Stop recyclerview from trying to update when "Favourite" button is clicked

I have a "favourite" button for each row of my recyclerview which the user clicks when the like the image (obviously). Each row is a cardview that I only want to "flip" when the user opens the fragment.
When the user clicks the button I update my database with "Y" or "N".
My problem is that my recyclerview refreshes even though the list hasn't changed. When it refreshes all my cards flip which I do not want. How can I stop the recyclerview from updating when the button is clicked?
Here is my adapter class
#Override
public void onBindViewHolder(#NotNull final ClothesViewHolder holder, final int position) {
String image;
if (flip) {
holder.flipView.flipTheView();
}
ClothingItem current = mClothingItems.get(position);
holder.itemNameView.setText(current.getItem());
holder.categoryNameView.setText(current.getCategory());
holder.seasonNameView.setText(current.getSeason());
Integer yesCount = current.getYesCount();
Integer noCount = current.getNoCount();
if (current.getFavourite().equalsIgnoreCase("N")) {
holder.animationView.setProgress(0);
}
else {
holder.animationView.setProgress(1);
}
holder.yesTextView.setText(String.valueOf(yesCount));
holder.noTextView.setText(String.valueOf(noCount));
image = current.getPhotoPath();
Glide.with(holder.cardView)
.load(image)
.into(holder.pictureView);
flip = false;
} catch (NullPointerException e) {
Log.e("Picture","onBindViweHolder: Null Point:" + e.getMessage());
}
holder.animationView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
listener.onFavouriteClick(position);
}
});
public interface clickButtons {
void onFavouriteClick(int position);
}
Fragment Class
#Override
public void onFavouriteClick(int position) {
RecyclerView.ViewHolder holder = recyclerView.findViewHolderForAdapterPosition(position);
LottieAnimationView animationView = holder.itemView.findViewById(R.id.favouriteAnimation);
ClothingItem item = springList.get(position);
final Long id = item.getId();
if (animationView.getProgress() > 0) {
animationView.setProgress(0);
mClothingViewModel.updateFavourite(id.intValue(), "N");
adapter.notifyItemChanged(position,"favourite");
} else if (animationView.getProgress() == 0) {
animationView.playAnimation();
mClothingViewModel.updateFavourite(id.intValue(),"Y");
}
}
I tried to use onBindViewHolder with payloads but I get the same result. I think I'm not calling this properly
adapter.notifyItemChanged(position,"favourite");
Adapter class
#Override
public void onBindViewHolder(final ClothesViewHolder holder ,final int position, final List<Object> payloads){
String image;
if(!payloads.isEmpty()) {
ClothingItem current = mClothingItems.get(position);
holder.itemNameView.setText(current.getItem());
holder.categoryNameView.setText(current.getCategory());
holder.seasonNameView.setText(current.getSeason());
Integer yesCount = current.getYesCount();
Integer noCount = current.getNoCount();
if(yesCount == null) {
yesCount = 0;
}
if (noCount == null) {
noCount = 0;
}
if (current.getFavourite() == null || current.getFavourite().equalsIgnoreCase("N")) {
holder.animationView.setProgress(0);
}
else {
holder.animationView.setProgress(1);
}
// Log.d("Counting","Yes count " + yesCount + " no count " + noCount);
holder.yesTextView.setText(String.valueOf(yesCount));
holder.noTextView.setText(String.valueOf(noCount));
image = current.getPhotoPath();
Glide.with(holder.cardView)
.load(image)
.into(holder.pictureView);
} else {
onBindViewHolder(holder,position);
}
}
Fragment
#Override
public void onFavouriteClick(int position) {
RecyclerView.ViewHolder holder = recyclerView.findViewHolderForAdapterPosition(position);
LottieAnimationView animationView = holder.itemView.findViewById(R.id.favouriteAnimation);
ClothingItem item = springList.get(position);
final Long id = item.getId();
if (animationView.getProgress() > 0) {
animationView.setProgress(0);
mClothingViewModel.updateFavourite(id.intValue(), "N");
adapter.notifyItemChanged(position,"favourite");
} else if (animationView.getProgress() == 0) {
animationView.playAnimation();
mClothingViewModel.updateFavourite(id.intValue(),"Y");
adapter.notifyItemChanged(position,"favourite");
}
}

Recyclerview is updated or refreshed when notifiydataSetChanged is called.
try to remove notifiyDataSetChanged in the click event maybe

How to Delete Item Without Deleting Position in Recycler View?

