所以"暂停"方法是让整个游戏停止,然后使用" startuj_sklep"(engish:start_shop)。 " startuj_sklep"方法开始新的活动。 它正在转变新的活动,但当它崩溃时。

答案 0 :(得分:0)
surfaceCreated()
中匿名类中的GameView
回调试图启动已经运行的线程,所以你得到了
java.lang.IllegalThreadStateException: Thread already started
添加一些日志记录以查看回调何时触发以及线程何时启动和停止。这样可以让您更好地了解应用与系统的互动方式。

(我不知道这是否是问题的一部分,但我强烈建议您不要让pause()
方法充当切换。您应该始终知道对pause()
的调用是否预期暂停或恢复,并将其写为切换会产生不必要的歧义。如果游戏暂停,并且您尝试暂停第二次,则应忽略第二个请求或报告错误,而不是尝试恢复它。)
