I want to supply a good user experience,which is dynamically display a downloading image.I mean that the bitmap should be displayed even if during the bitmap is downloaded from remote server.Some image website have this feature. For example,if I download half of bitmap data from the remote server,it can display half of the bitmap in imageview

you can use "Android-Query" Library for Display Image from Internet. Please see my this answer and follow one by one step of wiki page of Android-Query
Lazy load of images in ListView
All the information to display image is on Wiki Page. https://code.google.com/p/android-query/wiki/ImageLoading
aq.id(imageview).progress(this).image(imageUrl, true, true, **50, 0**, new BitmapAjaxCallback(){
@Override
public void callback(String url, ImageView iv, Bitmap bm, AjaxStatus status){
iv.setImageBitmap(bm);
}
});

But I think this is not suitable for my requirement,I want to display the bitmap even if during the bitmap is downloaded. for example,if I download half of bitmap data from the remote server,it can display half of the bitmap in imageview. – Crystal Jake Apr 03 '13 at 08:01

you can use **50, 0** for half display image . just need to give the size such as 70,0 or 120,0 etc. please try it – Rahul Rawat Apr 03 '13 at 08:44
