUser_id();
mFirebaseFirestore.collection("users").document(user_id).get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
#Override
public void onComplete(#NonNull Task<DocumentSnapshot> task) {
if (task.isSuccessful()) {
holder.user_name.setText(task.getResult().getString("user_name"));
} else {
}
}
});
Log.d("Asis", "onBindViewHolder: "+question_modelList.get(position).getContent_html());
holder.question.loadData(question_modelList.get(position).getContent_html(),"text/html","utf-8");
}
#Override
public int getItemCount() {
return question_modelList.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder {
TextView user_name;
WebView question;
public MyViewHolder(View itemView) {
super(itemView);
user_name = itemView.findViewById(R.id.user_name);
question = itemView.findViewById(R.id.question);
question.getSettings().setJavaScriptEnabled(true);
question.getSettings().setLoadsImagesAutomatically(true);
question.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_COMPATIBILITY_MODE);
question.getSettings().setDomStorageEnabled(true);
}
}
}
you can use Glide to easily download images from Firebase storage.First, add FirebaseUI to your app/build.gradle:
dependencies {
// FirebaseUI Storage only
implementation 'com.firebaseui:firebase-ui-storage:0.6.0'}
Then you can load images directly from Storage:
Glide.with(this /* context */)
.using(new FirebaseImageLoader())
.load(/*storageReference*/)
.into(/*yourView*/);

I'm trying to retrieve some simple data from my database as an Admin, the data has been retrieved, but nothing is shown on the recyclerview.
In the other hand, i was trying to assign a value (String) from the database to a TextView, i was recieving the value, but the TextView was empty, i went to the .xml file and changed the layout_width from android:layout_width="wrap_content" to android:layout_width="match_parent" and it worked! Before that with the simple Firebase Client SDK it was showing the texte even with android:layout_width="wrap_content"
PS: Since i started using the Firebase Admin SDK, I didn't had any issues with writing data to the Realtime database, Or with creating Users. I tried both of them and they works fine.
Here's the retrieving function :
private void RetriveClasses() {
// Get a reference to our posts
final FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference ref = database.getReference("Classrooms");
mclassrooms.clear();
// Attach a listener to read the data at our posts reference
ref.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for (DataSnapshot snapshot : dataSnapshot.getChildren())
{
Classroom post = snapshot.getValue(Classroom.class);
if (!post.getDeleted().equals("true"))
{
mclassrooms.add(post);
}
mAdapter.notifyDataSetChanged();
System.out.println(post.getClassName());
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
System.out.println("The read failed: " + databaseError.getCode());
}
});
}
The System.out.println(post.getClassName()); Shows :
I/System.out: L1 ST 2022-2023
L1 ST 2021-2022
L1 ST 2015-2016
These are the class names i'm looking for, which means the reading is succeed, but the recyclerview still won't show any items.
here's my Adapter:
public class ClassroomsAdapter extends RecyclerView.Adapter<ClassroomsAdapter.ViewHolder> {
private Context c;

public ClassroomsAdapter(List<Classroom> mclassrooms) {
this.mclassrooms = mclassrooms;

I have CardViews in RecyclerView and each one has a delete button, when clicked it deletes data from database, remove item from ArrayList on that position and runs the animation.
When deleted it dissapears and creates a copy of it self ,Toast shows that ArrayList is empty/ without that item, but its still there I can click on it and everything, only after refreshing fragment(Changing to another fragment in bottom navigation tab or clicking on the same one) it dissapears.
This is my Adapter:

This is part of code in fragment that deletes item:

