Background
My app allows users to post images in specific categories and then allows users to tap on the posts to bring up a messaging activity
Problem
I currently have it setup so it is a global chat (any user could join and it was the same between all posts reading and writing from the same document) for testing purposes but I want to have it so it is a private chat between the two users. This was created using the real-time database I am in the process of migrating over to Firestore so I will also have to change the code for the "chatActivity"
What I have done
When the post is created it adds a new document to the messages collection for that post. The messages document name associated with that post is then stored in the post.
Where I am stuck
In my chat activity, I need to be able to get the id of the post so I can then retrieve the location of the document containing the messages related to that post
Objective
To be able to have the users post an image and have a document in the "Messages" collection be created DONE, then to have a second user come and see said image tap on it and then be able to open that document that was created for the image so the two users can then exchange messages between each other making it private between the two users because they are only reading from the document associated with that post
app workflow this should clear up any confusion
Database:
Code for writing post to database:
filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
final String downloadUrl =
uri.toString();
Log.d("tag", downloadUrl);
FirebaseUser current_user = FirebaseAuth.getInstance().getCurrentUser();
String uid = Objects.requireNonNull(current_user).getUid();
final Map<String, Object> postMap = new HashMap<>();
// No thumb ?????
postMap.put("image_url", downloadUrl);
postMap.put("desc", desc);
postMap.put("user_id", current_user_id);
postMap.put("message Doc", uid + postCategory);
postMap.put("timestamp", FieldValue.serverTimestamp());
firebaseFirestore.collection(postCategory).add(postMap).addOnCompleteListener(new OnCompleteListener<DocumentReference>() {
#Override
public void onComplete(#NonNull Task<DocumentReference> task) {
if (task.isSuccessful()) {
firebaseFirestore.collection("Posts").add(postMap).addOnCompleteListener(new OnCompleteListener<DocumentReference>() {
#Override
public void onComplete(#NonNull Task<DocumentReference> task) {
FirebaseUser current_user = FirebaseAuth.getInstance().getCurrentUser();
String uid = Objects.requireNonNull(current_user).getUid();

Where I Am Stuck
In my chat activity, I need to be able to get the id of the post so I
can then retrieve the location of the document containing the messages
related to that post
i am not sure, do you want to get all id or only one id ?
if you want to get the ALL id document of music collection from firestore, please add this in Your code:
public void loadAlltQueries(){
Query loadAllQueryId = firebaseFirestore
.collection("music")
.orderBy("timestamp", Query.Direction.DESCENDING);
loadAllQueryId.addSnapshotListener(new EventListener<QuerySnapshot>(){
#Override
public void onEvent(QuerySnapshot documentSnapshots, FirebaseFirestoreException e){
for (DocumentChange doc : documentSnapshots.getDocumentChanges()){
if (doc.getType() == DocumentChange.Type.ADDED){
String musicId = doc.getDocument().getId();
FriendlyMessage friendlyMessage = doc.getDocument().toObject(FriendlyMessage.class).withId(musicId);
mMessageAdapter.add(friendlyMessage);
mMessageAdapter.notifyDataSetChanged(); //for update adapter
}
}
}
});
}
and make MusicId.class
public class MusicId{
#Exclude
public String MusicId;
public <T extends MusicId> T withId(#NonNull final String id) {
this.MusicId = id;
return (T) this;
}
}
don't forget to add this in Your FriendlyMessage.class
public class FriendlyMessage extends MusicId {
// your constructor
// your getter
}
and from your adapter class get your getter
final String musicId = contentList.get(position).MusicId;
and Now you get your id CHur40Nr ..
if You are looking to get the id of the post that corresponds with whatever post was selected from the recycler view. Please make Adapter class, because holder method will get your post which you selected in this case holder for holder.setMessage(message);
public class AdapterFriendlyMessage extends RecyclerView.Adapter<FriendlyMessage.ViewHolder> {
public List<FriendlyMessage> contentList;
public Context context;
private FirebaseFirestore firebaseFirestore;
private FirebaseAuth firebaseAuth;
public AdapterFriendlyMessage(List<FriendlyMessage> contentList){
this.contentList = contentList;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.content_friendly_message, parent, false);
context = parent.getContext(); FriendlyMessage(container.getContext(), contentList);
firebaseFirestore = FirebaseFirestore.getInstance();
firebaseAuth = FirebaseAuth.getInstance();
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.setRecyclable(false);
// GET MusicId
final String musicId = contentList.get(position). MusicId;
final String currentUserId = firebaseAuth.getCurrentUser().getUid();
String uid = contentList.get(position).getUid();
firebaseFirestore.collection(" Music").document( musicId).collection("FriendlyMessage").get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>(){
#Override
public void onComplete(#NonNull Task<DocumentSnapshot> task){
if (task.isSuccessful()) {
String message = task.getResult().getString("message");
holder.setMessage(message); // this is what you want
}
}
});
}
#Override
public int getItemCount() {
return contentList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
private View mView;
private TextView txtMessage;
public ViewHolder(View itemView){
super(itemView);
mView = itemView;
}
public void setMessage(Sting text) {
txtMessage = mView.findViewById(R.id.text_view_mesage);
txtMessage.setText(text);
}
}
}
don't forget to passing id from firestore into Adapter
public class FriendlyMessageRoom extends Fragment {
private RecyclerView recyclerMessage;
private List<FriendlyMessage > contentList;
private AdapterFriendlyMessage adapterFriendlyMessage;
private FirebaseFirestore firebaseFirestore;
private FirebaseAuth mAuth;
public FriendlyMessageRoom() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_friendly_message_room, container, false);
mAuth = FirebaseAuth.getInstance();
firebaseFirestore = FirebaseFirestore.getInstance();
contentList = new ArrayList<>();
recyclerMessage = view.findViewById(R.id.recycler_message);
adapterFriendlyMessage = new AdapterFriendlyMessage(contentList);
recyclerMessage.setLayoutManager(new LinearLayoutManager(container.getContext()));
recyclerMessage.setAdapter(adapterFriendlyMessage);
return view;
}
#Override
public void onStart() {
super.onStart();
loadAlltQueries(); // please see firebase query that i write above
}
NOTE: my this answer might not answer your question accurately, since it hard to imagine what you want in the problem description.
Stop stressing yourself writing these boiler plate for retrieving data from firestore to recycler view. Take a look at Firebase UI for Cloud Firestore. Firebase UI for Cloud Firestore makes it simple to bind data from Cloud Firestore to your app's UI, thereby reducing boiler plate and may even help fix your problem. Add this- implementation 'com.firebaseui:firebase-ui-firestore:6.2.1' to dependency to use Firebase UI for Cloud Firestore

