Android - Spinner : how may I distinguish user's actions from computer's actions in a OnItemSelectedListener

Tag : android , By : Laques

hope this fix your issue I've always solved that issue with boolean flags, it isnt pretty at all, but it works if you think it through.
The idea is more or less, create a global usable boolean and init with false, in the onSelectedItemListener() use that boolean to choose wether or not to trigger the action, the important thing to remember is to set it to true after the computer has selected it the first time automatically, and reset it to false in the onResume() method.
bool spinnerUsable1;
bool spinnerUsable2;
int positionSpinner;

public void onCreate(Bundle savedInstanceState){
   spinnerUsable1 = false;
   spinnerUsable2 = true;
   if(savedInstanceState != null){
      positionSpinner = savedInstanceState.getInt("posSpinner");
      if(positionSpinner != 0) spinnerUsable2 = false;

   //Declare your spinner, set the on item selected lister
   spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                boolean spinnerUsable = (spinnerUsable1 && spinnerUsable2);
                if (!spinnerUsable1) {
                    spinnerUsable1 = true;
                } else if (!spinnerUsable2) {
                    spinnerUsable2 = true;
                if (spinnerUsable) {

            public void onNothingSelected(AdapterView<?> arg0) {
                // Nothing

Android updating a spinner based on "Parent" spinner's selection - .notifyDataSetChange() not firing?

will be helpful for those in need You can just reassign the adapter after you got the updated array (account_name_array)
account_name_adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, account_name_array);

Manually typing in text in JavaFX Spinner is not updating the value (unless user presses ENTER)

I wish did fix the issue. Unfortunately, Spinner doesn't behave as expected: in most OS, it should commit the edited value on focus lost. Even more unfortunate, it doesn't provide any configuration option to easily make it behave as expected.
So we have to manually commit the value in a listener to the focusedProperty. On the bright side, Spinner already has code doing so - it's private, though, we have to c&p it
 * c&p from Spinner
private <T> void commitEditorText(Spinner<T> spinner) {
    if (!spinner.isEditable()) return;
    String text = spinner.getEditor().getText();
    SpinnerValueFactory<T> valueFactory = spinner.getValueFactory();
    if (valueFactory != null) {
        StringConverter<T> converter = valueFactory.getConverter();
        if (converter != null) {
            T value = converter.fromString(text);

// useage in client code
spinner.focusedProperty().addListener((s, ov, nv) -> {
    if (nv) return;
    //intuitive method on textField, has no effect, though
TextField field = new TextField();
TextFormatter fieldFormatter = new TextFormatter(
      TextFormatter.IDENTITY_STRING_CONVERTER, "initial");
fieldFormatter.valueProperty().addListener((s, ov, nv) -> {
    // do stuff that needs to be done on commit
} );
// normal setup of spinner
SpinnerValueFactory factory = new IntegerSpinnerValueFactory(0, 10000, 0);
// hook in a formatter with the same properties as the factory
TextFormatter formatter = new TextFormatter(factory.getConverter(), factory.getValue());
// bidi-bind the values

updating spinner based on another spinner's selected item

Any of those help Define your subcategory adapter (mSpnrSubCategory) as a global variable.
Then whenever category spinner click, change the data of subcategory then notifyDataSetChanged();
    ArrayAdapter<String> mSpnrSubCategory;
    ArrayList<String> aSubCategory;
    mSpnrCategory.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
         public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
               // SubCategories

My spinner adapter is not updating the spinner values on calling notifyDataSetUpdate change

wish of those help The Adapter holds the reference to the list passed in its constructor.
categories = dataBaseOperations.getInvertersType();
dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, categories);
List<Inverters> allData = inverter.getData();
DataBaseOperations dataBaseOperations = new DataBaseOperations(AdminPanelActivity.this);
