之前有一片关于基站定位的文章，当时的测试环境是小米+移动，比较顺利。
但在实际运用中就出现问题了-联通和电信的号完全没办法定位！
最好的解决方法就是用第三方sdk来定位了。
百度的定位sdk还是很不错的，可以通过wifi，gps，gprs来定位，和运营商就无关了。
最终效果：
界面就一个button'和textview，点击按钮之后就开始定位，获取结果之后在textview中显示。
实现步骤：
添加sdk 去这里下载最新的sdk，现在是3.3.
将liblocSDK3.so文件拷贝到libs/armeabi目录下。将locSDK3.3.jar文件拷贝到工程的libs目录下，并在工程属性->Java Build Path->Libraries中选择“Add JARs”，选定locSDK3.3.jar，确定后返回。这样您就可以在程序中使用百度定位SDK了。
添加service
在manifest文件中添加：
申明权限
主activity代码
package com.example.locationtest; import android.os.Bundle; import android.os.Vibrator; import com.baidu.location.BDLocation; import com.baidu.location.BDLocationListener; import com.baidu.location.LocationClient; import com.baidu.location.LocationClientOption; import com.baidu.location.BDNotifyListener; import android.app.Activity; import android.app.Service; import android.util.Log; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; public class MainActivity extends Activity { private LocationClient mLocationClient; public BDLocationListener myListener; private Button mButton; private TextView mTv; private Vibrator mVibrator01 =null; private boolean mIsStart; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mButton = (Button)findViewById(R.id.button1); mTv = (TextView)findViewById(R.id.textview1); mIsStart = false; mLocationClient = new LocationClient(this.getApplicationContext()); myListener = new MyLocationListener(); mLocationClient.registerLocationListener(myListener); LocationClientOption locationOption = new LocationClientOption(); locationOption.setOpenGps(true); locationOption.setCoorType("bd09ll"); locationOption.setPriority(WorkFirst); locationOption.setAddrType("all"); locationOption.setProdName("BaiduLocation"); locationOption.setScanSpan(5000);//设置发起定位请求的间隔时间为5000ms locationOption.disableCache(true);//禁止启用缓存定位 locationOption.setPoiNumber(5);//最多返回POI个数 locationOption.setPoiDistance(1000); //poi查询距离 locationOption.setPoiExtraInfo(true); //是否需要POI的电话和地址等详细信息 mLocationClient.setLocOption(locationOption); Log.i("Baidu", "BaiduMapMyLocationActivity 开启定位"); mLocationClient.start(); mButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { // TODO Auto-generated method stub if (!mIsStart) { mLocationClient.start(); mButton.setText("Stop"); mIsStart = true; } else { mLocationClient.stop(); mIsStart = false; mButton.setText("Start"); } } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.activity_main, menu); return true; } public class MyLocationListener implements BDLocationListener { @Override public void onReceiveLocation(BDLocation location) { if (location == null) return ; StringBuffer sb = new StringBuffer(256); sb.append("time : "); sb.append(location.getTime()); sb.append("\nerror code : "); sb.append(location.getLocType()); sb.append("\nlatitude : "); sb.append(location.getLatitude()); sb.append("\nlontitude : "); sb.append(location.getLongitude()); sb.append("\nradius : "); sb.append(location.getRadius()); if (location.getLocType() == BDLocation.TypeGpsLocation){ sb.append("\nspeed : "); sb.append(location.getSpeed()); sb.append("\nsatellite : "); sb.append(location.getSatelliteNumber()); } else if (location.getLocType() == BDLocation.TypeNetWorkLocation){ sb.append("\naddr : "); sb.append(location.getAddrStr()); } mTv.setText(sb); logMsg(sb.toString()); } public void onReceivePoi(BDLocation poiLocation) { if (poiLocation == null){ return ; } StringBuffer sb = new StringBuffer(256); sb.append("Poi time : "); sb.append(poiLocation.getTime()); sb.append("\nerror code : "); sb.append(poiLocation.getLocType()); sb.append("\nlatitude : "); sb.append(poiLocation.getLatitude()); sb.append("\nlontitude : "); sb.append(poiLocation.getLongitude()); sb.append("\nradius : "); sb.append(poiLocation.getRadius()); if (poiLocation.getLocType() == BDLocation.TypeNetWorkLocation){ sb.append("\naddr : "); sb.append(poiLocation.getAddrStr()); } if(poiLocation.hasPoi()){ sb.append("\nPoi:"); sb.append(poiLocation.getPoi()); }else{ sb.append("noPoi information"); } mTv.setText(sb); logMsg(sb.toString()); } } private void logMsg(String s) { System.out.println(s); } @Override public void onDestroy() { mLocationClient.stop(); super.onDestroy(); } }
