How to use notifyDataSetChanged and setText inside a same onclick method

I need to use notifyDataSetChanged() and setText a value to a TextView inside onBindViewHolder. I tried to use both inside onClick method,
qtyIncrease.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
quantityText.setText("Good");
toatlPriceText.setText("250");
notifyDataSetChanged();
}
});
My adapter class,
public class CartCardviewAdapter extends RecyclerView.Adapter<CartCardviewAdapter.MyViewHolder> {
private Context context;
private ArrayList<CartCardviewModel> dataSet;
private ShoppingCart shoppingCart;
public static class MyViewHolder extends RecyclerView.ViewHolder {
TextView itemNameText, itemTypeText, itemDescText, unitPriceText, toatlPriceText, quantityText;
ImageView itemImage, removeIcon, qtyIncrease, qtyDecrease;
public MyViewHolder(final View itemView) {
super(itemView);
this.itemNameText = (TextView) itemView.findViewById(R.id.item_name_text);
this.itemTypeText = (TextView) itemView.findViewById(R.id.item_type_text);
this.itemDescText = (TextView) itemView.findViewById(R.id.item_desc_text);
this.unitPriceText = (TextView) itemView.findViewById(R.id.item_unit_price_text);
this.toatlPriceText = (TextView) itemView.findViewById(R.id.item_total_price_text);
this.quantityText = (TextView) itemView.findViewById(R.id.item_quantity_text);
this.itemImage = (ImageView) itemView.findViewById(R.id.item_image);
this.removeIcon = (ImageView) itemView.findViewById(R.id.item_remove_icon);
this.qtyIncrease = (ImageView) itemView.findViewById(R.id.cart_quantity_increase);
this.qtyDecrease = (ImageView) itemView.findViewById(R.id.cart_quantity_decrease);
}
}
public CartCardviewAdapter(ArrayList<CartCardviewModel> data) {
this.dataSet = data;
}

toatlPriceText.setText(String.valueOf(shoppingCart.getTotalPrice(listPosition)));
notifyDataSetChanged();
}
}
});
}
#Override
public int getItemCount() {
return dataSet.size();
}
}
but both don't work at a click. I need to go back and come to see the affected change. I could't understand the problem. Please help me

First This line #RequiresApi(api = Build.VERSION_CODES.N) is for too restrictive, take into consideration lower levels down the line. There are many ways to approach this problem, first you can use a RecyclerView.OnItemTouchListener to the recycler hosting the adaptor. Here is a detailed tutorial describing single and long click , Link. Another approach is the interface segration principle.
In the adaptor class, create a interface, with one method
method signature (View view, int position), depicts a view clicked with repective position in adaptor.
Declare a instance of this interface in the adaptor
Modify the contructor to accept a interface of that type
Let the class with the recylcler view instance implement above interface
Pass a new instance to the contructor in the implemented class
Then in the overriden method, change your text and call adaptor.notifyItemChanged(position)
oh, also, in the adaptor class where the views gets init , set onClicklistener with the interface instance.
This tutorial describes exactly the above in great detail,link.
Your welcome!

the click won't trigger from there , you need to set the click listener of the Image View "qtyIncrease" inside the ViewHolder not in "OnBindViewHolder"
public static class MyViewHolder extends RecyclerView.ViewHolder {
TextView itemNameText, itemTypeText, itemDescText, unitPriceText, toatlPriceText, quantityText;
ImageView itemImage, removeIcon, qtyIncrease, qtyDecrease;
public MyViewHolder(final View itemView) {
super(itemView);
this.itemNameText = (TextView) itemView.findViewById(R.id.item_name_text);
this.itemTypeText = (TextView) itemView.findViewById(R.id.item_type_text);
this.itemDescText = (TextView) itemView.findViewById(R.id.item_desc_text);
this.unitPriceText = (TextView) itemView.findViewById(R.id.item_unit_price_text);
this.toatlPriceText = (TextView) itemView.findViewById(R.id.item_total_price_text);
this.quantityText = (TextView) itemView.findViewById(R.id.item_quantity_text);
this.itemImage = (ImageView) itemView.findViewById(R.id.item_image);
this.removeIcon = (ImageView) itemView.findViewById(R.id.item_remove_icon);
this.qtyIncrease = (ImageView) itemView.findViewById(R.id.cart_quantity_increase);
this.qtyDecrease = (ImageView) itemView.findViewById(R.id.cart_quantity_decrease);
qtyIncrease.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
quantityText.setText("Good");
toatlPriceText.setText("250");
notifyDataSetChanged();
}
});
}

