判断某个服务是否正在运行的工具类

public class ServiceRunManager {
    
        public static boolean isServiceRunning(Context context) {
            boolean isRunning = false;
    
            ActivityManager activityManager = (ActivityManager) context
                    .getSystemService(Context.ACTIVITY_SERVICE);
            List<ActivityManager.RunningServiceInfo> serviceList = activityManager
                    .getRunningServices(Integer.MAX_VALUE);
    
    
            if (serviceList == null || serviceList.size() == 0) {
                return false;
            }
    
    
            for (int i = 0; i < serviceList.size(); i++) {
                if (serviceList.get(i).service.getClassName().equals(MyService.class.getName())) {
                    isRunning = true;
                    break;
                }
            }
            return isRunning;
        }
    }

方法使用

if (ServiceRunManager.isServiceRunning(MainActivity.this)) {
                        Log.e(MyService.class.getSimpleName(), "在运行");
                    } else {
                        Log.e(MyService.class.getSimpleName(), "不在在运行");
                    }

把上面的Manager 变成单例的方法

public class ServiceRunManager {
    
        public static ServiceRunManager serviceRunManager = null;
    
        private ServiceRunManager() {
    
        }
    
        public static ServiceRunManager getInstance() {
            if (serviceRunManager == null) {
                serviceRunManager = new ServiceRunManager();
            }
            return serviceRunManager;
        }
    
        public boolean isServiceRunning(Context context) {
            boolean isRunning = false;
    
            ActivityManager activityManager = (ActivityManager) context
                    .getSystemService(Context.ACTIVITY_SERVICE);
            List<ActivityManager.RunningServiceInfo> serviceList = activityManager
                    .getRunningServices(Integer.MAX_VALUE);
    
    
            if (serviceList == null || serviceList.size() == 0) {
                return false;
            }
    
    
            for (int i = 0; i < serviceList.size(); i++) {
                if (serviceList.get(i).service.getClassName().equals(MyService.class.getName())) {
                    isRunning = true;
                    break;
                }
            }
            return isRunning;
        }
    }

单例的使用

if (ServiceRunManager.getInstance().isServiceRunning(MainActivity.this)) {
                        Log.e(MyService.class.getSimpleName(), "在运行");
                    } else {
                        Log.e(MyService.class.getSimpleName(), "不在在运行");
                    }
