Question

在我的活动中，我正在播放动画。当我第一次开始活动时，所有动画都在播放给定的持续时间。但是当我重复每一个动画更多的时间时它会加速。这是我的活动......而在我的代码中我没有提供所有对象和变量声明来减少代码......

公共类练习扩展活动{ /** 在第一次创建活动时调用。 * /

我不确定，但是如果您使用CountDownTimers并且多次按下它，则会启动它们两次或更多次。也许你的动画也是同样的问题。我看到swim_Animation.start();例如..在重新激活它之前尝试swim_Animation.stop();。我希望我没有误解你的解释..

为什么动画在首次运行后会加速？
