你可以使用 view animation system 對一個view實現補間動畫. 

A tween animation can perform a series of simple transformations (position, size, rotation, and transparency) on the contents of a View object.. The provides all the classes used in a tween animation.

 補間動畫能夠對一個view執行一系列的轉置操作，比如位置，大小旋轉和移動，animation package

A sequence of animation instructions defines the tween animation, defined by either XML or Android code. As with defining a layout, an XML file is recommended because it's more readable, reusable, and swappable than hard-coding the animation. In the example below, we use XML. (To learn more about defining an animation in your application code, instead of XML, refer to the

 定義補間動畫的一系列指令可以是XML,也可以是Android程式碼，不過首選XML檔案的方式

The animation instructions define the transformations that you want to occur, when they will occur, and how long they should take to apply. Transformations can be sequential or simultaneous - for example, you can have the contents of a TextView move from left to right, and then rotate 180 degrees, or you can have the text move and rotate simultaneously. Each transformation takes a set of parameters specific for that transformation (starting size and ending size for size change, starting angle and ending angle for rotation, and so on), and also a set of common parameters (for instance, start time and duration).To make several transformations happen simultaneously, give them the same start time; to make them sequential, calculate the start time plus the duration of the preceding transformation.

動畫指令定義了動畫何時發生和持續的時間。一個轉置可以順序執行，也可以同時執行，例如你可以讓一個TextView先從左移到右，再旋轉180度，也可以讓移動和旋轉同時發生

The animation XML file belongs in theres/anim/directory of your Android project. The file must have a single root element: this will be either a single<alpha>,<scale>,<translate>, <rotate>, interpolator element, or<set>element that holds groups of these elements (which may include another<set>).By default, all animation instructions are applied simultaneously. To make them occur sequentially, you must specify thestartOffsetattribute, as shown in the example below.

animation的xml檔案放在 專案的res/anim/目錄下，這些檔案必須有一個<alpha>, <scale>,<translate>, <rotate>, interpolator element, or <set> 這樣的根元素，

切指令是同時執行的，要想順序執行的話，必須設定startOffset

The following XML from one of the ApiDemos is used to stretch, then simultaneously spin and rotate a View object.

<set android:shareInterpolator="false">
    <scale
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:fromXScale="1.0"
        android:toXScale="1.4"
        android:fromYScale="1.0"
        android:toYScale="0.6"
        android:pivotX="50%"
        android:pivotY="50%"
        android:fillAfter="false"
        android:duration="700" />
    <set android:interpolator="@android:anim/decelerate_interpolator">
        <scale
           android:fromXScale="1.4"
           android:toXScale="0.0"
           android:fromYScale="0.6"
           android:toYScale="0.0"
           android:pivotX="50%"
           android:pivotY="50%"
           android:startOffset="700"
           android:duration="400"
           android:fillBefore="false" />
        <rotate
           android:fromDegrees="0"
           android:toDegrees="-45"
           android:toYScale="0.0"
           android:pivotX="50%"
           android:pivotY="50%"
           android:startOffset="700"
           android:duration="400" />
    </set>
</set>

螢幕的座標是左上角的（0,0），然後向下和向右擴充套件

Screen coordinates (not used in this example) are (0,0) at the upper left hand corner, and increase as you go down and to the right.

pivotX：50代表相對於父view,50%相對於自己

Some values, such as pivotX, can be specified relative to the object itself or relative to the parent. Be sure to use the proper format for what you want ("50" for 50% relative to the parent, or "50%" for 50% relative to itself).

You can determine how a transformation is applied over time by assigning an . Android includes several Interpolator subclasses that specify various speed curves: for instance, tells a transformation to start slow and speed up. Each one has an attribute value that can be applied in the XML.

With this XML saved as hyperspace_jump.xml in the res/anim/ directory of the project, the following code will reference it and apply it to anImageView object from the layout.

ImageView spaceshipImage = (ImageView) findViewById(R.id.spaceshipImage);
Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(this, R.anim.hyperspace_jump);
spaceshipImage.startAnimation(hyperspaceJumpAnimation);

As an alternative to startAnimation(), you can define a starting time for the animation withAnimation.setStartTime(), then assign the animation to the View with.

For more information on the XML syntax, available tags and attributes, see Animation Resources.

Note: Regardless of how your animation may move or resize, the bounds of the View that holds your animation will not automatically adjust to accommodate it. Even so, the animation will still be drawn beyond the bounds of its View and will not be clipped. However, clipping will occur if the animation exceeds the bounds of the parent View.