this is a status fragment , i want to make a module like WhatsApp status, here in the code above i am uploading the image on firebase storage that is working fine , image is being uploaded but in real-time database the image is not being uploaded.
I have attached the screenshot of my storage where data is being uploaded and also the screenshot of real time database where image is not being uploaded .
I have a profile activity that user upload their profile images, user uploads 2 images ( back and front) the images are showing fine in the profile activity, but I also want to show one of this image (back or front) in another activity ( ViewHolder activity ). I have tried many things but couldn't figure out as i am only testing how firebase works, I really appreciate if someone can help me here.

Here the screen shot to help more how I wanted
I put my comment in answer field because of this restriction: 'You must have 50 reputation to comment'.
Anyway, back to your question. One solution would be to save the current user 'key' to a SharedPreference file. In your new Activity, use that 'key' to retrieve the data from Firebase.
EDIT: Added solution
Quoted: "...and I want to show one of these image in my ViewHolder activity as you can see the text view (name and score are showing) which is coming from a ranking Fragment activity..."
Solution: Search for fixme. In RankingViewHolder class, add:
public class RankingViewHolder extends ...
//...
public TextView name_text, score_text;
public ImageView profileImageView; //fixme
//...
public RankingViewHolder(View itemView) {
//...
score_text = (TextView) itemView.findViewById(R.id.score_text);
profileImageView = (ImageView) itemView.findViewById(R.id.profile_image_view); //fixme
//...
Inside populateViewHolder()
viewHolder.score_text.setText(String.valueOf(model.getScore()));
Picasso.with(getContext()) //fixme
.load(Common.currentUser.getUrlProfilePic()) //fixme
.into(viewHolder.profileImageView); //fixme
Inside RankingFragment class, since you are already using Common.currentUser.getUserName(), might as well create another variable under it to store the url link to the user's profile picture, and retrieve the link via Common.currentUser.getUrlProfilePic().
EDIT#2:
The images stored in FB storage have this links:
gs://FIXME_FIREBASE.com/images/userName/userNameback.jpeg
gs://FIXME_FIREBASE.com/images/userName/userNameprofile.jpeg
However to use in Picasso, need this kind of links:
https://firebasestorage.googleapis.com/v0/b/FIXME/o/FIXME/images/userName/userNameback.jpeg?alt=media&token=FIXME
Question is how to get that?
One solution is that after you successfully upload the image, get the download url (example below).
The tricky part is that the download url is not immediately available, and you have to use .getMetadata(), .getDownloadUrl() to do that.
Once the url is received, you have to figure out how to save this link to the user's profile in your FB database.
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
StorageMetadata storageMetadata = taskSnapshot.getMetadata();
StorageReference reference = storageMetadata.getReference();
reference.getDownloadUrl() // Get the download URL for the file
.addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
Log.i(TAG, uri.toString()); //fixme: save this to user's profile
}
});
}
Inside populateViewHolder, you are using Ranking model that contains the username and score.
Modify that Ranking model class to add an additional String variable urlProfilePic that contains the url to the user's image (above result), and generate the getter for it called getUrlProfilePic(). Then you can use it in this way inside the populateViewHolder:
viewHolder.score_text.setText(String.valueOf(model.getScore()));
Picasso.with(getContext())
.load(model.getUrlProfilePic()) //fixme
.into(viewHolder.profileImageView);
I am currently working on a project that might be useful in a store for the ordering of foods. The device can already store some data and retrieve but there are problems that I have been dealing with.
Problem 1#: First off is that every time I store a data it usually looks like this:
For some reason I tried to use child "02" because it displays in the recycler view if I do something like "Ordering" as a child it does not seem to be showing in the display. How do I add more data to it like example in the child 02 I can still add like milkshakes or candy bars? This is the code I have done for storing.

