AndroidGPS定位简单DEMO
使用GPS定位，首先，需要在清单文件（AndroidManifest.xml）中注册获取定位的权限：**1.获取位置管理器对象LocationManager**```importandroid.location.LocationManager;LocationManagerlm;//lm=(LocationManager)this.getSystemService(Context`.LOCATION_SERVICE);//```**2.一般使用LocationManager的getLastKnownLocation(LocationManager.GPS_PROVIDER);方法获取Location对象**```Stringprovider=LocationManager.GPS_PROVIDER;//指定LocationManager的定位方法Locationlocation=locationManager.getLastKnownLocation(provider);//调用getLastKnownLocation()方法获取当前的位置信息```不过不建议用这种方法，有几点原因：一，在很多提供定位服务的应用程序中，不仅需要获取当前的位置信息，还需要监视位置的变化，在位置改变时调用特定的处理方法，其中LocationManager提供了一种便捷、高效的位置监视方法requestLocationUpdates()，可以根据位置的距离变化和时间间隔设定，产生位置改变事件的条件，这样可以避免因微小的距离变化而产生大量的位置改变事件。
二，当你开启GPS，provider的值为GPS。
这时的定位方式为GPS，由于GPS定位慢，所以它不可能立即返回你一个Location对象，所以就返回null了。
**3.推荐locationManager.requestLocationUpdates();方法**LocationManager中设定监听位置变化的代码如下：```lm.requestLocationUpdates(LocationManager.GPS_PROVIDER,2000,10,newMyLocationListener());``` 本软件ID:9408324
