Another option that might work for some is to use a WebView, which has built in zoom controls.

WebView webView = new WebView(this);
webView.setBackgroundColor(0xff000000);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setSupportZoom(true);
//webView.getSettings().setDisplayZoomControls(false);  // API 11
webView.loadDataWithBaseURL(null, getHtml(), "text/html", "UTF-8", null);
mainView.addView(webView, -1, -2);