How do I store many data and not needing for updating it?
Problem 2#: Retrieving of the data. The problem is that I can only seem to get only 1 data. I wanted to fix the store part first so that I could check if I could get the many information. This is my code for retrieving of the data.
public class Vieworders extends AppCompatActivity {
private RecyclerView mRecyclerView1;
private ViewHolder1 mAdapter1;
private DatabaseReference mDatabaseReference1;
private List<Model1> mModel1;
private FirebaseAuth mAuth;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_vieworders);
mRecyclerView1= findViewById(R.id.recyclerview1);
mRecyclerView1.setHasFixedSize(true);
mRecyclerView1.setLayoutManager(new LinearLayoutManager(this));
mModel1 = new ArrayList<>();
mAuth = FirebaseAuth.getInstance();
FirebaseUser user = mAuth.getCurrentUser();
String userID = user.getUid();
mAdapter1=new ViewHolder1(Vieworders.this, mModel1);
mRecyclerView1.setAdapter(mAdapter1);
mDatabaseReference1= FirebaseDatabase.getInstance().getReference(userID);
mDatabaseReference1.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot dataSnapshot) {
for(DataSnapshot postSnapshot:dataSnapshot.getChildren())
{

}
mAdapter1.notifyDataSetChanged();
}
#Override

Toast.makeText(Vieworders.this, databaseError.getMessage(), Toast.LENGTH_LONG).show();
}
});
}
Can someone help me, please? I really need this to be done.
I think you are able to send data to fire and able to store these datas.
Now ,this is my snipshots of fetching data from Firebase .You can take help from this code.