textview not visible in listview when a button is clicked on a particular row

I have an custom listview which contains button and textview. The textview visibility is gone. When the button text is "email" and if I click on button the textview should display below the button. But the last textview is always getting visible.
#Override
public View getView(final int i, View view, ViewGroup viewGroup) {
wantedUsers du = wusers.get(i);
final String mcontact = du.mcontact;
if(view==null) {
viewholder = new viewholder();
view = LayoutInflater.from(ws).inflate(R.layout.wantedmoviecustom, null);
viewholder.mcontwcustom = (Button)view.findViewById(R.id.mcontwcustom);
viewholder.mdisplayemail = (TextView) view.findViewById(R.id.mdisplayemail);
view.setTag(viewholder);
} else {
viewholder = (viewholder) view.getTag();
}
viewholder.mdisplayemail.setVisibility(View.GONE);
if(mcontact.contains("#")) {
viewholder.mcontwcustom.setText("Show Email");
viewholder.mdisplayemail.setText(mcontact);
} else {
viewholder.mcontwcustom.setText("Call");
}
viewholder.mcontwcustom.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(mcontact.contains("#")) {
int p=(Integer)view.getTag();
viewholder.mdisplayemail.setVisibility(View.VISIBLE);
// viewholder.mdisplayemail.setText(mcontact);
}
else
{
Uri call = Uri.parse("tel:" + mcontact);
Intent surf = new Intent(Intent.ACTION_DIAL, call);
ws.startActivity(surf);
}
}
});
viewholder.mcontwcustom.setTag(i);
return view;
}
below is my getview from custom adapter. So how can I make a textview visbile when a button clicked on particular row.

First, you need to create a Global variable
int positionOfButtonClick = -1;
then you need to update your position on button click and need to call notifyDataSetChanged();
like - :
viewholder.mcontwcustom.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
positionOfButtonClick = i;
notifyDataSetChanged();
//your other code
});
Then, in getView
you need to check the position and need to VISIBLE your textView like -:
if(i==positionOfButtonClick ){
viewholder.mdisplayemail.setVisibility(View.VISIBLE);
}
Now, your getView should be-:
#Override
public View getView(final int i, View view, ViewGroup viewGroup) {
wantedUsers du = wusers.get(i);
final String mcontact = du.mcontact;
if(view==null) {
viewholder = new viewholder();
view = LayoutInflater.from(ws).inflate(R.layout.wantedmoviecustom, null);
viewholder.mcontwcustom = (Button)view.findViewById(R.id.mcontwcustom);
viewholder.mdisplayemail = (TextView) view.findViewById(R.id.mdisplayemail);
if(i==positionOfButtonClick ){
viewholder.mdisplayemail.setVisibility(View.VISIBLE);
}else{
viewholder.mdisplayemail.setVisibility(View.GONE);
}
view.setTag(viewholder);
} else {
viewholder = (viewholder) view.getTag();
}
if(mcontact.contains("#")) {
viewholder.mcontwcustom.setText("Show Email");
viewholder.mdisplayemail.setText(mcontact);
} else {
viewholder.mcontwcustom.setText("Call");
}
viewholder.mcontwcustom.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(mcontact.contains("#")) {
int p=(Integer)view.getTag();
positionOfButtonClick = i;
notifyDataSetChanged();
}
else
{
Uri call = Uri.parse("tel:" + mcontact);
Intent surf = new Intent(Intent.ACTION_DIAL, call);
ws.startActivity(surf);
}
}
});
viewholder.mcontwcustom.setTag(i);
return view;
}

