Answer 1

所以我自己得到了它在布局中我有一个微调器，它由这个在简历上运行的方法填充和维护

    public void getCalendarsForCheckBox(){


    String[] projection =
            new String[]{
                    Calendars._ID,
                    Calendars.NAME,
                    Calendars.ACCOUNT_NAME,
                    Calendars.ACCOUNT_TYPE};

    Uri calendars = Uri.parse("content://calendar/calendars");
    ContentResolver cr = getContentResolver();
    Cursor managedCursor =
            getContentResolver().
                    query(Calendars.CONTENT_URI,
                            projection,
                            Calendars.VISIBLE + " = 1",
                            null,
                            Calendars._ID + " ASC");
    int j=0;
    if (managedCursor.moveToFirst()) {

        String calName;
        Integer calId;
        int nameColumn = managedCursor.getColumnIndex("name");

        int idColumn = managedCursor.getColumnIndex("_id");
        Integer i=0;
        do {

            calName = managedCursor.getString(nameColumn);

            if (!(calName == null)) {

                j++;
            }

        } while (managedCursor.moveToNext());

    }
//retrieving previously selected calendar (defaults to id 1)
    SharedPreferences prefs = getBaseContext().getSharedPreferences("prefs", MODE_PRIVATE);
    Integer theID = prefs.getInt("calendarID",1);
    Integer indexToSelect=0;
    String calTitles[] = new String[j];
    if (managedCursor.moveToFirst()) {

        String calName;
        Integer calId;
        int nameColumn = managedCursor.getColumnIndex("name");

        int idColumn = managedCursor.getColumnIndex("_id");
        Integer i=0;
        do {

            calName = managedCursor.getString(nameColumn);
            calId = Integer.parseInt(managedCursor.getString(idColumn));
            if (!(calName == null)) {
                if (calId.equals(theID))  indexToSelect = i;
                calTitles[i] = calName + "-" + calId;
                i++;
            }

        } while (managedCursor.moveToNext());

    }
    Spinner spinner = (Spinner) findViewById(R.id.spinner);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, calTitles); //selected item will look like a spinner set from XML


    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);
    spinner.setSelection(indexToSelect);

    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            String findTheIdSplit[] = ((TextView)selectedItemView).getText().toString().split("-");
            Integer TheID = Integer.parseInt(findTheIdSplit[findTheIdSplit.length-1]);

            SharedPreferences prefs = getBaseContext().getSharedPreferences("prefs", MODE_PRIVATE);
            SharedPreferences.Editor editor = prefs.edit();
            editor.putInt("calendarID",TheID);
            editor.commit();
//for committing the selected calendar

        }

        @Override
        public void onNothingSelected(AdapterView<?> parentView) {
            // your code here if needed
        }

    });

}
