Control animation duration and easing.

Modify the layout of a composable.

Set a specific position for animations.

None

14.

Which parameter is mandatory when using the AnimatedVisibility composable?

visible

exit

modifier

enter

None

15.

How can multiple animation effects be combined in AnimatedVisibility?

With a custom animation spec.

Using the tween() function.

Using the + operator.

By calling the functions sequentially.

None

16.

Which function is used for animating the replacement of one composable with another?

expandVertically()

animateContentSize()

Crossfade()

tween()

None

17.

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

18.

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

It specifies which composable should be visible.

It controls the size of the fade area.

It sets the duration of the fade.

It defines the background color of the fade.

None

19.

How can you make an animation start with a delay?

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

By setting the visible parameter to false.

By applying a delay modifier to the composable.

By using the fadeIn() function directly.

None

20.

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

To set the position of the animation.

To change the background color of the animation.

To define the size of the content being animated.

To define the duration and easing of the animation.

None

21.

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

slideOutHorizontally

fadeOut

shrinkVertically

expandHorizontally

None

22.

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

Using the animateStart() function.

Applying the default animation behavior.

By using MutableTransitionState with targetState.

Setting the visible parameter to true.

None

23.

What must be set to disable default animations in the parent AnimatedVisibility instance?

tween() duration to zero

animationSpec to null

scaleIn() with a value of zero

EnterTransition.None and ExitTransition.None

None

24.

What is the default behavior of AnimatedVisibility if no animation is specified?

It animates with a subtle fade.

It instantly shows or hides the content.

It slides the content into view.

It expands the content into view.

None

25.

What is the role of the 'targetState' in MutableTransitionState?

It modifies the color of the animated component.

It sets the initial size of the animation.

It adjusts the speed of the animation.

It determines the end state of the animation.

None
