I have a nested recycler view on which child item click I want the whole child recycler view to set visibility GONE.
I have tried some way to do it. But keeps on loosing the recycler view state and wrong data show's up. Help, please.
Here is ParentAdapter.java code

if (onItemClickListener != null) {
deepLinkText.setOnClickListener(v -> {
onItemClickListener.onItemClick(getAdapterPosition(), parentPos);
});
}
}
}
}
Here is my Click Listener Code in the Activity:
#Override
public void onItemClick(int childPos, int parentPos) {
if (TextUtils.isEmpty(chatMessageList.get(parentPos).getData().get(childPos).getDeeplink())) {
String message = chatMessageList.get(parentPos).getData().get(childPos).getText();
if (!viewModel.sendMessage(message)) {
setMessage(getString(R.string.error_something_went_wrong), ChatBotManager.UserType.BOT.toString());
} else {
messageListAdapter.onSelected(parentPos);
setMessage(message, ChatBotManager.UserType.USER.toString());
}
} else {
if (TextUtils.equals(chatMessageList.get(parentPos).getData().get(childPos).getDeeplink(), "restart")) {
if (messageListAdapter != null) {
messageListAdapter.clearData();
viewModel.sendMessage("start");
}
} else {
String uri = chatMessageList.get(parentPos).getData().get(childPos).getDeeplink();
Intent newIntent = new Intent(ApplicationClass.getContext(), TalkLinkingActivity.class);
newIntent.setData(Uri.parse(uri));
newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(newIntent);
finish();
}
}
}
Please help what I am missing here, My goal is to have a click listener from the child adapter on Activity, and also after the click on the item, I want to remove the whole recycler view. Just like a chatbot in Swiggy.
Have a method in DeepLinkAdapter that clears the whole list:
public class DeepLinkAdapter extends RecyclerView.Adapter<DeepLinkAdapter.DeepLinkViewHolder> {
.......
public void clearTheWholeList(){
dataItemList.clear();
notifyDataSetChanged();
}
}
Have a method in your MessageListAdapter that removes an item completely:
public class MessageListAdapter extends RecyclerView.Adapter {
......
......
private int positionToClear = -1;
public void removeItem(int position){
positionToClear = position;
notifyDataSetChanged();
}
//in onBindViewHolder
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
............
............
//pass the positionToClear here
((ReceivedMessageHolder) holder).bindRv(chatMessage, mContext, recycledViewPool, onItemClickListener , positionToClear);
}
.......
}
In ReceivedMessageHolder
private class ReceivedMessageHolder extends RecyclerView.ViewHolder {
//here add new param for removed position
void bindRv(Payload chatMessage, Context context, RecyclerView.RecycledViewPool recycledViewPool, OnItemClickListener onItemClickListener, int positionToClear) {
if (chatMessage.getData() != null && !chatMessage.isOptionSelected()) {
DeepLinkAdapter deepLinkAdapter = new DeepLinkAdapter(context, chatMessage.getData(), onItemClickListener, getAdapterPosition());
//do a check here
if(getAdapterPosition() == positionToClear){
deepLinkAdapter.clearTheWholeList();
}
.......
.......
.......
} else {
rvDeepLink.setVisibility(View.GONE);
}
}
}
Assuming the onItemClick interface is working:
#Override
public void onItemClick(int childPos, int parentPos) {
...........
...........
//somewhere where you want the item to be removed
messageListAdapter.removeItem(parentPos);
............
............
}

In onBindViewHolder method I call another adapter inside this adapter which follows the same OnClickListener structure :
public class PokemonFavoritesAdapter extends RecyclerView.Adapter<PokemonFavoritesAdapter.ViewHolder> {
private Context mContext;
private List<Pokemon> favoritePokemon;
private LayoutInflater mInflater;
private PokemonFavoritesAdapter.ItemClickListener mClickListener;
public PokemonFavoritesAdapter(Context context, List<Pokemon> list) {
this.mInflater = LayoutInflater.from(context);
mContext = context;
favoritePokemon = list;
}
#NonNull
#Override
public PokemonFavoritesAdapter.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = mInflater.inflate(R.layout.list_item_pokemon_favorite, parent, false);
return new PokemonFavoritesAdapter.ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull PokemonFavoritesAdapter.ViewHolder holder, int position) {
Pokemon pokemon = favoritePokemon.get(position);
String pokemonId = pokemon.get_id();
int dominantColor = PokemonUtils.getDominantColorFromPokemon(pokemonId, mContext);
int lighterDominantColor = PokemonUtils.lighterColor(dominantColor, GenericConstants.DARK_FACTOR);
int pokemonImageId = PokemonUtils.getPokemonSugimoriImageById(pokemonId, mContext);
holder.circularImageView.setBorderColor(dominantColor);
holder.circularImageView.setBorderWidth(4);
holder.circularImageView.setCircleColor(lighterDominantColor);
holder.circularImageView.setShadowRadius(6);
Picasso.get().load(pokemonImageId).fit().into(holder.circularImageView);
}
#Override
public long getItemId(int position) {
return position;
}
#Override

