主要活动＆gt;新警报＆gt;主要活动＆gt;报警和GT;新警报＆gt;线程执行错误
基本上是主要活动，我有一个带有个人适配器的ExpandableListView，它协调选项菜单;只需单击菜单报警，然后菜单子新报警，重定向到活动新报警，卷信息进入数据库并运行服务（Hilo），负责比较系统时间与介绍。

第一次成功运行到达并且两次都相等时被重定向到报警活动，该报警活动完成了应该的操作并重定向到主活动，在尝试创建或修改新的arlama以输入数据时出现问题按Pin接受线程执行错误生成，表示线程已经运行且无法再次运行。
我结束每条线都满足了我感兴趣的条件，而不是第二次运行或者如果活动重定向没有成功停止并且一些puntoo重新运行服务，也许可能是主要活动未在适配器中完成甚至虽然您控制活动并作为参数工作适配器和

activity = act;

有什么想法吗？
答案 0 :(得分：0)
AsyncTask只能使用一次。在onCreate（）中，您可以创建AsyncTask。在onStartCommand()中，您使用AsyncTask。如果再次调用onStartCommand()，它会再次尝试使用AsyncTask。这是不允许的。
在AsyncTask中创建onStartCommand()。
答案 1 :(得分：0)
最后通过调用MyService类中的方法stopActivity（）来解决问题，当我的条件满足它停止时，完成线程作为服务并正常工作。
