Firebase Chat Recycler View Left and Right View Not Working Android

Hi I want the chat message Align like this when I send message I want them on the right when I receive I want them on left like this in the image
but it looks like this even though I set to two different layouts for in and out but it appears in the same way
In ChatRoomActvity getItemViewType(int position) always return as MESSAGE_IN_VIEW_TYPE;
What am I missing here?

I can't without the images (for any reason, they are not in the post) but from what I see,
getItem(position).getId().equals(mFirebaseAuth.getCurrentUser().getUid())
and
FriendlyMessage.getId()
I'd say you're not taking the sender into account. ID is conventionally used as a message number, they usually do not point to a uid. Besides, your class already has a field called senderUid, so you should compare against that instead of id.
Optionally, try to log the line before the condition.

#Override
public int getItemViewType(int position) {
FriendlyMessage friendlyMessage = getItem(position);
boolean user = (friendlyMessage.getUserid().equals(mUserid));
if(user)
{
return MESSAGE_OUT_VIEW_TYPE;
} else {
return MESSAGE_IN_VIEW_TYPE;
}
}
I use boolean

for (DataSnapshot userDataSnapshot : dataSnapshot.getChildren()) {
UserOrders order = userDataSnapshot.getValue(UserOrders.class);

MYShowOrderBtn.setEnabled(true);
}else if (state.equals("Not Payments")){
MYConfirmPayments.setEnabled(false);

}
#Override

// Getting Post failed, log a message

I want to display the children: ticketCategory, subcategory and status.
I will highly appreciate any help.
thank you!!

}
public static ArrayList<Ticket> getTicket()
{
ArrayList<Ticket> tickets = new ArrayList<Ticket>();
return tickets;
}}

Just make your ticket class as serializable and pass it in bundel and parse in other activity like bellow
First change your Ticket class definition like bellow
public class Ticket implements Serializable {
Then after change your click code like bellow
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent intent = new Intent(view.getContext(), ComplaintDetail.class);
intent.putExtra("ticket", ticket);
startActivity(intent);
}
});
And finally parse and get your object in second activity like bellow
Ticket ticket= (Ticket) getIntent().getSerializableExtra("ticket");

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent intent = new Intent(view.getContext(), ComplaintDetail.class);
intent.putExtra("ticket", ticket);
startActivity(intent);
}
});
The object i mentioned ticket in intent is the object u receive from fireabse and you need make a object parceable to be able to send it to another activity.So, make sure sure to make it parceable.
The below is the model class with implementing parceable interface:-
public class Ticket implements Parcelable {
private String ticketCategory;
private String name;
private String complaintID;
private String subcategory;
private String priority;
private String status;
private String comments;
private String cannedReply;
public Ticket() {
}
public Ticket(String ticketCategory, String subcategory, String priority, String status, String comments, String cannedReply) {
this.ticketCategory = ticketCategory;
// this.Name = Name;
this.subcategory = subcategory;
this.priority = priority;
this.status = status;
this.comments = comments;
this.cannedReply = cannedReply;
}
public String getTicketCategory() {
return ticketCategory;
}
public void setTicketCategory(String ticketCategory) {
this.ticketCategory = ticketCategory;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getComplaintID() {
return complaintID;
}
public void setComplaintID(String complaintID) {
this.complaintID = complaintID;
}
public String getSubcategory() {
return subcategory;
}
public void setSubcategory(String subcategory) {
this.subcategory = subcategory;
}
public String getPriority() {
return priority;
}
public void setPriority(String priority) {
this.priority = priority;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getComments() {
return comments;
}
public void setComments(String comments) {
this.comments = comments;
}
public String getCannedReply() {
return cannedReply;
}
public void setCannedReply(String cannedReply) {
this.cannedReply = cannedReply;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.ticketCategory);
dest.writeString(this.name);
dest.writeString(this.complaintID);
dest.writeString(this.subcategory);
dest.writeString(this.priority);
dest.writeString(this.status);
dest.writeString(this.comments);
dest.writeString(this.cannedReply);
}
protected Ticket(Parcel in) {
this.ticketCategory = in.readString();
this.name = in.readString();
this.complaintID = in.readString();
this.subcategory = in.readString();
this.priority = in.readString();
this.status = in.readString();
this.comments = in.readString();
this.cannedReply = in.readString();
}
public static final Parcelable.Creator<Ticket> CREATOR = new Parcelable.Creator<Ticket>() {
#Override
public Ticket createFromParcel(Parcel source) {
return new Ticket(source);
}
#Override
public Ticket[] newArray(int size) {
return new Ticket[size];
}
};
}
So,I have the set and get methods and implemented the parceable i.e made the class parceable so that u can send the entire object.Now in other activity where you will be receiving,You can just use get methods like below
First get the intent through getIntent() in onCreate and declare the object Ticket.
ticket = getIntent().getParcelableExtra("Ticket");
And where you need the object there you can directly access it like below
ticket.getSubcategory();
ticket.getTicketCategory();
ticket.getStatus();
So,Thats it ask me if you didn't get any thing and if it is not working.

RecyclerView to Firebase database

I actually want cardView in my RecyclerView to retrieve data from firebase but it returns error. Please do help me to attach my RecyclerView to firebase and retrieve data from it.
Thanking you in advance.
Here is the mainActivity.java
mbloglist = findViewById(R.id.rv1);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
productAdapter adapter = new productAdapter(this);

for(DataSnapshot child : dataSnapshot.getChildren()){
ModelClass modelClass = child.getValue(ModelClass.class);
modelClassList.add(modelClass);
}

Here is the Firebase Realtime Database Image

ModelClass class and your database doesn't have the same structure, because in your database you have a new node called "phone" inside each userID node.
You can try 3 approaches to solve this issue:
a.) Write data in your database just like ModelClass is, without "phone" node.
b.) Create a new class called "Phone" with same attributes you have inside "phone" node in the database, and make this new class part of ModelClass class.
c.) On myRef onDataChange method, inside for statement, check for each child key and fill ModelClass atributes one by one. When the child key is equal to "phone", start a new loop statement in "phone" children to fill these attributes.

Add the following code:
#Override
public int getItemCount() {
return productList.size();
}
