你必须调用startService()为你的服务正确注册和传递BIND_AUTO_CREATE是不够的。

Intent bindIntent = new Intent(this,ServiceTask.class);
startService(bindIntent);
bindService(bindIntent,mConnection,0);

现在是ServiceTools类:

public class ServiceTools {
    private static String LOG_TAG = ServiceTools.class.getName();

    public static boolean isServiceRunning(String serviceClassName){
        final ActivityManager activityManager = (ActivityManager)Application.getContext().getSystemService(Context.ACTIVITY_SERVICE);
        final List<RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);

        for (RunningServiceInfo runningServiceInfo : services) {
            if (runningServiceInfo.service.getClassName().equals(serviceClassName)){
                return true;
            }
        }
        return false;
     }
}

我的kotlin转换ActivityManager::getRunningServices基于答案。把这个函数放在一个活动中-

private fun isMyServiceRunning(serviceClass: Class<out Service>) =
    (getSystemService(ACTIVITY_SERVICE) as ActivityManager)
        .getRunningServices(Int.MAX_VALUE)
        ?.map { it.service.className }
        ?.contains(serviceClass.name) ?: false

     }
}

检测服务是否正在运行的唯一有效/最快/干净的方法是创建PING/PONG功能。

在服务内部实现Messenger或AIDL方法:isAlive()——它返回服务的状态。

不要实现广播，因为它们可能被错过。

另一种方法是使用kotlin。启发了其他用户的回答

fun isMyServiceRunning(serviceClass: Class<*>): Boolean {
    val manager = getSystemService(Context.ACTIVITY_SERVICE) as ActivityManager
    return manager.getRunningServices(Integer.MAX_VALUE)
            .any { it.service.className == serviceClass.name }
}

作为kotlin扩展

fun Context.isMyServiceRunning(serviceClass: Class<*>): Boolean {
    val manager = this.getSystemService(Context.ACTIVITY_SERVICE) as ActivityManager
    return manager.getRunningServices(Integer.MAX_VALUE)
            .any { it.service.className == serviceClass.name }
}

使用

context.isMyServiceRunning(MyService::class.java)

/**
 * Check if the service is Running 
 * @param serviceClass the class of the Service
 *
 * @return true if the service is running otherwise false
 */
public boolean checkServiceRunning(Class<?> serviceClass){
    ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE))
    {
        if (serviceClass.getName().equals(service.service.getClassName()))
        {
            return true;
        }
    }
    return false;
}
