使用setTime（）方法工作自定义MyAnalogClock。
花了一些时间后，我终于设法解决了这个问题。我希望这对某人有用。您只需调用setTime（hours，minutes，seconds）方法即可设置时间。

<?xml version="1.0" encoding="UTF-8"?><resources> <declare-styleable name="AnalogClock"> <attr name="dial" format="reference"/> <attr name="hand_hour" format="reference"/> <attr name="hand_minute" format="reference"/> </declare-styleable> </resources>
