copied!<p>I think I found a simpler solution, only this uses a subclass of ViewPager instead of (its parent) ScrollView.</p> <p><strong>UPDATE 2013-07-16</strong>: I added an override for <code>onTouchEvent</code> as well. It could possibly help with the issues mentioned in the comments, although YMMV.</p> <pre><code>public class UninterceptableViewPager extends ViewPager { public UninterceptableViewPager(Context context, AttributeSet attrs) { super(context, attrs); } @Override public boolean onInterceptTouchEvent(MotionEvent ev) { boolean ret = super.onInterceptTouchEvent(ev); if (ret) getParent().requestDisallowInterceptTouchEvent(true); return ret; } @Override public boolean onTouchEvent(MotionEvent ev) { boolean ret = super.onTouchEvent(ev); if (ret) getParent().requestDisallowInterceptTouchEvent(true); return ret; } } </code></pre> <p>This is similar to <a href="https://android.googlesource.com/platform/frameworks/base/+/android-4.2.2_r1.2/core/java/android/widget/Gallery.java" rel="noreferrer">the technique used in android.widget.Gallery's onScroll()</a>. It is further explained by the Google I/O 2013 presentation <a href="http://www.youtube.com/watch?list=PLOU2XLYxmsIJOOTFfYzhR2d-rcSbBbEE&feature=player_detailpage&v=NYtB6mlu7vA#t=1950s" rel="noreferrer">Writing Custom Views for Android</a>.</p> <p><strong>Update 2013-12-10</strong>: A similar approach is also described in <a href="http://www.pushing-pixels.org/2011/03/01/android-bits-and-pieces-event-interception.html" rel="noreferrer">a post from Kirill Grouchnikov about the (then) Android Market app</a>.</p>
