Compose ConstraintLayout Quiz Pt 2

Welcome to the quiz on Working with ConstraintLayout in Compose! This quiz is designed to test your understanding of how to use the ConstraintLayout in Jetpack Compose, including concepts like constraints, bias, chains, guidelines, and barriers. Each question will challenge your knowledge of how to structure and manipulate layouts using ConstraintLayout to create responsive and adaptive UI designs. Whether you’re a beginner or looking to reinforce your learning, this quiz will help solidify the concepts covered in the chapter.

How is a ConstraintLayout defined in Compose?

By applying the arrange function to a Column composable.

By wrapping children in a LinearLayout function.

By using the Box() composable with constraints.

By adding a ConstraintLayout library and using ConstraintLayout{} composable.

None

What is the role of margins in ConstraintLayout constraints?

To fix the position of a composable at the center of the screen.

To create fixed distances between a composable and its constraint connections.

To animate the size changes of a composable.

To enable the composable to overlap other components.

None

How can the position of a composable be adjusted when using opposing constraints?

By using constraint bias.

By setting the composable’s elevation.

By adding more opposing constraints.

By changing the component’s padding.

None

When should barriers be used in ConstraintLayout?

To set absolute margins for all components.

To create a background behind components.

To dynamically adjust constraints based on the size of other components.

When needing to wrap all components into a single group.

None

Which function creates a horizontal barrier in ConstraintLayout?

createBottomBarrier()

createTopBarrier()

createHorizontalBarrier()

createVerticalBarrier()

None

What is the effect of setting a bias of 0.0f on a constraint?

The component will be positioned randomly within the layout.

The component will align completely to the start side.

The component will be centered between the constraints.

The component will be aligned to the end side.

None

How does the SpreadInside chain style arrange components?

It evenly distributes components across the entire parent.

It evenly spaces components between the first and last items, leaving margins.

It packs the components tightly together with no gaps.

It aligns all components to the left side.

None

What is the default behavior of a chain in ConstraintLayout?

SpreadInside

Spread

Centered

Packed

None

What does the createGuidelineFromStart() function do?

Creates a fixed distance margin for all composables.

Creates a vertical guideline from the start (left) of the layout.

Generates a diagonal guideline across the layout.

Creates a horizontal guideline from the top of the layout.

None

10.

What is the purpose of the constrainAs() function in ConstraintLayout?

To wrap composables in a scrollable view.

To define padding for a composable.

To animate the position of a composable.

To assign a reference to a composable and define its constraints.

None

11.

What is the purpose of a guideline in ConstraintLayout?

To provide a reference line for aligning components.

To add scroll functionality to a layout.

To create a fixed background color for all children.

To group components together for animation.

None

12.

How does the createEndBarrier() function work?

It adjusts its position based on the end edges of the referenced components.

It groups multiple barriers into a single unit.

It fixes the end position of all components within the layout.

It creates a barrier positioned at the start of a layout.

None

13.

How does Dimension.fillToConstraints affect a composable?

It allows the composable to fill the available space defined by constraints.

It aligns the composable to the center of the screen.

It ensures that the composable is always square.

It sets the size of the composable based on its content only.

None

14.

What is the main purpose of ConstraintLayout in Compose?

To create flexible and responsive user interface layouts.

To ensure that composables are always aligned with the screen edges.

To allow for basic stacking of composables.

To simplify the creation of animations between composables.

None

15.

What is a key advantage of using ConstraintSets in ConstraintLayout?

They allow for decoupling constraints, making them reusable and adaptable to different scenarios.

They make the layout components scrollable.

They automatically apply animations to constraints.

They simplify applying constraints to individual composables.

None

16.

Which function is used to center a composable horizontally relative to its parent?

centerHorizontallyTo()

centerTo()

centerAround()

alignHorizontally()

None

17.

Which statement is true about the createRefFor() function?

It links the composable directly to the parent ConstraintLayout.

It can only be used within Row and Column layouts.

It generates references for all child composables at once.

It creates a reference for a composable within a ConstraintSet.

None

18.

Which function would you use to define a horizontal chain between components?

createHorizontalChain()

linkChain()

createChain()

constrainChain()

None

19.

What happens when opposing constraints are applied to a composable along the same axis?

The composable is removed from the layout.

The composable is constrained to the nearest edge.

The composable is positioned in the center along that axis.

The composable is aligned to the leftmost side.

None

20.

Which function is used to create multiple references at once for ConstraintLayout?

createRef()

createMultiple()

createRefFor()

createRefs()

None
