title: Scrollview zoom not scrolling left and right
body: <p>I'm trying to make the ScrollView zoom-able following this <a href="https://stackoverflow.com/a/19628186/4196092">post</a> </p>
  
  <pre><code> mScaleDetector = new ScaleGestureDetector(context,
       new ScaleGestureDetector.SimpleOnScaleGestureListener() {
       @Override
       public boolean onScale(ScaleGestureDetector detector) {
       float scale = 1 - detector.getScaleFactor();
  
       float prevScale = mScale;
       mScale += scale;
  
       if (mScale &lt; 0.1f) // Minimum scale condition:
       mScale = 0.1f;
  
       if (mScale &gt; 10f) // Maximum scale condition:
       mScale = 10f;
       ScaleAnimation scaleAnimation = new ScaleAnimation(
       1f / prevScale, 1f / mScale, 1f / prevScale,
       1f / mScale, detector.getFocusX(),
       detector.getFocusY());
       scaleAnimation.setDuration(0);
       scaleAnimation.setFillAfter(true);
  
       startAnimation(scaleAnimation);
       return true;
       }
  
  
       });
  </code></pre>
  
  <p>but the zooming scrolls only work up and down, i'm trying to make it scroll left and right too.</p>
