Join David Gassner for an in-depth discussion in this video Creating a floating action button, part of Building a Note-Taking App for Android.
- My app now has a working button…that lets me go to the editor activity,…but it's an old style Android button.…Newer Android apps have something called…a floating action button.…You can see these buttons in apps like Contacts.…A floating action button appears in the lower right corner,…and it has material design animations.…You click it, and that takes you to…a new activity to create new data.…I'd like the same feature, but it turns out…that there isn't an easy to use floating action button…component in the Android SDK,…at least at this point.…
You can build it yourself by defining your own animations,…but some developers have created open source versions…of this component, and I'm going to use one of those.…I'm going to use the one at this Github repository…called android-circlebutton.…Now, you don't need any of this information up here…like the website URL.…Instead, we're going to use a Maven Dependency…to build in a link to this component in our project.…There are instructions for this at the bottom…of the screen of the home page.…
Building a Note-Taking App for iOS 8 and Building a Note-Taking App for Windows Phone 8 and Windows Store use the same assets to develop a similar app. Compare and contrast the steps and discover the similarities and differences between the three platforms.
- Understanding Android UI and data management patterns
- Creating an Android Studio project
- Customizing material design theme colors
- Defining an SQLite database structure
- Managing data with ContentProvider and Loader classes
- Retrieving and displaying data
- Customizing data display with a CursorAdapter
- Creating, updating, and deleting notes
- Preparing the app for deployment
