title: Android Help with adding a progress dialog while image loading?
body: <p>I have been following a tutorial that remotely downloads an image to an imageview, but i'm not sure how to add a progress dialog (image or something) to show the user that image is downloading, instead of just a blank screen.</p>
  
  <p>Hope someone can help</p>
  
  <pre><code> ImageView imView;
   String imageUrl="http://domain.com/images/";
   Random r= new Random();

      super.onCreate(icicle);
  
      this.requestWindowFeature(Window.FEATURE_NO_TITLE);
      this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN ,
              WindowManager.LayoutParams.FLAG_FULLSCREEN );
  
      setContentView(R.layout.galleryshow);
  
      Button bt3= (Button)findViewById(R.id.get_imagebt);
      bt3.setOnClickListener(getImgListener);
      imView = (ImageView)findViewById(R.id.imview);
