Question 1

Which method begins the movement in a Frame animation?
A) move()
B) start()
C) animate()
D) begin()

Accepted Answer

The "start()" method begins the movement in a Frame animation. This method initiates the animation by starting the animation timer, causing the "actionPerformed()" method to be repeatedly executed which updates the frame being drawn. The other methods listed are not relevant to starting a Frame animation.

Question 2

Applying the Tween rotation animation, which of the following methods begins animating a View object by calling the AnimationUtils class utilities to access the resources necessary to load the animation?
A) viewAnimation
B) getAnimation
C) newAnimation
D) startAnimation

Accepted Answer

The correct method to begin animating a View object by utilizing the AnimationUtils class to load the animation resources is `startAnimation`. This method is called on a View object to apply an animation defined in XML and loaded using AnimationUtils.

Question 3

In Android development, what are frame-based animations and image transitions defined as?
A) instances
B) images
C) drawables
D) objects

Accepted Answer

Frame-based animations and image transitions are typically defined as drawables in Android development. Drawables are resources that can be used for visual elements such as images, icons, and animations.

Question 4

By what method are drawable images in an animation-list connected to an instance of an ImageView object ?
A) getBackgroundResource
B) setBackgroundImage
C) getBackgroundReference
D) setBackgroundResource

Accepted Answer

The method used to connect the drawable images in an animation-list to an instance of an ImageView object is setBackgroundResource(). This method sets the background resource for the ImageView to the specified drawable resource. Therefore, the correct choice is D.

Question 5

What do button controls use to await user interaction?
A) getButton
B) setOnClickListener
C) btnStart
D) btTween

Accepted Answer

Button controls use the setOnClickListener method to await user interaction. The other options listed (getButton, btnStart, btTween) are not commonly used methods for button controls.

Question 6

When the XML file is added to the Android project, the Android resource type is selected and animation-list is specified as which element of the XML code?
A) main
B) first
C) last
D) root

Accepted Answer

The root element of an XML file is the top-level element that encloses all other elements. In this case, the root element of the animation-list XML code defines the entire animation sequence. Therefore, selecting the Android resource type and specifying the animation-list as the root element is the correct choice.

Question 7

Which of the following terms best describes a transition that changes objects from one state to another?
A) tween effect
B) animation
C) animation-list
D) emulator

Accepted Answer

Tween effect is a term used in animation to describe the process of transitioning objects from one state to another, often by interpolating between keyframes.

Question 9

Which statement correctly completes the following code to begin a Tween rotation animation? imgRotate.startAnimation(AnimationUtils.loadAnimation ...
A) (this, R.anim.rotation));
B) .rotation( this.R.anim ));
C) ( R.anim.rotation , this));
D) .R.anim( rotation, this));

Accepted Answer

Option A correctly completes the code by passing the context and the rotation animation from the resources folder using R.anim.rotation.

Question 11

Which statement launches an intent to start an activity named Tween?
A) startIntent (new Intent (MainActivity.this, Tween.class));
B) startActivity (new Intent (MainActivity.this, Tween.class));
C) startActivity (new Activity (MainActivity.this, Tween.class));
D) startIntent (new Activity (MainActivity.this, Tween.class));

Accepted Answer

To start an activity, we use the startActivity method and pass an Intent object as a parameter that specifies the activity to be launched. The correct syntax for this is startActivity(new Intent(context, activityToLaunch.class)). Therefore, option B is the correct choice. Option A uses the incorrect method name "startIntent" instead of "startActivity". Option C uses the incorrect constructor "new Activity" instead of "new Intent" and Option D uses the incorrect constructor for the Intent object, which should be "new Intent" not "new Activity".

Question 12

A(n) ____________________ specifies a start state of an object, and then animates the object using a uniform transition type such as rotating a predetermined number of times or an infinite number of times.

Question 15

Which of the following provides the methods for drawable animations to create a sequence of frame-by-frame images?
A) AnimatedGraphic constructor
B) AnimationList class
C) AnimationDrawable class
D) startAnimation constructor

Accepted Answer

The AnimationDrawable class provides the methods for drawable animations to create a sequence of frame-by-frame images. The other options (AnimatedGraphic constructor, AnimationList class, and startAnimation constructor) do not have this specific functionality.

Question 16

What has predefined "stretching" areas that maintain the same look on different screen sizes?
A) 9-patch image
B) animation-list
C) ImageView
D) AnimationDrawable

Accepted Answer

9-patch images allow for predefined stretching areas that maintains the same look on different screen sizes.

Question 17

Which statement completes the following code to instantiate the ImageView control named imgTween? ImageView imgRotate = (ImageView) ...
A) findViewById(R.id.imgTween);
B) findViewById(id.imgTween);
C) findViewById(imgTween);
D) findViewById(R.imgTween.id);

Accepted Answer

The correct syntax to instantiate a control using findViewById is findViewById(R.id.controlName), where "controlName" is the ID of the control in the XML layout file. Therefore, the correct answer is A.

Question 18

What property of an image can be set to any full Drawable resource such as a . P n g file, a 9-patch image file, or a solid color designated with hexadecimal code such as #FF0000?
A) Background
B) Theme
C) layoutMode
D) transitionName

Accepted Answer

The property that can be set to any full Drawable resource such as a .Png file, a 9-patch image file, or a solid color designated with hexadecimal code such as #FF0000 is the background property. It can be set for any View or ViewGroup in Android. The background can be set using XML or in code.

A) 3DGraphics
B) AnimationGraphics
C) GraphicsLibrary
D) OpenGL

Accepted Answer

OpenGL is a widely used cross-platform graphics API that specifies a standard software interface for 3D graphics processing hardware and uses a coordinate system to map the image to the screen. While the other options (A, B, and C) may be related to graphics in general, they do not specifically describe a cross-platform graphics API or mention the use of a coordinate system for mapping images to the screen.
