カスタムアダプターの各スピナーの状態を取得する方法

私はテキストとスピナーを表示するカスタムアダプターを持っています。アクティビティが再び開いたときに同じアイテムを表示するように、各スピンナーの状態を保存しようとしました。私は別のものを試しましたが、私は成功していません。どうすればこのような感謝を達成できますか？これは私がカスタムアダプターの各スピナーの状態を取得する方法

CustomListAdapter(Context context, ArrayList<String> subjects) { 
    super(context, R.layout.custom_list_view, subjects); 
} 



@NonNull 
@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 

    LayoutInflater layoutInflater = LayoutInflater.from(getContext()); 
    View customView = layoutInflater.inflate(R.layout.custom_list_view, parent, false); 

    singleSubject = getItem(position); 


    TextView singleText = (TextView) customView.findViewById(R.id.listSubjectsMyCourses); 
    colorLayout = (LinearLayout)customView.findViewById(R.id.colorForSubjects); 
    relativeLayout = (RelativeLayout) 
    customView.findViewById(R.id.relativeForView); 
    parentLayout = (RelativeLayout) 
    customView.findViewById(R.id.parentLayout); 
    points = new ArrayList<>(); 
    selected = new ArrayList<>(); 
    selectedsttring = new ArrayList<>(); 
customView.findViewById(R.id.textViewForGrades); 
    tinyDB = new TinyDB(getContext()); 



     spinnerForGradePoints = (Spinner)customView.findViewById(R.id.spinnerForGrades); 
    final ArrayAdapter<String> gradePointAdapter = new ArrayAdapter<String>(getContext(), android.R.layout.simple_dropdown_item_1line, UserCourseSelection2.userSubjectGradePoint); 
    spinnerForGradePoints.setAdapter(gradePointAdapter); 

    spinnerForGradePoints.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { 
     @Override 
     public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) { 
      selectedItempos = adapterView.getSelectedItemPosition(); 
      String getSelectedItem = adapterView.getItemAtPosition(i).toString(); 

      tinyDB.putInt("selected", selectedItempos); 


     } 



     @Override 
     public void onNothingSelected(AdapterView<?> adapterView) { 

     } 
    }); 

    singleText.setText(singleSubject); 
    colorLayout.setBackgroundColor(UserCourseSelection2.userSubjectsListColor.get(position)); 
    int getSelected = tinyDB.getInt("selected"); 
    spinnerForGradePoints.setSelection(getSelected); 

    return customView; 

}
