android:toAlpha     动画结束的透明度 0---1 从透明到不透明

Float. Ending opacity offset, where 0.0 is transparent and 1.0 is opaque.

<translate>

android:fromXDelta  起始点X坐标

Float or percentage. Starting X offset. Expressed either: in pixels relative to the normal position (such as "5"), in percentage relative to the element width (such as "5%"), or in percentage relative to the parent width (such as "5%p").

android:toXDelta  结束点X坐标

Float or percentage. Ending X offset. Expressed either: in pixels relative to the normal position (such as "5"), in percentage relative to the element width (such as "5%"), or in percentage relative to the parent width (such as "5%p").

android:fromYDelta   起始点Y坐标

Float or percentage. Starting Y offset. Expressed either: in pixels relative to the normal position (such as "5"), in percentage relative to the element height (such as "5%"), or in percentage relative to the parent height (such as "5%p").

android:toYDelta  结束点X坐标

Float or percentage. Ending Y offset. Expressed either: in pixels relative to the normal position (such as "5"), in percentage relative to the element height (such as "5%"), or in percentage relative to the parent height (such as "5%p").

<rotate>

android:fromDegrees  开始旋转的角度位置，正数是顺时针，负数是逆时针

Float. Starting angular position, in degrees.

android:toDegrees  结束旋转到的角度

Float. Ending angular position, in degrees.

android:pivotX    旋转的X坐标

Float or percentage. The X coordinate of the center of rotation. Expressed either: in pixels relative to the object's left edge(suchas "5"), in percentage relative to the object's left edge (such as "5%"), or in percentage relative to the parent container's left edge(such as "5%p").

android:pivotY  旋转的Y坐标

Float or percentage. The Y coordinate of the center of rotation. Expressed either: in pixels relative to the object's topedge(suchas "5"),in percentage relative to the object's top edge (such as "5%"), or in percentage relative to the parent container's topedge (suchas "5%p").

Frame animation

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"android:oneshot=["true" | "false"] ><itemandroid:drawable="@[package:]drawable/drawable_resource_name"android:duration="integer" />
</animation-list>

<animation-list> Required. This must be the root element. Contains one or more <item> elements.

attributes:     android:oneshot   Boolean.  "true" if you want to perform the animation once; "false" to loop the animation.

<item> A single frame of animation. Must be a child of a <animation-list> element.attributes:

android:drawable Drawable resource. The drawable to use for this frame.

android:duration     Integer. The duration to show this frame, in milliseconds.

官方EXAMPLE

res/drawable/rocket.xml:

?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"android:oneshot="false"><item android:drawable="@drawable/rocket_thrust1" android:duration="200" /><item android:drawable="@drawable/rocket_thrust2" android:duration="200" /><item android:drawable="@drawable/rocket_thrust3" android:duration="200" />
</animation-list>
