在我的android项目中，我需要显示搜索栏和网络速度（使用FTP协议从服务器上载/下载文件的速度）。在我尝试从模拟器SD卡上传文件的情况下，当文件存储在服务器中时它会显示速度和搜索栏，但我的要求是我需要在文件上传时连续显示sheekbar和网络速度进入服务器。我不明白我的代码在哪里做错了。下面是我上传到ftp服务器的文件代码：

因为你正在调用doInBackground（），所以我假设你是AslassTask的子类。如果是这样，为什么不使用publishProgress和onProgressUpdate？ runOnUiThread不会立即执行，除非您已经 on UI线程，并且因为您在doInBackground（）中，所以您在后台线程中，而不是UI线程。在doInBackground（）结束之前，runOnUiThread（）可能实际上没有运行。相比之下，publishProgress和onProgressUpdate专门用于报告后台线程的进度。
