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 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 create fixed distances between a composable and its constraint connections.

To animate the size changes of a composable.

None

What does the createGuidelineFromStart() function do?

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.

Generates a diagonal guideline across the layout.

None

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

centerAround()

centerTo()

alignHorizontally()

centerHorizontallyTo()

None

What is the main purpose of ConstraintLayout in Compose?

To create flexible and responsive user interface layouts.

To allow for basic stacking of composables.

To simplify the creation of animations between composables.

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

None

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

createRef()

createRefFor()

createMultiple()

createRefs()

None

Which function creates a horizontal barrier in ConstraintLayout?

createHorizontalBarrier()

createTopBarrier()

createBottomBarrier()

createVerticalBarrier()

None

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

How does Dimension.fillToConstraints affect a composable?

It ensures that the composable is always square.

It aligns the composable to the center of the screen.

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

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

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 automatically apply animations to constraints.

They make the layout components scrollable.

They simplify applying constraints to individual composables.

None

10.

How is a ConstraintLayout defined in Compose?

By wrapping children in a LinearLayout function.

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

By using the Box() composable with constraints.

By applying the arrange function to a Column composable.

None

11.

What is the purpose of a guideline in ConstraintLayout?

To group components together for animation.

To create a fixed background color for all children.

To add scroll functionality to a layout.

To provide a reference line for aligning components.

None

12.

What is the default behavior of a chain in ConstraintLayout?

Centered

Spread

Packed

SpreadInside

None

13.

Which statement is true about the createRefFor() function?

It can only be used within Row and Column layouts.

It creates a reference for a composable within a ConstraintSet.

It generates references for all child composables at once.

It links the composable directly to the parent ConstraintLayout.

None

14.

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

The composable is constrained to the nearest edge.

The composable is aligned to the leftmost side.

The composable is removed from the layout.

The composable is positioned in the center along that axis.

None

15.

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

16.

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

By changing the component’s padding.

By adding more opposing constraints.

By using constraint bias.

By setting the composable’s elevation.

None

17.

When should barriers be used in ConstraintLayout?

When needing to wrap all components into a single group.

To create a background behind components.

To set absolute margins for all components.

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

None

18.

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

linkChain()

createChain()

createHorizontalChain()

constrainChain()

None

19.

How does the createEndBarrier() function work?

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

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.

None

20.

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
