java - 如何获取 Activity 时间表的颜色？

Question

我正在创建一个事件。我也在创建时间表。事件是根据时间表 ID 创建的。我创建的动态事件 View 是为了显示事件。

我为此事件和时间表创建了两个表。并从数据库加载事件。 现在我已经从启用的时间表加载了事件。我已经为时间表设置了颜色。我想在具有受尊重的时间表 ID 的事件上显示这种颜色。

我尝试使用时间表的对象加载此颜色。

但是我使用了 for 循环，因此它向所有事件显示最后一个时间表的颜色。

如何为具有相关时间表 ID 的事件设置颜色？

编辑:

   public void showEvents()
{
    tableHelper = new TimeTableHelper(getActivity());
    tables = tableHelper.getAllTables();
    int color = 0;
    for (TimeTable table : tables) {

        int tableId = table.getId();
        int status = table.getStatus();

        mDb = new EventTableHelper(getActivity());
        events = mDb.getTimeTableEvents("Mon", tableId);


        for (EventData eventData : events) {

            int id = eventData.getId();
            String datefrom = eventData.getFromDate();

            if (datefrom != null) {
                String[] times = datefrom.substring(11, 16).split(":");
                minutesFrom = Integer.parseInt(times[0]) * 60 + Integer.parseInt(times[1]);
            }
            String title = eventData.getTitle();
            String location = eventData.getLocation();
            String dateTo = eventData.getToDate();

            color = table.getTableColor();

            String notification = eventData.getNotificationTime();

            if (dateTo != null) {
                //times = dateTo.substring(11,16).split(":");
                String[] times1 = dateTo.substring(11, 16).split(":");
                minutesTo = Integer.parseInt(times1[0]) * 60 + Integer.parseInt(times1[1]);
            }
            createEvent(inflater, dayplanView, minutesFrom, minutesTo, title, location, id, color, notification);
            id++;
        }

    }
}

尝试将两个 for 循环合并在一起，看看是否有效。 除了颜色之外，当进入第二个 for 循环时，事件看起来也被设置到最后一个表。

    for(TimeTable table : tables) {
        // code from table for loop
        // ...
        for(EventData eventData : events) {
            // code from event for loop.
            // ...
        }
    }
