在我的地图应用程序,我不似乎越来越位置更新,我上了车,并开始驾驶周围,但我的位置标记从未改变在地图上,甚至给了我一个null lat and long locationManager = (LocationManager) this.getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
例如 var query = myDic.Where(x => !blacklist.Contains(x.Key));
foreach (var item in query)
{
if (condition)
blacklist.Add(item.key+1); //key is int type
ret.add(item);
