XML中

alpha  ： 渐变透明度动画效果

scale  ：渐变尺寸伸缩动画效果

translate  ： 画面转换位置移动动画效果

rotate  ：画面转移旋转动画效果

Java代码中

AlphaAnimation  ： 渐变透明度动画效果

ScaleAnimation  ：渐变尺寸伸缩动画效果

TranslateAnimation  ： 画面转换位置移动动画效果

RotateAnimation  ：画面转移旋转动画效果

1、main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >
        <Button
            android:id="@+id/rotateButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="旋转" />
        <Button
            android:id="@+id/scaleButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="缩放" />
        <Button
            android:id="@+id/alphaButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="淡入淡出" />
        <Button
            android:id="@+id/translateButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="移动" />
    </LinearLayout>
    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >
        <ImageView
            android:id="@+id/image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:src="@drawable/an" />
</LinearLayout>
</LinearLayout>
