1>在res目录下要创建anim文件夹在这个文件夹下要创建如下xml ：alpha_anim.xml，group_anim.xml，rotate_anim.xml，scale_anim.xml，translate_anim.xml。

2>四个xml文件对应的代码如下

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
    android:fromAlpha="0.1"
  android:toAlpha="1.0"
  android:duration="5000"
/>
</set>

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate
  android:fromXDelta="0"
  android:fromYDelta="0"
  android:toXDelta="400"
  android:toYDelta="0"
  android:duration="6000"
/>
<rotate
android:fromDegrees="0"
android:toDegrees="+359"
android:pivotX="50%"
android:pivotY="50%"
android:duration="2000"
android:repeatCount="2"
/>

</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate
  android:fromXDelta="0"
  android:fromYDelta="0"
  android:toXDelta="400"
  android:toYDelta="0"
  android:duration="6000"
/>
<rotate
android:fromDegrees="0"
android:toDegrees="+359"
android:pivotX="50%"
android:pivotY="50%"
android:duration="2000"
android:repeatCount="2"
/>

</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<rotate
android:fromDegrees="0"
android:toDegrees="+360"
android:pivotX="50%"
android:pivotY="50%"
android:duration="2000"
android:repeatCount="2"
/>
</set>

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale
  android:fromXScale="0.0"
  android:fromYScale="0.0"
  android:toXScale="1.0"
  android:toYScale="1.0"
  android:pivotX="50%"
  android:pivotY="50%"
  android:repeatCount="2"
  android:duration="2000"
/>
</set>

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
  android:interpolator="@android:anim/accelerate_interpolator"
  android:fromXDelta="0"
  android:fromYDelta="0"
  android:toXDelta="400"
  android:toYDelta="0"
  android:repeatCount="2"
  android:duration="5000"
/>


</set>

3>自己在准备一张图片放在res的drawable文件夹下，名字和上面定义的致就行。

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
    android:fromAlpha="0.1"
  android:toAlpha="1.0"
  android:duration="5000"
/>
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
    android:fromAlpha="0.1"
  android:toAlpha="1.0"
  android:duration="5000"
/>
</set>
4>这个activity用到的布局文件如下

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_gravity="center_vertical"
    android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/anim_test_img"
/>
<Button
android:layout_marginTop="50.0dp"
android:layout_marginLeft="100.0dp"
    android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Alpha Animation"
android:id="@+id/anim_test_btn01"
/>
<Button
android:layout_marginTop="50.0dp"
android:layout_marginLeft="100.0dp"
    android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Scale Animation"
android:id="@+id/anim_test_btn02"
/>
<Button
android:layout_marginTop="50.0dp"
android:layout_marginLeft="100.0dp"
    android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TranslateAnimation"
android:id="@+id/anim_test_btn03"
/>
<Button
android:layout_marginTop="50.0dp"
android:layout_marginLeft="100.0dp"
    android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Rotate Animation"
android:id="@+id/anim_test_btn04"
/>
   <Button
    android:layout_marginTop="50.0dp"
   android:layout_marginLeft="100.0dp"
    android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Group \n Animation_1"
android:id="@+id/anim_test_btn05"
/>
</LinearLayout>