Change in code as mention below, I think it help you.
viewholder.mcontwcustom.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(mcontact.contains("#")) {
int p=(Integer)view.getTag();
viewholder.mdisplayemail.setVisibility(View.VISIBLE);
// viewholder.mdisplayemail.setText(mcontact);
}

RecyclerView onClick called every 7 rows

I have a recyclerView that use a adapter to bind view and perform click button on each view. But when i click on item 1, then the item += 7(ex: row 0, 7, 14,... will be changed UI due to onClick event trigger) also click too. Please help me.
Here's my viewholder code:
public MatchItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
View matchView = inflater.inflate(R.layout.match_item, parent, false);
MatchItemViewHolder matchItemViewHolder = null;
matchItemViewHolder = new MatchItemViewHolder(matchView);
return matchItemViewHolder;
}
I call onClick event here, i have to delete some definition because stackoverflow not let me post too much codes:
public class MatchItemViewHolder extends RecyclerView.ViewHolder {
public TextView txtTeamA;
public TextView txtTeamB;
public ImageView imvLive;
public Button btnPredict;
public boolean isLive = false;
public boolean hasUnderOver = false;
public MatchItemViewHolder(final View itemView) {
super(itemView);
txtTeamA = (TextView) itemView.findViewById(R.id.match_item_txt_teamA);
txtTeamB = (TextView) itemView.findViewById(R.id.match_item_txt_teamB);
txtRatioA = (TextView) itemView.findViewById(R.id.match_item_txt_ratioA);
txtRatioB = (TextView) itemView.findViewById(R.id.match_item_txt_ratioB);
txtPercentage = (TextView) itemView.findViewById(R.id.match_item_txt_percentage);
txtBetDirection = (TextView) itemView.findViewById(R.id.match_item_txt_betDirection);
txtMatchBo = (TextView) itemView.findViewById(R.id.match_item_txt_matchBo);
txtMatchNote = (TextView) itemView.findViewById(R.id.match_item_txt_matchNote);
txtMatchTime = (TextView) itemView.findViewById(R.id.match_item_txt_MatchTime);
txtMatchHour = (TextView) itemView.findViewById(R.id.match_item_txt_matchHour);
txtTourName = (TextView) itemView.findViewById(R.id.match_item_txt_TourName);
imvTeamA = (ImageView) itemView.findViewById(R.id.match_item_imv_TeamA);
imvTeamB = (ImageView) itemView.findViewById(R.id.match_item_imv_TeamB);
imvGameImage = (ImageView) itemView.findViewById(R.id.match_item_imv_GameImage);
imvLive = (ImageView) itemView.findViewById(R.id.match_item_imv_LiveImage);
btnPredict = (Button) itemView.findViewById(R.id.match_item_btn_Predict);
//set Item Click listener for item
btnPredict.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean winner = false;
PredictController predictController = new PredictController();
winner = predictController.getWinner(txtTeamA.getText().toString(), txtTeamB.getText().toString());
if (winner) {
txtBetDirection.setText("Xuôi nha");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
txtTeamA.setTextColor(context.getResources().getColor(R.color.colorPrimary, null));
txtTeamB.setTextColor(context.getResources().getColor(R.color.primary_text, null));
}else{
txtTeamA.setTextColor(ContextCompat.getColor(context, R.color.colorPrimary));
txtTeamB.setTextColor(ContextCompat.getColor(context, R.color.primary_text));
}
} else {
txtBetDirection.setText("Ngược nhé");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
txtTeamB.setTextColor(context.getResources().getColor(R.color.colorPrimary, null));
txtTeamA.setTextColor(context.getResources().getColor(R.color.primary_text, null));
}else{
txtTeamB.setTextColor(ContextCompat.getColor(context, R.color.colorPrimary));
txtTeamA.setTextColor(ContextCompat.getColor(context, R.color.primary_text));
}
}
}
});
}
}
And OnBindViewHolder Code:
#Override
public void onBindViewHolder(MatchItemViewHolder holder, int position) {
MatchesModel matchesModel = lstMatchItem.get(position);
holder.txtTeamA.setText(matchesModel.teamA);
holder.txtTeamB.setText(matchesModel.teamB);
holder.txtRatioA.setText(matchesModel.teamARatio);
holder.txtRatioB.setText(matchesModel.teamBRatio);
holder.txtPercentage.setText(matchesModel.teamPercentage);
holder.txtMatchBo.setText(matchesModel.matchBo);
if (matchesModel.matchDate != null) {
holder.txtMatchTime.setText(matchesModel.matchDate);
holder.txtMatchHour.setText(matchesModel.matchDate.split("\\s")[1]);
}
holder.txtMatchNote.setText(matchesModel.matchNote);
Picasso.with(context).load(matchesModel.teamAImage).fit().into(holder.imvTeamA);
Picasso.with(context).load(matchesModel.teamBImage).fit().into(holder.imvTeamB);
holder.txtTourName.setText(matchesModel.tourName);
Picasso.with(context).load(matchesModel.gameImage).fit().into(holder.imvGameImage);
UPDATE: I have figure it out how to solve the problem. Just use rclMatchItem.setItemViewCacheSize(100);
Set recyclerView cache view is the problem maybe default it's 7.
Thank you guys anyway.

