I have a TextView that stores a specific number of age And there are two buttons, increasing this number and decreasing, after I set a certain number in the textview, how can I save this number in the fragment by the button?

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
       
        View v =  inflater.inflate(R.layout.fragment_third, container, false);
 
 
        TextView age = (TextView) v.findViewById(R.id.age);
        Button button_add_age = (Button) v.findViewById(R.id.button_add_age);
        button_add_age.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (Integer.parseInt(age.getText().toString()) > 0) {
                    int age_value = Integer.parseInt(age.getText().toString()) + 1;
                    age.setText(String.valueOf(age_value));
                }
            }
        });
 
        Button button_remove_age = (Button) v.findViewById(R.id.button_remove_age);
        button_remove_age.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (Integer.parseInt(age.getText().toString()) > 1) {
                    int age_value = Integer.parseInt(age.getText().toString()) - 1;
                    age.setText(String.valueOf(age_value));
                }
            }
        });

*save button*
Button saveButton = (Button) v.findViewById(R.id.save_button);
         saveButton.setOnClickListener(new View.OnClickListener() {
             @Override 
             public void onClick(View v) {`enter code here`}
         });
