A fragment is similar to an activity in that it usually controls visual presentation that’s defined in an XML layout file. An activity, though, uses the app’s entire displayable region, whereas a fragment is designed to be displayed within a rectangle that’s defined by its container: a FrameLayout or other ViewGroup component.
- A fragment is similar to an activity…in that it usually controls visual presentation…that's defined in an XML layout file.…An activity, though,…uses the app's entire displayable region,…whereas a fragment is designed to be displayed…within a rectangle that's defined by its container,…a FrameLayout or other ViewGroup component.…To demonstrate creating a first fragment,…I'll create a brand new project in Android Studio.…I'll name it FirstFragment.…
If you're following along,…you can create this project anywhere on your hard disk.…I'll accept the default Minimum SDK of API 15,…and then, for my activity,…I'll choose the Empty Activity template.…I'll click Next and then Finish to create the new project.…My project's main activity loads a layout file…called activity_main.…And that activity has a simple TextView component.…
And that's all the application is doing at this point.…If I look at the layout in Design View,…I see the TextView right here.…Now, I'm going to create my first fragment.…You can do this easily in Android Studio…
