如何从Event对象中获取事件ID的长值？

Question

我使用Google Calendar API来获取活动。获取事件后，Event对象不包含事件ID的长值。我想通过Google日历应用将事件ID用于查看活动详情。

谁能告诉我怎么做？

  compile('com.google.apis:google-api-services-calendar:v3-rev125-1.20.0') {
    exclude group: 'org.apache.httpcomponents'
  }

我正在使用这种方法，但我认为这不是一个好习惯。

private static final String[] INSTANCE_PROJECTION = new String[]{
        CalendarContract.Instances.EVENT_ID,      // 0
        CalendarContract.Instances.BEGIN,         // 1
        CalendarContract.Instances.END,         // 1
        CalendarContract.Instances.TITLE          // 2
};

private static final int PROJECTION_ID_INDEX = 0;
private static final int PROJECTION_BEGIN_INDEX = 1;
private static final int PROJECTION_END_INDEX = 2;
private static final int PROJECTION_TITLE_INDEX = 3;

public long getEventId(String title) {

    Cursor cursor = contentResolver.query(builder.build(),
            INSTANCE_PROJECTION,
            null,
            null,
            null);

    long eventIDL = 0;
    long beginVal = 0;
    long endVal = 0;
    String _title = null;
    int size = cursor.getCount();
    while (cursor.moveToNext()) {

        // Get the field values
        eventIDL = cursor.getLong(PROJECTION_ID_INDEX);
        beginVal = cursor.getLong(PROJECTION_BEGIN_INDEX);
        endVal = cursor.getLong(PROJECTION_END_INDEX);
        _title = cursor.getString(PROJECTION_TITLE_INDEX);

        if (beginVal == eventDate.getDateStart() && endVal == eventDate.getDateEnd()) {
            if (title != null && _title != null) {
                if (title.equals(_title)) {
                    break;
                }
            }

            if (title == null && _title == null) {
                break;
            }

            if (title == null && _title != null && _title.isEmpty()) {
                break;
            }

            if (title != null && title.isEmpty() && _title != null && _title.isEmpty()) {
                break;
            }
        }
    }

    return eventIDL;
}
