To increase the space between the captions of the subfloats, one way is to add margin=<length> as an option to the subfig package, e.g.
\usepackage[margin=10pt]{subfig}
But this adds the margin to both sides of the caption. The package has many options for customizing the caption in that way, see the manual.
If you do not want fig. 2.2a, 2.2b, but fig. 2.2, 2.3, you can use two minipages within the figure environment:
\begin{figure}
\begin{minipage}{0.45\textwidth}
\centering
\includegraphics{a}
\caption{Caption A}
\end{minipage}\hfill
\begin{minipage}{0.45\textwidth}
\centering
\includegraphics{b}
\caption{Caption B}
\end{minipage}\hfill
\end{figure}
I hope that this is the one you want
code
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{figure}
\begin{center}
\includegraphics[width=0.35\textwidth]{albt.png}
\vspace{1cm}
\includegraphics[width=0.35\textwidth]{altman.png}
\vspace{0.1cm}
\caption{ActionButton}
\label{ActionButton}
\end{center}
\end{figure}
\end{document}

There's no gap between images. The gap is due to the size of each image inside every subfigure.
In Gonzalo's answer, every subfigure occupies half text line, but the image inside every subfigure only uses 40% of available space. This creates the gap.
Following code shows the original answer and another where images inside subfigure use the whole available space. And there is no gap!
