Final answer:
Within a fragment class, a custom adapter is used to display appropriate data for the current tab, typically in scenarios involving Android app development with components like View Pagers and Lists.
Step-by-step explanation:
Within the class for a fragment, you can use a custom adapter to display appropriate data for the current tab. The Adapter pattern is a structural design pattern that allows objects with incompatible interfaces to collaborate. In the context of Android development, adapters are often used to connect the UI components of a fragment to the underlying data for that fragment.
For example, if you have a View Pager that allows the user to swipe between tabs, each tab may represent a fragment that contains a list or grid. An adapter would bridge the data for that list or grid (such as an Array Adapter for a List View or a Recycler View. Adapter for a Recycler View) to the fragment's UI elements, ensuring that each tab displays the correct content.
