JavaFX为什么AnimationTimer没有getStatus（）或类似的方法？ [英] JavaFX Why AnimationTimer has not getStatus() or similar method?
问题描述
AnimationTimer 没有一种方法可以知道它是否正在运行....我正面临这个问题，因为有时它会启动，有时候不会。
It seems pretty strange that AnimationTimer has not a method to know if it is running or not.... And i am facing this problem, cause sometimes it is starting and sometimes not.
解决方案在 handle（）方法中创建 volatile变量，并且每次在句柄内运行时都将其设置为true每次进入 stop（））方法使其成为假。所以我必须 @Override 这两种方法。
A solution is creating a volatile variable inside the handle() method and every time it is running inside the handle to make it true and every time it enters stop()) method to make it false.So i have to @Override both methods.

推荐答案
确实很奇怪，这种方法很缺失，但除了你和我之外，似乎没有人关心。我已经在4年多前报告了这个问题
，从那时起没有发生任何事情，虽然修复似乎是微不足道的。

It is indeed very strange that this method is missing but with the exception of you and me nobody seems to care. I have reported this issue more than 4 years ago and nothing has happened since then although the fix seems to be trivial. JDK-8092345
