SupportActivity.java（用于support库）
------------------------------
public class SupportActivity extends Activity implements LifecycleOwner {
private LifecycleRegistry mLifecycleRegistry = new LifecycleRegistry(this);
ComponentActivity.java（用于androidx库）
------------------------------
public class ComponentActivity extends Activity
implements LifecycleOwner, KeyEventDispatcher.Component {
private LifecycleRegistry mLifecycleRegistry = new LifecycleRegistry(this);
Fragment.java
------------------------------
public class Fragment implements ComponentCallbacks, OnCreateContextMenuListener, LifecycleOwner {
LifecycleRegistry mLifecycleRegistry = new LifecycleRegistry(this);
LifecycleOwner.java
------------------------------
public interface LifecycleOwner {
@NonNull
Lifecycle getLifecycle();
}

同时它们还是实现了 LifecycleOwner 接口，里面的 getLifecycle() 就是返回这个 mLifecycleRegistry 用的。
