工作需要这里对Android自带定位做个小小的记录，GPS测试过可用，网络的，需要再次测试，但是方式都差不多，简单总结如下。
1、首先需要添加权限
<!-- 这个权限用于访问GPS定位--> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> <!-- 用于访问wifi网络信息，wifi信息会用于进行网络定位--> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <!-- 这个权限用于进行网络定位--> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission> <!--网络权限--> <uses-permission android:name="android.permission.INTERNET" />
2、然后推荐在服务里做定位处理MyService可以继承Location网上很多，这里不再继承 LocationListener 了，继承的方法有很多上面有链接。
主要代码实现如下
要使用的参数
private LocationManager mLocationManager; private Location mLocation; private double lat = 0; private double lng = 0; private double alt = 0; // The minimum distance to change Updates in meters private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 刷新距离10m // The minimum time between updates in milliseconds private static final long MIN_TIME_BW_UPDATES = 1000 * 5; // 5 秒
onCreate方法里
@Override public void onCreate() { super.onCreate(); PDALogger.d("onCreate"); ctx = PdaApplication.getInstance(); getLocation();//读取手机端GPS mHandler.postDelayed(uploadGPSRunnable, 3000); }
下面是这个方法getLocation()，划线部分可要可不要
public Location getLocation() { mLocationManager = (LocationManager) ctx.getSystemService(LOCATION_SERVICE); // getting GPS status boolean isGPSEnabled = mLocationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); // getting network status boolean isNetworkEnabled = mLocationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER); if (!isGPSEnabled && !isNetworkEnabled) { // no network provider is enabled } else { if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { } //get the location by gps if (isGPSEnabled) { if (mLocation == null) { mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, mGPSLocationListener); PDALogger.d("GPS Enabled"); if(mLocationManager!=null){ mLocation = mLocationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); } } } else if (isNetworkEnabled) {// First get location from Network Provider if(mLocation==null){ mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, mNetWorkLocationListener); PDALogger.d("Network"); if(mLocationManager!=null){ mLocation = mLocationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); } } } } return mLocation; }
这里是两个监听器GPS和网络的
/** * GPS定位监听器 */ public final LocationListener mGPSLocationListener = new LocationListener() { @Override public void onLocationChanged(Location location) { updateToNewLocation(location); } @Override public void onProviderDisabled(String provider) { updateToNewLocation(null); } @Override public void onProviderEnabled(String provider) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } }; /** * 网络定位监听器 */ public final LocationListener mNetWorkLocationListener = new LocationListener() { @Override public void onLocationChanged(Location location) { updateToNewLocation(location); } @Override public void onProviderDisabled(String provider) { updateToNewLocation(null); } @Override public void onProviderEnabled(String provider) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } };
定位数据保存，划线处可不要
/** * 定位数据随时保存 * @param location * @return */ private Location updateToNewLocation(Location location) { String latLongString; if (location != null) { lat = location.getLatitude(); lng = location.getLongitude(); alt = location.getAltitude(); latLongString = " 纬度:" + lat + " 经度:" + lng + " 海拔:" + alt; PDALogger.d(latLongString); mLocation = mLocation; } else { PDALogger.d("无法获取地理信息，请稍后..."); } return location; }
上面就是整个代码使用的方式了，下面是整个Service代码
