    copied!<p>As in the documented said</p> <p><a href="http://developer.android.com/reference/android/widget/ScrollView.html" rel="nofollow noreferrer">http://developer.android.com/reference/android/widget/ScrollView.html</a></p> <blockquote> <p>ScrollView only supports vertical scrolling. For horizontal scrolling, use HorizontalScrollView.</p> </blockquote> <p>So, I need to ask why did you really want to use your custom scrollview?</p> <p>If you only intend to be able to scroll, you might no need to use it</p> <p>only RelativeLayout.scrollBy(x,y); is enough</p> <p>You could look at this link</p> <p><a href="https://stackoverflow.com/questions/2044775/scrollview-vertical-and-horizontal-in-android">Scrollview vertical and horizontal in android</a></p> <h1>EDIT</h1> <p>Ok, So you need to make the gesture detect the fling over the ScrollView.</p> <p>You could make it in your Activity without making custom ScrollView also</p> <p>first, you need to </p> <pre><code>implements OnGestureListener, OnTouchListener, GestureDetector.OnDoubleTapListener </code></pre> <p>and in your class create gestureDetector</p> <pre><code>gd = new GestureDetector(this); </code></pre> <p>and your ScrollView object, just declared </p> <pre><code>sv.setOnTouchListener(this); </code></pre> <p>then, in override onTouch method</p> <pre><code>@Override public boolean onTouch(View v, MotionEvent event) { onTouchEvent(event); // throw to onTouchEvent return false; } </code></pre> <p>and in override onTouchEvent method</p> <pre><code>@Override public boolean onTouchEvent(MotionEvent me) { return gd.onTouchEvent(me); // gd = gesturedetector } </code></pre> <p>now override your onFling method like this</p> <pre><code>private static final int SWIPE_MIN_DISTANCE = 120; private static final int SWIPE_THRESHOLD_VELOCITY = 200; @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { if(e1.getX() - e2.getX() &gt; SWIPE_MIN_DISTANCE &amp;&amp; Math.abs(velocityX) &gt; SWIPE_THRESHOLD_VELOCITY) { // "Left Swipe" vf.showPrevious(); // vf = ViewFlipper } else if (e2.getX() - e1.getX() &gt; SWIPE_MIN_DISTANCE &amp;&amp; Math.abs(velocityX) &gt;
