进度条 - 没有信息只是加载栏

我的问题是：

如何删除该弹出进度条上显示的文本/信息，所以ONY的yelow吧？

另外，我可以将颜色从黄色更改为蓝色吗？

public class MainActivity extends Activity { 

Button btnStartProgress; 
ProgressDialog progressBar; 
private int progressBarStatus = 0; 
private Handler progressBarHandler = new Handler(); 

private long fileSize = 0; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main_activity); 

    addListenerOnButton(); 

} 

public void addListenerOnButton() { 

    btnStartProgress = (Button) findViewById(R.id.button1); 
    btnStartProgress.setOnClickListener(
      new OnClickListener() { 

     @Override 
     public void onClick(View v) { 

     // progress bar dialog 
     progressBar = new ProgressDialog(v.getContext()); 
     progressBar.setCancelable(true); 
     progressBar.setMessage("Progress Bar ... "); 
     progressBar.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); 
     progressBar.setProgress(0); 
     progressBar.setMax(100); 
     progressBar.show(); 

     //reset progress bar status 
     progressBarStatus = 0; 

     //reset filesize 
     fileSize = 0; 

     new Thread(new Runnable() { 
      public void run() { 
      while (progressBarStatus < 100) { 

       // process some tasks 
       progressBarStatus = Tasks(); 


       try { 
       Thread.sleep(1000); 
       } catch (InterruptedException e) { 
       e.printStackTrace(); 
       } 

       // Update the progress bar 
       progressBarHandler.post(new Runnable() { 
       public void run() { 
        progressBar.setProgress(progressBarStatus); 
       } 
       }); 
      } 

      // progress 100% 
      if (progressBarStatus >= 100) { 

       // sleep 2 seconds, so that you can see the 100% 
       try { 
        Thread.sleep(2000); 
       } catch (InterruptedException e) { 
        e.printStackTrace(); 
       } 

       // close the progress bar dialog 
       progressBar.dismiss(); 
      } 
      } 
      }).start(); 

      } 

      }); 

    } 

public int Tasks() { 

    while (fileSize <= 1000000) { 

     fileSize++; 

     if (fileSize == 100000) { 
      return 10; 
     } else if (fileSize == 200000) { 
      return 20; 
     } else if (fileSize == 300000) { 
      return 30; 
     } else if (fileSize == 500000) { 
      return 50; 
     } else if (fileSize == 900000) { 
      return 90; 
     } 

    } 

    return 100; 

}}

我发现关于两个漂亮的教程：

TUT2

对于ProgresDialog的定制，检查this。还有：

<style name="pbStyle" parent="android:Theme.Dialog"> 
<item name="android:textColor">#FFFFFFFF</item> 
<item name="android:background">#FF0000FF</item> 
<item name="android:windowBackground">@android:color/transparent</item> 
</style>
