SYSZUXpinyin 只能用到arm上， x86下用不了。原因是SYSZUXpinyin的实现，用到了一个QWSinputMethod
的类，这个类是arm平台的qt库所特有的。还记得我们在终端里启用qt程序后面要加个-qws参数，原因就在这。
所以，用SYSZUXpinyin在arm平台尽管移植成功，但pc机上跑不了，增加了调试的复杂性。希望以后SYSZUXpinyin能考虑下这个问题！
就为了在pc上跑通SYSZUXpinyin，浪费了我一个上午时间查资料
先说说我的测试机器：nexus s，操作系统：android 4.1。以下的结果都是通过nexus s上测试通过。
还是直接上代码

.MyMapABCLocationListener和MyMapABCLocationManager是参考别人代码封转的，由于篇幅的关系不给出来了（类详见代码：TestMapABCDemo.zip 很不错的参考代码）
我想说是旋转图片的问题。经过实践，如果一个图片经过旋转后，它的中心位置会发生改变。之前我的做法是获取原图的的中心位置，但是发现后面画出来的图片会“漂”
还有的是onResume和onDestory。注销了listener之后一定要把它注册回去，不然就不会监听消息了。
