Get image from web with URI

Question

What is wrong with this code. It does not give an error but no image can be seen

ImageView a= (ImageView) findViewById(R.id.imageView1);

String imageBaseDirectory = "www.dha.com.tr/newpics/news/";
String imageName = "230620111356175716857.jpg";
a.setImageURI(Uri.parse(imageBaseDirectory+imageName)); 

Answer 1

First, you should add http:// at the beginning of you URI:

Uri uri = Uri.parse("http://www.dha.com.tr/newpics/news/230620111356175716857.jpg");

ImageView does not support loading images from remote locations. Only resources or files on local file system. In your case you should see warning in LogCat:

You should download the image yourself and then specify local path for setImageURI.

Answer 2

Try using

a.setImageBitmap(BitmapFactory.decodeStream(new URL(imageBaseDirectory+imageName).openConnection().getInputStream()));

as suggested in the Android documentation.
