How to get Spinner value?

String text = mySpinner.getSelectedItem().toString();
How to get spinner value after item select in spinner
If you don't want to use a custom adapter then fetch selected spinner position and using that position fetch your State model
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// int position = spinnerState.getSelectedItemPosition();
if(position >= 1){
AllStates allStates = stateList.get(position - 1)
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
Now you can access id from allStates model
How to get Spinner selected item value to string?
Try this:
String text = mySpinner.getSelectedItem().toString();
Like this you can get value for different Spinners.
How to get the Spinner value to save in a variable
You need to implement OnItemSelectedListener and override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// An item was selected. You can retrieve the selected item using
// parent.getItemAtPosition(pos)
}
public void onNothingSelected(AdapterView<?> parent) {
// Another interface callback
}

How to pass or get the spinner value to a string in android?
Declare selectdate as static public static LocalDate selectdate;
Create a method named getSelectDate and call it to get changed value , such as inside onCreate, inside onItemSelected of month_spinner and spinYear.
private void getSelectDate() {
//added
String month = month_spinner.getSelectedItem().toString();
String year = spinYear.getSelectedItem().toString();
//String month = textviewMonth.getText().toString();
//String year = textviewYear.getText().toString();
//combinedString = "16/09/2019";
combinedString = "01/" + month + "/" + year;
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MMMM/yyyy");
selectdate = LocalDate.parse(combinedString, formatter);
//
}
This will fix your button issue also. All is well . setMonthView roll backed to your old code . Here yours Class-
public class MainActivity extends AppCompatActivity implements CalendarAdapter.OnItemListener {
TextView monthYearText, textviewMonth, textviewYear, textviewYearnMonth;
RecyclerView calendarReyclerView;
public static LocalDate selectdate;
private Spinner month_spinner, spinYear;
String[] months;
String combinedString;
String selectedMonth;
String seltmont;
String selctYear;

//for testing
textviewYearnMonth = findViewById(R.id.textviewYearnMonth);
month_spinner = findViewById(R.id.month_spinner);
spinYear = findViewById(R.id.yearspin);
populateSpinnerMonth();
populateSpinnerYear();
initWidget();

To get "dd/MM/yyyy" this format use DateTimeFormatter.ofPattern("dd/MM/yyyy", Locale.ENGLISH).format(selectdate); , no other changes need .
To test -
@RequiresApi(api = Build.VERSION_CODES.O)
private void updateView() {
// combinedString = "01/" + mon + "/" + year ;
//not working
String mon = textviewMonth.getText().toString();
// Log.d("month","code is going here");
// textviewYearnMonth.setText(mon);
// Log.d("month","code cross the textviewYearnMonth");
textviewYearnMonth.setText(DateTimeFormatter.ofPattern("dd/MM/yyyy", Locale.ENGLISH).format(selectdate));
}
get spinner value and post to data base with volley
mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
//position is spinner position
//mySpinner.getSelectedItem().toString(); IS value of position (string)
mMap.put("your Key",mySpinner.getSelectedItem().toString());
//the value add to map of volley
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
