将DatePicker DialogFragment设置为特定日期

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // 获取当前日期
        final Calendar calendar = Calendar.getInstance();
        int year = calendar.get(Calendar.YEAR);
        int month = calendar.get(Calendar.MONTH);
        int day = calendar.get(Calendar.DAY_OF_MONTH);

        // 创建DatePickerDialog实例
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    @Override
    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
        // 处理用户选择的日期
        // 在这里可以将选择的日期传递给其他组件或进行其他操作
    }
}

DatePickerFragment datePickerFragment = new DatePickerFragment();
datePickerFragment.show(getSupportFragmentManager(), "datePicker");
