Differences Between Activities and Fragments in Android Development
Focus Keyword: Activities vs. Fragments in Android Development
Activities and fragments are essential components in Android development, but they serve different purposes and have distinct characteristics.
Activities:
An activity is a single, focused thing that the user can do. It represents a single screen with a user interface. Activities are crucial building blocks of an Android app and are used to interact with the users. Each activity has its lifecycle and is managed by the operating system.
Fragments:
A fragment is a reusable portion of a user interface that can be combined with other fragments in an activity to build a multi-pane UI. Fragments are used to design flexible and dynamic UIs that can adapt to different screen sizes and orientations. Unlike activities, fragments have their lifecycle but are dependent on their parent activity.
When to Choose Activities or Fragments:
When deciding between using activities or fragments in Android development, consider the following:
- Activities:
- - Use activities when you need a full-screen UI with its own navigation flow.
- - Activities are ideal for standalone screens or distinct functionalities.
- Fragments:
- - Use fragments when you want to create reusable UI components that can be combined in different ways within an activity.
- - Fragments are beneficial for creating modular and adaptive UI designs.
Ultimately, the decision to use activities or fragments depends on the specific requirements of your app and the design goals you want to achieve.
