安德列斯:日历年度重叠事件说明
原标题：Android: Layout for overlapping events in calendar

I m目前正在编制一个日历表。 在用户选择“日观”时,他需要看到类似的例子:

http://postimage.org/image/2s Boxa22s/

I m not really sure how to do this as the layout must be created at runtime because the number of events, their duration, how many are overlapping etc. is variable.

我试图找到类似的问题,但却没有成功。

我的两分之四,像利用带线的“支线”的“支离破碎”来形容背景(有灰色线的黄色线)和把事件放在首位的另一种碎片。 只有这样,我才不敢肯定如何获得安置权,也不知道如何处理事件重叠的地方。

<>>>>>

既然不存在像安乐团这样的一刀(它根本得不到任何布局或植被的支持) 我必须拿出自己的解决办法。

简言之,我做了以下工作:

  1. Add a spacer (empty calendar) until I reach the start of the first appointment.
  2. Add first appointment to a list and then add all appointments that overlaps any one appointment in the list to the list.
  3. When there are no more overlapping appointments its time to add the list to the calendar.
  4. I run through the appointments again to determine which can be in the same column and which cannot.
  5. Add the required number of columns filling empty space between appointments with empty layouts.
  6. Repeat untill all appointments of the day are added.

这一解决办法基于以下一点: 固定最低高度。 这意味着,我至少要高一个任命。 在我的案件中,第60页。 然后,我发现任命时间最短,以图示我能够计算每项任命高峰的系数。 例如,如果任命时间最长为15分钟,系数为4。

这样一来,短期任用为15分钟,任期为15分钟,长期任用为60分钟,长期任用为240分钟。

我不认为这是一个最佳的解决办法,因为它不是100%的生机,而是迄今为止取得了工作。

问题回答

然而,我对你的问题进行了深思熟虑,发现你的布局设计没有什么问题,你必须通过确定看法的班子来开展各种活动,从而避免任何其它事件的重叠。
