Android gps定位

我去，好久对没来os来了编辑器都有三种风格了，这愉快的周末即将开始，下午了，来个gps是如何定位的，Android版本的，ios的请绕走。

首先还是需要引入你的权限，在AndroidManifest.xml里加上这几个<!--网络精确定位gps，权限不懂的Google或者看API--><uses-permissionandroid:name="android.permission.INTERNET"/><uses-permissionandroid:name="android.permission.ACCESS_COARSE_LOCATION"/><uses-permissionandroid:name="android.permission.ACCESS_FINE_LOCATION"/>

权限都加上了，看看我的activity

package*********import***********publicclassLocationActivityextendsActivity{privateStringTAG="LocationActivity";privateLocationManagerlocationManager;@OverridepublicvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.main);locationManager=(LocationManager)getSystemService(LOCATION_SERVICE);}@OverrideprotectedvoidonResume(){super.onResume();initData();//init}privatevoidinitData(){if(!locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){Log.i(TAG,"gpsclose");Intentintent=newIntent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);startActivityForResult(intent,0);return;}else{Log.i(TAG,"gpsopen");}StringbestProvider=locationManager.getBestProvider(getCriteria(),true);Locationlocation=locationManager.getLastKnownLocation(bestProvider);updateView(location);/*1000毫秒0米偏移量，更新,定位方式我用的NETWORK_PROVIDER,也可以用GPS_PROVIDER,只是gps在室内好像定不了*/locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,1000,0,locationListener);}privatevoidupdateGps(Locationlocation){if(location!=null){Log.i(TAG,"设备位置信息,经度："+String.valueOf(location.getLongitude())+"纬度："+String.valueOf(location.getLatitude())+"海拔："+String.valueOf(location.getAltitude())）；}else{Log.i(TAG,"暂时未获取到位置");}}privateCriteriagetCriteria(){Criteriacriteria=newCriteria();/*设置定位精确度Criteria.ACCURACY_COARSE比较粗略，Criteria.ACCURACY_FINE则比较精细,此处注意，如果想粗略的定位要去AndroidManifest.xml中加上粗略的权限，*/criteria.setAccuracy(Criteria.ACCURACY_FINE);//设置是否要求速度criteria.setSpeedRequired(false);//设置是否允许运营商收费criteria.setCostAllowed(false);//设置是否需要方位信息criteria.setBearingRequired(false);//设置是否需要海拔信息criteria.setAltitudeRequired(true);//设置对电源的需求criteria.setPowerRequirement(Criteria.POWER_LOW);returncriteria;}privateLocationListenerlocationListener=newLocationListener(){/***位置信息变化时触发*/publicvoidonLocationChanged(Locationlocation){updateGps(location);}/***GPS状态变化时触发*/publicvoidonStatusChanged(Stringprovider,intstatus,Bundleextras){switch(status){//GPS状态为可见时caseLocationProvider.AVAILABLE:Log.i(TAG,"当前GPS状态为可见状态");break;//GPS状态为服务区外时caseLocationProvider.OUT_OF_SERVICE:Log.i(TAG,"当前GPS状态为服务区外状态");break;//GPS状态为暂停服务时caseLocationProvider.TEMPORARILY_UNAVAILABLE:Log.i(TAG,"当前GPS状态为暂停服务状态");break;}}/***GPS开启时触发*/publicvoidonProviderEnabled(Stringprovider){Locationlocation=locationManager.getLastKnownLocation(provider);updateGps(location);}/***GPS禁用时触发*/publicvoidonProviderDisabled(Stringprovider){updateGps(null);}};privateGpsStatus.Listenerlistener=newGpsStatus.Listener(){@OverridepublicvoidonGpsStatusChanged(intevent){switch(event){caseGpsStatus.GPS_EVENT_FIRST_FIX:Log.i(TAG,"第一次定位");break;caseGpsStatus.GPS_EVENT_SATELLITE_STATUS:Log.i(TAG,"卫星状态改变");GpsStatusgpsStatus=locationManager.getGpsStatus(null);intmaxSatellites=gpsStatus.getMaxSatellites();Iterator<GpsSatellite>iters=gpsStatus.getSatellites().iterator();intcount=0;while(iters.hasNext()&&count<=maxSatellites){GpsSatellites=iters.next();count++;}break;caseGpsStatus.GPS_EVENT_STARTED:Log.i(TAG,"定位启动");break;caseGpsStatus.GPS_EVENT_STOPPED:Log.i(TAG,"定位结束");break;}}};}

复制到你类中，有需要import的全部导入即可，运行下查看是否可以获取gps，亲测三星是可以的，比较仓促，不足之处留言。
