有两种用法，我的通常写在代码中，像下面这样： 

/**
     * Layout动画
     *
     * @return
     */
    protected LayoutAnimationController getAnimationController() {
        int duration=300;
        AnimationSet set = new AnimationSet(true);

        Animation animation = new AlphaAnimation(0.0f, 1.0f);
        animation.setDuration(duration);
        set.addAnimation(animation);

        animation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.0f,
                Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
                -1.0f, Animation.RELATIVE_TO_SELF, 0.0f);
        animation.setDuration(duration);
        set.addAnimation(animation);

        LayoutAnimationController controller = new LayoutAnimationController(set, 0.5f);
        controller.setOrder(LayoutAnimationController.ORDER_NORMAL);
        return controller;
    }

应用的时候只需这样： 

listView = (ListView) findViewById(R.id.listView);
listView.setLayoutAnimation(getAnimationController());
adapter = new ListViewAdapter(stores);
listView.setAdapter(adapter);

这样一个简单的LayoutAnimation就完成了。 

别看到这里就以为文章就完了，以上都是些小玩意。呵呵，还有更厉害的！ 

你想设置更炫的动画吗？LayoutAnimation通常是Item一个一个的出现，有某种规律的。想让每个Item都有自己的动画吗？那就继续看下去。 

.......
private int duration=1000;
        private Animation push_left_in,push_right_in;
        private Animation slide_top_to_bottom,slide_bottom_to_top;
        public ListViewAdapter(ArrayList<Store> list) {
            this.list = list;
            push_left_in=AnimationUtils.loadAnimation(context, R.anim.push_left_in);
            push_right_in=AnimationUtils.loadAnimation(context, R.anim.push_right_in);
            slide_top_to_bottom=AnimationUtils.loadAnimation(context, R.anim.slide_top_to_bottom);
            slide_bottom_to_top=AnimationUtils.loadAnimation(context, R.anim.slide_bottom_to_top);
        }
........

@Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            ViewHodler hodler;
            if (convertView == null) {
                hodler = new ViewHodler();
                convertView = LayoutInflater.from(context).inflate(
                        R.layout.simple_item_7_for_main, null);
                ........


                convertView.setTag(hodler);

                if (position % 2 == 0) {
                    push_left_in.setDuration(duration);
                    convertView.setAnimation(push_left_in);
                } else {
                    push_right_in.setDuration(duration);
                    convertView.setAnimation(push_right_in);
                }

                /*if(position==0){
                    slide_bottom_to_top.setDuration(duration);
                    convertView.setAnimation(slide_bottom_to_top);
                }
                else{
                    slide_top_to_bottom.setDuration(duration);
                    convertView.setAnimation(slide_top_to_bottom);
                }*/

            }else{
                hodler = (ViewHodler) convertView.getTag();
            }
........


            return convertView;
        }

看见上面的动画设置了吗？将动画写在getView()中，这样可以设置很多不同的动画。其实这不属于LayoutAnimation的范畴了。 

你可以试一下，如果设计好的话，可以有比LayoutAnimation更酷的效果。 

我这里只试了两种效果。 

下面是我的动画文件，共四个： 

第一种效果：item分别从左右两侧滑入效果。 

push_left_in.xml 

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="-100%p" android:toXDelta="0" android:duration="300"/>
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

push_right_in.xml 

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="100%p" android:toXDelta="0" android:duration="300"/>
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

第2种效果：第一个item从下往上滑入，其他Item从上往下滑入效果，这个效果如果单个Item比较高（height）的话效果非常酷（卡牛的老版本好像用的就是这种效果）。 

slide_bottom_to_top.xml 

<?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:fromYDelta="100%" android:toXDelta="0" android:duration="300" />
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

slide_top_to_bottom.xml 

<?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:fromYDelta="-100%" android:toXDelta="0" android:duration="300" />
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />
</set>

另外一篇： 

这个不是我写的。 

GridView的item从上下左右飞入
