[android-developers] Re: Why does getPadding() of NinePatchDrawable throw a NullPointerException?
Ah! That works fine, thank you very much. As to why I was creating a NinePatchDrawable my self... I can only claim inexperience with the NinePatch classes. :) This is how it looks now, after your comments: Bitmap tagBalloonBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.balloon); NinePatchDrawable tagBalloon9pDrawable = new NinePatchDrawable(tagBalloonBitmap, tagBalloonBitmap.getNinePatchChunk(), new Rect(0,0,0,0), null); // Anders On 13 Okt, 00:01, Romain Guy romain...@google.com wrote: BTW, why are you creating the NinePatchDrawable yourself if you are creating it from a resource anyway?

I very very strongly recommend not creating a nine patch yourself; just use Resources.getDrawable() to create it. On Tue, Oct 13, 2009 at 12:02 AM, Anders sundman.and...@gmail.com wrote: Ah!

[android-developers] Re: Why does getPadding() of NinePatchDrawable throw a NullPointerException?
I didn't know about that method, but that sounds like the right solution. I was kind of suspecting that there would be a cleaner solution to all of this.

NinePatchDrawable tagBalloon9pDrawable = new NinePatchDrawable(tagBalloon9p); this creates a NinePatchDrawable with a null padding. That's why you get an NPE. You need to specify the padding.
