ViewFlipper animation
<p>I have a <code>ViewFlipper</code> which contains two layouts. These two layouts helds just one <code>ImageView</code> each. There is an animation when I scroll between these two layouts, but the animation isn't triggerd before I lift my finger, this happens because of this:</p>

<pre><code>   case MotionEvent.ACTION_UP:
   //do animation
</code></pre>

<p>How can I modify my code so the animation is triggerd when I held my finger and slide left to right and vice verca? </p>

<p>Codesnippet for doing the animation:</p>

<pre><code> @Override
    public boolean onTouchEvent(MotionEvent touchevent) {
        switch (touchevent.getAction())
        {
            case MotionEvent.ACTION_DOWN:
            {
                oldTouchValue = touchevent.getX();
                break;
            }
            case MotionEvent.ACTION_UP:
            {
                //if(this.searchOk==false) return false;
                float currentX = touchevent.getX();
                if (oldTouchValue &lt; currentX)
                {
                   vf.setInAnimation(inFromLeftAnimation());
                   vf.setOutAnimation(outToRightAnimation());
                    vf.showNext();
                }
                if (oldTouchValue &gt; currentX)
                {

            break;
            }
        }
        return false;
    }
