Duplicate checkbox when checked and row value disappears

I have an application in which there is a listview that displays values and when a row is pressed, the third value of the row will display a value.
Example is: third value is 30 and when it's pressed, it should be
divided by 6, so the answer should be 5.
But when I scroll and press a row in listview example: I pressed row1, there will be a duplicate checked row in row10 and the value of the third row returns to it's old value (30) for example.
Is there any way to keep the checkbox from duplicating and the value of the row preserved when clicked?
Here's my code for the adapter:
public class MyAdapter extends BaseAdapter {
private ArrayList<HashMap<String, String>> mData;
public MyAdapter(ArrayList<HashMap<String, String>> mData2) {
this.mData = mData2;
}
#Override
public int getCount() {
return mData.size();
}
#Override
public Object getItem(int i) {
return this.mData.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(int i, View convertView, ViewGroup viewGroup) {
View mView = convertView;
String betid = mData.get(i).get("betid");
ViewHolder holder ;
if (mView == null) {
Context context = viewGroup.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
mView = inflater.inflate(R.layout.row_layout, null,false);
holder = new ViewHolder();
holder.tx_number = (TextView) mView.findViewById(R.id.tx_number);
holder.tx_amount = (TextView) mView.findViewById(R.id.tx_amount);
holder.tx_counter = (TextView) mView.findViewById(R.id.tx_counter);
mView.setTag(holder);
} else {
holder = (ViewHolder) mView.getTag();
}
if (betid != null) {
String betnumber = mData.get(i).get("betnumber");
String amountTarget = mData.get(i).get("amountTarget");
String amountRamble = mData.get(i).get("amountRamble");
holder.tx_number.setText(betnumber);
holder.tx_amount.setText(amountTarget);
holder.tx_counter.setText(amountRamble);
}
return mView;
}
private class ViewHolder {
TextView tx_number;
TextView tx_amount;
TextView tx_counter;
}
}
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#RequiresApi(api = Build.VERSION_CODES.N)
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
CheckBox checkBox = (CheckBox)view.findViewById(R.id.checkmark);
TextView tv3 = (TextView)view.findViewById(R.id.tx_counter);
EditText editText = (EditText)findViewById(R.id.editText3);
String yy = editText.getText().toString().trim();
String shitts = listView.getItemAtPosition(position).toString();
ArrayList<String> list = new ArrayList<String>();
try {
String[] a = shitts.split(", ");
String[] b = a[1].split("=");
String[] sep = a[0].split("=");
String betnumber = sep[1];
String betamount= b[1];
checkBox.setChecked(!checkBox.isChecked());
if(checkBox.isChecked()){
//sort number
final String sorted = betnumber.chars().sorted().mapToObj(c -> Character.valueOf((char)c).toString()).collect(Collectors.joining());
//check if double digit
Boolean checker = doubleChecker(sorted);
if (checker == true){
Toast.makeText(getApplicationContext(),"DOUBLE DIGIT", LENGTH_SHORT).show();
int answer = Integer.parseInt(betamount) / 3;
tv3.setText(String.valueOf(answer));
}else{
Toast.makeText(getApplicationContext(),"NOT DOUBLE DIGIT", LENGTH_SHORT).show();
int answer;
if(yy.equals("")){
answer = Integer.parseInt(betamount) / 6;
tv3.setText(String.valueOf(answer));
}else{
answer = (Integer.parseInt(betamount) - Integer.parseInt(yy)) / 6;
tv3.setText(String.valueOf(answer));
}
}
//TODO save to array to send
}else{
//TODO mistake RETURN tv3 to old value // remove from array
tv3.setText("0");
}
}catch (Exception e){
}
}
});

I think the issue is here
if (betid != null) {
String betnumber = mData.get(i).get("betnumber");
String amountTarget = mData.get(i).get("amountTarget");
String amountRamble = mData.get(i).get("amountRamble");
holder.tx_number.setText(betnumber);
holder.tx_amount.setText(amountTarget);
holder.tx_counter.setText(amountRamble);
}
You are missing an elsestatement to set other values when betid is null.
If betid is null, other rows can hold values from previous rows.
...
holder.tx_amount.setText(amountTarget);
holder.tx_counter.setText(amountRamble);
} else {
// assuming that if betid is null, then, TextViews should be cleared
// or replace with your own values
holder.tx_number.setText("");
holder.tx_amount.setText("");
holder.tx_counter.setText("");
}

Textview Values of counter changes after scrolling Listview?

