android 判断Service是不是开启

android 判断Service是否开启
被判断的Service 必须是带包名的全名

通过Service的类名来判断是否启动某个服务 

private boolean MusicServiceIsStart(List<ActivityManager.RunningServiceInfo> mServiceList,String className){                    for(int i = 0; i < mServiceList.size(); i ++){              if(className.equals(mServiceList.get(i).service.getClassName())){                  return true;              }          }          return false;      } 

 private String getServiceClassName(List<ActivityManager.RunningServiceInfo> mServiceList){          String res = "";          for(int i = 0; i < mServiceList.size(); i ++){              res+=mServiceList.get(i).service.getClassName()+ " /n";          }                    return res;      } 

ActivityManager mActivityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);List<ActivityManager.RunningServiceInfo> mServiceList = mActivityManager.getRunningServices(30);// 我要判断的服务名字，必须是带包名的全名final String musicClassName = "rod.fasdf.TService";boolean b = MusicServiceIsStart(mServiceList, musicClassName);System.out.println("服务是否开启======>"+b);
