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 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

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

alignHorizontally()

centerTo()

centerAround()

centerHorizontallyTo()

None

How does the SpreadInside chain style arrange components?

It packs the components tightly together with no gaps.

It aligns all components to the left side.

It evenly distributes components across the entire parent.

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

None

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

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

linkChain()

constrainChain()

createHorizontalChain()

createChain()

None

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

createRef()

createRefs()

createMultiple()

createRefFor()

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 removed from the layout.

The composable is constrained to the nearest edge.

The composable is positioned in the center along that axis.

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 simplify applying constraints to individual composables.

They make the layout components scrollable.

They automatically apply animations to constraints.

None

How does the createEndBarrier() function work?

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

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

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

It groups multiple barriers into a single unit.

None

10.

Which function creates a horizontal barrier in ConstraintLayout?

createTopBarrier()

createHorizontalBarrier()

createVerticalBarrier()

createBottomBarrier()

None

11.

When should barriers be used in ConstraintLayout?

To create a background behind components.

To set absolute margins for all components.

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

When needing to wrap all components into a single group.

None

12.

What is the default behavior of a chain in ConstraintLayout?

Centered

Packed

SpreadInside

Spread

None

13.

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

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

To wrap composables in a scrollable view.

To animate the position of a composable.

To define padding for a composable.

None

14.

What does the createGuidelineFromStart() function do?

Generates a diagonal guideline across the layout.

Creates a horizontal guideline from the top of the layout.

Creates a fixed distance margin for all composables.

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

None

15.

What is the main purpose of ConstraintLayout in Compose?

To create flexible and responsive user interface layouts.

To simplify the creation of animations between composables.

To allow for basic stacking of composables.

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

None

16.

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

By adding more opposing constraints.

By using constraint bias.

By setting the composable’s elevation.

By changing the component’s padding.

None

17.

Which statement is true about the createRefFor() function?

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.

It can only be used within Row and Column layouts.

None

18.

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 enable the composable to overlap other components.

To animate the size changes of a composable.

None

19.

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

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
