阅读时the example ，我注意到作者在MyActivity中创建了Runnable task。如果我关闭该 Activity ，系统将无法对其进行垃圾收集，因为可运行对象包含对 MyActivity 的隐式引用，对吗？只要可运行程序有效，该 Activity 就会一直存在。
如有错误，请指正。
最佳答案
看起来是正确的。
来自您的链接(尽管谈论的是 AsyncTask，而不是匿名 Runnable):
if it is an inner class of your Activity/Fragment, it holds an implicit reference to it, which is bad practice, because Activity/Fragment can be destroyed on configuration change, but they will be kept in memory while worker thread is alive; if it is declared as standalone or static inner class and you are using reference to a Context to update views, you should always check whether it is null or not"
关于java - 匿名可运行对象可防止 Android 对定义它的 Activity 进行垃圾收集，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40437863/
