下載時顯示進度條

我想顯示一個進度條顯示完成百分比，而我的應用程序通過互聯網下載一些大文件。這樣的事情： enter image description here 下載時顯示進度條

這是自定義的。 –

你做了這個@Hieu le –

xml文件代碼：

<ProgressBar 
     android:id="@+id/xml_reg_progressBar" 
     style="?android:attr/progressBarStyleHorizontal" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginLeft="@dimen/common_left_right_margin" 
     android:layout_marginRight="@dimen/common_left_right_margin" 
     android:layout_marginTop="@dimen/reg_ph_linear_top_margin" 
     />

你可以改變風格進度按您的要求。

這是用java文件代碼：

protected static final int TIMER_RUNTIME = 180000; // in ms --> 10s 
    private ProgressBar progressTimer; 
    public void startTimer() { 
      final Thread timerThread = new Thread() { 
       @Override 
       public void run() { 
        mbActive = true; 
        try { 
         int waited = 0; 
         while (mbActive && (waited < TIMER_RUNTIME)) { 
          sleep(1000); 
          if (mbActive) { 
           waited += 1000; 

           updateProgress(waited); 
          } 
         } 
        } catch (InterruptedException e) { 
         // do nothing 
        } finally { 
         onContinue(); 
        } 
       } 

      }; 
      timerThread.start(); 

     } 

     Handler handler = new Handler(); 

     private void onContinue() { 
      handler.post(new Runnable() { 
       @Override 
       public void run() { 

        txtCallContactUsNumber 
          .setText(CommonVariable.CallForSupporMessage 
            + contactInfo.MobileNo); 

       } 
      }); 

     } 

     public void updateProgress(final int timePassed) { 
      if (null != progressTimer) { 
       // Ignore rounding error here 
       final int progress = progressTimer.getMax() * timePassed 
         /TIMER_RUNTIME; 
       handler.post(new Runnable() { 
        @Override 
        public void run() { 
         Log.i("timePassed", "timePassed=" + timePassed); 

         DateFormat formatter = new SimpleDateFormat("mm:ss"); 
         Calendar calendar = Calendar.getInstance(); 
         calendar.setTimeInMillis(timePassed); 
         String timer = formatter.format(calendar.getTime()); 
         formatter.setTimeZone(java.util.TimeZone.getTimeZone("GMT")); 
         txtTimerCount.setText(formatter.format(timePassed)); 
        } 
       }); 

       progressTimer.setProgress(progress); 
      } 
     }

在我的代碼，這將調用1秒，得到進步增量每隔1秒。