I really need your help. I've searched Google many days with many keywords, but I couldn't get it. So, I decided to ask to you.
So, here it is. Actually, I have one button in RecyclerView, but this button is repeated as much amount of data available, there are: Button with text "Baca 3x", "Baca 4x", and so on. I want, if I click button with text "Baca 3x" 3 times, it will change to "Baca 2x" >> "Baca 1x" >> remove item. Also if I click button with text "Baca 4x" 4 times, it will change to "Baca 3x" >> "Baca 2x" >> "Baca 1x" >> remove item.
But my problem is, I can't treat every button with different treatment, because every time the item has been deleted, position of data changes automatically. Because of this, I can't get specific button. For example: There is two button,
1. Button "Baca 3x" on position 0
2. Button "Baca 4x" on position 1
If button "Baca 3x" on position 0 has been deleted, so button "Baca 4x" changed it's position automatically to 0. The problem lays here.
Until now I just get every button based on their positions, which is a problem for me. Because of this I am thinking about How to Delete Item Without Deleting Position in Recycler View? Can you guys solve my problem? Should I use DiffUtil?And how to use it? Below the complete code I use:

UPDATE (FIX CODE) By: Krishna Sharma:
https://github.com/seadclark/RecyclerViewWithButtonClicks

Here is the fix. just update the ModelDoa constructor as below. I have verified myself and working as expected now. Also sent you pull request on github.
public ModelDoa(String name, String butong, int type) {
this.mName = name;
this.bName = butong;
this.mType = type;
String[] data = butong.split("\\s");
if (data.length > 0) {
String count = data[1].substring(0, data[1].length() - 1);
read10 = Integer.parseInt(count);
}
}

Instead of removing the item from your list AND updating the interface, have two methods. One of them (deleteItem) will only delete the item and the other (deleteItemAndUpdate) will delete the item and update the interface.
public void deleteItem(int position) {
mList.remove(position); // hapus list
}
public void deleteItemAndUpdate(int position) {
mList.remove(position); // hapus list
notifyItemRemoved(position); // hapus tampilan
}
In the future, you can decide whether you want to only remove the item from your list OR remove the item and update the UI.
EDIT 1:
You need to keep track of the amount of times that each item was clicked. We can call this value readCount. Every time that the item is clicked, we subtract 1 from this value. When this value reaches 0, we remove it from the list.
ModelDoa:
public class ModelDoa {
private int readCount = 10;
public int getReadCount() {
return this.readCount;
}
public void setReadCount(int readCount) {
this.readCount = readCount;
}
}
PagiViewHolder:
private View.OnClickListener bacaClickListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
teksbaca = (Button) v.findViewById(R.id.buttonbaca);
ModelDoa modelDoa = mAdapter.getItem(getAdapterPosition());
if (modelDoa != null) {
modelDoa.setReadCount(modelDoa.getReadCount() - 1);
if (modelDoa.getReadCount() <= 0) {
myAdapter.deleteItem(getAdapterPosition());
}
teksbaca.setText("Baca " + modelDoa.getReadCount() + "x");
}
}
};
AdapterDoa:
public ModelDoa getItem(int position) {
if (position > -1 && position < getItemCount()) {
return this.mList.get(position);
} else {
return null;
}
}
EDIT 2:
The idea is to set the readCount variable when you instantiate the object. You do not have multiple variables that do the same thing. You just change the single readCount variable to be either 7 or 10 when you are creating it and use the same getItem method when retrieving the model (not variable!) itself.
ModelDoa:
public class ModelDoa {
private String name;
private String butong;
private int type;
private int readCount;
public ModelDoa(String name, String butong, int type, int readCount) {
this.mName = name;
this.bName = butong;
this.mType = type;
this.readCount = readCount;
}
public int getReadCount() {
return this.readCount;
}
public void setReadCount(int readCount) {
this.readCount = readCount;
}
}
DoaPagi:
private List<ModelDoa> getData() {
String[] data = getResources().getStringArray(R.array.doapagi);
String[] baca = getResources().getStringArray(R.array.bacapagi);
List<ModelDoa> list = new ArrayList<ModelDoa>();
for (int i = 0; i < data.length; i++) {
// Here is where you would set the value of readCount.
list.add(new ModelDoa(data[i], baca[i], ModelDoa.DOA_PAGI, i));
}
return list;
}

