Snapshot
As your attached screenshot,
please make sure all images and icons used in the app are lower sizes even loading dynamic images for that you can use tinypng.com or tinyjpg.com
also, using pagination in RecyclerView will improve your app performance.
and make sure JSON/XML list response is minimal.

OUTPUT
The size of folderList is 2
I also check the size of adapter. It is also 2
I also tried by making a new Adapter but it also does not work.
I don't know where I am making mistake and why it is now showing nothing in activity.
Change 1 :
In the xml set attribute android:layout_width="0dp" to android:layout_width="match_parent" and android:layout_height="0dp" to android:layout_height="match_parent"
Change 2 :
In your MainActivity code set LayoutManager to the RecyclerView before setting up adapter. so the code goes this way :
//Defining RecyclerView and setting LayoutManager
RecyclerView recyclerView = binding.folderRecyclerView;
FolderListAdapter adapter = new FolderListAdapter(this, folderList);
//Setting up Adapter
recyclerView.setLayoutManager(new GridLayoutManager(this, 2));
recyclerView.setAdapter(adapter);
I am developing an android chat app and I would like the messages of the user you are chatting with to be aligned to the right and their messages to be aligned to the left. This is the condition that allows you to distinguish who the message belongs to, I can only write it on the bindview holder:
if(model.getUidSender().equals(fAuth.getCurrentUser().getUid()))
But how do I align the item to the right or left?
I have also thought about inflating two different layouts but I should go and operate in the CreateViewHolder in which I would not have the model.getUidSender value. How can I solve this problem?
This is my complete code:
#Override
protected void onStart() {
super.onStart();
CollectionReference collectRefMessage = FirebaseFirestore.getInstance().collection("roomChat")
.document("rooms")
.collection(chatId).document("message")
.collection("messages");
FirestoreRecyclerOptions<getMessage> options
= new FirestoreRecyclerOptions.Builder<getMessage>()
.setQuery(collectRefMessage.limit(1000).orderBy("date", Query.Direction.ASCENDING), getMessage.class)
.build();
FirestoreRecyclerAdapter<getMessage, getASetMsg> firestoreRecyclerAdapter = new FirestoreRecyclerAdapter<getMessage, getASetMsg>(options) {
#Override
protected void onBindViewHolder(#NonNull #NotNull getASetMsg holder, int position, #NonNull #NotNull getMessage model) {
holder.txtMsgText.setText(model.getText());
holder.dateATime.setText(model.getDate());
// uidCh = model.getUidSender();
//if(model.getUidSender().equals(fAuth.getCurrentUser().getUid()))
}
#NonNull
#NotNull
#Override
public getASetMsg onCreateViewHolder(#NonNull #NotNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_chat,parent,false);
getASetMsg viewHolder = new getASetMsg(view);
return viewHolder;
}
};
rView.setAdapter(firestoreRecyclerAdapter);
firestoreRecyclerAdapter.startListening();
}
public static class getASetMsg extends RecyclerView.ViewHolder {
TextView txtMsgText, dateATime;
public getASetMsg(#NonNull View itemView) {
super(itemView);
txtMsgText = itemView.findViewById(R.id.txtMsgText);
dateATime = itemView.findViewById(R.id.dateATime);
}
}
I managed to solve it like this:
if(model.getUidSender().equals(fAuth.getCurrentUser().getUid())) {
final FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) holder.messageCard.getLayoutParams();
params.gravity = GravityCompat.END; // or GravityCompat.END
holder.messageCard.setLayoutParams(params);
}
So, this is the chat card layout:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_width="wrap_content"

app:cardBackgroundColor="#color/textC"

android:layout_marginTop="25dp"
android:layout_marginBottom="20dp"
android:textSize="22dp"/>

android:layout_marginTop="5dp"
android:textColor="#color/white"
android:layout_marginLeft="30dp"
/>
</RelativeLayout>
</com.google.android.material.card.MaterialCardView>
</FrameLayout>
I tried a lot of solutions but no solution has worked for me.
I am getting data from the server and showing it inside a recycleview. The data shows fine but shows this error in the logcat
Access denied finding property "persist.vendor.log.tel_dbg"
E/RecyclerView: No adapter attached; skipping layout
E/RecyclerView: No adapter attached; skipping layout
sometimes when I refresh again and again the recyclerview becomes empty.
I am using viewpager consisting of 2 fragments inside a parent fragment.
this recycleview is using in a nested scrollview
some time data not showing
Code snippet:
homebuyer_adapter_recycler=new homebuyer_adapter_recycle(getActivity(), items);
LinearLayoutManager home = new LinearLayoutManager(getActivity());
home.setOrientation(LinearLayoutManager.VERTICAL);
allitemsgrid.setLayoutManager(home);
allitemsgrid.setAdapter(r);

In error it is saying that the Adapter for RecylerView is not attached. So, try to add adapter to the layout using:
recyclerView.setAdapter(categoryAdapter);
I am assuming homebuyer_adapter_recycler is your adapter.
According to that, you haven't really set your adapter as the logcat is specifying.
Add the below code instead of allitemsgrid.setAdapter(r);
allitemsgrid.setAdapter(homebuyer_adapter_recycler);
If my assumption or suggestion is wrong, it is okay. It is probably because your question is not very clear and does not provide the necessary details. Please provide more details such as the adapter class code and what is allitemsgrid, homebuyer_adapter_recycler and r.
Before marking as duplicate et al, viewpager from recyclerview is kind of triccky. The code is able to retrieve data from db and display it in a recyclerview with cardview. I want to be able to scroll the images in the viewpager while in the recyclerview as shown in the wireframe below, the dots represent number of images retrieved from DB which should be swipeeable right or left. Imageview seems not to be swipeable.

I want to create dynamic views with x number of rows for each CardView that gets created. To help illustrate my idea this image shows what I essentially want to do.
For each CardView I want to be able to put any amount of TableRows into the CardView. So one CardView could have 4 rows whereas the next CardView could have 2 rows and so on.
EDIT: Implementation
Essentially this view is replicated several times, I would like to minimise having to write seperate layouts for each CardView with x amount of rows like in the Card Storage implemenation which is more reusable than what I currently have. As I hit the limit here, I have posted a pastebin of the current layout with rows that I have
