<set xmlns:android="http://schemas.android.com/apk/res/android"    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/accelerate_interpolator"        android:startOffset="700">        <scale            android:fromXScale="1.4"            android:toXScale="0.0"            android:fromYScale="0.6"            android:toYScale="0.0"            android:pivotX="50%"            android:pivotY="50%"            android:duration="400" />        <rotate            android:fromDegrees="0"            android:toDegrees="-45"            android:toYScale="0.0"            android:pivotX="50%"            android:pivotY="50%"            android:duration="400" />    </set></set>

This application code will apply the animation to an ImageView and start the animation（这个应用程序代码将动画应用于ImageView并启动动画）:

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