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 does the createGuidelineFromStart() function do?

Creates a horizontal guideline from the top of the layout.

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

Creates a fixed distance margin for all composables.

Generates a diagonal guideline across the layout.

None

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

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 align completely to the start side.

The component will be positioned randomly within the layout.

None

What is the purpose of a guideline in ConstraintLayout?

To provide a reference line for aligning components.

To create a fixed background color for all children.

To group components together for animation.

To add scroll functionality to a layout.

None

What is the main purpose of ConstraintLayout in Compose?

To simplify the creation of animations between composables.

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

To create flexible and responsive user interface layouts.

To allow for basic stacking of composables.

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 a key advantage of using ConstraintSets in ConstraintLayout?

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.

They simplify applying constraints to individual composables.

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 aligned to the leftmost side.

The composable is removed from the layout.

The composable is constrained to the nearest edge.

None

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

centerHorizontallyTo()

alignHorizontally()

centerTo()

centerAround()

None

10.

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

createChain()

createHorizontalChain()

constrainChain()

linkChain()

None

11.

Which function creates a horizontal barrier in ConstraintLayout?

createBottomBarrier()

createHorizontalBarrier()

createVerticalBarrier()

createTopBarrier()

None

12.

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

By changing the component’s padding.

By setting the composable’s elevation.

By using constraint bias.

By adding more opposing constraints.

None

13.

What is the role of margins in ConstraintLayout constraints?

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.

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

None

14.

How does Dimension.fillToConstraints affect a composable?

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

It ensures that the composable is always square.

It aligns the composable to the center of the screen.

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

None

15.

What is the default behavior of a chain in ConstraintLayout?

Spread

Packed

Centered

SpreadInside

None

16.

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

17.

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

createRefFor()

createRef()

createMultiple()

createRefs()

None

18.

How does the createEndBarrier() function work?

It groups multiple barriers into a single unit.

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.

None

19.

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

20.

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

To wrap composables in a scrollable view.

To define padding for a composable.

To animate the position of a composable.

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

None
