i am trying to update recycler view when the user sends and removes friend request ..i am using firebase firestore..when one user sends the friend request request is shown in recycler view and when request is canceled the user is not removed from the list i am using following code,,
case ADDED:
Log.d(TAG, "onEvent: " + dc.getDocument().toString());
if (state.equals("recieved")) {
mDb.collection("users").document(userId)
.get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
@Override
public void onComplete(@NonNull Task<DocumentSnapshot> task) {
Log.d(TAG, "onComplete: CheckingifTAskComplete");
if (task.isSuccessful()) {
Log.d(TAG, "onComplete: tassk: succes :" + task.getResult());
DocumentSnapshot snapshot = task.getResult();
Users users = new Users(snapshot.getString("id"),
snapshot.getString("display_name"),
snapshot.getString("status"),
snapshot.getString("profile_image"),
snapshot.getString("thumb_image"));
Log.d(TAG, "onComplete: useradded" + users.toString());
mUSerRequestList.add(users);
adapter.notifyItemInserted(adapter.getItemCount()-1);
}
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.d(TAG, "onFailure: Failed");
}
});
on remove:
case REMOVED:
Log.d("TAG", "Removed Msg: " + dc.getDocument());
mDb.collection("users").document(userId)
.get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
@Override
public void onComplete(@NonNull Task<DocumentSnapshot> task) {
Log.d(TAG, "onComplete: CheckingifTAskComplete");
if (task.isSuccessful()) {
Log.d(TAG, "onComplete: tassk: succes :" + task.getResult());
DocumentSnapshot snapshot = task.getResult();
Users users = new Users(snapshot.getString("id"),
snapshot.getString("display_name"),
snapshot.getString("status"),
snapshot.getString("profile_image"),
snapshot.getString("thumb_image"));
for (Users removeUser: mUSerRequestList) {
if (removeUser.getId().equals(users.getId())){
mUSerRequestList.remove(users);
adapter.notifyItemRemoved(mUSerRequestList.indexOf(users.getId()));
break;
}
}
}
}
});
break;
my recycler view adapter:
public class RequestsRecyclerViewAdapter extends RecyclerView.Adapter<RequestViewHolder> {
private static final String TAG = "RequestsRecyclerViewAda";
ArrayList<Users> mList;
private Context mainActivityContext;
static RequestViewHolder ho;
public RequestsRecyclerViewAdapter(Context mainActivityContext, ArrayList<Users> mList) {
this.mList = mList;
this.mainActivityContext = mainActivityContext;
}
@NonNull
@Override
public RequestViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int position) {
Log.d(TAG, "onCreateViewHolder: inflatingUserActivity");
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View view = inflater.inflate(R.layout.snippet_user_request_single, parent, false);
Log.d(TAG, "onCreateViewHolder: CallingUSersViewHolder");
return new RequestViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull final RequestViewHolder holder, final int position) {
ho = holder;
Log.d(TAG, "onBindViewHolder: RequestUSerGot: " + mList.get(position).toString());
Log.d(TAG, "onBindViewHolder: " + holder.mName);
holder.mName.setText(mList.get(position).getDisplay_name());
Picasso.get()
.load(mList.get(position).getThumb_image())
.networkPolicy(NetworkPolicy.OFFLINE)
.placeholder(R.drawable.ic_launcher_foreground)
.into(holder.mProfileImage, new Callback() {
@Override
public void onSuccess() {
}
@Override
public void onError(Exception e) {
Picasso.get()
.load(mList.get(position).getThumb_image())
.placeholder(R.drawable.ic_launcher_foreground)
.into(holder.mProfileImage);
}
});
Log.d(TAG, "onBindViewHolder: picassoLoaded");
addonClickListners(holder);
}
private void addonClickListners(RequestViewHolder holder) {
holder.mAccept.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(mainActivityContext, "Added", Toast.LENGTH_SHORT).show();
}
});
holder.mCancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(mainActivityContext, "Canceld", Toast.LENGTH_SHORT).show();
}
});
}
@Override
public int getItemCount() {
return mList.size();
}
}
view holder:
public class RequestViewHolder extends RecyclerView.ViewHolder {
public CircleImageView mProfileImage;
public TextView mName;
public ImageButton mAccept, mCancel;
public RequestViewHolder(@NonNull View itemView) {
super(itemView);
mProfileImage = itemView.findViewById(R.id.requestFPRofileImage);
mName = itemView.findViewById(R.id.requestFName);
mAccept = itemView.findViewById(R.id.requestFAccept);
mCancel = itemView.findViewById(R.id.requestFCancel);
}
}
