Question

I have a Gallery view in my application which is working fine. When clicking on a Gallery item, I’m displaying the full image in an ImageView. When the activity is first loaded, I want to display the first image in the full image’s ImageView programmatically, so that the user doesn’t have to click the first item in the Gallery.

— Edit —-

public void onCreate() {
//other code

    ga = (Gallery)findViewById(R.id.photo_gallary);
    imageView = (ImageView)findViewById(R.id.gallary__full_img);

    ga.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            displayFullImg(arg2);               
        }           
    });


ga.setAdapter(new ImageAdapter(this));
ga.setSelection(0);
}//onCreate

private void displayFullImg(int arg2){
  Item item = pics.get(arg2);
  String url = item.getImageUri();
  imageView.setImageBitmap(url);
}

You can use directly

imageView.setImageBitmap(pics.get(0).getImageUri());
