You can add more than one animation effect to an element by listening to an end event of an animation
Listening for animated events-webkit-animation animations have three events: Start Event Webkitanimationstart, End Event Webkitanimationend, repeat motion event webkitanimationiterationIn the previous article, we demonstrated the effect of listening to an end event: CSS3 using animation to

B interface: Otheractivity.xmlWhen the This.finish () method is called, the B interface ends and the a interface is returned. As we can see, there is an overriding method in Mainactivity.java: Onactivityresult (). This method is provided by the system and can be overridden in "right-click->source->override/implement Methods".This method is called after Setresult () is returned, in which we determine if the return code is passed in the Otheractivity.java 30, and if so, the user name and password

This problem occurs because the previous animation has not been executed and you start the next animation. You look closely for animations before you have any other action on animations.Beginning to see this answer, I am smart is not the animation conflict?
