    <p>Here is how I solved the problem. Hope this helps.</p> <pre><code>// declare class member variables private GestureDetector mGestureDetector; private OnTouchListener mGestureListener; private boolean mIsScrolling = false; public void initGestureDetection() { // Gesture detection mGestureDetector = new GestureDetector(new SimpleOnGestureListener() { @Override public boolean onDoubleTap(MotionEvent e) { handleDoubleTap(e); return true; } @Override public boolean onSingleTapConfirmed(MotionEvent e) { handleSingleTap(e); return true; } @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { // i'm only scrolling along the X axis mIsScrolling = true; handleScroll(Math.round((e2.getX() - e1.getX()))); return true; } @Override /** * Don't know why but we need to intercept this guy and return true so that the other gestures are handled. * https://code.google.com/p/android/issues/detail?id=8233 */ public boolean onDown(MotionEvent e) { Log.d("GestureDetector --&gt; onDown"); return true; } }); mGestureListener = new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (mGestureDetector.onTouchEvent(event)) { return true; } if(event.getAction() == MotionEvent.ACTION_UP) { if(mIsScrolling ) { Log.d("OnTouchListener --&gt; onTouch ACTION_UP"); mIsScrolling = false; handleScrollFinished(); }; } return false; } }; // attach the OnTouchListener to the image view mImageView.setOnTouchListener(mGestureListener); } </code></pre>

    1. COThanks for your help. Judging by the thread on Google Code Android, which your link refers to, there seems to be some confusion about the consequences of returning "true" or "false". I'll try "return true" in the onDown method and shall report back.

    2. COThank you very much indeed for this code. It seems to be the answer to my problem. I thought at first the crucial line in your code was "return true" in the onDown method, but in fact this seems to make no difference in my code. The key point seems to be that, so far as I can see, the GestureDetector is never notified of an ACTION_UP event, so as (you correctly identified) I have to include code in my onTouchListener.onTouch() method to look out for this event at the end of the scroll. Thanks again!

    3. COInteresting... and very helpful. But in a quick test I seem to be getting a touch-up event before a fling. I want to do different things if a fling is occurring or scrolling has simply stopped. When I detect a touch-up, how do I know if I'm about to get a fling event so that I won't perform my normal scroll-end functionality?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
