[英]Custom View receives Activity/Fragment lifecycle callbacks?
I'm working on custom view that will be used as normal android view component. 我正在研究将用作普通android视图组件的自定义视图。 Is it possible to internally handle hosts (activity/fragment) lifecycle states?
是否可以在内部处理主机(活动/碎片)生命周期状态?
My goal is to avoid end users (devs) to override every lifecycle callback in order to sync states with my view, for example: 我的目标是避免最终用户(dev)覆盖每个生命周期回调,以便将状态与我的视图同步,例如:
@Override
protected void onStop() {
super.onStop();
if (myCustomView != null) {
myCustomView.onStop();
}
}
If you are using Architecture Components you can implement LifecycleObserver interface, then: 如果使用的是体系结构组件 ,则可以实现LifecycleObserver接口,然后:
@OnLifecycleEvent(Lifecycle.Event.ON_STOP)
@OnLifecycleEvent(Lifecycle.Event.ON_STOP)
注释视图的onStop()方法 ((LifecycleOwner)context).getLifecycle().addObserver(this)
((LifecycleOwner)context).getLifecycle().addObserver(this)
