When using setOnGroupClickListener method report an error “cannot find symbol”

When using setOnGroupClickListener method report an error “cannot find symbol”，
I try to use setOnGroupClickListener to register sublist click event listener to list control，But an error is reported during compilation
error report:

The line 329 is this
string level = infoAchie[1];

The problem is coming from the last comma you are adding in the string you are adding to your PlayerPrefs in this part:
if (!PlayerPrefs.HasKey(Achievement_data_key))
{
string achi = "";
for (int i = 1; i <= 22; i++)
{
achi += i + "-1-0-0,";
}
//Debug.Log("Create new achievement " + achi);
PlayerPrefs.SetString(Achievement_data_key, achi);
}
This code generates this string:
1-1-0-0,2-1-0-0,3-1-0-0,4-1-0-0,5-1-0-0,6-1-0-0,7-1-0-0,8-1-0-0,9-1-0-0,10-1-0-0,11-1-0-0,12-1-0-0,13-1-0-0,14-1-0-0,15-1-0-0,16-1-0-0,17-1-0-0,18-1-0-0,19-1-0-0,20-1-0-0,21-1-0-0,22-1-0-0,
Keep in memory that last comma at the end of the string.
You are later doing a split on the ',' character, and iterating over them.
string[] achie = achievement.Split(',');
for (int i = 0; i< dataAchievementCache.Length; i++)
{
//Debug.Log(achie[i]);
string[] infoAchie = achie[i].Split('-');
string group = infoAchie[0];
string level = infoAchie[1];
...
}
The problem is that by doing so, your achie string array contains an empty last element. So when you are later splitting on the "-" character, your infoAchie string array only contains one element: the empty string. The first line:
string group = infoAchie[0];
Still works, but is filled with the empty string. Then:
string level = infoAchie[1];
Can't work, as you are indeed out of the bounds of the infoAchie array.
The solution would be to add the comma to your string only if it is not the last element.
Also, I strongly advise you to use a StringBuilder over a simple string for optimization purposes. Your code could then look like, for instance:
if (!PlayerPrefs.HasKey(Achievement_data_key))
{
StringBuilder achi = new StringBuilder();
for (int i = 1; i <= 22; i++)
{
achi.Append(i).Append("-1-0-0");
if(i != 22)
achi.Append(",");
}
//Debug.Log("Create new achievement " + achi);
PlayerPrefs.SetString(Achievement_data_key, achi.ToString());
}
Which generates this string:
1-1-0-0,2-1-0-0,3-1-0-0,4-1-0-0,5-1-0-0,6-1-0-0,7-1-0-0,8-1-0-0,9-1-0-0,10-1-0-0,11-1-0-0,12-1-0-0,13-1-0-0,14-1-0-0,15-1-0-0,16-1-0-0,17-1-0-0,18-1-0-0,19-1-0-0,20-1-0-0,21-1-0-0,22-1-0-0

When I am going to incerase qty then below screen shows
when I am scrolled down and up then below screen shows

You are not setting the initial value of holder.tvQty in your onBindViewHolder method.
When you update the value of holder.tvQty in holder.btnPlus or holder.btnMinus listeners, you should save that value somewhere in your objSellerProductPOJO:
objSellerProductPOJO.setQty(final_str_qty)
Then under:
holder.tvPrice.setText(objSellerProductPOJO.getPrice());
add:
holder.tvQty.setText(objSellerProductPOJO.getQty());

You need to update the productListDetails variable on add or subtract after
holder.tvQty.setText(final_str_qty);
And notify the adapter using notifydatasetchange()

In your onClick() methods, replace the the position parameter of the onBindViewHolder() method with the getAdapterPosition().
Replace from
SellerProductPOJO objSellerProduct = productListDetails.get(position);
SellerProductPOJO objSellerProductDeduct = productListDetails.get(position);
to
SellerProductPOJO objSellerProduct = productListDetails.get(getAdapterPosition());
SellerProductPOJO objSellerProductDeduct = productListDetails.get(getAdapterPosition());

and it should be

total $
Thank You!
im using java in android studio.

You need to do context.getString(R.string.your_string), as R.string.your_string on its own is just a reference.

You have forgotten to call getString method in four places. I update your code :
private String createOrderSummary(int price, boolean cream, boolean chocolate,String nombre1)
{
String summary = getString(R.string.name) + nombre1;
if(cream && chocolate == false){
summary += "\n" + quantity + getString(R.string.SummaryChocolate);
}
if(chocolate && cream == false){
summary += "\n" + quantity + getString(R.string.SummaryCream);
}
if(chocolate && cream){
summary += "\n" + quantity + getString(R.string.SummaryBoth);
}
summary += "\nTotal: $" +price;
summary += "\n" + getString(R.string.Thankyou);
return summary;
}`enter code here`

Two layouts, one disabled

I have an Activity with a RadioGroup which contains 2 RadioButtons (rdbtn4, rdbtn5).
Then I have a XML file which contains to LinearLayouts:
linlay4 just contains 4 Spinners,
linlay5 five additional Spinners.
Then the user can set the Spinners as he likes and after pressing a button 2 TextViews are set with specific text (depends on the chosen Spinner values).
This is working flawlessly with linlay4, with linlay5 chosen the TextViews aren't set.
This is my code:

Your variable names are very cryptic, but I think I see what is wrong. Try changing the checks in your btnCalcWid around, like this:
btnCalcwid.setOnClickListener(new View.OnClickListener()

public void onClick(View v)

String s41 = String.valueOf(sp4Farbe1.getSelectedItemId()); //Farbe 1
String s42 = String.valueOf(sp4Farbe2.getSelectedItemId()); //Farbe 2
String s43 = String.valueOf(sp4Farbe3.getSelectedItemId()); //Multiplikator
String s44 = String.valueOf(sp4Farbe4.getSelectedItemId()); //Toleranz
int ds43 = Integer.parseInt(s43);
int ds44 = Integer.parseInt(s44);
rise1(ds43);
String snewTolerance = String.valueOf(getToleranceValue(ds44));
//Output:
tvWidResultValue.setText("" + s41 + s42 + "*10^" + ds43 + " Ohm");
tvWidToleranzValue.setText(""+ snewTolerance + " %");
}
else if (rdbtn5rings.isChecked())
{
String s51 = String.valueOf(sp5Farbe1.getSelectedItemId()); //Farbe 1
String s52 = String.valueOf(sp5Farbe2.getSelectedItemId()); //Farbe 2
String s53 = String.valueOf(sp5Farbe3.getSelectedItemId()); //Farbe 3
String s54 = String.valueOf(sp5Farbe4.getSelectedItemId()); //Multiplikator
String s55 = String.valueOf(sp5Farbe5.getSelectedItemId()); //Toleranz
int ds54 = Integer.parseInt(s54);
int ds55 = Integer.parseInt(s55);
rise1(ds54);
String snewTolerance = String.valueOf(getToleranceValue(ds55));
//Output:
tvWidResultValue.setText("" + s51 + s52 + s53 + "*10^" + ds54 + " Ohm");
tvWidToleranzValue.setText(""+ snewTolerance + " %");
}//else if
}//onClick
