要配置Android原生定位服務(wù)LocationManager,首先需要在AndroidManifest.xml文件中添加以下權(quán)限:

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

接著在代碼中獲取LocationManager實(shí)例并配置定位參數(shù),例如:

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);
criteria.setSpeedRequired(false);
criteria.setCostAllowed(true);

String provider = locationManager.getBestProvider(criteria, true);

然后可以通過LocationManager注冊監(jiān)聽器來獲取位置更新:

LocationListener locationListener = new LocationListener() {
    @Override
    public void onLocationChanged(Location location) {
        //處理位置更新
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {}

    @Override
    public void onProviderEnabled(String provider) {}

    @Override
    public void onProviderDisabled(String provider) {}
};

locationManager.requestLocationUpdates(provider, 0, 0, locationListener);

最后不要忘記在適當(dāng)時(shí)候停止定位服務(wù):

locationManager.removeUpdates(locationListener);

以上就是配置Android原生定位服務(wù)LocationManager的基本步驟。根據(jù)實(shí)際需求,可以進(jìn)一步配置定位參數(shù)和優(yōu)化定位精度。
