None

What happens when the enter and exit parameters are set to EnterTransition.None and ExitTransition.None in AnimatedVisibility?

The content slides into view.

The default fade animation is applied.

The content shrinks out of view.

No animations are applied when showing or hiding the content.

None

What does the tween() function allow you to do?

13.

What is the default alpha value for the fadeIn() function?

1.0

2.0

0.5

None

14.

How can multiple animation effects be combined in AnimatedVisibility?

By calling the functions sequentially.

Using the + operator.

With a custom animation spec.

Using the tween() function.

None

15.

What is the purpose of the animationSpec parameter in animation functions like fadeIn()?

To define the duration and easing of the animation.

To set the position of the animation.

To change the background color of the animation.

To define the size of the content being animated.

None

16.

What is the purpose of the repeatable() function in animation?

To make an animation loop a specified number of times.

To make an animation faster.

To create a smooth fade effect.

To delay the start of an animation.

None

17.

Which AnimatedVisibility function is used to shrink content from view behind a vertical clip bounds line?

shrinkHorizontally()

shrinkOut()

slideInHorizontally()

shrinkVertically()

None

18.

What is the purpose of the targetState parameter in the Crossfade composable?

It controls the size of the fade area.

It sets the duration of the fade.

It defines the background color of the fade.

It specifies which composable should be visible.

None

19.

Which component allows you to change animation parameters like duration and easing?

Crossfade

AnimationSpec

LayoutModifier

VisibleState

None

20.

What does the expandVertically() animation effect do?

Slides the content into view horizontally.

Fades the content out of view.

Shrinks the content vertically before disappearing.

Expands the content into view vertically.

None

21.

How can you make an animation start with a delay?

By applying a delay modifier to the composable.

By using the tween() function with a delayMillis parameter.

By using the fadeIn() function directly.

By setting the visible parameter to false.

None

22.

How can you ensure that an animation starts automatically in Jetpack Compose?

Applying the default animation behavior.

By using MutableTransitionState with targetState.

Setting the visible parameter to true.

Using the animateStart() function.

None

23.

What is the function of the 'enter' parameter in the AnimatedVisibility composable?

Defines the animation duration for all animations.

Determines the content of the composable.

Sets the starting position of the composable.

Defines the animation when the composable becomes visible.

None

24.

What does the expandIn() function do?

Slides content into view from the left.

Shrinks content from view along both axes.

Fades content in without resizing it.

Reveals content using both horizontal and vertical clipping.

None

25.

Which animation effect would you use to make content slide out of view to the left?
