해서 ProgressDialog 바

Question

메신저 업로드 파일과 진행 막대를 사용하려고 메신저를 작동하지 :

@Override 
public void onClick(View v) { 
    if(v== ivAttachment){ 

     //on attachment icon click 
     showFileChooser(); 
    } 
    if(v== bUpload){ 

     //on upload button Click 
     if(selectedFilePath != null){ 
      dialog = new ProgressDialog(upload.this); 
      dialog.setMax(100); 
      dialog.setMessage("Subiendo Archivo..."); 
      dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); 
      dialog.setProgress(0); 
      dialog.show(); 

      //dialog.show(upload.this,"","Subiendo Archivo...",true); 

      new Thread(new Runnable() { 
       @Override 
       public void run() { 
        //creating new thread to handle Http Operations 
        uploadFile(selectedFilePath); 
       } 
      }).start(); 

     }else{ 
      Toast.makeText(upload.this,"Escoge un archivo",Toast.LENGTH_SHORT).show(); 
     } 

    } 
} 

다음을 UploadFile (selectedFilePath);

이

//android upload file to server

문제가 여기에 있습니다 : : 바로 여기

int totalBytesWritten = 0; 


         //loop repeats till bytesRead = -1, i.e., no bytes are left to read 
         while (bytesRead > 0) { 

          //write the bytes read from inputstream 
          dataOutputStream.write(buffer, 0, bufferSize); 
          bytesAvailable = fileInputStream.available(); 
          bufferSize = Math.min(bytesAvailable, maxBufferSize); 
          bytesRead = fileInputStream.read(buffer, 0, bufferSize); 

           totalBytesWritten += bytesRead; 


          if (dialog != null) { 
           dialog.setProgress((int)(totalBytesWritten/ totalSize * 100)); 
          } 

: 여기서 시작은 내 코드입니다

경우 (! 대화 = NULL) { dialog.setProgress ((INT) (totalBytesWritten/totalSize * 100)); }

Answer 1

에서 onCreate 또는 온 클릭에 당신이 최대 처리기 다음

Handler mMainHandler = new Handler(Looper.prepareMainLooper()); 

새 사용할 수 있어야하려는 경우

private void updateUI(){ 
    mMainHandler.post(new Runnable(){ 
     //touch dialog 
    } 
}
