- [Instructor] Let's an on-click listener to the title view…so that when someone click on it, we will toggle the status…from Favorite to Not Favorite and vicey versa.…In line 39, right after you set selected for the title view,…add an on click listener titleView.setonclicklistener…and then new on click listener.…Inside the on click function, we will first call toggle to…save the state to be the opposite of what is showing.…
Boolean result equal favorites dot toggle,…and we'll pass the recipe id.…Right now, there are red lines under the word recipe.…First, alt enter, and make recipe final.…After we toggle, we will need to update the UI.…So we will do title view dot set selected,…and then we'll pass in the result.…
Let's run the app. Press the green triangle.…Once again, we'll click on chocolate pudding,…and this time, we will click on the star…to see that it has turned solid.…Go back to main activity…and click on chocolate pudding again.…Yea!…It stays solid, meaning that our app has remembered that…we indeed like chocolate pudding.…
