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

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

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

Try adding this:
//Check if current item have description
if (workDayItemList.get(position).getDesc().length() > 2) {
Log.i(TAG, "TESTER: desc dote added");
holder.doteOfDesc.setVisibility(View.VISIBLE);
}
else if( workDayItemList.get(position).getDesc().length() < 2
&& holder.doteOfDesc.getVisibility()== View.VISIBLE ){
holder.doteOfDesc.setVisibility(View.GONE);
}
The reason why this is happening is that RecyclerView creates as many ViewHolders as its needed to cover a whole screen plus few extra ( 12 in your case) then reuses them via rebinding values to views. And you set doteOfDescto View.VISIBLE in 2. ViewHolder, but never set it back to View.GONE, thats why every time that ViewHolder is reused it will have doteOfDesc visible.
The Prettier version:
Boolean hasDescription = workDayItemList.get(position).getDesc().length() > 2;
holder.doteOfDesc.setVisibility( hasDescription ? View.VISIBLE : View.GONE);

Issue with RecyclerView data interchanges while scrolling

There is Scroll by loading RecyclerView(Lazy loading). When an item quantity is incremented by adding the plus button to say 10. after loading the next set of items while scrolling, The item quantity(10) is reset to 1 and 10 will be displayed for another item.
In the same sequence, if the unit is changed(by the spinner) to another unit the corresponding image will be loaded but after scrolling the unit and image will change back to initial unit.
When the image of an item is clicked, a dialog will show the details of the selected item . Sometimes the image in the dialog is correct but image of the RecyclerView is incorrect, will take time to load or will not load.

Holder cardview change textview color error

i want to change color of my textview inside of cardview when its value is "kritis" or "kurang" but somehow everytime when my textview in position 0 and its value is either kritis or kurang it always change color textiew in position 0 and also position 7, and also when its in position 1 it will set color text view in position 8 too and so... and then i try to use logd to see howmany times my setcolor initiate and its only 1x (when changing color only position 1 and 7) or 2x (when changing color text position 0,1,7,8)(my cardview is inside recyclerview)
this is my adapter code
public class ListAdapter extends RecyclerView.Adapter<form_mhs_04_fragment2.ListAdapter.ViewHolder>

this is how i send data to adapter
public void initListView(String UserId){

ipk_cap = new String[list.size()];
ipk_kat = new String[list.size()];
sks_cap = new String[list.size()];
sks_kat = new String[list.size()];

ipk_kat[i] = list.get(i).getKategoriIpk();

Log.e("debug", "onFailure: ERROR > " + t.toString());
Intent intent = new Intent(getActivity().getBaseContext(), Form_Mhs_Menu.class);

}
and this is my Datanote
package com.example.bimbinganpasi.Form_04.adapter;
public class DataNote {

}
public String getSkscap() {
return skscap;
}
public String getCatatan() {
return catatan;
}
public String getSemester() {

}
}

try adding else to set default background color :
if(holder.textViewSKSkat.getText().equals("kritis") || holder.textViewSKSkat.getText().equals("kurang")){
holder.textViewSKSkat.setTextColor(Color.rgb(255,0,0));
Log.d("testing", "ayayaya");
} else {
holder.textViewSKSkat.setTextColor(Color.rgb(0,0,0)); //TODO : SET DEFAULT COLOR
}
if(holder.textViewIPKkat.getText().equals("kritis") || holder.textViewIPKkat.getText().equals("kurang")){
holder.textViewIPKkat.setTextColor(Color.rgb(255,0,0));
Log.d("testing", "ayayaya");
} else {
holder.textViewIPKkat.setTextColor(Color.rgb(0,0,0)); //TODO : SET DEFAULT COLOR
}

In My Case i tried this code..
holder.textview.setColor(ContextCompat.getColor(YourActivity.this,R.color.colorPrimary));

Java: How to make own total number counter for every RecyclerView item?

I need to make a total number counter for every RecyclerView item individually. Here are a picture and code to clear this situation out:
TTL is that total counter that I need. When I click player 1 plus symbol, total counter in that particular item should be increased by 1 and minus symbol decrease by 1.
What I have at the moment:
ViewHolder (handle minus and plus symbols):
public static class GameViewHolder extends RecyclerView.ViewHolder {
public TextView mTextPlayer, mTextPar, mTotalTxt, mNumberTotal;
public ImageView mImageMinus, mImagePlus;
public GameViewHolder(#NonNull View itemView, final GameAdapter.OnItemClickListener listener) {
super(itemView);
mTextPlayer = itemView.findViewById(R.id.gameNameRecycler);
mTextPar = itemView.findViewById(R.id.gameParNumberRecycler);
mImageMinus = itemView.findViewById(R.id.game_minus_btn);
mImagePlus = itemView.findViewById(R.id.game_plus_btn);
mTotalTxt = itemView.findViewById(R.id.game_total_txt);
mNumberTotal = itemView.findViewById(R.id.game_total_number);
mImageMinus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (listener != null) {
int position = getAdapterPosition();
if (position != RecyclerView.NO_POSITION) {
listener.onMinusClick(position);
}
}
}
});
mImagePlus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (listener != null) {
int position = getAdapterPosition();
if (position != RecyclerView.NO_POSITION) {
listener.onPlusClick(position);
}
}
}
});
}
}
In Activity:
mAdapter.setOnItemClickListener(new GameAdapter.OnItemClickListener() {
int totalCounter = 0;
#Override
public void onMinusClick(int position) {
String parNum = mGameItemList.get(position).getText2();
int intParNm = Integer.valueOf(parNum);
if (intParNm != 1) {
intParNm -= 1;
totalCounter -= 1;
mGameItemList.get(position).changeText2(Integer.toString(intParNm));
mGameItemList.get(position).changeText4(Integer.toString(totalCounter));
mAdapter.notifyDataSetChanged();
}
}
#Override
public void onPlusClick(int position) {
String parNum = mGameItemList.get(position).getText2();
int intParNm = Integer.valueOf(parNum);
if (intParNm != 99) {
intParNm += 1;
totalCounter += 1;
mGameItemList.get(position).changeText2(Integer.toString(intParNm));
mGameItemList.get(position).changeText4(Integer.toString(totalCounter));
mAdapter.notifyDataSetChanged();
}
}
});
So this is what I have now, but atm every item uses that same itemCounter, so if I click player 1 plus button, its TTL is 1 (as it should) but after that when I click player 2 plus button, player 2 TTL should be also 1 but is in fact 2, cause that 1 extra came from that player 1 plus click.
How I can change this to work for both individually?

On thing is you can call notifyItemChanged(position), on the position of the row that has changed, it will only update that item in the recycler view.
Instead of holding your count in totalCounter, you could get the value from the viewholder that is already assigned, so something like String totalCounter = ((TextView) recyclerView.findViewHolderForAdapterPosition(position).itemView.findViewById(R.id.view)).getText().toString();
#Override
public void onMinusClick(int position) {
String parNum = mGameItemList.get(position).getText2();
int intParNm = Integer.valueOf(parNum);
if (intParNm != 1) {
intParNm -= 1;
totalCounter -= 1;
mGameItemList.get(position).changeText2(Integer.toString(intParNm));
mGameItemList.get(position).changeText4(Integer.toString(totalCounter));
adapter.notifyItemChanged(position);
}
}

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;
}
