如何使用定位工具在android中获取移动设备的当前纬度和经度?
How do I get the current Latitude and Longitude of the mobile device in android using location tools?
推荐答案
使用 LocationManager.
LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
double longitude = location.getLongitude();
double latitude = location.getLatitude();
对 getLastKnownLocation() 的调用不会阻塞 - 这意味着如果当前没有可用位置,它将返回 null - 所以你可能想看看将 LocationListener 传递给 requestLocationUpdates() 方法,它将为您提供位置的异步更新.
The call to getLastKnownLocation() doesn't block - which means it will return null if no position is currently available - so you probably want to have a look at passing a LocationListener to the requestLocationUpdates() method instead, which will give you asynchronous updates of your location.
private final LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
longitude = location.getLongitude();
latitude = location.getLatitude();
}
}
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2000, 10, locationListener);
您需要为您的应用程序提供 ACCESS_FINE_LOCATION 权限 如果你想使用 GPS.
You'll need to give your application the ACCESS_FINE_LOCATION permission if you want to use GPS.
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
您可能还想添加 ACCESS_COARSE_LOCATION 当 GPS 不可用时的权限 并使用 getBestProvider() 方法.
You may also want to add the ACCESS_COARSE_LOCATION permission for when GPS isn't available and select your location provider with the getBestProvider() method.
