copied!<p>The touch handling events are present in the <code>javax.microedition.lcdui.Canvas package.</code> They are:</p> <ul> <li><p><strong>hasPointerEvents()</strong></p> <p>Returns: boolean</p> <p>Description: Returns true if device supports touch-screen input.</p></li> <li><p><strong>hasPointerMotionEvents()</strong></p> <p>Returns: boolean</p> <p>Description: Returns true if device supports detection of press, release and drag events.</p></li> <li><p><strong>pointerPressed(int x, int y)</strong></p> <p>Returns: void</p> <p>Description: Invoked when a press event is triggered. The x and y variables will contain the coordinates of the location which was pressed.</p></li> <li><p><strong>pointerReleased(int x, int y)</strong></p> <p>Returns: void</p> <p>Description: Similar to <code>pointerPressed()</code> except that it is invoked when the stylus/finger is released from the screen.</p></li> <li><p><strong>PointerDragged()</strong></p> <p>Returns: void</p> <p>Description: Invoked in response to a drag event</p></li> </ul> <p>(Strictly, these are not touch-screen events specifically. They could relate to any kind of pointer-based input, like a mouse or trackball. However, I have only seen them supported on touch-screen devices.)</p> <p>You need no specific JSRs. These features are standard in MIDP-1.0 and later. Since they exist on all MIDP devices, you do not need a specific "touch" version of your application.</p> <p>Look at some examples,</p> <p><a href="http://www.jappit.com/blog/2008/10/06/touch-and-j2me-part-1-how-scroll-an-image/" rel="nofollow">How scroll an image?</a></p> <p><a href="http://www.substanceofcode.com/2009/07/29/coding-touchscreen-scrolling-in-java-me/" rel="nofollow">Coding Touchscreen Scrolling in Java ME</a></p>
