Android 系统api实现定位及使用百度提供的api来实现定位_api快速定位controller位置

目前在国内使用定位的方法主要是 

1. Android系统提供的 LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

2. 百度提供的api（需要在应用程序中加入相应的.so,.jar包）百度提供的定位api，与你本机是否有装百度地图程序程序没有关系

下面简单介绍一下使用方法

Android系统提供的API使用：

LocationManager locationManager ;
	
	void getLocationInfo() {
		
		if(locationManager == null){
			locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
		}
		Criteria criteria = new Criteria();
		criteria.setAccuracy(Criteria.ACCURACY_COARSE); // 设置为最大精度
		criteria.setAltitudeRequired(false); // 不要求海拔信息
		criteria.setCostAllowed(true);//是否允许付费
		criteria.setPowerRequirement(Criteria.POWER_LOW); // 对电量的要求
		criteria.setBearingRequired(false); // 不要求Bearing信息
		
		String bestProvider = locationManager.getBestProvider(criteria, true);
		IWLog.i(TAG, "bestProvider=" + bestProvider);
		
		Location location = locationManager.getLastKnownLocation(bestProvider);
		updateWithNewLocation(location);
	    
		locationManager.requestLocationUpdates(bestProvider, 1000, 2, mLocationListener);//1秒，2米
		
		
	}
 
	
	LocationListener mLocationListener = new LocationListener() {
		
		@Override
		public void onLocationChanged(Location location) {
			
			if(locationManager != null){
				locationManager.removeUpdates(mLocationListener);//我这里，只需要定位一次就可以了
			}
			updateWithNewLocation(location);
			
		}
 
		@Override
		public void onStatusChanged(String provider, int status, Bundle extras) {
			IWLog.i(TAG, "onStatusChanged");
			
		}
 
		@Override
		public void onProviderEnabled(String provider) {
			IWLog.i(TAG, "onProviderEnabled");
			
		}
 
		@Override
		public void onProviderDisabled(String provider) {
			IWLog.i(TAG, "onProviderDisabled");
			
		}
	};
	
	private void updateWithNewLocation(Location location){
		if (location != null) {
			double latitude = location.getLatitude(); // 经度
			double longitude = location.getLongitude(); // 纬度
			//double altitude = location.getAltitude(); // 海拔
			
			///mMainFragment.navLoadUrl(String.format(NavigationUrl.NEARBY_URL,longitude,latitude));
			
			IWLog.v(TAG, "latitude " + latitude + "  longitude:" + longitude);
			///UtilWidget.showToast(this, "Latitude :" + location.getLatitude()+""+"Longitude :" +  location.getLatitude());
		}else{
			IWLog.v(TAG, "don't know location info");
			UtilWidget.showToast(this, "无法获取位置信息");
		}
	}

百度定位API

百度官方说明：http://api.map.baidu.com/lbsapi/cloud/geosdk-android.htm

下载包及demo：http://api.map.baidu.com/lbsapi/cloud/geosdk-android-download.htm

可以直接参考百度提供的demo来实现自己的定位

MainActivity中的代码：

	/**
	 * 监听函数，又新位置的时候，格式化成字符串，输出到屏幕中
	 */
	public class MyLocationListenner 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("\n省：");
//				sb.append(location.getProvince());
//				sb.append("\n市：");
//				sb.append(location.getCity());
//				sb.append("\n区/县：");
//				sb.append(location.getDistrict());
				sb.append("\naddr : ");
				sb.append(location.getAddrStr());
			}
			sb.append("\nsdk version : ");
			sb.append(mLocationClient.getVersion());
			sb.append("\nisCellChangeFlag : ");
			sb.append(location.isCellChangeFlag());
			//logMsg(sb.toString());
			Log.i(TAG, sb.toString());
			
			UtilWidget.cancelProgressDialog();
			updateWithNewLocation(location);
		}
		
		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");
			}
			//logMsg(sb.toString());
		}
	}
	
	//设置相关参数
	public void setLocationOption() {
		LocationClientOption option = new LocationClientOption();
		option.setOpenGps(true);// 打开gprs
		// option.setAddrType("all");// 返回的定位结果包含地址信息
		option.setCoorType("bd09ll");// 返回的定位结果是百度经纬度,默认值gcj02
		option.setScanSpan(5);// 设置发起定位请求的间隔时间为5000ms
								// //设置定位模式，小于1秒则一次定位;大于等于1秒则定时定位
		option.disableCache(true);// 禁止启用缓存定位
		// option.setPoiNumber(5); // 最多返回POI个数
		// option.setPoiDistance(1000); // poi查询距离
		// /option.setPoiExtraInfo(true); // 是否需要POI的电话和地址等详细信息
 
		// option.setPriority(LocationClientOption.NetWorkFirst); //设置网络优先
		// option.setPriority(LocationClientOption.GpsFirst); //不设置，默认是gps优先
		mLocationClient.setLocOption(option);
 
	}
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		setContentView(R.layout.activity_main_layout);
		
		//百度定位服务
		mLocationClient = new LocationClient(this);
		//myListener = new MyLocationListenner();
		setLocationOption();
		mLocationClient.registerLocationListener( new MyLocationListenner());
	}
	@Override
	protected void onDestroy() {
		super.onDestroy();
		mLocationClient.stop();
		
	}
在需要开户定位的地方执行 mLocationClient.start();

详细参数请到官试api上参考

最后想说的一句是，在国内可能使用百度定位更好一些。因为我用系统的api很难达到想要的结果
