    <p>I have a listview which I personalized and I added <code>setOnItemLongClickListener()</code> which worked well. Then I decided to implement a gesture <code>listView.setOnTouchListener(new OnSwipeTouchListener())</code> which also works well. I copied the <code>OnSwipetouchListener</code> class from another post.</p> <p>The thing is that when I added the swipe listener the longPress didn't work anymore. I guess it's because the swipe listener takes the longpress actions for itself and doesn't allow longPress to do anything.</p> <p>What I want to do:</p> <p>The swipe listener gets everything below 2 seconds, after that everything goes to longpress. So I can still change the listview content by a swipe gesture and I can also create functions for each listitem.</p> <p>My code:</p> <pre><code>public class OnSwipeTouchListener implements OnTouchListener { private final GestureDetector gestureDetector = new GestureDetector(new GestureListener()); public boolean onTouch(final View v, final MotionEvent event) { //super.onTouch(v, event); return gestureDetector.onTouchEvent(event); } private final class GestureListener extends SimpleOnGestureListener { private static final int SWIPE_THRESHOLD = 100; private static final int SWIPE_VELOCITY_THRESHOLD = 100; @Override public boolean onDown(MotionEvent e) { return true; } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { boolean result = false; try { float diffY = e2.getY() - e1.getY(); float diffX = e2.getX() - e1.getX(); if (Math.abs(diffX) &gt; Math.abs(diffY)) { if (Math.abs(diffX) &gt; SWIPE_THRESHOLD &amp;&amp; Math.abs(velocityX) &gt; SWIPE_VELOCITY_THRESHOLD) { if (diffX &gt; 0) { onSwipeRight(); } else { onSwipeLeft(); } } } else { if (Math.abs(diffY) &gt; SWIPE_THRESHOLD &amp;&amp; Math.abs(velocityY) &gt; SWIPE_VELOCITY_THRESHOLD) { if (diffY &gt; 0) { onSwipeBottom(); } else { onSwipeTop(); } } } } catch (Exception exception) { exception.printStackTrace(); } return result; } ...methods... } </code></pre>

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.
