- [Instructor] We have identified…the five things that RecipeActivity do.…Let's refactor them into the presenter one by one.…Step one only sets up the UI.…There is no logic…so it stays in the activity.…Step two extracts the recipe ID from the intent in line 30.…This part stays in the activity…because there's no other way to get hold of the intent.…In line 31 we use this ID to load the recipe.…
This can go inside the presenter…as long as the presenter is initialized with a RecipeStore.…So, let's do that.…In the UI Recipe folder that we created the contract,…right click, New, Java Class.…We will call it RecipePresenter.…Add a private final field RecipeStore,…private final RecipeStore…and we'll name it store.…Alt enter to add a constructor parameter.…
Now that we have a store,…we can use it to load the recipe…when someone give us an ID.…Add a new function.…Public void loadRecipe.…Pass it the ID as a string.…Recipe equal store.getRecipe ID.…Great, now we have a recipe.…What do we do with it?…We have two choices,…either return it back to the activity…
