## 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](https://developer.android.google.cn/topic/libraries/architecture/viewmodel.html)
## Introduction
**LifecycleModel** 基于 Google 在 2017 年 I/O 大会上发布的 Android 架构组件中的 [**ViewModel**](https://developer.android.google.cn/topic/libraries/architecture/viewmodel.html), 可以帮助 **Activity** 和 **Fragment** 储存和管理一些与 UI 相关以及他们必需的数据, 避免数据在屏幕旋转或配置更改时发生的数据丢失, 还可以帮助开发者轻易实现 **Fragment** 与 **Fragment** 之间, **Activity** 与 **Fragment** 之间的通讯以及共享数据, 因为我看到 Google 让 **MVVM** 框架中的 **ViewModel** 具有了这些功能, 所以我也想让 **MVP** 框架中的 **Presenter**, 乃至其他更多的模块都具有这些功能, 所以 **LifecycleModel** 诞生了

## Lifecycle
## Download
``` gradle
implementation 'me.jessyan:lifecyclemodel:1.0.1'
```
## Usage
### Step 1
```java
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
```java
//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
```java
public class UserLifecycleModel implements LifecycleModel {
private Subject mSubject = PublishSubject.create();
public void doAction(String s) {
mSubject.onNext(s);
}
public void addAction(Action1 action) {
mSubject.subscribe(action);
}
}
public class AFragment extends Fragment {
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
UserLifecycleModel lifecycleModel = LifecycleModelProviders.of(getActivity()).get(UserLifecycleModel.class.getName());
lifecycleModel.addAction(new Action1() {
@Override
public void call(String s) {
// Update the UI.
}
});
}
}
public class BFragment extends Fragment {
@Override
public void onStart() {
super.onStart();
UserLifecycleModel lifecycleModel = LifecycleModelProviders.of(getActivity()).get(UserLifecycleModel.class.getName());
lifecycleModel.doAction("JessYan");
}
}
```
