首页 / 移动开发 / Android / Android实现Service获取当前位置(GPS+基站)的方法

本文实例讲述了Android实现Service获取当前位置(GPS+基站)的方法。分享给大家供大家参考。具体如下:
需求详情:
1)、Service中每隔1秒执行一次定位操作(GPS+基站)
2)、定位的结果实时显示在界面上(要求得到经度、纬度)
技术支持:
1)、获取经纬度
通过GPS+基站获取经纬度,先通过GPS来获取,如果为空改用基站进行获取–>GPS+基站(基站获取支持联通、电信、移动)。
2)、实时获取经纬度
为了达到实时获取经纬度,需在后台启动获取经纬度的Service,然后把经纬度数据通过广播发送出去,在需要的地方进行广播注册(比如在Activity中注册广播,显示在界面中)–>涉及到Service+BroadcastReceiver+Activity+Thread等知识点。
备注:本文注重实践,如有看不懂的,先去巩固下知识点,可以去看看前面相关的几篇文章。
1、CellInfo实体类–>基站信息
package com.ljq.activity;/** * 基站信息 ** @author jiqinlin **/public class CellInfo { /** 基站id,用来找到基站的位置 */ private int cellId; /** 移动国家码,共3位,中国为460,即imsi前3位 */ private String mobileCountryCode="460"; /** 移动网络码,共2位,在中国,移动的代码为00和02,联通的代码为01,电信的代码为03,即imsi第4~5位 */ private String mobileNetworkCode="0"; /** 地区区域码 */ private int locationAreaCode; /** 信号类型[选 gsm|cdma|wcdma] */ private String radioType=""; public CellInfo() { } public int getCellId() { return cellId; } public void setCellId(int cellId) { this.cellId = cellId; } public String getMobileCountryCode() { return mobileCountryCode; } public void setMobileCountryCode(String mobileCountryCode) { this.mobileCountryCode = mobileCountryCode; } public String getMobileNetworkCode() { return mobileNetworkCode; } public void setMobileNetworkCode(String mobileNetworkCode) { this.mobileNetworkCode = mobileNetworkCode; } public int getLocationAreaCode() { return locationAreaCode; } public void setLocationAreaCode(int locationAreaCode) { this.locationAreaCode = locationAreaCode; } public String getRadioType() { return radioType; } public void setRadioType(String radioType) { this.radioType = radioType; }}
2、Gps类–>Gps封装类,用来获取经纬度
package com.ljq.activity;import android.content.Context;import android.location.Criteria;import android.location.Location;import android.location.LocationListener;import android.location.LocationManager;import android.os.Bundle;public class Gps{ private Location location = null; private LocationManager locationManager = null; private Context context = null; /** * 初始化** @param ctx */ public Gps(Context ctx) { context=ctx; locationManager=(LocationManager)context.getSystemService(Context.LOCATION_SERVICE); location = locationManager.getLastKnownLocation(getProvider()); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2000, 10, locationListener); } // 获取Location Provider private String getProvider() { // 构建位置查询条件 Criteria criteria = new Criteria(); // 查询精度:高 criteria.setAccuracy(Criteria.ACCURACY_FINE); // 是否查询海拨:否 criteria.setAltitudeRequired(false); // 是否查询方位角 : 否 criteria.setBearingRequired(false); // 是否允许付费:是 criteria.setCostAllowed(true); // 电量要求:低 criteria.setPowerRequirement(Criteria.POWER_LOW); // 返回最合适的符合条件的provider,第2个参数为true说明 , 如果只有一个provider是有效的,则返回当前provider return locationManager.getBestProvider(criteria, true); } private LocationListener locationListener = new LocationListener() { // 位置发生改变后调用 public void onLocationChanged(Location l) {if(l!=null){location=l;} } // provider 被用户关闭后调用 public void onProviderDisabled(String provider) {location=null; } // provider 被用户开启后调用 public void onProviderEnabled(String provider) {Location l = locationManager.getLastKnownLocation(provider);if(l!=null){location=l;} } // provider 状态变化时调用 public void onStatusChanged(String provider, int status, Bundle extras) { } }; public Location getLocation(){ return location; } public void closeLocation(){ if(locationManager!=null){if(locationListener!=null){locationManager.removeUpdates(locationListener);locationListener=null;}locationManager=null; } }}
3、GpsService服务类