});
}else{

.document(mAuth.getCurrentUser().getUid())
.collection("Saved Kits")
.document(kitlist.get(position).getName())
.delete();
}
Toast.makeText(getContext(), kitlist.toString(), Toast.LENGTH_SHORT).show();
handler.postDelayed(new Runnable() {
#Override
public void run() {
Animation anim = AnimationUtils.loadAnimation(getContext(), R.anim.zoomout);
card.startAnimation(anim);
handler.postDelayed(new Runnable() {
#Override
public void run() {
if(kitlist.isEmpty()){
emptTxt.setVisibility(View.VISIBLE);
kitlist.remove(position);
rec.removeViewAt(position);
adapter.notifyItemRemoved(position);
}
}
},300);
}
}, 150);
}
I tried these combinations:
kitlist.remove(position);
rec.removeViewAt(position);
adapter.notifyItemRemoved(position);
//This one you can see in code above
kitlist.remove(position);
adapter.notifyDataSetChange(position)
And tried making onKitDelete default and using notfiy()/notifyAll()
public interface OnKitClickListener{
void onKitClick(int position, String NameS, String kcalS, String protS, String uhS, String mastS, int dayNums);
void onKitAdd(int position, ImageView addShare, String NameS);
default void onKitDelete(int position, CardView card, String userID){
notify();
}
}
I always get same resoult.
that's easy to update your recycler view with
android ViewModel architechtureAndroid ViewModel Docs
I'm writing a small group chat application in Android Studio and using Firebase as the backend. I'm trying to allow the users to post images however everytime I send an image to firebase storage and retrieve it in order to post into a recycler view using Glide, it duplicates in the recycler view. I've confirmed the image in the firebase storage is NOT duplicating, it's just on the recycler view on the app itself. I've been struggling with this issue for days and cannot for the life of me find why it's duplicating.
Here's my code:
Uploads and Retrieves the image URL in Firebase
public void uploadImage(final Uri filePath) {
if (filePath != null) {
final String pathToImage = "chatImages/" + user.getUid()+"/"+ UUID.randomUUID();
StorageReference storeRef = storageReference.child(pathToImage);
UploadTask uploadTask = storeRef.putFile(filePath);
uploadTask.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.e(TAG, "Upload Failed");
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Log.e(TAG, "Upload Successful");
//now that the image has been uploaded, send to chat
storageReference.child(pathToImage).getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
//adds photo, username and message to the arraylists\
imagePath = uri.toString();
Log.e(TAG, "done");
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.e(TAG, "Failed to Retrieve Image Message");
}
});
}
});
}
}
Adds the image and other post info to the recycler view
db.collection("chats").document("0fv4XvLpi8dWivyohQbk").collection("chatMessages")
.orderBy("TimeStamp")
.addSnapshotListener(new EventListener<QuerySnapshot>() {
#Override
public void onEvent(#Nullable QuerySnapshot queryDocumentSnapshots, #Nullable FirebaseFirestoreException e) {
if (e != null) {
Log.e(TAG, "Listen Failed", e);
return;
}
//temporay arraylists
final ArrayList<String> uIdAL = new ArrayList<>();
//gets any updates
for (DocumentChange newdoc : queryDocumentSnapshots.getDocumentChanges()) {
if (newdoc.getType() == DocumentChange.Type.ADDED) {
Log.e(TAG, "new message" + newdoc.getDocument().getData());
//saves userIDs for later use in getting profile pics
uIdAL.add((String) newdoc.getDocument().getData().get("userID"));
//temporary profile picture
if(chatPhotoUrl != null && ((String) newdoc.getDocument().getData().get("userID")).equals(user.getUid()))
{
messageAvatars.add(chatPhotoUrl.toString());
}
else
{
messageAvatars.add("https://pictures.digitalrev.com/image/upload/v1454493563/gzev2fhfpoizg3bpozjr.jpg");
}
//get usernames and messages
userNames.add((String) newdoc.getDocument().getData().get("userName"));
messages.add((String) newdoc.getDocument().getData().get("message"));
imageMessages.add((String) newdoc.getDocument().getData().get("imageMessage"));
//add to recycler view
adapter.notifyItemInserted(userNames.size());
rv.scrollToPosition(userNames.size() - 1);
Log.e(TAG, "here");
}
}
}

Please help me guys!. Thanks in Advance!.
TheRecyclerView has ability to show items in multiple types.
In your case you can define two ViewType. one for Images and another for Videos.
Search about RecyclerView with multiple view types.
Take a look at here and this.
Also here is a question and answers about it.
I am creating a program, where user can update post, and other user and same user can react there. For that, I have implemented the love button. So this works this way, I have saved a unique id in the DatabaseReference and other reference for uniquekey for easiness. So, whenever, the user clicks on love button, it must update the total reaction of the node by increasing it to one. The problem I am getting is, whenever I press the love button key, it doesn't call the uniqueID I need. The uniqueId I am getting from model class from viewholder is not the post I have reacted to.
