Deat Team,

I want to save the values entered on a dynamically created table row edit text.

SharedPreferences Prefs1 = PreferenceManager.getDefaultSharedPreferences(this);

        String s = Prefs1.getString("s1", "");
        t2v.setText(s);

         TextWatcher textWatcher1 = new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {


                s1 = t2v.getText().toString();


                //To Save the data
                SharedPreferences Prefs1 = PreferenceManager.getDefaultSharedPreferences(AggreAscendingorder.this);
                SharedPreferences.Editor editor = Prefs1.edit();

                editor.putString("s1", s1);

                editor.apply();

            }

            @Override
            public void afterTextChanged(Editable s) {


            }
        };
        t2v.addTextChangedListener(textWatcher1);

Using my above code, when I am editing any values, it saves the last edited value on all the rows.

Can anyone correct where I am doing the mistake

You'd better upload the screenshot of your app in order for us to know the UI layout of your app and which the variable of t2v stands for.
