- The Layout Editor helps you create the UI for your Android app.
- Almost everything you see on the screen of your app is a View.
- A TextView is a UI element for displaying text in your app.
- A ConstraintLayout is a container for other UI elements.
- Views need to be constrained horizontally and vertically within a ConstraintLayout.
- One way to position a View is with a margin.
- A margin says how far a View is from an edge of the container it's in.
- You can set attributes on a TextView like the font, text size, and color.
- The Resource Manager in Android Studio helps you add and organize your images and other resources.
- An ImageView is a UI element for displaying images in your app.
- ImageViews should have a content description to help make your app more accessible.
- Text that is shown to the user like the birthday greeting should be extracted into a string resource to make it easier to translate your app into other languages.
