推荐答案

Google Maps API 位置现在可以使用了，甚至还有监听器，你可以使用它来实现，例如:

The Google Maps API location now works, even has listeners, you can do it using that, for example:

private GoogleMap.OnMyLocationChangeListener myLocationChangeListener = new GoogleMap.OnMyLocationChangeListener() {
    @Override
    public void onMyLocationChange(Location location) {
        LatLng loc = new LatLng(location.getLatitude(), location.getLongitude());
        mMarker = mMap.addMarker(new MarkerOptions().position(loc));
        if(mMap != null){
            mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f));
        }
    }
};

然后为地图设置监听器:

and then set the listener for the map:

mMap.setOnMyLocationChangeListener(myLocationChangeListener);

这将在地图首次找到位置时调用.

This will get called when the map first finds the location.

根本不需要 LocationService 或 LocationManager.

No need for LocationService or LocationManager at all.

OnMyLocationChangeListener 接口已弃用.使用 com.google.android.gms.location.FusedLocationProviderApi 代替.FusedLocationProviderApi 提供改进的位置查找和电源使用，并由我的位置"蓝点使用.请参阅示例应用程序文件夹中的 MyLocationDemoActivity 以获取示例代码或位置开发人员指南.

OnMyLocationChangeListener interface is deprecated. use com.google.android.gms.location.FusedLocationProviderApi instead. FusedLocationProviderApi provides improved location finding and power usage and is used by the "My Location" blue dot. See the MyLocationDemoActivity in the sample applications folder for example example code, or the Location Developer Guide.
