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 center a composable horizontally relative to its parent?

alignHorizontally()

centerHorizontallyTo()

centerAround()

centerTo()

None

When should barriers be used in ConstraintLayout?

When needing to wrap all components into a single group.

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

To set absolute margins for all components.

To create a background behind components.

None

Which statement is true about the createRefFor() function?

It links the composable directly to the parent ConstraintLayout.

It generates references for all child composables at once.

It can only be used within Row and Column layouts.

It creates a reference for a composable within a ConstraintSet.

None

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

The composable is removed from the layout.

The composable is aligned to the leftmost side.

The composable is positioned in the center along that axis.

The composable is constrained to the nearest edge.

None

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

createRef()

createRefs()

createRefFor()

createMultiple()

None

What is the default behavior of a chain in ConstraintLayout?

Packed

Spread

SpreadInside

Centered

None

What is the purpose of a guideline in ConstraintLayout?

To add scroll functionality to a layout.

To create a fixed background color for all children.

To provide a reference line for aligning components.

To group components together for animation.

None

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

Creates a fixed distance margin for all composables.

None

Which function creates a horizontal barrier in ConstraintLayout?

createHorizontalBarrier()

createBottomBarrier()

createVerticalBarrier()

createTopBarrier()

None

10.

How is a ConstraintLayout defined in Compose?

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

By using the Box() composable with constraints.

By wrapping children in a LinearLayout function.

By applying the arrange function to a Column composable.

None

11.

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

createChain()

constrainChain()

createHorizontalChain()

linkChain()

None

12.

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

By using constraint bias.

By changing the component’s padding.

By adding more opposing constraints.

By setting the composable’s elevation.

None

13.

How does Dimension.fillToConstraints affect a composable?

It ensures that the composable is always square.

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.

None

14.

How does the SpreadInside chain style arrange components?

It evenly distributes components across the entire parent.

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

It aligns all components to the left side.

It packs the components tightly together with no gaps.

None

15.

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

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.

The component will be positioned randomly within the layout.

None

16.

What is a key advantage of using ConstraintSets in ConstraintLayout?

They simplify applying constraints to individual composables.

They make the layout components scrollable.

They automatically apply animations to constraints.

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

None

17.

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 creates a barrier positioned at the start of a layout.

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

None

18.

What is the role of margins in ConstraintLayout constraints?

To animate the size changes of a composable.

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

To enable the composable to overlap other components.

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

None

19.

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

20.

What is the main purpose of ConstraintLayout in Compose?

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.

To create flexible and responsive user interface layouts.

None
