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.

When should barriers be used in ConstraintLayout?

To set absolute margins for all components.

To create a background behind components.

When needing to wrap all components into a single group.

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

None

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

To wrap composables in a scrollable view.

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

To animate the position of a composable.

To define padding for a composable.

None

How does the SpreadInside chain style arrange components?

It evenly distributes components across the entire parent.

It packs the components tightly together with no gaps.

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

It aligns all components to the left side.

None

What is the purpose of a guideline in ConstraintLayout?

To add scroll functionality to a layout.

To group components together for animation.

To provide a reference line for aligning components.

To create a fixed background color for all children.

None

What is the role of margins in ConstraintLayout constraints?

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.

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

None

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

centerAround()

centerTo()

alignHorizontally()

centerHorizontallyTo()

None

Which function creates a horizontal barrier in ConstraintLayout?

createHorizontalBarrier()

createBottomBarrier()

createVerticalBarrier()

createTopBarrier()

None

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 simplify applying constraints to individual composables.

They automatically apply animations to constraints.

None

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

By setting the composable’s elevation.

By adding more opposing constraints.

By using constraint bias.

By changing the component’s padding.

None

10.

Which statement is true about the createRefFor() function?

It can only be used within Row and Column layouts.

It generates references for all child composables at once.

It links the composable directly to the parent ConstraintLayout.

It creates a reference for a composable within a ConstraintSet.

None

11.

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

createChain()

linkChain()

constrainChain()

createHorizontalChain()

None

12.

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

The component will be centered between the constraints.

The component will be aligned to the end side.

The component will align completely to the start side.

The component will be positioned randomly within the layout.

None

13.

What is the main purpose of ConstraintLayout in Compose?

To simplify the creation of animations between composables.

To allow for basic stacking of composables.

To create flexible and responsive user interface layouts.

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

None

14.

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

The composable is removed from the layout.

The composable is aligned to the leftmost side.

The composable is constrained to the nearest edge.

The composable is positioned in the center along that axis.

None

15.

How is a ConstraintLayout defined in Compose?

By using the Box() composable with constraints.

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

By wrapping children in a LinearLayout function.

By applying the arrange function to a Column composable.

None

16.

What is the default behavior of a chain in ConstraintLayout?

SpreadInside

Centered

Packed

Spread

None

17.

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

createRefFor()

createMultiple()

createRefs()

createRef()

None

18.

How does the createEndBarrier() function work?

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

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

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

It groups multiple barriers into a single unit.

None

19.

How does Dimension.fillToConstraints affect a composable?

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

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

It aligns the composable to the center of the screen.

It ensures that the composable is always square.

None

20.

What does the createGuidelineFromStart() function do?

Creates a fixed distance margin for all composables.

Generates a diagonal guideline across the layout.

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

Creates a horizontal guideline from the top of the layout.

None