The Problem is :
I am having list of products in listview and a textview following incremenat/decrement buttons. If I perform increment and decrement on first item of the listview it changes to the other listview positions also while performing scrolling on it.
what all I have tried so far:
TextView's value changed while scrolling listview
TextView in listview rows showing repeated values on scroll in Android?
Duplicated entries in ListView
Android list items are changing when scrolling
I was not able to solve my problem with none of these.
I am stuck with this problem from last three days. Any one please help me with it I will be really grateful to you. Thanks

Add one variable in holder class that store value of quantity and set last quantity in it.
class ViewHolder{
int quanity
}
store that quantity
holder.quantity = your quantity
now you can get last quantity value from holder and place it to your textview.
/** set item name from the arrayList */
holder.txtItemName.setText(subProductDataList.get(position).getProductName());
holder.txtQuanity.setText(holder.quantity)
Hope this will help.

Duplicate data in ListView?

I have a ListView that fill from Sqlite . But when I fill the ListView I see Duplicate Data.
My Struct.class :
public class Struct{
public String IdS;
public String NameS;
public String Group;
}
My Activity.class :
ArrayAdapter adapter = new AdapterPSK(MPSK, activity, width, context);
ListView lstPa = (ListView) findViewById(R.id.lstPasokhgoo);
lstPa.setAdapter(adapter);
Struct stp = new Struct();
cursor_Sharee = sql.rawQuery("SELECT ID_P,Name_P,Group_P FROM ChatPasokhgo_tbl where Group_P = '" + "LOL" + "'", null);
try {
if (cursor_Sharee != null) {
if (cursor_Sharee.moveToFirst()) {
do {
stp.IdS = cursor_Sharee.getString(cursor_Sharee.getColumnIndex("ID_P"));
stp.NameS = cursor_Sharee.getString(cursor_Sharee.getColumnIndex("Name_P"));
stp.Group = cursor_Sharee.getString(cursor_Sharee.getColumnIndex("Group_P"));
MPSK.add(stp);
} while (cursor_Sharee.moveToNext());
}
}
} catch (Exception e) {
// TODO: handle exception
}finally{
cursor_Sharee.close();
}
adapter.notifyDataSetChanged();
MPSK is:
public ArrayList<Struct> MPSK = new ArrayList<Struct>();
My AdapterPSK.class :
public class AdapterPSK extends ArrayAdapter<Struct> {
static boolean enable = true;
static Activity activity;
static int widths;
public AdapterPSK(ArrayList<Struct> array,Activity act,int WIDTH,Context context) {
super(context, R.layout.chat_page, array);
activity = act;
widths = WIDTH;
}
public ViewHolder(View view)
{
txtName = (TextView) view.findViewById(R.id.txtname);
layoutRoot = (ViewGroup) view.findViewById(R.id.layoutRoot);
txtname = (TextView) view.findViewById(R.id.txtname);
}
public void fill(ArrayAdapter<Struct> arrayAdapter,final Struct item , int position)
{
MarginLayoutParams txtN = (MarginLayoutParams) txtname.getLayoutParams();
txtN.rightMargin = MarginRight;
txtname.setTextSize(TextSize);
if (item.NameS != null) {
txtName.setText(item.NameS);
}else if(item.NameE != null){
txtName.setText(item.NameE);
}
}
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
Struct item = getItem(position);
if(convertView == null)
{
convertView = G.inflater.inflate(R.layout.adapter_pasokhgoo,parent,false);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
}else {
holder = (ViewHolder) convertView.getTag();
}
holder.fill(this, item, position);
return convertView;
}
Notice : ListView show me last row of sqlite . But when I get Log see all of fetching data .My Query is true . My bug is from MPSK .

