mainXML:

[html]

        <!-- 專輯圖片 --> 
 
        <ImageView 
            android:id="@+id/player_image" 
            android:layout_width="fill_parent" 
            android:layout_height="fill_parent" 
            android:layout_centerInParent="true" 
            android:src="@drawable/player_image" 
            android:text="專輯" /> 
        <!-- 播放 --> 
 
        <ImageView 
            android:id="@+id/player_play" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content"

        <!-- 上一曲 -->

            android:paddingRight="10dp" 
            android:paddingTop="10dp" 
            android:src="@drawable/player_shuffle_off" /> 
        <!-- 左上順序播放 --> 
 
        <ImageView 
            android:id="@+id/player_repeat" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:layout_alignParentLeft="true" 
            android:paddingLeft="10dp" 
            android:paddingTop="10dp" 
            android:src="@drawable/player_repeat_off" /> 
    </RelativeLayout> 
 
</RelativeLayout> 

動畫效果類似,只貼一個實例:

[html]
<?xml version="1.0" encoding="utf-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android" > 
 
    <alpha 
        android:duration="2500" 
        android:fromAlpha="1.0" 
        android:toAlpha="0.0" /> 
 
    <translate 
        android:duration="2500" 
        android:fromXDelta="0%p" 
        android:fromYDelta="0%p" 
        android:toXDelta="-800%p" 
        android:toYDelta="0%p" /> 
 
    <!-- 
         <scale 
        android:duration="3000" 
        android:fillAfter="true" 
        android:fromXScale="0" 
        android:fromYScale="0" 
        android:toXScale="1.0" 
        android:toYScale="1.0" /> 
 
 
 
 
 
    --> 
 
</set> 

效果:所有控件向中心收縮滑動後消失,點擊專輯封面重新顯示
