现在，我需要它有一个“手动”位置..我试图在这里改变“loation”：
yahooWeatherUtils.queryYahooWeather(getApplicationContext(), location, this);
使用如下字符串：
yahooWeatherUtils.queryYahooWeather(getApplicationContext(), "New York", this);
但不起作用......任何想法？

在搜索YahooWeatherUtils时，我找到了http://www.codota.com/android/scenarios/52fcbdbbda0ae4ff7532748f/com.google.android.gms.location.LocationClient?tag=dragonfly
他们的建议是：
Location location = locationClient.getLastLocation();
YahooWeatherUtils ywu = YahooWeatherUtils.getInstance();
if PreferenceManager.getDefaultSharedPreferences(getActivity()).getBoolean("weatherUseCurrentLocation", true) && location != null) {
ywu.queryYahooWeather(getActivity(), location , this);
} else {
String city = PreferenceManager.getDefaultSharedPreferences(getActivity()).getString("weatherCity", "Vancouver Canada");
ywu.queryYahooWeather(getActivity(), city , this);
}
因此，似乎函数queryYahooWeather可以获得纬度/经度或城市名称。您只需要足够的城市名称信息。

如果您使用Googleplay services，则可以在没有GPS的情况下获取您的位置信息。它似乎默认为信号塔和已知的wifi位置等来源。奖金如果设备实际上有一个GPS和gps打开谷歌播放服务将使用它但它不会烦人请打开GPS，所以这将完全适合您的应用程序。第一个修复也非常快。
public class KmlReader extends ActionBarActivity implements
GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener, LocationListener
{
...
if (locationManager == null) {
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.addGpsStatusListener(this);
}
* Called by Location Services when the request to connect the client
* finishes successfully. At this point, you can request the current
* location or start periodic updates
*/
@Override
public void onConnected(Bundle dataBundle) {
if (action_track) {
if (mLocationRequest == null) {
// Create a new global location parameters object
mLocationRequest = LocationRequest.create();
// Set the update interval
mLocationRequest.setInterval(UPDATE_INTERVAL);
// Use high accuracy
mLocationRequest
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
// Set the interval ceiling to one minute
mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
}
mLocationClient.requestLocationUpdates(mLocationRequest, this);
} else {
stopLocationUpdates();
}
}
神奇的是这个位置进入了这个方法。
@Override
public void onLocationChanged(Location location) {
