NavigationalTransition, NavigationalTransitionCompat

public abstract class BaseNavigationalTransition<T extends BaseNavigationalTransition>
extends Object

BaseNavigationalTransition represents a simple wrapper around window Transitions framework to simplify and also to made transitioning between two Activities independent from the current Android version, that is, to hide such transitions implementation from the context where it is used.

A specific navigational transition implementation may be associated with its corresponding activity class that can be supplied to BaseNavigationalTransition(Class) constructor. This class is used to create an instance of Intent that will be by default started whenever start(Activity) is invoked. Both onStart(Activity) and onFinish(Activity) methods cen be overridden by a specific transition implementations to match theirs specific needs.

Sample

 public abstract class DetailTransition extends BaseNavigationalTransition {

     DetailTransition() {
         super(DetailActivity.class);
     }

     @NonNull
     public static DetailTransition get() {
          return UiConfig.MATERIAL_SUPPORT ? new MaterialTransition() : new DefaultTransition();
     }

     @Override
     public Intent createIntent(@NonNull Activity caller) {
         final Intent intent = super.createIntent(caller);
         // ... put here any extras that need to be delivered to the called activity
         return intent;
     }

     static final class DefaultTransition extends DetailTransition {

          @Override
          protected void onStart(@NonNull Activity caller) {
              super.onStart(caller);
              // ... change activities with custom window animation
              WindowTransition.overrideStart(caller);
          }

          @Override
          protected void onFinish(@NonNull Activity caller) {
              super.onFinish(caller);
              // ... change activities without animation
              caller.overridePendingTransition(0, 0);
          }
     }

     // ... other implementations specific for a different platform versions

     static final class MaterialTransition extends DetailTransition {

          @Override
          protected void onStart(@NonNull Activity caller) {
              // ... made some modifications to the caller's UI (if necessary) before the transitions
              // ... are triggered.
              super.onStart(caller);
          }

          @Override
          protected void onFinish(@NonNull Activity caller) {
              super.onFinish(caller);
              // ... no need to override in most cases
          }
     }
 }