Pagination with staggeredGridLayoutManager and recyclerView

Hello I need to make the infinite scrolling (Pagination) with the recyclerview using the staggeredGridLayoutManager. Pagination is working but the problem is that onLoadMore() function is called so many times while scrolling which causing problems, here is my code:
newSearchAdapter = new NewSearchAdapter(getActivity(), gridData);
StaggeredGridLayoutManager mLayoutManager;
mLayoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);
mLayoutManager.setGapStrategy(StaggeredGridLayoutManager.GAP_HANDLING_NONE);
rv_NewProfilesGrid.setLayoutManager(mLayoutManager);
rv_NewProfilesGrid.setAdapter(newSearchAdapter);
rv_NewProfilesGrid.addOnScrollListener(new EndlessRecyclerOnScrollListenerStaggeredLayoutmanager(mLayoutManager) {
#Override
public void onLoadMore(int current_page) {
//calling the api
}
});
and here is my scroll listner
I think the problem here is with the getFirstVisibleItems() function because with GridLayoutManger or LinearLayoutManager it returns an integer but with StaggeredLayout it returns an int Array, so I did the following:
public abstract class EndlessRecyclerOnScrollListenerStaggeredLayoutmanager extends RecyclerView.OnScrollListener {
public static String TAG = EndlessRecyclerOnScrollListenerStaggeredLayoutmanager.class.getSimpleName();
private int scrolledDistance = 0;
private boolean controlsVisible = false;
private boolean loading = true; // True if we are still waiting for the last set of data to load.
private int visibleThreshold = 5; // The minimum amount of items to have below your current scroll position before loading more.
public static boolean loadOneTime = false;
private int pastVisibleItems, visibleItemCount, totalItemCount,previousTotal;
private int current_page = 1;
private StaggeredGridLayoutManager mStaggeredGridLayoutManager;
public EndlessRecyclerOnScrollListenerStaggeredLayoutmanager(StaggeredGridLayoutManager staggeredGridLayoutManager) {
this.mStaggeredGridLayoutManager = staggeredGridLayoutManager;
}
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
visibleItemCount = recyclerView.getChildCount();
totalItemCount = mStaggeredGridLayoutManager.getItemCount();
int[] firstVisibleItems = null;
firstVisibleItems = mStaggeredGridLayoutManager.findFirstVisibleItemPositions(firstVisibleItems);
if (firstVisibleItems != null && firstVisibleItems.length > 0) {
pastVisibleItems = firstVisibleItems[0];
}
if (loading) {
if ((visibleItemCount + pastVisibleItems) >= totalItemCount) {
loading = false;
previousTotal = totalItemCount;
}
}
if (!loading && (totalItemCount - visibleItemCount)
<= (pastVisibleItems + visibleThreshold)) {
// End has been reached
// Do something
current_page++;
loadOneTime=false;
onLoadMore(current_page);
loading = true;
}
if (scrolledDistance > 1 && controlsVisible) {
controlsVisible = false;
scrolledDistance = 0;
} else if (scrolledDistance < -1 && !controlsVisible) {
controlsVisible = true;
scrolledDistance = 0;
}
if ((controlsVisible && dy > 0) || (!controlsVisible && dy < 0)) {
scrolledDistance += dy;
}
}
public abstract void onLoadMore(int current_page);
}

Try this. I borrowed it from a stack overflow answer and borrowed another answer and combine to of them I finally solve it.
import android.util.Log
import androidx.recyclerview.widget.GridLayoutManager
import androidx.recyclerview.widget.LinearLayoutManager
import androidx.recyclerview.widget.RecyclerView
import androidx.recyclerview.widget.StaggeredGridLayoutManager
abstract class PaginationScrollListener constructor() :
RecyclerView.OnScrollListener() {
private lateinit var mLayoutManager: RecyclerView.LayoutManager
constructor(layoutManager: GridLayoutManager) : this() {
this.mLayoutManager = layoutManager
}
constructor(layoutManager: StaggeredGridLayoutManager) : this() {
this.mLayoutManager = layoutManager
}
constructor(layoutManager: LinearLayoutManager) : this() {
this.mLayoutManager = layoutManager
}
/*
Method gets callback when user scroll the search list
*/
override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
super.onScrolled(recyclerView, dx, dy)
val visibleItemCount = mLayoutManager.childCount
val totalItemCount = mLayoutManager.itemCount
var firstVisibleItemPosition = 0
when (mLayoutManager) {
is StaggeredGridLayoutManager -> {
val firstVisibleItemPositions =
(mLayoutManager as StaggeredGridLayoutManager).findFirstVisibleItemPositions(null)
// get maximum element within the list
firstVisibleItemPosition = firstVisibleItemPositions[0]
}
is GridLayoutManager -> {
firstVisibleItemPosition =
(mLayoutManager as GridLayoutManager).findFirstVisibleItemPosition()
}
is LinearLayoutManager -> {
firstVisibleItemPosition =
(mLayoutManager as LinearLayoutManager).findFirstVisibleItemPosition()
}
}
if (!isLoading && !isLastPage) {
if (visibleItemCount + firstVisibleItemPosition >= totalItemCount
&& firstVisibleItemPosition >= 0
) {
Log.i(TAG, "Loading more items")
loadMoreItems()
}
}
}
protected abstract fun loadMoreItems()
abstract val isLastPage: Boolean
abstract val isLoading: Boolean
companion object {
private val TAG = PaginationScrollListener::class.java.simpleName
}
}
And use this in your recycler view in this way
rvCategoryProducts.addOnScrollListener(object :
PaginationScrollListener(layoutManager) {
override fun loadMoreItems() {
vm.isLoading = true
vm.currentPage++
GlobalScope.launch {
vm.getCategoryProductByCatId(vm.id, vm.currentPage)
}
}
override val isLastPage: Boolean
get() = vm.isLastPage
override val isLoading: Boolean
get() = vm.isLoading
})

