Android系统服务：LocationManager

本文主要是介绍Android系统服务：LocationManager，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

系统定位

需要权限：

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

获取LocationManager

LocationManager lm = (LocationManager) getSystemService(LOCATION_SERVICE);

设置参数和监听

lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3000, 100, listener);

 * 第一个参数：定位类型* 第二个参数：定位时间间隔* 第三个参数：定位距离间隔* 第四个参数：监听

当第3个参数不为0时，以第3个参数为依据；当第三个参数为0，已第2个参数为依据。

定位类型:(6.0上测试失败，没有获取到坐标，即使把targetSdkVersion改成22,；5..1上测试成功。)

LocationManager.GPS_PROVIDER
LocationManager.NETWORK_PROVIDER
LocationManager.PASSIVE_PROVIDER

LocationListener listener = new LocationListener() {@Overridepublic void onLocationChanged(Location location) {//获取到坐标LogUtil.d("onLocationChanged" + location.getProvider() + "," + location.getLongitude() + "," + location.getLatitude() + ","+ location.getTime() + "," + location.getAltitude());}@Overridepublic void onStatusChanged(String provider, int status, Bundle extras) {//GPS状态变化时触发LogUtil.d("onStatusChanged," + provider + "," + status);}@Overridepublic void onProviderEnabled(String provider) {//GPS开启时触发LogUtil.d("onProviderEnabled," + provider);}@Overridepublic void onProviderDisabled(String provider) {//GPS关闭时触发LogUtil.d("onProviderDisabled," + provider);}
};

`AndroidUtilCode`的`LocationUtils`

是否打开了GPS:

LocationUtils.isGpsEnabled()

LocationUtils.register(0, 0, new LocationUtils.OnLocationChangeListener() {@Overridepublic void getLastKnownLocation(Location location) {LogUtil.d("getLastKnownLocation," + location.getLatitude() + "," + location.getLongitude());}@Overridepublic void onLocationChanged(Location location) {LogUtil.d("onLocationChanged," + location.getLatitude() + "," + location.getLongitude());}@Overridepublic void onStatusChanged(String provider, int status, Bundle extras) {LogUtil.d("provider=" + provider + ",status=" + status);}
});LocationUtils.unregister();
