Question

我想知道哪种方法最适合使用Google Play服务获取绝对最准确的当前坐标。是否使用getLastLocation()，如此：

public class MainActivity extends FragmentActivity implements
        GooglePlayServicesClient.ConnectionCallbacks,
        GooglePlayServicesClient.OnConnectionFailedListener {
    ...
    // Global variable to hold the current location
    Location mCurrentLocation;
    ...
    mCurrentLocation = mLocationClient.getLastLocation();
    ...
}

或使用更新回调，如下所示：

public class MainActivity extends FragmentActivity implements
        GooglePlayServicesClient.ConnectionCallbacks,
        GooglePlayServicesClient.OnConnectionFailedListener,
        LocationListener {
    ...
    // Define the callback method that receives location updates
    @Override
    public void onLocationChanged(Location location) {
        // Report to the UI that the location was updated
        String msg = "Updated Location: " +
                Double.toString(location.getLatitude()) + "," +
                Double.toString(location.getLongitude());
        Toast.makeText(this, msg, Toast.LENGTH_SHORT).show();
    }
    ...
}

有什么想法吗？

getLastLocation()并不保证是您当前的位置，如果您对最准确的当前位置感兴趣，那么即使您最感兴趣的位置更新也是您最好的选择
