Question

我要求在onCreate（）方法中发生这些类，并且它们在类的底部都有布尔值，一旦完成它们就会设置为true。只有这样，我的SurfaceView才能绘制它所需要的东西。为什么这三个课要花这么长时间才能完成？

敌人，云，＆amp; bullet是我在调用他们的类之前加载的所有位图

public class handleBullets extends AsyncTask<String, Integer, String>

                Enemy tempE = enemies.get(i);

可能是您的任务是串行执行的。尝试使用executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR)并行执行您的任务，而不是调用execute()。

AsyncTasks需要很长时间才能完成
