Question

我正在开发Android的小部件，它会显示您当前的位置。要获得当前的纬度和经度，我有以下代码：

public class LocationInfo extends Activity {

RemoteViews remoteViews;

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
myLocationListener locationListener = new myLocationListener();
LocationProvider locationProvider = locationManager.getProvider(LocationManager.NETWORK_PROVIDER);
locationManager.requestLocationUpdates(locationProvider, 0, 0, locationListener);

class myLocationListener implements LocationListener {

    public void onLocationChanged(Location location) {
        if(location != null)
        {
            double Long = location.getLongitude();
            double Lat = location.getLatitude();

            remoteViews.setTextViewText(R.id.widget_textview3, Double.toString(Long));
        }

        else {
            remoteViews.setTextViewText(R.id.widget_textview3, "LOADING...");
        }

    }

    public void onProviderDisabled(String arg0) {
        // TODO Auto-generated method stub

    }

    public void onProviderEnabled(String arg0) {
        // TODO Auto-generated method stub

    }

    public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
        // TODO Auto-generated method stub

    }
}
}

但是，我在requestLocationUpdates的参数中收到错误。它表示“令牌上的语法错误，而而是预期的VariableDeclarator”位于0,0，locationListener。

此外，这是一个单独的类。我怎么会在我的小部件中运行它？类似的东西：

LocationInfo locationProvider = new LocationInfo();
LocationProvider.run();

可能？再次，真的很感激任何帮助！

您不得执行

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

方法之外。只需移动到例如onCreate的Activity。
