I'm just starting to try to figure it out too, and it seems unnecessarily tricky.

Here's a working method to add NEW spannable text to an existing view. I wanted to add colored text to a view, and this seemed like the only way to do it.

Though it feels like an ugly hack, you can create a dummy TextView (not shown anywhere) and style the text there, then append that styled text to wherever you want. Credit for it goes to iifuzz at anddev.org. My code looks like so:

    spanbuffer = new TextView(context);
    spanbuffer.setText(newText, TextView.BufferType.SPANNABLE);
    Spannable s = (Spannable) spanbuffer.getText();
    s.setSpan(new ForegroundColorSpan(Color.RED), 0, newText.length() - 1, 0);
    this.append(s);

I think you're supposed to be able to create new spannable text using the SpannableFactory, like so:

    Spannable s = Spannable.Factory.getInstance().newSpannable(newText);

but I couldn't get this text to actually show new span effects, so I gave up.
