How to fix my onClick cardView that is returning other figures

I have a recycler that is showing a list of items, there price and status. When I click on a card, I want it to show the price of the item that I have clicked on. However whenever, I click. The card returns the data of other cards and no the particular card that I have clicked.
public class ItemAdapter extends RecyclerView.Adapter<ItemAdapter.ItemHolder> {
private TextView viewName, viewPrice;
private CheckBox viewAvailability;
private Context context;
private List<Item> listItems;
#NonNull
#Override
public ItemAdapter.ItemHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
return new ItemAdapter.ItemHolder(view);
}
#Override
public void onBindViewHolder(#NonNull ItemAdapter.ItemHolder holder, int position) {
Item item = listItems.get(position);
holder.setDetails(item);
}
#Override
public int getItemCount() {
return listItems.size();
}
public class ItemHolder extends RecyclerView.ViewHolder {
public ItemHolder(final View itemView) {
super(itemView);
viewName = itemView.findViewById(R.id.viewName);
viewPrice = itemView.findViewById(R.id.viewPrice);
viewAvailability = itemView.findViewById(R.id.viewAvailability);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
}
public void setDetails(Item item) {
viewName.setText(item.getName());
viewPrice.setText(item.getPrice());
int as = item.getAvailabilityStatus();
if (as == 1) {
viewAvailability.setChecked(true);
} else {
}
}
}
public ItemAdapter(Context context, List<Item> objects) {
this.context = context;
this.listItems = objects;
}
}

Try this code,put itemView onclick listner inside setDetails
public void setDetails(Item item) {
viewName.setText(item.getName());
viewPrice.setText(item.getPrice());
int as = item.getAvailabilityStatus();
if (as == 1) {
viewAvailability.setChecked(true);
} else {
}
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// here you will able to access valid item
}
});
}

Try this code...
public class ItemAdapter extends RecyclerView.Adapter<ItemAdapter.ItemHolder> {
private Context context;
private List<Item> listItems;
#NonNull
#Override
public ItemAdapter.ItemHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
return new ItemHolder(view);
}
#Override
public void onBindViewHolder(#NonNull ItemAdapter.ItemHolder holder, int position) {
Item item = listItems.get(position);
holder.viewName.setText(item.getName());
holder.viewPrice.setText(item.getPrice());
int as = item.getAvailabilityStatus();
if (as == 1) {
holder.viewAvailability.setChecked(true);
} else {
holder.viewAvailability.setChecked(false);
}
}
#Override
public int getItemCount() {
return listItems.size();
}
public class ItemHolder extends RecyclerView.ViewHolder {
private TextView viewName, viewPrice;
private CheckBox viewAvailability;
public ItemHolder(final View itemView) {
super(itemView);
viewName = itemView.findViewById(R.id.viewName);
viewPrice = itemView.findViewById(R.id.viewPrice);
viewAvailability = itemView.findViewById(R.id.viewAvailability);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
}
}
public ItemAdapter(Context context, List<Item> objects) {
this.context = context;
this.listItems = objects;
}
}

Insted of itemView.setOnClickListener use set clickListener on your cardView and use getAdapterPosition() to track which item you click
cardView= itemView.findViewById(R.id.cardView);
cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
int price = getThePrice(getAdapterPosition());
// use price here
}
});
you have to create getThePrice() method here which will return you the price of item you click.

list is not expanding / collapsing for second time

Problem: When I click on Custom/Random nothing is happening.
(please see screenshot below).
I implemented ExpandListView successfull using this example, but in my case data is coming from database, that is only difference. I debug my code, it is going inside expandAll() and when I run application, it is bydefault came with expanded list.
Screenshot of my current code, actually, I impl expandeListview in dialog box and inflate row using expandlistadapter

