<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/decelerate_interpolator" >
 
    <scale
        android:duration="1000"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="1.0"
        android:toYScale="1.0" />
 
    <alpha
        android:duration="2000"
        android:fromAlpha="0.0"

    <style name="PopupWindowAnimation" parent="android:Animation">
        <item name="android:windowEnterAnimation">@anim/enter</item>

    <Button
        android:id="@+id/open"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

    <color name="colorPopUpWindow">#000000</color>
