Let me summarize everythign I have learned so far with an example
I wills start with a picture of what I am trying to animate and using what aspects of property animations
Property Animations
satya - Monday, November 07, 2011 9:54:22 AM
Start with an animator
ValueAnimator anim = ValueAnimator.ofFloat(0f, 1f);
anim.setDuration(500);
anim.start();
satya - Monday, November 07, 2011 9:55:15 AM
Provide a callback impl
anim.addUpdateListener(
new ValueAnimator.AnimatorUpdateListener()
{
public void onAnimationUpdate(ValueAnimator animation)
{
Float value = (Float) animation.getAnimatedValue();
// do something with value...
}
}
);

Here is how you can change the alpha of a text view
private void animateTextView(TextView tv)
{
//Fade out if it is visible, making it invisible
if (tv.getAlpha() != 0)
{
ObjectAnimator fadeOut =
ObjectAnimator.ofFloat(m_tv, "alpha", 0f);
fadeOut.start();
}
//Fade in if it is invisible, makign it visible
else
{
ObjectAnimator fadeIn =
ObjectAnimator.ofFloat(m_tv, "alpha", 1f);
fadeIn.start();
}
}

AnimatorSet is an Animator by itself
So chaining is possible
satya - Tuesday, November 08, 2011 1:39:42 PM
What is AnimatorSet.Builder?
This is purely a utility class that allows you establish reslationship between the individual animations in a set. Whether to run the animations serially, parallely or to run before or to run after etc.
if you can do this relationships with the animator set itself explicitly then you can use it as such.

as.play(fadeOut).before(fadeIn);
as.setDuration(2000); //2 secs
as.start();
}
satya - Tuesday, November 08, 2011 1:46:59 PM
Note worthy
You start with a single animator
you will use "play" against that single animator to start the builder. This first animator becomes the animator of focus. All subsequent animations used by
before after with
are in relation to the first animator.
In the end you start the animator set and not the builder. The duration and interpolators etc also apply to the animator set and animators and not to the builder.

ObjectAnimator.ofFloat(m_tv, 'alpha', 0f, 1f, 2f, ....)
Constructs and returns an ObjectAnimator that animates between int values. A single value implies that that value is the one being animated to. Two values imply a starting and ending values. More than two values imply a starting value, values to animate through along the way, and an ending value (these values will be distributed evenly across the duration of the animation).

satya - Tuesday, November 08, 2011 3:25:26 PM
what can you tell about the view property animator
it is instigated by calling "animate()" on any view
The sets on the view property animator are cumulative for this frame: that is a bit similar to OpenGL if I remember right
All the animations are clubbed and played when the UI thread gets around to it on subsequent frame refreshes

Remember that a last linear layout may take all the space?
Unless you pay attention and control the height of the linear layout it may take the entire space left in the activity if it is the last one. To control it otherwise use the wrap_content options for height instead of match or fill parent.
satya - Wednesday, November 09, 2011 2:48:43 PM
Here is a way you can animate a view using points
public class MyAnimatableView
{
PointF curPoint = null;
View m_v = null;
public MyAnimatableView(View v)
{
curPoint = new PointF(v.getX(),v.getY());
m_v = v;
}
public PointF getCurPointF()
{
return curPoint;
}
public void setPoint(PointF p)
{
curPoint = p;
m_v.setX(p.x);
m_v.setY(p.y);
}
}
satya - Wednesday, November 09, 2011 2:59:10 PM
idea is....
Keep a local pointer to a view such as a text view. Keep this parent object in your activity as a local variable.
Have a set method on the view that can change what you want to change such as the position of the view.
All you have to do now is to find a mechanism to invoke "setPoint" frequently.
This can be done by an object animator
Pass the object animator this object, and the name of the method and the startign point and the ending point.
This is done through object animators adn type evaluators. Here is the driver code for this first and then I will show you the type evaluator that knows to vary points over time
satya - Wednesday, November 09, 2011 3:00:59 PM
Here is how you would use a type evaluator with an object animator
public void testTypeEvaluator(TextView m_tv,
MyAnimatableView m_atv)
{
m_tv.setAlpha(1f);
float h = m_tv.getHeight();
float w = m_tv.getWidth();
float x = m_tv.getX();
float y = m_tv.getY();
ObjectAnimator tea =
ObjectAnimator.ofObject(m_atv
,"point"
,new MyPointEvaluator()
,new PointF(w,h)
,new PointF(x,y));
tea.setDuration(5000);
tea.start();
}
satya - Wednesday, November 09, 2011 3:01:43 PM
Here is the code for the MyPointEvaluator
public class MyPointEvaluator
implements TypeEvaluator<PointF>
{
public PointF evaluate(float fraction,
PointF startValue,
PointF endValue)
{
PointF startPoint = (PointF) startValue;
PointF endPoint = (PointF) endValue;
return new PointF(
startPoint.x + fraction * (endPoint.x - startPoint.x),
startPoint.y + fraction * (endPoint.y - startPoint.y));
}
}

Let me summarize the layout transistions
To enable layout transitions on a view group you will do
viewgroup.setLayoutTransition( new LayoutTransition() );
satya - Thursday, November 10, 2011 9:07:00 AM
The layouttransition object comes with its own set of 4 animators
The layout transistion comes with its own set of 4 animators for each of the 4 transitions.
satya - Thursday, November 10, 2011 9:09:33 AM
The transitions are
add a view (appearing)
change appearing (rest of the items in layout)
remove a view (disappearing)
change disappearing (rest of the items in layout)
satya - Thursday, November 10, 2011 9:17:54 AM
Couple of useful methods
LayoutTransition lt
= new LayoutTransition();
someLayout.setLayoutTransition(lt);
//obtain a default animator if you
//need to remember
Animator defaultAppearAnimator
= lt.getAnimator(APPEARING);
//create a new animator
ObjectAnimator someNewObjectAnimator;
//set it as your custom animator
lt.setAnimator(someNewObjectAnimator);
satya - Thursday, November 10, 2011 9:18:54 AM
Animator templates in layout transitions
Because the animator you supply to a layout transition applies to each view, they get internally cloned before being applied to each view.

satya - Thursday, November 10, 2011 9:30:15 AM
In this demo I have used
An object animator to fade out and fade in individually
An object animator to fade out and fade in sequentially
Use an object animator builder to tie multiple animations together
in a relationship.
Use XML to load an animation from a resource file
Use Property Values Holder to animate multiple values
Use view property animator to optimize view animation
Use a type evaluator to move an object in 2 dimensions
Use key frames for checkered progress

Couple of words about this layout
There are just a series of buttons that are tied to functions.
The text view is ensconced in a second linear layout because this will allow me to set the "x" and "y" values with respect to this layouts position that excludes the buttons. Otherwise the "x" and "y" values will be that of the bigger parent.
