嗨,我想添加一個進度條到我的活動,不知道如何做到這一點。這裏是場景: 我的活動消息調用IMSERVICE.SENDFILE(),我將消息的上下文作爲參數傳遞給IMSERVICE.SENDFILE()。 IMSERVICE.SENDFILE()調用SOCKETOPERATOR.SENDFILE()。我也通過相同的背景。現在安卓進度條

public boolean sendFile(Context c,String path,String ip, int port) { 
     // TODO Auto-generated method stub 


     try { 


      String[] str = ip.split("\\."); 

      byte[] IP = new byte[str.length]; 

      for (int i = 0; i < str.length; i++) { 

       IP[i] = (byte) Integer.parseInt(str[i]); 


      } 
      Socket socket = getSocket(InetAddress.getByAddress(IP), port); 
      if (socket == null) { 
       Log.i("SO sendFILE",""); 

       return false; 
      } 
      Log.i("SocketOP", "sendFILE-1"); 
      File f = new File(path); 
      String filename=path.substring(path.lastIndexOf("/")+1); 
      System.out.println("filename:"+filename); 
      fin.filename = "~"+filename; 
      BufferedOutputStream out = new BufferedOutputStream(socket.getOutputStream()); 

      FileInputStream fileIn = new FileInputStream(f); 
      Log.i("SocketOP", "sendFILE-2"); 
      byte [] buffer = new byte [(int)f.length()]; 
      System.out.println("SO sendFile f.length();" + f.length()); 
      int bytesRead =0; 



      ProgressDialog pbarDialog = new ProgressDialog(c); 
      pbarDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); 
      pbarDialog.setMessage("Loading..."); 
      pbarDialog.setCancelable(false); 
      pbarDialog .setProgress(0); 
      pbarDialog.show(); 
       while ((bytesRead = fileIn.read(buffer)) > 0) { 
           out.write(buffer, 0, buffer.length); 
        //get the previous value of progress bar 
           int old_value = pbarDialog .getProgress(); 
           //calculate how much did you read from the file 
           int new_read =(int)(((float) f.length()/bytesRead)*100); 
           //add the new read to the old_value 
           int value = new_read+old_value; 
           pbarDialog.setProgress(value); 
           Log.i("SocketOP", "sendFILE-3"); 

        System.out.println("SO sendFile" + bytesRead +filename); 
          } 
      pbarDialog.dismiss(); 







      out.flush(); 
      out.close(); 
      fileIn.close(); 






     } catch (IOException e) { 
      return false;   
      //e.printStackTrace(); 
     } 
     // Toast.makeText(this, "Lvbvhhging...", Toast.LENGTH_SHORT).show(); 

     return true;  
    } 

,你可以看到我有它一個進度:SOCKETOPERATOR.SENDFILE()具有發送文件的方法和看起來像這樣。我不知道如何使它從我的消息活動中顯示出來。另外,我不知道我是否正確使用了progressDilog。任何人都可以幫忙嗎?

這是第三次你問這個問題。爲什麼? – Michele

因爲它而掙扎。在我最後的帖子上有人說如果答案沒有幫助提出一個新問題.. –
