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.

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 create a background behind components.

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

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 positioned in the center along that axis.

The composable is constrained to the nearest edge.

The composable is aligned to the leftmost side.

None

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

By using constraint bias.

By adding more opposing constraints.

By setting the composable’s elevation.

By changing the component’s padding.

None

How does the createEndBarrier() function work?

It groups multiple barriers into a single unit.

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.

None

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

What does the createGuidelineFromStart() function do?

Creates a fixed distance margin for all composables.

Generates a diagonal guideline across the layout.

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

Creates a horizontal guideline from the top of the layout.

None

How does Dimension.fillToConstraints affect a composable?

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.

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

None

How does the SpreadInside chain style arrange components?

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.

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

None

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

centerTo()

alignHorizontally()

centerAround()

None

10.

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

createMultiple()

createRefs()

createRefFor()

createRef()

None

11.

What is the purpose of a guideline in ConstraintLayout?

To provide a reference line for aligning components.

To group components together for animation.

To add scroll functionality to a layout.

To create a fixed background color for all children.

None

12.

What is the role of margins in ConstraintLayout constraints?

To enable the composable to overlap other components.

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 animate the size changes of a composable.

None

13.

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

To define padding for a composable.

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.

None

14.

Which function creates a horizontal barrier in ConstraintLayout?

createHorizontalBarrier()

createVerticalBarrier()

createBottomBarrier()

createTopBarrier()

None

15.

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

16.

What is the default behavior of a chain in ConstraintLayout?

Spread

Centered

Packed

SpreadInside

None

17.

What is the main purpose of ConstraintLayout in Compose?

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.

To simplify the creation of animations between composables.

None

18.

What is a key advantage of using ConstraintSets in ConstraintLayout?

They make the layout components scrollable.

They simplify applying constraints to individual composables.

They automatically apply animations to constraints.

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

None

19.

Which statement is true about the createRefFor() function?

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.

It can only be used within Row and Column layouts.

None

20.

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

constrainChain()

createChain()

linkChain()

createHorizontalChain()

None
