Q & A

What is the main focus of the video?

The main focus of the video is designing the home fragment of an app, including adding a search icon, text views, a random meal card view, and setting up a horizontal recycler view for categories.

What are the three libraries mentioned in the video that are needed for the design?

The three libraries mentioned are for handling screen size changes, allowing the use of sdb and ssp units instead of dp or sp units.

How does the video suggest handling different screen sizes in the app design?

The video suggests using libraries that support sdb and ssp units to handle different screen sizes, which simplifies the process of adapting the design to various devices.

What is the purpose of adding a font to the project as described in the video?

Adding a custom font to the project is to ensure a consistent and visually appealing typography throughout the app, enhancing the user interface.

How does the video guide the creation of the 'Home' text view with a search icon?

The video guides the creation of the 'Home' text view with a search icon by placing them in a horizontal linear layout, setting appropriate constraints, and applying a custom font and text attributes.

What is the significance of the 'random meal' card view in the app design?

The 'random meal' card view is significant as it provides a visually appealing way to display meal options, likely with an image view, adding an engaging element to the user experience.

Why is a horizontal recycler view used for displaying popular items?

A horizontal recycler view is used for displaying popular items to allow for easy scrolling through a list of items, providing a smooth and efficient browsing experience.

How does the video address the issue of the categories not showing on smaller screens?

The video addresses the issue by suggesting the use of a nested scroll view to enable scrolling and ensure that the categories are visible on smaller screens.

What is the final step the video suggests to preview the app design?

The final step suggested is to make some edits to the design elements, such as adjusting the height of card views and previewing the app to ensure it aligns with the original design.

What is the next step mentioned in the video after completing the design?

The next step mentioned is to connect the app to an API and use Retrofit with the ViewModel, which will be covered in the next video.