Thanks guys, i found the solution for this problem.
In my Recycler Apdater I implement
public long getItemId(int position) {return position;}
Then use ItemCachedView for recyclerView rclMatchItem.setItemViewCacheSize(100);
And i never get repeat item every 7 rows anymore.

Change your onClickListener from ViewController to onBindView()
#Override
public void onBindViewHolder(MatchItemViewHolder holder, int position) {
holder.btnPredict.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean winner = false;
PredictController predictController = new PredictController();
winner = predictController.getWinner(txtTeamA.getText().toString(), txtTeamB.getText().toString());
if (winner) {
txtBetDirection.setText("Xuôi nha");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
txtTeamA.setTextColor(context.getResources().getColor(R.color.colorPrimary, null));
txtTeamB.setTextColor(context.getResources().getColor(R.color.primary_text, null));
}else{
txtTeamA.setTextColor(ContextCompat.getColor(context, R.color.colorPrimary));
txtTeamB.setTextColor(ContextCompat.getColor(context, R.color.primary_text));
}
} else {
txtBetDirection.setText("Ngược nhé");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
txtTeamB.setTextColor(context.getResources().getColor(R.color.colorPrimary, null));
txtTeamA.setTextColor(context.getResources().getColor(R.color.primary_text, null));
}else{
txtTeamB.setTextColor(ContextCompat.getColor(context, R.color.colorPrimary));
txtTeamA.setTextColor(ContextCompat.getColor(context, R.color.primary_text));
}
}
}
});
}

Create a boolean variable showWhoWinner varibale in your MatchesModel object.
In onBindViewHolder method setup click listener and make value of showWhoWinner variable invert.
btnPredict.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
matchesModel.setShowWhoWinner(!matchesModel.isShowWhoWinner);
notifyItemChanged(position);
}
And then in onBindViewHolder, put that condition of color changing:
if(matcherModel.isShowWhoWinner()){
boolean winner = false;
PredictController predictController = new PredictController();
winner = predictController.getWinner(txtTeamA.getText().toString(), txtTeamB.getText().toString());
if (winner) {
//Winner Color
} else {
//Default color
}
}
else{
//Default color
}
Hope this helps

