If you have the position of your recyclerView list item. you can find the view with
TextView text1 = yourRecyclerView.findViewHolderForAdapterPosition(position).itemView.findViewById(R.id.text1);
and then get textView string.
String text1Str = text1.getText().toString();
System.out.println("my textView string : " + text1Str);

Is it possible declare many diferent TextView. Like tv_concept1, tv_concept2, tv_concept3... and so on.
Using a variable string? If the string is "1" it would declare tv_concept1. So it will change the tv_concept1 text to Hi. But if the variable is it 2 then other TextView will do it.
String textview = "tv_concept" + value;
TextView textview = findViewById(R.id.textview);
textview.setText("Hi");```
You could use an array of your object.

In my android application I am using spinner for selecting data.. and I created string array for strings that to be displayed in spinner. I put all the details in strings folder. I wanted the selected text t be displayed in edit text once the user selected item..
For example : spinner is used to select country codes suppose user selected USA
then the selected text will be like this
United States of America,+001
I don't need t take all the text and display it in edit text. I need only the text after comma, that is +001. So is there any way to get the text after the comma only
Spinner spinner = (Spinner)findViewById(R.id.spinner);
String text = spinner.getSelectedItem().toString();
I know this will display all text I want only text that dislpaying after comma
You can split your text on the comma:
String text = spinner.getSelectedItem().toString();
String[] splited_text = text.split(",");
text = splited_text[1];
Suppose the text is in a string name text. use this:
String[] temp = text.split(",")
String code = temp[1]; //+001 the code after , temp[0] contains the rest
String seperated[] = spinner.getSelectedItem().toString().split(",");
text = seperated[1];
This will return only "+001".
String code = text.substring(text.indexOf(','));
This is how to get string after last comma:
String founded;
Pattern p = Pattern.compile(".*,\\s*(.*)");
String dd = (String) "Your string, really, really2";
Matcher m = p.matcher(dd);
if (m.find()) {
founded = m.group(1); //returns "really2"
}
I know to get a string of a specific TextView in a ListView, I can do this:
ReviewUser = ((TextView) rowView.findViewById(R.id.labelUser))
.getText().toString();
What if I want to get the TextView itself?
The TextView is an integer and I simply want to get the TextView and add 1 to it.
So you already specified that you know how to get the specific text from your ListView. Since you want to modify that same TextView, the rest is simple. This code is lengthier just to show the steps.
TextView textView = (TextView) rowView.findViewById(R.id.labelUser)
String text = textView.getText().toString();
int num = Integer.valueOf (text).intValue() + 1;
textView.setText (""+num);
Also, if you are working with a String ArrayAdapter and you know the index of the row you want to modify, what you can do is (assuming arrayAdapter is initialized and index is your index variable):
String text = arrayAdapter.get(index);
arrayAdapter.remove (text);
arrayAdapter.insert ((Integer.valueOf (text).intValue() + 1 ) + "", index);
