Here are a couple of methods for creating a
Drawable
or a
Bitmap
from a web url:
/** Returns a Drawable object containing the image located at 'imageWebAddress' if successful, and null otherwise.
* (Pre: 'imageWebAddress' is non-null and non-empty;
* method should not be called from the main/ui thread.)*/
public static Drawable createDrawableFromUrl(String imageWebAddress)
{
Drawable drawable = null;
try
{
InputStream inputStream = new URL(imageWebAddress).openStream();
drawable = Drawable.createFromStream(inputStream, null);
inputStream.close();
}
catch (MalformedURLException ex) { }
catch (IOException ex) { }
return drawable;
}
/** Returns a Bitmap object containing the image located at 'imageWebAddress'
* if successful, and null otherwise.
* (Pre: 'imageWebAddress' is non-null and non-empty;
* method should not be called from the main/ui thread.)*/
public static Bitmap createBitmapFromUrl(String imageWebAddress)
{
Bitmap bitmap = null;
try
{
InputStream inputStream = new URL(imageWebAddress).openStream();
bitmap = BitmapFactory.decodeStream(inputStream);
inputStream.close();
}
catch (MalformedURLException ex) { }
catch (IOException ex) { }
return bitmap;
}
