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.

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 creates a reference for a composable within a ConstraintSet.

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 constrained to the nearest edge.

The composable is aligned to the leftmost side.

The composable is positioned in the center along that axis.

The composable is removed from the layout.

None

What is the purpose of a guideline in ConstraintLayout?

To create a fixed background color for all children.

To add scroll functionality to a layout.

To provide a reference line for aligning components.

To group components together for animation.

None

What does the createGuidelineFromStart() function do?

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

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.

None

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

To animate the position of a composable.

To wrap composables in a scrollable view.

To define padding for a composable.

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

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 effect of setting a bias of 0.0f on a constraint?

The component will be aligned to the end side.

The component will align completely to the start side.

The component will be centered between the constraints.

The component will be positioned randomly within the layout.

None

When should barriers be used in ConstraintLayout?

When needing to wrap all components into a single group.

To set absolute margins for all components.

To create a background behind components.

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

None

What is the role of margins in ConstraintLayout constraints?

To animate the size changes of a composable.

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

To enable the composable to overlap other components.

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

None

10.

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

createHorizontalChain()

createChain()

constrainChain()

linkChain()

None

11.

What is the main purpose of ConstraintLayout in Compose?

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.

To allow for basic stacking of composables.

None

12.

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

createMultiple()

createRefs()

createRef()

createRefFor()

None

13.

What is the default behavior of a chain in ConstraintLayout?

Packed

Centered

Spread

SpreadInside

None

14.

What is a key advantage of using ConstraintSets in ConstraintLayout?

They make the layout components scrollable.

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

They simplify applying constraints to individual composables.

They automatically apply animations to constraints.

None

15.

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

centerAround()

alignHorizontally()

centerHorizontallyTo()

centerTo()

None

16.

Which function creates a horizontal barrier in ConstraintLayout?

createTopBarrier()

createHorizontalBarrier()

createVerticalBarrier()

createBottomBarrier()

None

17.

How does the createEndBarrier() function work?

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.

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

None

18.

How is a ConstraintLayout defined in Compose?

By wrapping children in a LinearLayout function.

By applying the arrange function to a Column composable.

By using the Box() composable with constraints.

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

None

19.

How does Dimension.fillToConstraints affect a composable?

It aligns the composable to the center of the screen.

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

It ensures that the composable is always square.

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

None

20.

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
