我只是在Activity上调用isDestroyed(),我得到了这个 ex:

我在列表中有活动,我想遍历它并完成所有活动:
for (Activity act : Variables.pastActivites) {
try {
Log.i("Killing: ", act.getLocalClassName());
if (!act.isDestroyed()) {
act.overridePendingTransition(0, 0);
act.finish();
}
else
{
Variables.pastActivites.remove(act);
}
} catch (Exception ex) {
Log.i("KillerAct: ", ex.toString());
}
}
我什至可以阅读官方文档,其中有一个名为 isDestroyed() 的函数。现在怎么办?
