copied!<p>I had run into this problem at a hackathon. There's no way you can solve it with GestureOverlayView, so you have to use motion events. GestureOverlayView however works with slightly more "detailed" gestures, like a circle. What I've noticed is that GestureOverlayView best works for closed figures. So, motionEvent sensor it is. I found the code <a href="https://stackoverflow.com/questions/937313/android-basic-gesture-detection/938657#938657">here</a>. I modified Gav's answer for vertical swipes too. Haven't tested it though, but positive that it should work.</p> <p>Here's an example:</p> <pre><code>public class SelectFilterActivity extends Activity implements OnClickListener { private static final int SWIPE_MIN_DISTANCE = 120; private static final int SWIPE_MAX_OFF_PATH = 250; private static final int SWIPE_THRESHOLD_VELOCITY = 200; private GestureDetector gestureDetector; View.OnTouchListener gestureListener; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); /* ... */ // Gesture detection gestureDetector = new GestureDetector(new MyGestureDetector()); gestureListener = new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { return gestureDetector.onTouchEvent(event); } }; } class MyGestureDetector extends SimpleOnGestureListener { @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { // downward swipe if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) Toast.makeText(SelectFilterActivity.this, "Downward Swipe", Toast.LENGTH_SHORT).show(); else if (Math.abs(e2.getY() - e1.getY()) > SWIPE_MAX_OFF_PATH && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) Toast.makeText(SelectFilterActivity.this, "Upward Swipe", Toast.LENGTH_SHORT).show(); // right to left swipe else if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { Toast.makeText(SelectFilterActivity.this, "Left Swipe", Toast.LENGTH_SHORT).show(); } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { Toast.makeText(SelectFilterActivity.this, "Right Swipe", Toast.LENGTH_SHORT).show(); } } catch (Exception e) { // nothing } return false; } } </code></pre> <p>Now add it to the views where you'd like gesture detection,</p> <pre><code>// Do this for each view added to the grid imageView.setOnClickListener(SelectFilterActivity.this); imageView.setOnTouchListener(gestureListener); </code></pre> <p>Cheers to <a href="https://stackoverflow.com/users/111734/gav">Gav</a> for the code!</p>