set onClickListener on Imageview(Listview) inside activity

Is there a way to set onClickListener on Imageview(Listview) inside activity ?
I'v created this , and it works just fine in my adapter, But it's not working in my activity :
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
playPause=(ImageView)view.findViewById(R.id.playPause);
Product m = productList.get(position);
playPause.setImageResource(m.getPlayPauseId());
playPause.setTag(position);
playPause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int pos = (Integer) v.getTag();
Product m =productList.get(pos);
if (paused) {
m.setPlayPauseId(R.drawable.ic_pause);
paused=false;
}else {
m.setPlayPauseId(R.drawable.ic_play);
paused = true;
}
adapter.notifyDataSetChanged();
}
});
}
And this is my Product class :
public class Product implements Serializable {
private int PlayPauseId;
#SerializedName("pid")
public int pid;
#SerializedName("name")
public String name;
#SerializedName("qty")
public int qty;
#SerializedName("price")
public String description;
#SerializedName("image_url")
public String image_url;
#SerializedName("date")
public String date;
public int getPlayPauseId() {
return PlayPauseId;
}
public void setPlayPauseId(int playPauseId) {
PlayPauseId = playPauseId;
}
}
Adapter Class (Fundapter library) :
public class FunDapter<T> extends BaseAdapter implements Filterable {
protected List<T> mDataItems;
protected List<T> mOrigDataItems;
protected LongExtractor<T> idExtractor;
protected final Context mContext;
private final int mLayoutResource;
private final BindDictionary<T> mBindDictionary;
private int oddColorRes;
private int evenColorRes;
private FunDapterFilter<T> funDapterFilter;
private Filter mFilter;
public FunDapter(Context context, List<T> dataItems, int layoutResource,
BindDictionary<T> dictionary) {
this(context, dataItems, layoutResource, null, dictionary);
}
public FunDapter(Context context, List<T> dataItems, int layoutResource,
LongExtractor<T> idExtractor, BindDictionary<T> dictionary) {
this.mContext = context;
this.mDataItems = dataItems;
this.mOrigDataItems = dataItems;
this.mLayoutResource = layoutResource;
this.idExtractor = idExtractor;
this.mBindDictionary = dictionary;
}
public void updateData(List<T> dataItems) {
this.mDataItems = dataItems;
this.mOrigDataItems = dataItems;
notifyDataSetChanged();
}
#Override
public int getCount() {
if (mDataItems == null || mBindDictionary == null) return 0;
return mDataItems.size();
}
#Override
public T getItem(int position) {
return mDataItems.get(position);
}
#Override
public boolean hasStableIds() {
if(idExtractor == null) return super.hasStableIds();
else return true;
}
#Override
public long getItemId(int position) {
if(idExtractor == null) return position;
else return idExtractor.getLongValue(getItem(position), position);
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View v = convertView;
final GenericViewHolder holder;
if (null == v) {
LayoutInflater vi =
(LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(mLayoutResource, null);
holder = new GenericViewHolder();
holder.root = v;
FunDapterUtils.initViews(v, holder, mBindDictionary);
v.setTag(holder);
} else {
holder = (GenericViewHolder) v.getTag();
}
final T item = getItem(position);
showData(item, holder, position);
return v;
}

you can do it with two ways:
Make an interface something like this
public interface ImageClick {
public imageButtonOnClick(View view, int position)
}
implement it in your activity, and in your adapter getView, set imageOnClickListener, and call this interface method inside that onClick, pass your position and view in it, so you can use position etc in your activity callback.
Second is to just make a method in your activity like in interface
public imageButtonOnClick(View view, int position)
in your adapter onClick method on imageView, call it something like
((YourActivity)context).imageButtonOnClick(params1, param2);

Custom your ArrayAdapter and set action in method getView
See this page
ListView with Add and Delete Buttons in each Row in android

For getting click the image in the list view in the activity itself you have to callback
Create an interface
public interface OnButtonClickListener {
public void onButtonClick(int position,View view);
}
in your actvity class implement OnButtonClickListener
you get a interface methood
#Override
public void onButtonClick(final int position, View view) {
int id = view.getId();
switch (id) {
case R.id.YOURIMAGEVIEWID:
//implent your process...
}
}
Create constructor in adapter calss
Context context;
OnButtonClickListener callback
public AdapterClass(Context context OnButtonClickListener buttonClickListener) {
this.context = context;
callback = buttonClickListener;
}
image click in adapter class
holder.imageView..setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
callback.onButtonClick(position, v);
}
});
in your actvity class
AdapterClass Adapter = new AdapterClass(youractivity.this, youractivity.this);
Add this class for callback
public class ListCustomClickEvents implements OnClickListener,View.OnTouchListener {
private int position;
private OnCustomClickListener callback;
// Pass in the callback (this'll be the activity) and the row position
public ListCustomClickEvents(OnCustomClickListener callback, int pos) {
position = pos;
this.callback = callback;
}
#Override
public void onClick(View v) {
callback.OnCustomClick(v, position);
}
}

