推荐答案

事件处理程序不处理键状态，仅处理事件.而且事件永远不会在一起. 您不能同时按向左键和向上键；这些事件之一将永远是第一个.

也就是说，您始终只需要检测按下和释放一个键的事件.您应该从这些事件中推断出键状态，并在事件之间的数据中记住它.这样，您就可以始终了解感兴趣的键的状态.

我现在不想给您代码示例，因为您甚至都没有标记要使用的UI库(总是标记它！).

Event handlers do not deal with key status, they deal with events only; and the events are never comes together. You cannot press Left and Up at the same time; one of those events will always be the first.

That said, you always need to detect the event of pressing and releasing of one key only. You should infer the key state from these event and remember it in your data between events. This way, you can always know the state of the keys of interest.

I don''t want to give you a code sample right now, because you did not even tag a UI library you want to use (always tag it!).
