Usage

From source file:com.n2hsu.launcher.Page.java

public void onFlingToDelete(PointF vel) {
    final long startTime = AnimationUtils.currentAnimationTimeMillis();

    // NOTE: Because it takes time for the first frame of animation to
    // actually be
    // called and we expect the animation to be a continuation of the fling,
    // we have/*  w  w w.j av a2  s  .  com*/
    // to account for the time that has elapsed since the fling finished.
    // And since
    // we don't have a startDelay, we will always get call to update when we
    // call
    // start() (which we want to ignore).
