Stopping animations in Android Studio

I am trying to make an animation in android studio that will start when I double click the screen. Since I am using a scroll view and that takes up the whole screen I used that as the view to detect the double tap. I wanted 2 things to happen: 1. When ever I double tap the screen, the animation should start and stop. And 2. When I play with the volume rockers it will speed up the animation, e

Android: Java v. Python

除了通常的Python v。Java问题之外,是否有任何理由支持Python或Java在其他平台上开发Android手机? Java is "more native" on the Android platform; Python is coming after and striving to get parity but not quite there yet AFAIK. Roughly the reverse situation wrt App Engine, where Python's been around for a year longer than Java and so is still more mature and complete (even though Java&#

Android:Java v。Python

除了通常的Python v。Java问题之外,是否有任何理由支持Python或Java在其他平台上开发Android手机? Java在Android平台上是“更原生的”; Python正在努力争取获得平价,但还没有AFAIK。 与App Engine相反的情况大致相反,Python的使用时间比Java多一年,因此它仍然更加成熟和完整(即使Java正在赶上)。 所以,在任何情况下,如果部署应该发生在像Linux这样的通用平台上,那么您在Java和Python之间一成不变的情况下,我认为成

server" and "java

Is there any real practical difference between "java -server" and "java -client"? All I can find on Sun's site is a vague "-server starts slower but should run faster". What are the real differences? (Using JDK 1.6.0_07 currently.) This is really linked to HotSpot and the default option values (Java HotSpot VM Options) which differ between client and server

服务器“和”java

“java -server”和“java -client”之间是否有实际的区别? 我在Sun的网站上找到的所有内容都是模糊的“-server启动较慢,但应该运行得更快”。 真正的区别是什么? (目前使用JDK 1.6.0_07。) 这实际上与HotSpot和默认选项值(Java HotSpot VM选项)相关联,这些值在客户端和服务器配置之间有所不同。 从白皮书(The Java HotSpot Performance Engine Architecture)的第2章开始: JDK包含两种风格的虚拟机 - 客户端产品和
