How to populate dynamically created imageview through urls asyncronously…In Android

问题

I am using horizontal pager

https://github.com/ysamlan/horizontalpager/blob/master/src/com/github/ysamlan/horizontalpager/HorizontalPager.java

to make dynamic views,and making dynamic images in it....

And using fedor imageloader to pupulate imageviews from urls... https://github.com/thest1/LazyList/blob/master/src/com/fedorvlasov/lazylist/ImageLoader.java

but i am getting that annoying stid image.... here is my code...

Any help or suggestion will be highly appropriated

Thanx in advance

public class testing extends Activity {

private HorizontalPager mPager;
 ImageView[] image;

 String url = "http://icons-search.com/img/icons-land/IconsLandVistaStyleEmoticonsDemo.zip/IconsLandVistaStyleEmoticonsDemo-PNG-256x256-Cool.png-256x256.png";

 @Override
 public void onCreate(final Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.testing);
  ImageLoader imageLoader = new ImageLoader(this);
  mPager = (HorizontalPager) findViewById(R.id.horizontal_pager);

  image = new ImageView[2];
  for (int i = 0; i < 2; i++) {

   image[i] = new ImageView(getApplicationContext());
   image[i].setImageResource(R.drawable.logo_background);
   RelativeLayout.LayoutParams layoutParams90 = new RelativeLayout.LayoutParams(
     225, 250);
   layoutParams90.leftMargin = 25;
   image[i].setLayoutParams(layoutParams90);
   mPager.addView(image[i]);

  }

  for (int i = 0; i < 2; i++) {
   imageLoader.DisplayImage(url, image[i]);
  }
 }

}

回答1:

When you create ImageView try to pass your Activity instead of Application context. So replace this

image[i] = new ImageView(getApplicationContext());

with this

image[i] = new ImageView(this);

回答2:

Please check whether you added external storage and internet permission in your android manifest file?

You need to localize the problem first. Probably there's something wrong with the url you use - try another one. Probably something related to Pager - try without pages, just put all images into LinearLayout. What else may be a problem - just find some clue. Does it work if you just put a single ImageView to the screen?