Replace Recyclerview with LinearLayout

i am having a small problem with memory when i tried to used nested RecyclerView and it crashed because it was not recycling views and as a result it run out of memory. So i have to go with another solution. I have created my own layout which accepts a Adapter like this:
public class CustomTileLayout extends LinearLayout {
private Adapter mAdapter;
private Observer mObserver = new Observer();
public CustomTileLayout(Context context) {
super(context);
}
public CustomTileLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public Adapter getAdapter() {
return mAdapter;
}
public void setAdapter(Adapter mAdapter) {
if (mAdapter != null)
mAdapter.unregisterDataSetObserver(mObserver);
this.mAdapter = mAdapter;
mAdapter.registerDataSetObserver(mObserver);
mObserver.onChanged();
}
private class Observer extends DataSetObserver {
#Override
public void onChanged() {
final List<View> oldViews = new ArrayList<View>(getChildCount());
for (int i = 0; i < getChildCount(); i++)
oldViews.add(getChildAt(i));
final Iterator<View> iter = oldViews.iterator();
removeAllViews();
for (int i = 0; i < mAdapter.getCount(); i++) {
View convertView = iter.hasNext() ? iter.next() : null;
View newView = mAdapter.getView(i, convertView, CustomTileLayout.this);
addView(newView);
}
super.onChanged();
}
#Override
public void onInvalidated() {
removeAllViews();
super.onInvalidated();
}
}
}
and while i use it like:
tileHolder = (GameCategoriesTileViewHolder) holder;
section = (Section) items.get(position);
tileHolder.customTileLayout.setAdapter(new GameTileAdapter(section.getGames(), context, R.layout.row_small_tile));
Everything works fine so far but there is a problem. The problem is that it looks like this:
while i want it each row to have 3 tiles like this:
If i specify the child layout to be like the result since it is the same item it only populates the 1st tile and the next 2 are blank.
My adapter:
public class GameTileAdapter implements ListAdapter {
private List<Game> games;
private Context context;
private int resLayout = R.layout.row_small_tile;
private boolean isFavoriteFragmentView = false;
private PopupMenu popupMenu;
public GameTileAdapter(List<Game> games, Context context, int resLayout) {
this.games = games;
this.context = context;
this.resLayout = resLayout;
}
#Override
public void registerDataSetObserver(DataSetObserver observer) {
}
#Override
public void unregisterDataSetObserver(DataSetObserver observer) {
}
#Override
public int getCount() {
return games.size();
}
#Override
public Object getItem(int position) {
return games.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public boolean hasStableIds() {
return true;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View itemView = convertView;
SingleItemViewHolder holder;
if (itemView == null){
LayoutInflater vi;
vi = LayoutInflater.from(context);
itemView = vi.inflate(resLayout, parent, false);
holder = new SingleItemViewHolder(itemView);
holder.game_name.setText(games.get(position).getName());
if (games.get(position).getImageUri().isEmpty()){
holder.game_imageuri.setImageResource(R.drawable.ic_image_placeholder);
}else {
Picasso.with(context).load(games.get(position).getImageUri()).into(holder.game_imageuri);
}
holder.itemLineColor.setBackgroundColor(GameManager.getmInstance(context).getGameColor(games.get(position)));
}else {
holder = (SingleItemViewHolder)itemView.getTag();
}
return itemView;
}
#Override
public boolean areAllItemsEnabled() {
return true;
}
#Override
public boolean isEnabled(int position) {
return true;
}
private static class SingleItemViewHolder{
CardView cv;
TextView game_name;
TextView game_is_new;
TextView game_jackpot;
ImageView game_imageuri;
View itemLineColor;
Button favorite_button;
Button menu_button;
SingleItemViewHolder(View itemView) {
cv = (CardView)itemView.findViewById(R.id.root_layout);
game_name = (TextView)itemView.findViewById(R.id.game_name_text);
game_is_new = (TextView)itemView.findViewById(R.id.game_new_ribbon);
game_jackpot = (TextView)itemView.findViewById(R.id.game_jackpot_ribbon);
game_imageuri = (ImageView)itemView.findViewById(R.id.game_imageuri);
itemLineColor = (View)itemView.findViewById(R.id.single_line_color);
favorite_button = (Button)itemView.findViewById(R.id.favButton);
menu_button = (Button)itemView.findViewById(R.id.menu_button_tile);
}
}
#Override
public int getItemViewType(int position) {
return position;
}
#Override
public int getViewTypeCount() {
return games.size();
}
#Override
public boolean isEmpty() {
return games.isEmpty();
}
}
Any ideas of how i can get the result?

You can use a layout for inner RecyclerView and add inflate a layout dynamically.
#Override
public void onBindViewHolder(RecentErrorsAdapter.ViewHolder holder, int position) {
try {
ArrayList<String> innerArrayList = new ArrayList<String>();
innerArrayList = mDataset.get(position).getInnerDataList();
for (int i = 0; i < innerArrayList.size(); i++) {
LayoutInflater inflater = null;
inflater = (LayoutInflater) context.getApplicationContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View mLinearView = inflater.inflate(R.layout.your_layout, null);
/**
* getting id of row.xml
*/
TextView textName = (TextView) mLinearView
.findViewById(R.id.txt_name);
textName.setText(innerArrayList.get(i));
holder.lstProgramName.addView(mLinearView);
}
} catch (Exception e) {
e.printStackTrace();
}
}

RealmSearchAdapter not recylcing the view

I have a gridview with items that I can increase or diminish its values, what is happening is when I change the value of the item and scroll down the screen
and scroll back the change that I made is gone, and if I scroll down and up a couple times I can see the change that I made again, what am I missing here?
