StaticViewModelStore

安卓跨Activity/Fragment/Service间即时传递数据，基于安卓MVVM，支持分屏&文档模式，支持自动释放

解决以下需求：

1. 多个Activity间进行数据观察观察
2. 跨多个Activity的各个Fragment间进行同一个数据观察
3. 同时在多个Activity间、多个Fragment间、多个Service间混合跨度对同一数据进行观察

使用方法

详见源码中app例子

Application

必要初始化

override fun onCreate() {
    super.onCreate()
    StaticViewModelStore.application = this
}

Activity

继承方式

class MyActivity : StaticViewModelLifecycleActivity() {}

委托方式

class MyActivity : AppCompatActivity(),
    StaticViewModelStore.StaticViewModelStoreCaller by StaticViewModelLifecycleActivity() {
    override fun onDestroy() {
        super.onDestroy()
        releaseStaticViewModel(isChangingConfigurations) //别忘了这个，忘了就内存泄漏
    }
}

Fragment

继承方式

class MyFragment : StaticViewModelLifecycleFragment() {}

委托方式

class MyFragment : Fragment(),
    StaticViewModelStore.StaticViewModelStoreCaller by StaticViewModelLifecycleFragment() {
    override fun onDestroy() {
        super.onDestroy()
        releaseStaticViewModel(requireActivity().isChangingConfigurations) //别忘了这个，忘了就内存泄漏
    }
}

Service

继承方式

class MyService : StaticViewModelLifecycleService() {}

委托方式

class MyService : LifecycleService(),
    StaticViewModelStore.StaticViewModelStoreCaller by StaticViewModelLifecycleFragment() {
    override fun onDestroy() {
        super.onDestroy()
        releaseStaticViewModel() //别忘了这个，忘了就内存泄漏
    }
}
