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.

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

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

To animate the position of a composable.

To define padding for a composable.

To wrap composables in a scrollable view.

None

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

constrainChain()

linkChain()

createHorizontalChain()

createChain()

None

How does Dimension.fillToConstraints affect a composable?

It ensures that the composable is always square.

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

It aligns the composable to the center of the screen.

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

None

How is a ConstraintLayout defined in Compose?

By using the Box() composable with constraints.

By applying the arrange function to a Column composable.

By wrapping children in a LinearLayout function.

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

None

Which statement is true about the createRefFor() function?

It creates a reference for a composable within a ConstraintSet.

It generates references for all child composables at once.

It can only be used within Row and Column layouts.

It links the composable directly to the parent ConstraintLayout.

None

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

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.

The composable is removed from the layout.

None

What is the role of margins in ConstraintLayout constraints?

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

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

To enable the composable to overlap other components.

To animate the size changes of a composable.

None

What is the main purpose of ConstraintLayout in Compose?

To allow for basic stacking of composables.

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

To create flexible and responsive user interface layouts.

To simplify the creation of animations between composables.

None

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

10.

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

alignHorizontally()

centerTo()

centerHorizontallyTo()

centerAround()

None

11.

What is a key advantage of using ConstraintSets in ConstraintLayout?

They simplify applying constraints to individual composables.

They automatically apply animations to constraints.

They make the layout components scrollable.

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

None

12.

What is the purpose of a guideline in ConstraintLayout?

To create a fixed background color for all children.

To provide a reference line for aligning components.

To add scroll functionality to a layout.

To group components together for animation.

None

13.

What is the default behavior of a chain in ConstraintLayout?

Spread

SpreadInside

Centered

Packed

None

14.

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 aligned to the end side.

The component will be centered between the constraints.

None

15.

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

createRefFor()

createRef()

createRefs()

createMultiple()

None

16.

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

17.

What does the createGuidelineFromStart() function do?

Creates a horizontal guideline from the top of the layout.

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.

None

18.

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

By using constraint bias.

By changing the component’s padding.

By setting the composable’s elevation.

By adding more opposing constraints.

None

19.

How does the SpreadInside chain style arrange components?

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

It aligns all components to the left side.

It evenly distributes components across the entire parent.

It packs the components tightly together with no gaps.

None

20.

Which function creates a horizontal barrier in ConstraintLayout?

createVerticalBarrier()

createHorizontalBarrier()

createTopBarrier()

createBottomBarrier()

None
