Question

我创建了一个用于下载我已经完成的模块文件的应用程序！该应用程序运行良好！我正在尝试在文本视图中显示从FTP服务器下载的活动文件。但我无法显示超过3条消息。我创建计时器，当应用程序下载文件时，计时器STOP在10秒......并在2m30sec下载所有文件后重新启动....为什么??? 在IF条件下启动班次中的所有消息都很好......但是其他消息都不起作用！我需要帮助...我发布了我的部分代码和我需要做的事情。感谢大家回复！

吉拉：我们已经为钻井人员创建了一个应用程序。此应用程序连接到模块以下载文件。一天结束后，司钻将执行停止班次。我们想在他开始和停止他的班次时向司钻显示一条消息。 StartShift 1017 - 1032的行动 StopShift 1035 - 1063的行动

我创建了一个textview来向用户显示应用程序的活动。 textView的名称：textViewDuration。

1 - 我们需要在此textview中显示文件下载。在DashBoardActivity.java的第794和846行喜欢：“正在下载：nameOfFile”

2 - 我们需要在此textview中显示上传文件名称。在FtpMultiUploadTask.java的第195,265和329行喜欢：“上传：nameOfFile”

我不知道为什么，我只能显示3条消息。在DashBoardActivity的第1026行... textViewDuration.setText（“发送'T'文件”）; 在DashBoardActivity的第1134行... textViewDuration.setText（“下载所有文件......请等待”）; 并在DashBoardActivity的第1208行重置为空... textViewDuration.setText（“”）;

一旦应用程序显示这3条消息，它就不会显示其他消息。我在活动下载，FtpMultiUpload或停止班次上执行的所有setText都不起作用。 DashBoardActivity的第1035行，第1047行，第1049行，第1052行，第1054行，第1057行。当下载和上传文件时，我需要帮助来更改TextView的文本。

图片＃1：这是我打开应用程序的时候图2：当我按开始转换... textView更改...但计时保持为0！图3：计时器从0:05开始，文本改变了......但我不向用户显示文件名...不是请等待:) 图4：当所有文件下载时，文本视图消失...我按停止班次，但文本视图从不再显示，计时停止图＃5：完成所有任务后，计时器重置为0，准备开始其他任务！
