A. normal animation:
can be set by code or set by XML . Use animationSet and XXXanimation ,very easy:
package com.animation_test_02;
import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.animation.*;
import android.widget.Button;
import android.widget.ImageView;
public class AnimationTest02 extends Activity
{
/** Called when the activity is first created. */
private Button scaleBtn;
private Button rotateBtn;
private Button translateBtn;
private Button alphaBtn;
private Button animationSetBtn;
private ImageView imgView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

}
};
}
if use XML , new an anim folder in res
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator">
<translate
android:fromXDelta="50%"
android:toXDelta="100%"
android:fromYDelta="50%p"
android:toYDelta="50%p"
android:duration="2000"
/>
<alpha
android:fromAlpha="1"
android:toAlpha="0"
android:startOffset="500"
android:duration="500"
/>
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator"
android:shareInterpolator="true">
<alpha
android:fromAlpha="1"
android:toAlpha="0"
android:startOffset="500"
android:duration="500"
/>
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator">
<rotate
android:fromDegrees="0"
android:toDegrees="+350"
android:pivotX="50%"
android:pivotY="50%"
android:duration="3000"
/>
<!-- android:pivotX="50" absolute
android:pivotX="50%" child
android:pivotV="50%p" parent-->
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator">
<scale
android:fromXScale="1"
android:toXScale="0"
android:fromYScale="1"
android:toYScale="0"
android:pivotX="50%"
android:pivotY="50%"
android:duration="2000"
/>
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator">
<translate
android:fromXDelta="50%"
android:toXDelta="100%"
android:fromYDelta="50%p"
android:toYDelta="50%p"
android:duration="2000"
/>
</set>
B. much more important , the LayoutAnimation , LayoutAnimationCOntroller , and AnimationListener
1. if use XML to set layoutAnimation , no need to use LayoutAnimationController.
set an layoutAnimation,and indicate the animation set in it;
<?xml version="1.0" encoding="utf-8"?>
<layoutAnimation
xmlns:android="http://schemas.android.com/apk/res/android"
android:delay="0.5"
android:animationOrder="normal"
android:animation="@anim/list_anim"
/>
<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator"
android:shareInterpolator="true">
<alpha
android:fromAlpha="0"
android:toAlpha="1"
android:duration="2000"/>
</set>
2. iif use LayoutAnimationController, no need to indicate the layoutAnimation.xml in the res/anim
just new it in the code :
Animation animation=(Animation)AnimationUtils.loadAnimation(
AnimationTest03.this, R.anim.list_anim);
animation.setAnimationListener(animationListener);
//pass the animation item to the lac;
LayoutAnimationController lac=
new LayoutAnimationController(animation);
lac.setOrder(LayoutAnimationController.ORDER_NORMAL);
lac.setDelay(0.1f);
listView.setLayoutAnimation(lac);
note that how to convert an animationSet XML to an animation instance by AnimationUtils:
Animation animation=(Animation)AnimationUtils.loadAnimation(
AnimationTest03.this, R.anim.list_anim);
3. animationListener, very simple:
animation.setAnimationListener(animationListener);
Full Code:

//pass the animation item to the lac;
LayoutAnimationController lac=
new LayoutAnimationController(animation);
lac.setOrder(LayoutAnimationController.ORDER_NORMAL);
lac.setDelay(0.1f);
listView.setLayoutAnimation(lac);
}
};
private AnimationListener animationListener=new AnimationListener(){
public void onAnimationStart(Animation arg0) {
// throw new UnsupportedOperationException("Not supported yet.");
Log.i("l","animation start");
}

// listView.setAdapter(null);
Log.i("l","animation end");
Animation animation=(Animation)AnimationUtils.loadAnimation(
AnimationTest03.this, R.anim.list_anim);
animation.setAnimationListener(animationListener);
//pass the animation item to the lac;
LayoutAnimationController lac=
new LayoutAnimationController(animation);
lac.setOrder(LayoutAnimationController.ORDER_NORMAL);
lac.setDelay(0.1f);
listView.setLayoutAnimation(lac);
}
public void onAnimationRepeat(Animation arg0) {
// throw new UnsupportedOperationException("Not supported yet.");
Log.i("l","animation repeat");
}
};
private ListAdapter buildListAdapter(){
List<HashMap<String,String>> list=new

R.layout.item,
new String[]{"user_name","user_gender"},
new int[]{R.id.user_name,R.id.user_gender});
return simpleAdapter;
