上程式碼先

    /**
     * 判斷服務是否執行
     * 
     * @param context
     * @param clazz
     * @return
     */
    public static boolean isRunging(Context context,
            Class<? extends Service> clazz) {

        ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        List
 
<ActivityManager.RunningServiceInfo> list = am.getRunningServices(Integer.MAX_VALUE);

        for (ActivityManager.RunningServiceInfo info : list) {
            ComponentName service = info.service;
            String className = service.getClassName();
            if (className.equals(clazz.getName())) {
                return
 
 true;
            }
        }

        return false;
    }

得到activity管理者：

ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);

  
得到所有在執行的服務：

List<ActivityManager.RunningServiceInfo> list = am.getRunningServices(Integer.MAX_VALUE);
