Android 基站定位源代码

TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); 

通过这个方式就可以得到TelephonyManager接口。
这个接口的源代码可以通过设置在项目里面查看，这里不具体附上了。
得到TelephonyManager后，由于针对不同的运营商，代码有所不同，所以需要判断getNetworkType()
在源代码里面有如下的类型定义

/** Network type is unknown */      public static final int NETWORK_TYPE_UNKNOWN = 0;      /** Current network is GPRS */      public static final int NETWORK_TYPE_GPRS = 1;      /** Current network is EDGE */      public static final int NETWORK_TYPE_EDGE = 2;      /** Current network is UMTS */      public static final int NETWORK_TYPE_UMTS = 3;      /** Current network is CDMA: Either IS95A or IS95B*/      public static final int NETWORK_TYPE_CDMA = 4;      /** Current network is EVDO revision 0*/      public static final int NETWORK_TYPE_EVDO_0 = 5;      /** Current network is EVDO revision A*/      public static final int NETWORK_TYPE_EVDO_A = 6;      /** Current network is 1xRTT*/      public static final int NETWORK_TYPE_1xRTT = 7;      /** Current network is HSDPA */      public static final int NETWORK_TYPE_HSDPA = 8;      /** Current network is HSUPA */      public static final int NETWORK_TYPE_HSUPA = 9;      /** Current network is HSPA */      public static final int NETWORK_TYPE_HSPA = 10;

2 联通、移动、电信不同制式在获取基站位置的代码区别。

这部分是我实际测试出来的，经过无数次的拆机，放卡，才实现了不同制式的完美实现。
代码如下：

TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);  int type = tm.getNetworkType();  //中国电信为CTC  //NETWORK_TYPE_EVDO_A是中国电信3G的getNetworkType  //NETWORK_TYPE_CDMA电信2G是CDMA  if (type == TelephonyManager.NETWORK_TYPE_EVDO_A || type == TelephonyManager.NETWORK_TYPE_CDMA || type ==TelephonyManager.NETWORK_TYPE_1xRTT)  {  }  //移动2G卡 + CMCC + 2  //type = NETWORK_TYPE_EDGE  else if(type == TelephonyManager.NETWORK_TYPE_EDGE)  {  }  //联通的2G经过测试 China Unicom   1 NETWORK_TYPE_GPRS  else if(type == TelephonyManager.NETWORK_TYPE_GPRS)  {     }  else  {  tv.setText("Current Not Support This Type.");  }

3 通过基站的基本信息，通过Google Gears获取对应的GPS经纬度。
这部分前面的两篇文章都有提到，代码参考了网友们的代码，感谢感谢。
