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 a guideline in ConstraintLayout?

To create a fixed background color for all children.

To group components together for animation.

To add scroll functionality to a layout.

To provide a reference line for aligning components.

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

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

The composable is positioned in the center along that axis.

The composable is constrained to the nearest edge.

The composable is aligned to the leftmost side.

The composable is removed from the layout.

None

What is the default behavior of a chain in ConstraintLayout?

Centered

Packed

SpreadInside

Spread

None

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

linkChain()

createHorizontalChain()

createChain()

constrainChain()

None

Which function creates a horizontal barrier in ConstraintLayout?

createBottomBarrier()

createTopBarrier()

createVerticalBarrier()

createHorizontalBarrier()

None

Which statement is true about the createRefFor() function?

It creates a reference for a composable within a ConstraintSet.

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.

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 adding a ConstraintLayout library and using ConstraintLayout{} composable.

By wrapping children in a LinearLayout function.

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

10.

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

createMultiple()

createRefs()

createRef()

createRefFor()

None

11.

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

12.

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 dynamically adjust constraints based on the size of other components.

To create a background behind components.

None

13.

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 be centered between the constraints.

The component will be positioned randomly within the layout.

The component will align completely to the start side.

None

14.

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 animate the size changes of a composable.

To enable the composable to overlap other components.

None

15.

What is the main purpose of ConstraintLayout in Compose?

To allow for basic stacking of composables.

To simplify the creation of animations between composables.

To create flexible and responsive user interface layouts.

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

None

16.

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

alignHorizontally()

centerTo()

centerHorizontallyTo()

centerAround()

None

17.

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

18.

What is a key advantage of using ConstraintSets in ConstraintLayout?

They make the layout components scrollable.

They simplify applying constraints to individual composables.

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

They automatically apply animations to constraints.

None

19.

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 groups multiple barriers into a single unit.

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

None

20.

How does Dimension.fillToConstraints affect a composable?

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.

It ensures that the composable is always square.

None