Loading message not hiding in Recyclerview android

I am using endless Recyclerview which is loading data from Parse.com database.The problem I am facing is that it is displaying two loading images like shown in below screen.I want to display one item at time and then on scrolling show the icon then load the next item.
Code for EndlessScroll is -
public abstract class EndlessScroll extends RecyclerView.OnScrollListener {
public static String TAG = EndlessScroll.class.getSimpleName();
private int previousTotal = 0; // The total number of items in the dataset after the last load
private boolean loading = true; // True if we are still waiting for the last set of data to load.
private int visibleThreshold = 2; // The minimum amount of items to have below your current scroll position before loading more.
int firstVisibleItem, visibleItemCount, totalItemCount;
Context context;
private int current_page = 1;
private LinearLayoutManager mLinearLayoutManager;
public EndlessScroll(LinearLayoutManager linearLayoutManager, Context context) {
this.mLinearLayoutManager = linearLayoutManager;
this.context = context;
}
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
visibleItemCount = recyclerView.getChildCount();
totalItemCount = mLinearLayoutManager.getItemCount();
firstVisibleItem = mLinearLayoutManager.findFirstVisibleItemPosition();
if (loading) {
if (totalItemCount > previousTotal) {
loading = false;
previousTotal = totalItemCount;
}
}
if (!loading && (totalItemCount - visibleItemCount)
<= (firstVisibleItem + visibleThreshold)) {
// End has been reached
// Do something
current_page++;
onLoadMore(current_page);
loading = true;
}
}
public abstract void onLoadMore(int current_page);
}
I have started working in android of late.
I am not sure why the loading behaviour is problematic.
Your help/suggestion/any pointer is much appreciated.

To Show only 10 item first time in ListView and show more items on scroll follow following steps:
STEP 1: Create a chunkList method which divide ArrayList in parts of size 10:
static <T> List<ArrayList<T>> chunkList(List<T> list, final int L) {
List<ArrayList<T>> parts = new ArrayList<ArrayList<T>>();
final int N = list.size();
for (int i = 0; i < N; i += L) {
parts.add(new ArrayList<T>(
list.subList(i, Math.min(N, i + L)))
);
}
return parts;
}
STEP 2: Create ArrayList and a counter which show current part :
private boolean isLoadingMore=false;
Handler mHandler = new Handler();
List<ArrayList<HashMap<String,String>>> mainArrayList;
private int count=0;
STEP 3: In onPostExecute break result and show data in ListView:
protected void onPostExecute(ArrayList<HashMap<String,String>> result) {
super.onPostExecute(result);
// your code here...
mainArrayList=chunkList(result,10);
isLoadingMore=false;
count=0;
adapter = new CustomAdapterSent(Interestsent.this,
mainArrayList.get(count));
setListAdapter(adapter);
}
}
STEP 4: Create addAll method in Adapter to append data in current data source :
public void addAll(ArrayList<HashMap<String,String>> moreData){
this.listData.addAll(moreData);
this.notifyDataSetChanged();
}
STEP 5: In onLoadMore load more data in ListView:
mHandler = new Handler();
listview.setOnScrollListener(new EndlessScrollListener() {
#Override
public void onLoadMore(int page, int totalItemsCount) {
if(count<mainArrayList.size()-1)
{
if(adapter !=null){
count++;
if(!isLoadingMore){
isLoadingMore=true;
mHandler.postDelayed(loadMoreRunnable,1000);
}
}
}
}
});
}
Runnable loadMoreRunnable = new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
if(count<mainArrayList.size())
{
if(adapter !=null){
count++;
adapter.addAll(mainArrayList.get(count));
mHandler.removeCallbacks(loadMoreRunnable);
isLoadingMore=false;
}
}
}
};

To have an AdapterView (such as a ListView or GridView) that automatically loads more items as the user scrolls through the items (aka infinite scroll). This is done by triggering a request for more data once the user crosses a threshold of remaining items before they've hit the end. Every AdapterView has support for binding to the OnScrollListener events which are triggered whenever a user scrolls through the collection. Using this system, we can define a basic EndlessScrollListener which supports most use cases by creating our own class that extends OnScrollListener.
