NotifyDataSetChanged Recycler view : Cannot call this method while Recycler

I'm making a chat app. I have a recycler view. I use Picasso to download the images of the user and the friend he is chatting with. To not download the image for every message, when I download the first image I just put it into a bitmap and use it every time.
PROBLEM: I can't call NotifyDataSetChanged. I have tried every possible thing I've found on the net.
ERROR :
Cannot call this method while RecyclerView is computing a layout or scrolling android.support.v7.widget.RecyclerView
I have to "manually" refresh the view so that the images are loaded. No problem for the text.
It runs with the Handler but it doesn't even go in the function (so the view isn't refreshed).
Here is my code (everything works except this notifydatasetchanged)

It is because you're calling notifyDataSetChanged inside your onBindViewHolder like this:
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
...
((ItemMessageFriendHolder) holder).avata.setImageBitmap(BitmapFriend);
new Handler().post(new Runnable() {
#Override
public void run() {
notifyDataSetChanged();
}
});
...
}
You shouldn't force the Adapter to refresh itself before it isn't finished binding the view yet.
So, you need to remove the following code from your onBindViewHolder:
new Handler().post(new Runnable() {
#Override
public void run() {
notifyDataSetChanged();
}
});
then just call notifyDataSetChanged() when you need it. For example, when your dataset is changed.

Try this.
dialeecyclerView.post(new Runnable()
{
#Override
public void run() {
myadapter.notifyDataSetChanged();
}
});

How to sort recyclerView, Bold item if unread and unbold if item opened?

I have 2 Activities in my application.
activityMain contain 3 Fragments
The third fragment is a conversations list. This is a recylerView where each Item leads to a specific chat.
activityConversation contains a Chat.
First, i would like to sort the conversations in the the recyclerView in order of "Last actives". The most recent active should be displayed on top of the list, the second last active on second postition etc...
Secondly, each Item of the recyclerView contains a Textview. For each item, I would like to display the last message posted in the related chat in this Texview.
Finally, i would like to display these Item textViews in Bold since the conversation has not been opened until the last chat update.
Has anyone an Idea to help me achieve that?

Thank you in advance for your time.

maintain a flag in data level to know is it read or unread,based on that you can apply the styles.

There is two way to do this.
First you can ask to backend to write server side to query to handle last activity bases of timestamp .In this case you have to send your particular timestamp to server when you open particular conversation .
Other you can make local database ex-(sql database) and handle it in your own code by updating query when you reading or undreading conversation.

¿Why does not the recyclerView update the data obtained from Firebase instantly?

I'm using a recyclerView that inflates two types of views, to be able to do a chat, everything is fine but it is not sent or received instantly
When I send a message, it is not received unless I click on my edit text,
Which is wrong, because in a chat should show instantly...
My adapter:
public class ChatRecyclerAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
public Context context;
public ArrayList<ChatPersonal> items = new ArrayList<>();
private String mId;
private static final int CHAT_RIGHT = 1;
private static final int CHAT_LEFT = 2;
public ChatRecyclerAdapter (Context context, ArrayList<ChatPersonal> items, String mId){
this.context = context;
this.items = items;
this.mId = mId;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = null;
RecyclerView.ViewHolder holder = null;
switch (viewType){
case CHAT_RIGHT:
view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_chat_right, parent, false);
holder = new ChatPersonalHolderSender(view);
break;
case CHAT_LEFT:
view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_chat_left, parent, false);
holder = new ChatPersonalHolder(view);
break;
}
return holder;
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
ChatPersonal mObject = items.get(position);
int itemViewType = getItemViewType(position);
switch(itemViewType){
case CHAT_RIGHT:
((ChatPersonalHolderSender) holder).mMENSAJE.setText(mObject.getMessage());
((ChatPersonalHolderSender) holder).mHORA.setText(DateUtils.getRelativeTimeSpanString(mObject.getHour()));
break;
case CHAT_LEFT:
((ChatPersonalHolder) holder).mMENSAJE.setText(mObject.getMessage());
((ChatPersonalHolder) holder).mHORA.setText(DateUtils.getRelativeTimeSpanString(mObject.getHour()));
break;
}
}
#Override
public int getItemViewType(int position) {
if(items.get(position).getId().equals(mId)){
return CHAT_RIGHT;
}else{
return CHAT_LEFT;
}
}
#Override
public int getItemCount() {
return items.size();
}
}
And this is the relevant code of my chatClass:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_chat);
linearLayoutManager = new LinearLayoutManager(ActivityChat.this);
linearLayoutManager.setStackFromEnd(true);
mRecyclerView.setLayoutManager(linearLayoutManager);
mRecyclerView.setHasFixedSize(false);
adapter = new ChatRecyclerAdapter(getApplicationContext(), items, mId);
adapter.notifyDataSetChanged();
mRecyclerView.setAdapter(adapter);
// send message
mSentMensaje.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final String message = mEditText.getText().toString();
if (!message.isEmpty()) {
mChat.setMessage(message);
mChat.setHour(System.currentTimeMillis());
mChat.setId(mId);
if(mUser != null){
if(mUser.getIDchat() != null){
FirebaseUtils.getCHATT(mUser.getIDchat()).push().setValue(mChat).addOnSuccessListener(ActivityChat.this, new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
mRecyclerView.scrollToPosition(items.size() -1);
adapter.notifyDataSetChanged();
mEditText.setText("");
}
});
}}
// retreive message
if(mUser != null){
if(mUser.getIDchat() != null){
FirebaseUtils.getCHATT(mUser.getIDchat()).limitToFirst(50).addChildEventListener(new ChildEventListener() {
#Override
public void onChildAdded(DataSnapshot dataSnapshot, String s) {
if (dataSnapshot != null && dataSnapshot.getValue() != null) {
try{
ChatPersonal model = dataSnapshot.getValue(ChatPersonal.class);
items.add(model);
} catch (Exception ex) {
Log.e(TAG, ex.getMessage());
}
}
}
#Override
public void onChildChanged(DataSnapshot dataSnapshot, String s) {
}
#Override
public void onChildRemoved(DataSnapshot dataSnapshot) {
}
#Override
public void onChildMoved(DataSnapshot dataSnapshot, String s) {
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
// status
#Override
protected void onStart() {
super.onStart();
adapter.registerAdapterDataObserver(new RecyclerView.AdapterDataObserver() {
#Override
public void onChanged() {
super.onChanged();
mRecyclerView.scrollToPosition(adapter.getItemCount() - 1);
}
});
}
#Override
protected void onResume() {
super.onResume();
adapter.notifyDataSetChanged();
}
#Override
protected void onPostResume() {
super.onPostResume();
adapter.notifyDataSetChanged();
}
}

If you want the data to be synced with Firebase automatically, you need to use FirebaseRecyclerAdapter

First page of ViewPager not getting rendered

I am using a ViewPager to be able to swipe between views. The problem that I am facing is, the first page does not render properly(only the static members from layout file get rendered), but the second page and further pages are rendered properly. Also, when I go to third or later page and then come swiping back to the first page, it gets rendered perfectly.
I know that ViewPager loads the first page as well second page in the beginning and does the same for every next page. Is this the reason why my first page is not rendered properly? I am making a network call on each page and the data returned is being displayed on the page.
Here is the code for my Adapter:

just add this method to your Class
#Override
public int getItemPosition(Object object) {
return POSITION_NONE;
}
it will render every time when you enter to particular layout. this is the override method of pagerAdapter.
