最近在看android关于定位的方式，查了很多资料，也做了相关实验，在手机上做了测试，下面总结：
一共有三种定位方式，一种是GPS，一种是通过网络的方式，一种则是在基于基站的方式，但是，不管哪种方式，都需要开启网络或者GPS
首先添加权限
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
在COARSE_LOCATION是用于基站定位的时候用的，没有这个权限，在获取getCellLocation的时候报错。
第一种方式通过JASON来实现，是通过基站方式的，引用文章地址：/dartagnan/archive//3/9.html，下载只是实现定位的代码
/** * Google定位的实现.<br/> * Geolocation的详细信息请参见：<br/> * <a * href="/apis/gears/geolocation_network_protocol.html" mce_href="/apis/gears/geolocation_network_protocol.html"> */apis/gears/geolocation_network_protocol.html</a> */ public class LocationAct extends Activity { private TextView txtInfo; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button btn = (Button) findViewById(R.id.btnStart); txtInfo = (TextView) findViewById(R.id.txtInfo); btn.setOnClickListener(new Button.OnClickListener() { public void onClick(View view) { getLocation(); } }); } private void getLocation() { TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); GsmCellLocation gsmCell = (GsmCellLocation) tm.getCellLocation(); int cid = gsmCell.getCid(); int lac = gsmCell.getLac(); String netOperator = tm.getNetworkOperator(); int mcc = Integer.valueOf(netOperator.substring(0, 3)); int mnc = Integer.valueOf(netOperator.substring(3, 5)); JSONObject holder = new JSONObject(); JSONArray array = new JSONArray(); JSONObject data = new JSONObject(); try { holder.put("version", "1.1.0"); holder.put("host", ""); holder.put("address_language", "zh_CN"); holder.put("request_address", true); holder.put("radio_type", "gsm"); holder.put("carrier", "HTC"); data.put("cell_id", cid); data.put("location_area_code", lac); data.put("mobile_countyr_code", mcc); data.put("mobile_network_code", mnc); array.put(data); holder.put("cell_towers", array); } catch (JSONException e) { e.printStackTrace(); } DefaultHttpClient client = new DefaultHttpClient(); HttpPost httpPost = new HttpPost("/loc/json"); StringEntity stringEntity = null; try { stringEntity = new StringEntity(holder.toString()); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } httpPost.setEntity(stringEntity); HttpResponse httpResponse = null; try { httpResponse = client.execute(httpPost); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } HttpEntity httpEntity = httpResponse.getEntity(); InputStream is = null; try { is = httpEntity.getContent(); } catch (IllegalStateException e) { e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch blocke.printStackTrace(); } InputStreamReader isr = new InputStreamReader(is); BufferedReader reader = new BufferedReader(isr); StringBuffer stringBuffer = new StringBuffer(); try { String result = ""; while ((result = reader.readLine()) != null) { stringBuffer.append(result); } } catch (IOException e) { e.printStackTrace(); } txtInfo.setText(stringBuffer.toString()); } }
第二种通过严格的GPS来定位，引用文章地址：/wisekingokok/archive//09/06/2168479.html，这里只引用代码
public class MainActivity extends Activity {private LocationManager locationManager;private GpsStatus gpsstatus;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);//获取到LocationManager对象 locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);//根据设置的Criteria对象，获取最符合此标准的provider对象 String currentProvider = locationManager.getProvider(LocationManager.GPS_PROVIDER).getName();//根据当前provider对象获取最后一次位置信息 Location currentLocation = locationManager.getLastKnownLocation(currentProvider);//如果位置信息为null，则请求更新位置信息 if(currentLocation == null){locationManager.requestLocationUpdates(currentProvider, 0, 0, locationListener);}//增加GPS状态监听器 locationManager.addGpsStatusListener(gpsListener);//直到获得最后一次位置信息为止，如果未获得最后一次位置信息，则显示默认经纬度//每隔10秒获取一次位置信息 while(true){currentLocation = locationManager.getLastKnownLocation(currentProvider);if(currentLocation != null){Log.d("Location", "Latitude: " + currentLocation.getLatitude());Log.d("Location", "location: " + currentLocation.getLongitude());break;}else{Log.d("Location", "Latitude: " + 0);Log.d("Location", "location: " + 0);}try {Thread.sleep(10000);} catch (InterruptedException e) {Log.e("Location", e.getMessage());}}}private GpsStatus.Listener gpsListener = new GpsStatus.Listener(){//GPS状态发生变化时触发 @Overridepublic void onGpsStatusChanged(int event) {//获取当前状态 gpsstatus=locationManager.getGpsStatus(null);switch(event){//第一次定位时的事件 case