int size = 0;
if (Objects.nonNull(favoritePokemon) && !favoritePokemon.isEmpty()) {
size = favoritePokemon.size();
}
return size;
}
// convenience method for getting data at click position
public Pokemon getItem(int id) {
return favoritePokemon.get(id);
}
// allows clicks events to be caught
public void setClickListener(PokemonFavoritesAdapter.ItemClickListener itemClickListener) {
this.mClickListener = itemClickListener;
}
// parent activity will implement this method to respond to click events
public interface ItemClickListener {
void onItemClick(View view, int position);
}
// stores and recycles views as they are scrolled off screen
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
CircularImageView circularImageView;
ViewHolder(View view) {
super(view);
circularImageView = view.findViewById(R.id.civ_pokemon_favorite);
view.setOnClickListener(this);
}
#Override
public void onClick(View view) {
if (mClickListener != null) {
mClickListener.onItemClick(view, getAdapterPosition());
}
}
}
}
However I have a problem , my activity can't listen the click events that happens inside my nested adapter :
public class PokemonTeambuilderActivity extends AppCompatActivity implements TeambuilderAdapter.ItemClickListener {
#Override
public void onItemClick(View view, int position) {
}
I don't know how to reach the events that happens within my PokemonFavoritesAdapter in my TeambuilderAdapter , I supose that I must implement the PokemonFavoritesAdapter.OnClickListener interface in my TeambuilderAdapter but I don't know how to do it . Any hint ?
I need send ArrayList list_add to activity but I don't know how I can do it if is possible share it on main activity for use it in the future.
Anyone can help me to implement a method for do it?
below have MainAdatper for recyclerview where I have a list_add and want passed it to main activity and after I can add it to
class MainAdapter extends RecyclerView.Adapter <MainAdapter.ViewHolder> {
private static int lastCheckedPos = 0;
ArrayList<String> list_add = new ArrayList<>();
ArrayList<String> lista_show;
private Context context;
String t;
public MainAdapter(ArrayList<String> lista_shows, Context context) {
lista_show = lista_shows;
}
#Override
public MainAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from (parent.getContext ()).inflate (R.layout.row,parent,false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(final MainAdapter.ViewHolder holder, final int position) {
holder.mdevice.setText (lista_show.get (position));
holder.cardView.setOnLongClickListener (new View.OnLongClickListener () {
#Override
public boolean onLongClick(View v) {
t = lista_show.get(position);
if (list_add.contains(t)) {
Toast.makeText(v.getContext (), t+"Already Selected", Toast.LENGTH_SHORT).show();
} else {
list_add.add(t);
holder.cardView.setCardBackgroundColor(Color.parseColor("#60B5EC"));
Toast.makeText(v.getContext (), t+"Added", Toast.LENGTH_SHORT).show();
}
return true;
}
});
holder.cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
t = lista_show.get (position);
holder.cardView.setCardBackgroundColor(Color.WHITE);
if (! list_add.contains(t)) {
Toast.makeText(v.getContext (), "Long press for add", Toast.LENGTH_SHORT).show();
} else {
list_add.remove(t);
Toast.makeText(v.getContext (), t+"Removed", Toast.LENGTH_SHORT).show();
}
}
});
}
#Override
public int getItemCount() {
return lista_show.size ();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView mdevice;
CardView cardView;
public ViewHolder( View itemView) {
super (itemView);
mdevice = itemView.findViewById (R.id.device);
cardView = itemView.findViewById (R.id.mcardview);
}
}
}
Add interface for callback:
public interface ListOwner {
void push(ArrayList<String> list);
}
Set refernce in adapter:
private ListOwner listOwner;
public MainAdapter(ArrayList<String> lista_shows, Context context, ListOwner owner) {
this.lista_show = lista_shows;
this.listOwner = owner;
}
The call it in adapter when you need:
if (listOwner != null) {
listOwner.push(list_add);
}
Of course, implement ListOwner by your activity:
public class MyActivity extends AppCompatActivity implements ListOwner {
// all code
// create instance of adapter:
mAdapter = new MainAdapter(list_show, MyActivity.this, MyActivity.this);
#Override
public void push(ArrayList<String> list) {
// you have the list here
}
}
P.S.
You can omit interface and pass reference to the Activity directly (MyActivity in the sample)
By overwriting getItemPosition() method I can refresh my FragmentStatePagerAdapter, which works fine. But the change of the contents is not nice to see.
Is there possibility to apply any kind of animation as I refresh the FragmentStatePagerAdapter?
I was also facing same issue.So, what should you do. Make global variables in your adapter for what you want continuous animate.
Now when you start animation on button click. Pass value to global variables.
When you notifydatasetchanged it doesn't effect your animation.
I haven't found any correct way. So, did this thing.It's working perfect.