package com.ljq.activity;import java.util.ArrayList;import android.app.Service;import android.content.Intent;import android.location.Location;import android.os.IBinder;import android.util.Log;public class GpsService extends Service { ArrayList<CellInfo> cellIds = null; private Gps gps=null; private boolean threadDisable=false;private final static String TAG=GpsService.class.getSimpleName(); @Override public void onCreate() { super.onCreate(); gps=new Gps(GpsService.this); cellIds=UtilTool.init(GpsService.this); new Thread(new Runnable(){@Overridepublic void run() {while (!threadDisable) {try { Thread.sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } if(gps!=null){ //当结束服务时gps为空 //获取经纬度 Location location=gps.getLocation(); //如果gps无法获取经纬度,改用基站定位获取 if(location==null){Log.v(TAG, "gps location null"); //2.根据基站信息获取经纬度try {location = UtilTool.callGear(GpsService.this, cellIds);} catch (Exception e) {location=null;e.printStackTrace();}if(location==null){Log.v(TAG, "cell location null"); } } //发送广播 Intent intent=new Intent(); intent.putExtra("lat", location==null?"":location.getLatitude()+"");intent.putExtra("lon", location==null?"":location.getLongitude()+"");intent.setAction("com.ljq.activity.GpsService");sendBroadcast(intent); }}} }).start(); } @Override public void onDestroy() { threadDisable=true; if(cellIds!=null&&cellIds.size()>0){cellIds=null; } if(gps!=null){gps.closeLocation();gps=null; } super.onDestroy(); } @Override public IBinder onBind(Intent arg0) { return null; }}
4、GpsActivity–>在界面上实时显示经纬度数据
package com.ljq.activity;import android.app.Activity;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.IntentFilter;import android.location.Location;import android.location.LocationManager;import android.os.Bundle;import android.util.Log;import android.widget.EditText;import android.widget.Toast;public class GpsActivity extends Activity { private Double homeLat=26.0673834d; //宿舍纬度 private Double homeLon=119.3119936d; //宿舍经度 private EditText editText = null; private MyReceiver receiver=null;private final static String TAG=GpsActivity.class.getSimpleName(); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); editText=(EditText)findViewById(R.id.editText); //判断GPS是否可用 Log.i(TAG, UtilTool.isGpsEnabled((LocationManager)getSystemService(Context.LOCATION_SERVICE))+""); if(!UtilTool.isGpsEnabled((LocationManager)getSystemService(Context.LOCATION_SERVICE))){Toast.makeText(this, "GSP当前已禁用,请在您的系统设置屏幕启动。", Toast.LENGTH_LONG).show();Intent callGPSSettingIntent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivity(callGPSSettingIntent);return; } //启动服务 startService(new Intent(this, GpsService.class)); //注册广播 receiver=new MyReceiver(); IntentFilter filter=new IntentFilter(); filter.addAction("com.ljq.activity.GpsService"); registerReceiver(receiver, filter); } //获取广播数据 private class MyReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) {Bundle bundle=intent.getExtras(); String lon=bundle.getString("lon");String lat=bundle.getString("lat"); if(lon!=null&&!"".equals(lon)&&lat!=null&&!"".equals(lat)){double distance=getDistance(Double.parseDouble(lat),Double.parseDouble(lon), homeLat, homeLon);editText.setText("目前经纬度
经度:"+lon+"
纬度:"+lat+"
离宿舍距离:"+java.lang.Math.abs(distance));}else{editText.setText("目前经纬度
经度:"+lon+"
纬度:"+lat);} } } @Override protected void onDestroy() { //注销服务 unregisterReceiver(receiver); //结束服务,如果想让服务一直运行就注销此句 stopService(new Intent(this, GpsService.class)); super.onDestroy(); } /** * 把经纬度换算成距离 ** @param lat1 开始纬度 * @param lon1 开始经度 * @param lat2 结束纬度 * @param lon2 结束经度 * @return */ private double getDistance(double lat1, double lon1, double lat2, double lon2) { float[] results = new float[1]; Location.distanceBetween(lat1, lon1, lat2, lon2, results); return results[0]; } }
5、UtilTool–>工具类

6、main.xml–>布局文件
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"><EditText android:layout_width="fill_parent"android:layout_height="wrap_content"android:cursorVisible="false"android:editable="false"android:id="@+id/editText"/></LinearLayout>
7、清单文件
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.ljq.activity" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".GpsActivity"android:label="@string/app_name"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter> </activity> <service android:label="GPS服务" android:name=".GpsService" /> </application> <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /></manifest>
效果如下:
