Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
LifecycleModel
The LifecycleModel class is designed to store and manage UI-related data in a lifecycle conscious way, the LifecycleModel class allows data to survive configuration changes such as screen rotations, it also handles the communication of the Activity / Fragment with the rest of the application, base on ViewModel
Introduction
LifecycleModel 基于 Google 在 2017 å¹´ I/O 大会上�?�布的 Android 架构组件ä¸çš„ ViewModel, �?�以帮助 Activity å’Œ Fragment 储å˜å’Œç®¡ï¿½?�一些与 UI 相关以�?�他们必需的数�?�, �?��?数�?�在�?幕旋转或�?置更改时�?�生的数�?�丢失, 还�?�以帮助开�?�者轻易实现 Fragment 与 Fragment 之间, Activity 与 Fragment 之间的通讯以�?�共享数�?�, å› ä¸ºæˆ‘çœ‹åˆ° Google 让 MVVM 框架ä¸çš„ ViewModel 具有了这些功能, 所以我也想让 MVP 框架ä¸çš„ Presenter, 乃至其他更多的模�?�都具有这些功能, 所以 LifecycleModel 诞生了

Step 1
public class UserLifecycleModel implements LifecycleModel {
private int id;
public UserLifecycleModel(int id) {
this.id = id;
}
void doAction() {
}
@Override
public void onCleared() {
//release resources
}
}Step 2
//Put data
LifecycleModelProviders.of(activity/fragment).put(UserLifecycleModel.class.getName(), new UserLifecycleModel(1));
//Get data
LifecycleModelProviders.of(activity/fragment).get(UserLifecycleModel.class.getName());
//Remove data
LifecycleModelProviders.of(activity/fragment).remove(UserLifecycleModel.class.getName());Communication of the Activity / Fragment
public class UserLifecycleModel implements LifecycleModel {
private Subject<String, String> mSubject = PublishSubject.create();
public void doAction(String s) {
mSubject.onNext(s);
}
public void addAction(Action1<String> action) {
mSubject.subscribe(action);
}
}

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
