apidemo还是有非常多的好东西的作为初学者必须看啊

首先是一个一个叠下来的动画

很简单 gridview中的:

android:layoutAnimation="@anim/layout_grid_fade"

<?xml version="1.0" encoding="utf-8"?>
<gridLayoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
    android:animation="@anim/fade"
    android:directionPriority="column"
    android:rowDelay="50%" />

fade

<?xml version="1.0" encoding="utf-8"?>
<gridLayoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
    android:animation="@anim/fade"
    android:directionPriority="column"
    android:rowDelay="50%" />

然后是listview 的从上面甩下来:

AnimationSet set = new AnimationSet(true);

        Animation animation = new AlphaAnimation(0.0f, 1.0f);
        animation.setDuration(50);
        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(100);
        set.addAnimation(animation);

        LayoutAnimationController controller = new LayoutAnimationController(set, 0.5f);
        ListView listView = getListView();        
        listView.setLayoutAnimation(controller);

向上甩上去

演示用用xml实现

android:layoutAnimation="@anim/layout_bottom_to_top_slide"

<?xml version="1.0" encoding="utf-8"?>
<layoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
    android:animation="@anim/slide_right"
    android:animationOrder="reverse"
    android:delay="30%" />

slide_right

<?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="-100%p" android:toXDelta="0"
            android:duration="@android:integer/config_shortAnimTime" />
</set>

GridView 随机显示item

android:layoutAnimation="@anim/layout_random_fade"

<?xml version="1.0" encoding="utf-8"?>

<layoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
        android:delay="0.5"
        android:animationOrder="random"
        android:animation="@anim/fade" />

fade

<?xml version="1.0" encoding="utf-8"?>
<gridLayoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
    android:animation="@anim/fade"
    android:directionPriority="column"
    android:rowDelay="50%" />

从下到上的显示item

<?xml version="1.0" encoding="utf-8"?>

<gridLayoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
        android:columnDelay="0.5"
        android:directionPriority="row"
        android:direction="right_to_left|bottom_to_top"
        android:animation="@anim/fade" />

其他两个感觉不是很好不介绍了
