For saving in SharedPreferences:

public void putListInt(String key, ArrayList<Integer> intList) {
    checkForNullKey(key);
    Integer[] myIntList = intList.toArray(new Integer[intList.size()]);
    preferences.edit().putString(key, TextUtils.join("‚‗‚", myIntList)).apply();
}

For retrieving from SharedPreferences:

public ArrayList<Integer> getListInt(String key) {
    String[] myList = TextUtils.split(preferences.getString(key, ""), "‚‗‚");
    ArrayList<String> arrayToList = new ArrayList<String>(Arrays.asList(myList));
    ArrayList<Integer> newList = new ArrayList<Integer>();

    for (String item : arrayToList)
        newList.add(Integer.parseInt(item));

    return newList;
}

You can use Set(form Java Collection) to store more than one Integer values in Shared Preferences.

Use the Gson for storing array in SharedPreferences

For storing value.

int[] list = new int[10];
String string=new Gson().toJson(list);
prefs.edit().putString("data", string).apply();

For fetching value.

String data=prefs.getString("data",null);
int [] list=new Gson().fromJson(data,int[].class);