As per your Custom RecyclerView adapter, I suggest you to use HashMap to store Values. After all Data Model is best option to load data in to RecyclerView.
HashMap<Integer, Integer> hashMapTest = new HashMap<>();
When user click on ImageButton then add following code:
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(hashMapTest.get(position) != null && hashMapTest.get(position) != false) {
// Code of Product Added to wish list..
hashMapTest.put(getPosition(), 1);
} else {
// Code of Product Removed to wish list..
hashMapTest.put(getPosition(), 0);
}
}
});
In your onBindViewHolder(ProductHolder holder, int position) add following code
if(hashMapTest.get(position) != null && hashMapTest.get(position) != false) {
// Show your ImageButton color Product Added to wish list..
} else {
// Show your ImageButton color Product Removed to wish list..
}
Hope it helps you.

Getting Text from Textview in Listview inflated Layout

I have a listview in which I inflate a layout with multiple textviews and buttons. I understand to get the text from a view that was clicked is ((Textview)view.... However I am trying to get the text from the specific textview that is located in the layout in which the user clicked. I have tried using OnItemClick but when I use this the item must be focused before the any of the buttons functions work. I resorted to and prefer using onClickListeners in the getView method of my custom adapter. So simply put, how do I click a Button and get the text that is in TextView that is located in the appropriate inflated layout list view item, given that since each inflated layout is considered as one list item?
UPDATE
Here are pictures to clarify what i am looking for. Both layouts are members of a listview.
I want to click the button with the date on it and get the text from the textview in the middle of the layout. However when I click the button with the date on it, I can only get the text from the textview in the middle of the layout of the last child. If "My Party" is the first child in the listview and "3303 going away service..." is the second child, when I click the date button the code in my custom adapter returns the text from the last loaded text in the view which will be "3303 going away service". What I am trying to do is when I click the date button on "My party", get the text "My party". Like wise with the second child.
Here is the getView() in my custom adapter.
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
viewHolder = new ViewHolder();
positionHolder = position;
Log.i("Position", "" + position);
if(convertView == null) {
try {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

Create a custom baseadapter and set on click listener for text view in the adapter. This will then be set for the specific text view corresponding to the position.

I think you already have custom BaseAdapter created, in the custom BaseAdapter setOnclicklistener of the textview to which you want the click to be registered.
Sample Code Below
public class M_Adapter extends BaseAdapter {
private LayoutInflater inflater = null;
private TextView contact_name;
private Context context;
private List<String> list;
private List<String> temp;

I solved this problem with two series of if/else statements. First, in my onBindViewHolder (your getView) I have some global String variables take on the value of the TextView I'm interested in. Second, in the onClick method, I have the ViewHolder tell me the position of the item clicked using the getPosition method. Last, I match the value of the position clicked with the String variables created in the first part and carry on from there.
public void onBindViewHolder(final ViewHolder holder, final int position) {
YelpAPI.businessNumber = position;
YelpAPI.queryAPI(YelpAPI.yelpApi, YelpAPI.yelpApiCli);
Picasso.with(mContext).load(YelpAPI.picture).into(holder.yelpPicture);
holder.textName.setText(YelpAPI.name);
holder.textRating.setText(YelpAPI.rating);
holder.textReviews.setText(YelpAPI.reviews);
holder.textAddressDetails.setText(YelpAPI.fullAddress);
holder.textInfo.setText(YelpAPI.moreInfo);
holder.textID.setText(YelpAPI.businessID);
---------- First...
if(position == 0){
firstBusiness = YelpAPI.businessID; //these three String variables get created above
} else if(position == 1){
secondBusiness = YelpAPI.businessID;
} else if (position == 2) {
thirdBusiness = YelpAPI.businessID;
}
holder.business.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
----------Second...
int specific = holder.getPosition();
----------Last...
String saveMe = "";
if(specific == 0){
saveMe = firstBusiness;
} else if(specific == 1){
saveMe = secondBusiness;
} else if(specific == 2){
saveMe = thirdBusiness;
}
Log.d("Clicked this item: ", String.valueOf(specific));`
