I further improved mvandillen class.

This seems to work very fine:

public class RoundedBackgroundSpan extends ReplacementSpan
    {
        private final int mPadding = 10;
        private int mBackgroundColor;
        private int mTextColor;

        public RoundedBackgroundSpan(int backgroundColor, int textColor) {
            super();
            mBackgroundColor = backgroundColor;
            mTextColor = textColor;
        }

        @Override
        public int getSize(Paint paint, CharSequence text, int start, int end, Paint.FontMetricsInt fm) {
            return (int) (mPadding + paint.measureText(text.subSequence(start, end).toString()) + mPadding);
        }

        @Override
        public void draw(Canvas canvas, CharSequence text, int start, int end, float x, int top, int y, int bottom, Paint paint)
        {
            float width = paint.measureText(text.subSequence(start, end).toString());
            RectF rect = new RectF(x, top+mPadding, x + width + 2*mPadding, bottom);
            paint.setColor(mBackgroundColor);
            canvas.drawRoundRect(rect, mPadding, mPadding, paint);
            paint.setColor(mTextColor);
            canvas.drawText(text, start, end, x+mPadding, y, paint);
        }
    }
