Populate spinner with years dynamically in Android?

You're very close. Try this:

ArrayList<String> years = new ArrayList<String>();int thisYear = Calendar.getInstance().get(Calendar.YEAR);for (int i = 1900; i <= thisYear; i++) {    years.add(Integer.toString(i));}ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, years);Spinner spinYear = (Spinner)findViewById(R.id.yearspin);spinYear.setAdapter(adapter);

You just forgot to add

spinYear.setAdapter(adapter);

I hope it will help you.

static final String[] Months = new String[] { "January", "February",            "March", "April", "May", "June", "July", "August", "September",            "October", "November", "December" };

 // Set years        ArrayList<String> years = new ArrayList<String>();        int thisYear = Calendar.getInstance().get(Calendar.YEAR);        for (int i = 1900; i <= thisYear; i++) {            years.add(Integer.toString(i));        }        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, years);        Spinner spinYear = (Spinner)findViewById(R.id.spinnerYears);        spinYear.setAdapter(adapter);        // Set months        ArrayAdapter<String> adapterMonths = new ArrayAdapter<String>(this,                android.R.layout.simple_spinner_item, Months);        adapterMonths.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);        Spinner spinMonths = (Spinner)findViewById(R.id.spinnerMonths);        spinMonths.setAdapter(adapterMonths);        // Set days        ArrayList<String> days = new ArrayList<String>();        for (int i = 1; i <= 31; i++) {            days.add(Integer.toString(i));        }        ArrayAdapter<String> adapterDays = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, days);        Spinner spinDays = (Spinner)findViewById(R.id.spinnerDays);        spinDays.setAdapter(adapterDays);

I suggest the easy one:

ArrayList<String> yearsList = new ArrayList<>();int current_year = Calendar.getInstance().get(Calendar.YEAR);int count = 60;for (int i = 0; i < count; i++) {    yearsList.add(Integer.toString(current_year - i));}ArrayAdapter<String> yearsAdapter = new ArrayAdapter<>(getContext(), R.layout.dropdown_item, yearsList);spinYear.setAdapter(yearsAdapter);

Just change the value of int count with how many years you want to print prior to the current year.
