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

createRefFor()

createRef()

createMultiple()

createRefs()

None

How does the createEndBarrier() function work?

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.

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

None

What is the main purpose of ConstraintLayout in Compose?

To allow for basic stacking of composables.

To create flexible and responsive user interface layouts.

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

To simplify the creation of animations between composables.

None

How does the SpreadInside chain style arrange components?

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

It evenly distributes components across the entire parent.

It aligns all components to the left side.

It packs the components tightly together with no gaps.

None

What is a key advantage of using ConstraintSets in ConstraintLayout?

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.

They make the layout components scrollable.

None

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

centerTo()

alignHorizontally()

centerHorizontallyTo()

centerAround()

None

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

By adding more opposing constraints.

By using constraint bias.

By changing the component’s padding.

By setting the composable’s elevation.

None

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

createChain()

constrainChain()

linkChain()

createHorizontalChain()

None

What is the role of margins in ConstraintLayout constraints?

To enable the composable to overlap other components.

To animate the size changes of a composable.

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

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

None

10.

What is the default behavior of a chain in ConstraintLayout?

Spread

Centered

Packed

SpreadInside

None

11.

When should barriers be used in ConstraintLayout?

To set absolute margins for all components.

When needing to wrap all components into a single group.

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

To create a background behind components.

None

12.

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

13.

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 links the composable directly to the parent ConstraintLayout.

It creates a reference for a composable within a ConstraintSet.

None

14.

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

To wrap composables in a scrollable view.

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

To animate the position of a composable.

To define padding for a composable.

None

15.

Which function creates a horizontal barrier in ConstraintLayout?

createBottomBarrier()

createTopBarrier()

createHorizontalBarrier()

createVerticalBarrier()

None

16.

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 group components together for animation.

To add scroll functionality to a layout.

None

17.

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 positioned in the center along that axis.

The composable is removed from the layout.

The composable is constrained to the nearest edge.

None

18.

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

It aligns the composable to the center of the screen.

None

19.

What is the effect of setting a bias of 0.0f on a constraint?

The component will be centered between the constraints.

The component will be aligned to the end side.

The component will align completely to the start side.

The component will be positioned randomly within the layout.

None

20.

What does the createGuidelineFromStart() function do?

Generates a diagonal guideline across the layout.

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

Creates a fixed distance margin for all composables.

Creates a horizontal guideline from the top of the layout.

None
