ProgressDialog的用法示例

1.新建Android项目 ProgressDialog    在包andorid.huada下建文件ProgressDialogActivity.java

2.ProgressDialogActivity.java代码如下

  

   

    

     

    
    

     

      package android.huada;
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      import android.app.Activity; 
     
    
   

    

     

    
    

     

      import android.app.ProgressDialog; 
     
    
   

    

     

    
    

     

      import android.os.Bundle; 
     
    
   

    

     

    
    

     

      import android.os.Handler; 
     
    
   

    

     

    
    

     

      import android.os.Message;
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      public class ProgressDialogActivity extends Activity
     
    
   

    

     

    
    

     

      {
