As the title states, the OnBackPressed method of the activity needs to be monitored in the rewritten component. How to implement it in the Component. Do you need to override onActivityBack?

在
Component拿到你要操作的activity实例，然后监听你想要的方法是的，重写
onActivityBack就可以。不过需要注意的是，需要在你的宿主Activity的onBackPressed方法中，调用WXSDKInstance的onActivityBack方法。