Your Struct stp = new Struct(); should be in :
do {
Struct stp = new Struct();
.....
......
} while (cursor_Sharee.moveToNext());
;)

Clear MPSK after retrieving cursor.. as
cursor_Sharee = sql.rawQuery("SELECT ID_P,Name_P,Group_P FROM ChatPasokhgo_tbl where Group_P = '" + "LOL" + "'", null);
MPSK.clear();
try
{
.....

Change this
if (cursor_Sharee != null) {
if (cursor_Sharee.moveToFirst()) {
do {
stp.IdS = cursor_Sharee.getString(cursor_Sharee.getColumnIndex("ID_P"));
stp.NameS = cursor_Sharee.getString(cursor_Sharee.getColumnIndex("Name_P"));
stp.Group = cursor_Sharee.getString(cursor_Sharee.getColumnIndex("Group_P"));
MPSK.add(stp);
} while (cursor_Sharee.moveToNext());
}
To
if (cursor_Sharee != null)
{
while(cursor_Sharee.moveToNext())
{
stp.IdS = cursor_Sharee.getString(cursor_Sharee.getColumnIndex("ID_P"));
stp.NameS = cursor_Sharee.getString(cursor_Sharee.getColumnIndex("Name_P"));
stp.Group = cursor_Sharee.getString(cursor_Sharee.getColumnIndex("Group_P"));
MPSK.add(stp);
}
}

Wrong Loading Data when using Viewholder in BaseAdapter Android

I am using BaseAdapter for loading the data in gridview. When the data is loaded to the gridview, and the user tries to scroll, I used to get incorrect data. In order to fix that I used ViewHolder. That actually fixed the issue, however, when the users click any of the data in the gridview, instead of getting the correct id from the item, all the items are returning a similar id number.
public class ProductAdapter extends BaseAdapter {
// Context context;

How can I change the background to a shape I already made, according to a string (I wish to change the status Bckgrnd)

arraylist.add(wp);
}
// Pass results to ListViewAdapter Class

// Binds the Adapter to the ListView

Do I need to paste my adapter too? The id of the TextView in the .xml layout is status.
My idea is to change the background to yellow if standy, red to finish and green to ongoing. I have a shape_"color".xml for each one.

And this is my shape.xml, example red.

<corners android:radius="10dp" />

Set the same shape to your list item just change the color inside getView wrt status.
try changing your getView to:

final ViewHolder holder;
if (view == null) {

holder.date = (TextView) view.findViewById(R.id.date);
holder.status = (TextView) view.findViewById(R.id.status);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
// Set the results into TextViews
holder.title.setText(coursepopulatelist.get(position).getTitle());
holder.date.setText(coursepopulatelist.get(position).getDate());
holder.status.setText(coursepopulatelist.get(position).getStatus());
//<<----------See the code below-------------------
int color = Color.RED;
String s=coursepopulatelist.get(position).getStatus();
if (s.trim().equals("ongoing")) {
color = Color.GREEN;
} else if (s.trim().equals("standby")) {
color = Color.YELLOW;
} else if (s.trim().equals("finished")) {
color = Color.RED;
}
GradientDrawable gd = (GradientDrawable) holder.status.getBackground();
gd.setColor(color);
// Listen for ListView Item Click
view.setOnClickListener(new OnClickListener() {
#Override

There's a few ways to do this, depending on how much memory you have available, etc. It seems like all you really want to do is to change the background color. Given that, I would do the following:
Create a HashMap that contains the colors you want indexed by the strings.
It seems you want to change the background of the individual item based on the string that it contains. In that case, you'll want to check the value of each string inside the view, and set the color based off of what it ends up with in the HashMap.
For instance.
static HashMap<String, Integer> colorMap=null;
//This should be run from the constructor
public populateMap () {
if (colorMap==null) {
colorMap=new HashMap<String,Integer>();
colorMap.add("finish",0xffff0000);
}
}
public View getView(int position, View convertView, ViewGroup parent)
String text; //Put in your text value here
TextView tv; // This is your view, I'm assuming a TextView
tv.setText(text);
if (colorMap.containsKey(text)) {
tv.setBackgroundColor(colorMap.get(text));
}
}
