Answer 1

I have used a workaround and it worked properly for me.

First i convert the string to bitmap and then convert it to a drawable, here is the code:

byte [] encodeByte=Base64.decode(":",Base64.DEFAULT);
Bitmap bitmap=BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);      
Drawable d = new BitmapDrawable(bitmap);

Hope it helps!

Answer 2

try  {

    InputStream inputStream = new URL(Your imageWebAddress).openStream();

    drawable = Drawable.createFromStream(inputStream, null);
    inputStream.close();
  }
  catch (MalformedURLException ex) { }
  catch (IOException ex) { }
  layout.setBackground(drawable);

Answer 3

Short: No, you can't.

Long: The notification needs a R.drawable.something for the icon and you can't create it on runtime.

Answer 4

you can make your own custom drawable that would work just like the textview widget except it is a drawable instead of a view. The textview class is just a container for the drawable that contains the text.

Answer 5

Have you looked at the API Demos > App > Notifications > Status Bar?

If you have limited number of String options (like Smileys) you can create drawables for each of those Strings.

Answer 6

No you can not, I thought you could use the same method as here: Combine image and text to drawable, but you can't, as the notification takes a drawable id, not a drawable object.