I am working on a Bus booking app.So whenever a user books a ride I will store his credentials(name,email) for that particular ride.But I also need to restrict the number of bookings for that ride(like only 20 per ride).To do this I am using firebase transactions.Initially i have the value at location mref1 as 0(zero),then i updated it using transactions,but when i run my code,for the very first time it doesn't get updated and afterwards it starts updating. Can anyone tell me how? Below is my code for database(mref1 is the location where I want to store the number of bookings)My Database structure`
private DatabaseReference mDatabase1;
private DatabaseReference mDatabase2;
private DatabaseReference mref1;
private DatabaseReference mref2;
private FirebaseAuth mAuth;
private static final String TAG = "BookingActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_booking);
mAuth = FirebaseAuth.getInstance();
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mDatabase1 = FirebaseDatabase.getInstance().getReference().child("Time1");
mDatabase2 = FirebaseDatabase.getInstance().getReference().child("Time2");
mref1 = FirebaseDatabase.getInstance().getReference().child("Count#Time1");
mref2 = FirebaseDatabase.getInstance().getReference().child("Count#Time2");
findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Book(mDatabase1,mref1);
}
});
findViewById(R.id.button2).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Book(mDatabase2,mref2);
}
});
}
public void Book(DatabaseReference mDatabase,DatabaseReference mref) {
final FirebaseUser user = mAuth.getCurrentUser();
HashMap<String,String>datamap = new HashMap<>();
if(user!=null) {
datamap.put("Name", user.getDisplayName());
datamap.put("Email", user.getEmail());
}
mDatabase.push().setValue(datamap);
Update(mref);
Toast.makeText(BookingActivity.this, "Booked Successfully", Toast.LENGTH_SHORT).show();
}
public void Update(DatabaseReference mDatabase) {
mDatabase.runTransaction(new Transaction.Handler() {
#NonNull
#Override
public Transaction.Result doTransaction(#NonNull MutableData mutableData) {
Integer CurrentValue = mutableData.getValue(Integer.class);
mutableData.setValue(CurrentValue+1);
return Transaction.success(mutableData);
}
#Override
public void onComplete(#Nullable DatabaseError databaseError, boolean b, #Nullable DataSnapshot dataSnapshot) {
Log.d(TAG, "Updating count transaction is completed.");
}
});
}
}
According to the anwer from this post and seeing your code, to solve the issue, I recommend you first to check nullity using the following line of code:
if(CurrentValue != null) {}
I'm trying to JUnit test this class:
public class WeekListActivity extends AppCompatActivity implements AdapterView.OnItemClickListener {
private ArrayList<String> weekList = new ArrayList<>();
private ArrayAdapter<String> adapter;
ListView weekListView;
Button AddWeekButton;
EditText InsertWeekEditText;
String weekNumber;
String subjectName;
String subjectCode;
User user;
DatabaseReference mDatabase;
DatabaseReference mRef;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_week_list);
FirebaseApp.initializeApp(this);
FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
Intent moveToDetailIntent = this.getIntent();
subjectName = moveToDetailIntent.getExtras().getString("Subject");
subjectCode = moveToDetailIntent.getExtras().getString("Fagkode");
mDatabase = FirebaseDatabase.getInstance().getReference().child("Studentfag").child(subjectCode).child("Week");
mRef = FirebaseDatabase.getInstance().getReference().child("Users").child(firebaseUser.getUid()).child("User info");
weekListView = (ListView) findViewById(R.id.WeekListView);
AddWeekButton = (Button) findViewById(R.id.AddWeekButton);
InsertWeekEditText = (EditText) findViewById(R.id.InsertWeek);
String userID = firebaseUser.getUid();
mRef.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
user = dataSnapshot.getValue(User.class);
if (user.isStudent){
View a = weekListView;
a.setMinimumHeight(80);
View b = AddWeekButton;
b.setVisibility(View.GONE);
View c = InsertWeekEditText;
c.setVisibility(View.GONE);
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
adapter = new ArrayAdapter<String>(getBaseContext(), android.R.layout.simple_list_item_1, weekList);
weekListView.setAdapter(adapter);
weekListView.setOnItemClickListener(this);
AddWeekButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
weekNumber= InsertWeekEditText.getText().toString();
mDatabase.child(weekNumber).child("id").setValue(weekNumber);
}
});
mDatabase.addChildEventListener(new ChildEventListener() {
#Override
public void onChildAdded(DataSnapshot dataSnapshot, String s) {
String week = dataSnapshot.getKey().toString();
weekList.add("Week: " + week);
adapter.notifyDataSetChanged();
}
#Override

});
}
The problem is that when I build a new activity in my setup method it complains because this sentence:
mRef = FirebaseDatabase.getInstance().getReference().child("Users").child(firebaseUser.getUid()).child("User info");
is not able to build, when we don't have a firebase user.
Therefore I tried to Mock a firebaseuser in my testclass. The question is, how can I tell the class that it should use the mocked firebaseuser in onCreate? Is there a way to "send" the mocked object over? Thanks!
The beginning of my setup method:
#Before
public void setUp() throws Exception {
Intent i = new Intent();
i.putExtra("Subject", "Matematikk 1");
i.putExtra("Fagkode", "TMA4100");
FirebaseUser mockFirebaseUser = mock(FirebaseUser.class);
when(mockFirebaseUser.getUid()).thenReturn("uTZpVPPz8NT2LOvP4ufjs1L6r3P2");
Activity activity = Robolectric.buildActivity(WeekListActivity.class).withIntent(i).create().get();
}
As usual, I suggest everybody to not mix presentation and storage code. And this is a question for another topic.
And here the trick how you can achieve what you want.
First, extract method for Firebase initialisation and providing FirebaseAuth:
#VisibleForTest
#NonNull
FirebaseAuth initAndReturnFirebaseAuth() {
FirebaseApp.initializeApp(this);
FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
}
Second, create test activity and override this method:
public class TestWeekListActivity extends WeekListActivity {
#Override
#NonNull
FirebaseAuth initAndReturnFirebaseAuth() {
FirebaseAuth authMock = mock(FirebaseAuth.class);
when(authMock.getCurrentUser()).thenReturn(mockFirebaseUser);
return authMock;
}
}
And then use test activity in test instead of you real activity.
Hope it helps!
