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 purpose of a guideline in ConstraintLayout?

To add scroll functionality to a layout.

To provide a reference line for aligning components.

To create a fixed background color for all children.

To group components together for animation.

None

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 create flexible and responsive user interface layouts.

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

None

Which function creates a horizontal barrier in ConstraintLayout?

createBottomBarrier()

createHorizontalBarrier()

createVerticalBarrier()

createTopBarrier()

None

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

linkChain()

constrainChain()

createHorizontalChain()

createChain()

None

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

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

To animate the position of a composable.

To define padding for a composable.

To wrap composables in a scrollable view.

None

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

createRefs()

createMultiple()

createRef()

createRefFor()

None

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 removed from the layout.

The composable is positioned in the center along that axis.

The composable is aligned to the leftmost side.

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 create a background behind components.

To set absolute margins for all components.

None

What is the role of margins in ConstraintLayout constraints?

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 enable the composable to overlap other components.

To animate the size changes of a composable.

None

10.

Which statement is true about the createRefFor() function?

It can only be used within Row and Column layouts.

It links the composable directly to the parent ConstraintLayout.

It creates a reference for a composable within a ConstraintSet.

It generates references for all child composables at once.

None

11.

What does the createGuidelineFromStart() function do?

Creates a horizontal guideline from the top of the layout.

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.

None

12.

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 creates a barrier positioned at the start of a layout.

It groups multiple barriers into a single unit.

None

13.

How does the SpreadInside chain style arrange components?

It aligns all components to the left side.

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.

None

14.

What is the default behavior of a chain in ConstraintLayout?

Spread

Packed

Centered

SpreadInside

None

15.

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

centerHorizontallyTo()

centerTo()

alignHorizontally()

centerAround()

None

16.

How does Dimension.fillToConstraints affect a composable?

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

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

It aligns the composable to the center of the screen.

It ensures that the composable is always square.

None

17.

How is a ConstraintLayout defined in Compose?

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

By wrapping children in a LinearLayout function.

By using the Box() composable with constraints.

By applying the arrange function to a Column composable.

None

18.

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 be aligned to the end side.

The component will be centered between the constraints.

The component will align completely to the start side.

None

19.

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

By adding more opposing constraints.

By setting the composable’s elevation.

By using constraint bias.

By changing the component’s padding.

None

20.

What is a key advantage of using ConstraintSets in ConstraintLayout?

They automatically apply animations to constraints.

They simplify applying constraints to individual composables.

They make the layout components scrollable.

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

None
