Android 我想在发送图像时显示进度条

我想通过套接字发送图像，在发送过程中，必须显示进度条，并且在发送图像时应更新进度条，但当我尝试此代码时，进度条未显示，图像正在发送。 我试过了，但进度条直接显示100，过程仍在继续，进度条显示100%

            int count;         
            try {
            //image send
            client = new Socket(ServerIP,4444);

            File file = new File(path);
            byte[] mybytearray = new byte[(int) file.length()];
            FileInputStream fis = new FileInputStream(file);
            BufferedInputStream bis = new BufferedInputStream(fis);
            //bis.read(mybytearray, 0, mybytearray.length);
            OutputStream os = client.getOutputStream();
            DataOutputStream dos = new DataOutputStream(os);     
            dos.writeUTF(file.getName()); 
            long total = 0;

            while ((count = bis.read(mybytearray)) != -1) {
                total += count;
                publishProgress(""+(int)((total*100)/file.length()));
                 os.write(mybytearray, 0, mybytearray.length);
                 //os.write(mybytearray, 0, mybytearray.length);

            }
           // os.write(mybytearray, 0, mybytearray.length);
           // os.write(mybytearray, 0, mybytearray.length);
            os.flush();
            bis.close();
            fis.close();
            client.close();

        } catch (UnknownHostException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return null;
    }

好的，请展示其余的代码，尤其是publishProgress方法。但最有可能的是，您只是忘记了调用setMax。。。当您收到第一个100字节时，它已经是100%。

很抱歉，这是发送图像的实际代码，我忘记了一件事：int count；超乎想象{语句，但如果您愿意，我将放置包含pre、post方法和progressbar详细信息的其余代码…根据您的要求，最大值应该是多少，因为我希望在发送图像时看到进度条从0%进展到100%。实际上，您实现的publishProgress函数对查看如何实际更新ProgressBar

            try {

            File file = new File(path);
            byte[] mybytearray = new byte[(int) file.length()];
            FileInputStream fis = new FileInputStream(file);
            BufferedInputStream bis = new BufferedInputStream(fis);
            //bis.read(mybytearray, 0, mybytearray.length);
            OutputStream os = client.getOutputStream();
            DataOutputStream dos = new DataOutputStream(os);     
            dos.writeUTF(file.getName()); 
            long total = 0;

            while ((count = bis.read(mybytearray)) != -1) {
                total += count;
                publishProgress(""+(int)((total*100)/file.length()));
                 os.write(mybytearray, 0, mybytearray.length);
                 //os.write(mybytearray, 0, mybytearray.length);

            }
           // os.write(mybytearray, 0, mybytearray.length);
           // os.write(mybytearray, 0, mybytearray.length);
            os.flush();
