The Art of Doing: Dive Into Android Development with Kotlin - Linear Layout Basics: Nested Layouts and Layout Weight

The video tutorial covers the basics of layout attributes in app design, focusing on gravity, orientation, and nesting of linear layouts. It demonstrates how to center content using gravity attributes and convert horizontal layouts to vertical ones. The tutorial also explains how to nest layouts and add buttons, emphasizing the use of layout weight to control spacing. Finally, it discusses adding margins for better spacing and concludes with a preview of more advanced layout designs.

What attribute is used to center content within a linear layout?

• Layout Margin

• Layout Width

• Layout Height

• Layout Gravity

How can you change a horizontal linear layout to a vertical one?

• By adjusting the layout width

• By setting the layout height

• By changing the orientation attribute

• By modifying the layout gravity

What does the layout weight attribute control?

• The alignment of text

• The distribution of space among elements

• The spacing between elements

• The color of the layout

How do you specify which dimension the layout weight should apply to?

• Set the dimension to fill parent

• Set the dimension to match parent

• Set the dimension to wrap content

• Set the dimension to zero DP

What happens if all elements in a layout have the same layout weight?

• They will overlap each other

• They will be aligned to the left

• They will be aligned to the right

• They will be evenly distributed

How can you ensure a new row is not nested inside an existing row?

• By adjusting the layout width

• By placing it outside the existing row in the layout editor

• By changing the layout gravity

• By setting the layout height to zero

What should you do if buttons in a new row do not appear on the screen?

• Set the layout height to wrap content

• Increase the layout width

• Change the layout gravity

• Decrease the layout weight

How can you add spacing around a layout?

• By setting the layout margin

• By changing the layout orientation

• By using the layout weight attribute

• By adjusting the layout gravity

What is the effect of setting a layout's margin to 5 DP?

• It changes the layout's color

• It adds spacing around the layout

• It centers the layout

• It increases the layout's width

What is a benefit of using nested linear layouts?

• They simplify the layout structure

• They limit the number of elements

• They allow for complex designs

• They reduce the app's performance
