谁能告诉我如何在 android 活动中使用Caldroid 日历创建日期选择器？

这是一个示例应用程序：https ://github.com/roomorama/Caldroid/tree/master/caldroidSampleActivity

这是活动的代码：

@SuppressLint("SimpleDateFormat")
public class CaldroidSampleActivity extends AppCompatActivity {
    private boolean undo = false;
    private CaldroidFragment caldroidFragment;
    private CaldroidFragment dialogCaldroidFragment;

    private void setCustomResourceForDates() {
        Calendar cal = Calendar.getInstance();

        // Min date is last 7 days
        cal.add(Calendar.DATE, -7);
        Date blueDate = cal.getTime();

        // Max date is next 7 days
        cal = Calendar.getInstance();
        cal.add(Calendar.DATE, 7);
        Date greenDate = cal.getTime();

        if (caldroidFragment != null) {
            ColorDrawable blue = new ColorDrawable(getResources().getColor(R.color.blue));
            ColorDrawable green = new ColorDrawable(Color.GREEN);
            caldroidFragment.setBackgroundDrawableForDate(blue, blueDate);
            caldroidFragment.setBackgroundDrawableForDate(green, greenDate);
            caldroidFragment.setTextColorForDate(R.color.white, blueDate);
            caldroidFragment.setTextColorForDate(R.color.white, greenDate);
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final SimpleDateFormat formatter = new SimpleDateFormat("dd MMM yyyy");

        // Setup caldroid fragment
        // **** If you want normal CaldroidFragment, use below line ****
        caldroidFragment = new CaldroidFragment();

        // //////////////////////////////////////////////////////////////////////
        // **** This is to show customized fragment. If you want customized
        // version, uncomment below line ****
//       caldroidFragment = new CaldroidSampleCustomFragment();

        // Setup arguments

        // If Activity is created after rotation
        if (savedInstanceState != null) {
            caldroidFragment.restoreStatesFromKey(savedInstanceState,
                    "CALDROID_SAVED_STATE");
        }
        // If activity is created from fresh
        else {
            Bundle args = new Bundle();
            Calendar cal = Calendar.getInstance();
            args.putInt(CaldroidFragment.MONTH, cal.get(Calendar.MONTH) + 1);
            args.putInt(CaldroidFragment.YEAR, cal.get(Calendar.YEAR));
            args.putBoolean(CaldroidFragment.ENABLE_SWIPE, true);
            args.putBoolean(CaldroidFragment.SIX_WEEKS_IN_CALENDAR, true);

            // Uncomment this to customize startDayOfWeek
            // args.putInt(CaldroidFragment.START_DAY_OF_WEEK,
            // CaldroidFragment.TUESDAY); // Tuesday

            // Uncomment this line to use Caldroid in compact mode
            // args.putBoolean(CaldroidFragment.SQUARE_TEXT_VIEW_CELL, false);

            // Uncomment this line to use dark theme

            caldroidFragment.setArguments(args);
        }

        setCustomResourceForDates();

        // Attach to the activity