GpsStatus.GPS_EVENT_FIRST_FIX:break;//开始定位的事件 case GpsStatus.GPS_EVENT_STARTED:break;//发送GPS卫星状态事件 case GpsStatus.GPS_EVENT_SATELLITE_STATUS:Toast.makeText(MainActivity.this, "GPS_EVENT_SATELLITE_STATUS", Toast.LENGTH_SHORT).show();Iterable<GpsSatellite> allSatellites = gpsstatus.getSatellites(); Iterator<GpsSatellite> it=allSatellites.iterator(); int count = 0;while(it.hasNext()) { count++;}Toast.makeText(MainActivity.this, "Satellite Count:" + count, Toast.LENGTH_SHORT).show();break;//停止定位事件 case GpsStatus.GPS_EVENT_STOPPED:Log.d("Location", "GPS_EVENT_STOPPED");break;}}};//创建位置监听器private LocationListener locationListener = new LocationListener(){//位置发生改变时调用 @Overridepublic void onLocationChanged(Location location) {Log.d("Location", "onLocationChanged");}//provider失效时调用 @Overridepublic void onProviderDisabled(String provider) {Log.d("Location", "onProviderDisabled");}//provider启用时调用 @Overridepublic void onProviderEnabled(String provider) {Log.d("Location", "onProviderEnabled");}//状态改变时调用 @Overridepublic void onStatusChanged(String provider, int status, Bundle extras) {Log.d("Location", "onStatusChanged");}};}
第三种主要是通过网络的方式来定位，引用文章地址：/wisekingokok/archive//09/05/2167755.html，这里只写代码
package com.test;import java.io.IOException;import java.util.List;import android.app.Activity;import android.location.Address;import android.location.Criteria;import android.location.Geocoder;import android.location.Location;import android.location.LocationListener;import android.location.LocationManager;import android.os.Bundle;import android.util.Log;import android.widget.Toast;public class MainActivity extends Activity {@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);//获取到LocationManager对象 LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);//创建一个Criteria对象 Criteria criteria = new Criteria();//设置粗略精确度 criteria.setAccuracy(Criteria.ACCURACY_COARSE);//设置是否需要返回海拔信息 criteria.setAltitudeRequired(false);//设置是否需要返回方位信息 criteria.setBearingRequired(false);//设置是否允许付费服务 criteria.setCostAllowed(true);//设置电量消耗等级 criteria.setPowerRequirement(Criteria.POWER_HIGH);//设置是否需要返回速度信息 criteria.setSpeedRequired(false);//根据设置的Criteria对象，获取最符合此标准的provider对象 String currentProvider = locationManager.getBestProvider(criteria, true);Log.d("Location", "currentProvider: " + currentProvider);//根据当前provider对象获取最后一次位置信息 Location currentLocation = locationManager.getLastKnownLocation(currentProvider);//如果位置信息为null，则请求更新位置信息 if(currentLocation == null){locationManager.requestLocationUpdates(currentProvider, 0, 0, locationListener);}//直到获得最后一次位置信息为止，如果未获得最后一次位置信息，则显示默认经纬度//每隔10秒获取一次位置信息 while(true){currentLocation = locationManager.getLastKnownLocation(currentProvider);if(currentLocation != null){Log.d("Location", "Latitude: " + currentLocation.getLatitude());Log.d("Location", "location: " + currentLocation.getLongitude());break;}else{Log.d("Location", "Latitude: " + 0);Log.d("Location", "location: " + 0);}try {Thread.sleep(10000);} catch (InterruptedException e) {Log.e("Location", e.getMessage());}}//解析地址并显示 Geocoder geoCoder = new Geocoder(this);try {int latitude = (int) currentLocation.getLatitude();int longitude = (int) currentLocation.getLongitude();List<Address> list = geoCoder.getFromLocation(latitude, longitude, 2);for(int i=0; i<list.size(); i++){Address address = list.get(i); Toast.makeText(MainActivity.this, address.getCountryName() + address.getAdminArea() + address.getFeatureName(), Toast.LENGTH_LONG).show();}} catch (IOException e) {Toast.makeText(MainActivity.this,e.getMessage(), Toast.LENGTH_LONG).show();}}//创建位置监听器private LocationListener locationListener = new LocationListener(){//位置发生改变时调用 @Overridepublic void onLocationChanged(Location location) {Log.d("Location", "onLocationChanged");Log.d("Location", "onLocationChanged Latitude" + location.getLatitude());Log.d("Location", "onLocationChanged location" + location.getLongitude());}//provider失效时调用 @Overridepublic void onProviderDisabled(String provider) {Log.d("Location", "onProviderDisabled");}//provider启用时调用 @Overridepublic void onProviderEnabled(String provider) {Log.d("Location", "onProviderEnabled");}//状态改变时调用 @Overridepublic void onStatusChanged(String provider, int status, Bundle extras) {Log.d("Location", "onStatusChanged");}};}