I develop a fragment using Horizontal RecyclerView in a Vertical RecyclerView (like Google Play Store).
When i notifyDataSetChanged from the parent RecyclerView, the child RecyclerView lose the position because the setAdapter is call in the onBindViewHolder I think. Also when i scroll to the 5th position in the first horizontal recyclerview if i scroll down and come back up i loose the 5th position.
I try to use RecyclerView.scrollToPosition() but that don't work.
So i think i have two solution :
a way (by a method or setting) to keep the position of my child recycler view. (BEST SOLUTION)
a way to set manually the recyclerview position to where it was before the refresh. (ELSE SOLUTION)

If someone has a solution for me
Thank you
Store x scroll offset in a SparseArray for position and restore when bind view holder.
public class ProfilesCardViewListAdapter extends RecyclerView.Adapter<ProfilesCardViewListAdapter.ItemRowHolder> {
private SparseIntArray sparseArray = new SparseIntArray();
#Override
public void onBindViewHolder(final ItemRowHolder holder, final int position) {
// Use srollBy for animate scrolling
holder.itemRecyclerView.srollBy(sparseArray.get(position, 0), 0);
// Or scrollTo for restore previous x offset
//holder.itemRecyclerView.srollTo(sparseArray.get(position, 0), 0);
holder.itemRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
sparseArray.put(position, dx);
}
}
}
}
I found a solution, i use the onTouchListener in the child recyclerView to set a scrollPosition (i don't use onScrollListener because this method is deprecated) i implement a getter to this field to get the scroll position from the parent RecyclerView and so at the end of the onBindViewHolder in the parent RecyclerView i call (child)RecyclerView.scrollToPosition(scrollPosition).
And that's make the job

I have it clicked and it gets up to it and shows the right getText() method but the setText method is not working...
userAdapter.setOnEntryClickListener(new UserAdapter.OnEntryClickListener() {
#Override
public void onEntryClick(View view, int position) {
DatabaseUser user = dbUsersList.get(position);
TextView clickedView = (TextView) view.findViewById(R.id.userAdapterFollowBtn);
if(view == clickedView) {
if (clickedView.getText().equals("following")) {
Log.d(Constants.DEBUG, " THE CLICK VIEW IS " + clickedView.getText());
//APPLY Following
String txtFollow = "follow";
clickedView.setText(txtFollow);
if (user.getIsChanged() == 0) {
user.setIsChanged(1);
} else {
user.setIsChanged(0);
}
user.setIsType(3);
db.updateFollow(user);
userAdapter.notifyDataSetChanged();
} else {
clickedView.setText("following");
if (user.getIsChanged() == 0) {
user.setIsChanged(1);
} else {
user.setIsChanged(0);
}
user.setIsType(0);
db.updateFollow(user);
userAdapter.notifyDataSetChanged();
}
} else {
Toast.makeText(getApplicationContext(), user.getUsername() + " is selected!", Toast.LENGTH_SHORT).show();
takeToUserProfile(dbUsersList.get(position));
}
}
});

private Typeface typeFace, italicTypeface, boldTypeface;

final int pos = getItemViewType(position);
//TODO Create pic link
if(containsId(dbUsersList.get(pos), followingList)) {
//Then show following
holder.userAdapterFollowBtn.setText("following");
} else {
//show follow
holder.userAdapterFollowBtn.setText("follow");

}
}
#Override
public int getItemCount() {
return dbUsersList.size();
}
public static boolean containsId(DatabaseUser currentUser, List<DatabaseUser> list) {
for (DatabaseUser object : list) {

I have done the same in this project, go here and copy this itemclicklistener class:
https://github.com/isaacurbina/MyMovies/blob/c985f28311f25522c7907d090e48dab5fc108c01/app/src/main/java/com/mobileappsco/training/mymovies/Listeners/RecyclerItemClickListener.java
Then on your Activity or Fragment do this with your recyclerview object.
recyclerView.addOnItemTouchListener(
new RecyclerItemClickListener(context, new RecyclerItemClickListener.OnItemClickListener() {
#Override
public void onItemClick(View view, int position) {
// HERE GOES YOUR CODE FOR THE CLICK OF THE ITEM
}
})
);
Then you can use the position to reference the original object inside the list of objects that your adapter is using (the list should be public so that you can access it from the Activity or Fragment), or do like me and put a hidden textview with the ID instead of the position that you can get with:
TextView clickedItem = (TextView) view.findViewById(R.id.hidden_id_textview);
int id = clickedItem.getText();
You can also check at the whole project that contains the class that I sent you in the link above. I hope it helps.
Kind regards!
