/**
* The <code>DeviceScreen</code> class is a base class for any screen that needs complete
* control over how it is painted. It is based on and similar to the MIDP
* <code>Canvas</code> class.
* <p>
* This class removes the following methods from the MIDP <code>Canvas</code> class:
* <ul>
* <li><code>isDoubleBuffered</code> - This class is always double buffered.
* <li><code>hasPointerEvents</code> and <code>hasPointerMotionEvents</code> - There is
* no use for this method. Implement the pointer event methods and
* if the device has no pointer they will be ignored.
* <li> - Same reason as <code>hasPointerEvents</code>.
* <li><code>hasRepeatEvents</code> - This class always has key repeat events.
* <li><code>getKeyName</code> - The application should define the names to make them
* consistent across all devices.
* <li><code>getKeyCode</code> - The key code is passed into the key event methods.
* <li><code>getGameAction</code> - The game action is passed into the key event methods.
* <li><code>sizeChanged</code> - This method is notoriously buggy and applications
* should use <code>getWidth</code> and <code>getHeight</code> instead.
* <li><code>getTicker</code> and <code>setTicker</code> - The ticker functionality has
* not been implemented.
* <li><code>addCommand</code>, <code>removeCommand</code>, and <code>setCommandListener</code> -
* Menu options have been replaced with something that works across all
* MIDP 2.0 devices. There are left and right menu options. See
* <code>setMenuText</code> for details.
* </ul>

wangtaikun2013-05-08还不错，不过不太明白。有服务端更好
Maxize2012-06-21为了要弄清楚一个东西。然后下载了。事实上也能帮我解决。
ionlywantto2013-06-08代码有点简单
alain732012-11-20谢谢分享，要有服务端的代码就更好
