Android WebView zoom controls only with image not html

I am working on an android app with a webview element and local html pages and images.

When a link goes to and image (example: images/image.png) I want to let the user zoom in and out.

But I don't want the zoom to work on the html pages.

This is why webView.getSettings().setBuiltInZoomControls(true); doesn't work for me.

Any suggestions?

You could specify user-scalable=no on your viewport to disable user scaling. See here for more on the viewport tag.

The answer was simple actually.

        webView.setWebViewClient(new WebViewClient()
    {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url)
        {
            String fileEx = url.substring(Math.max(0, url.length() - 3));

            if(fileEx.equals("jpg")){
                webView.getSettings().setBuiltInZoomControls(true);
            }else{
                webView.getSettings().setBuiltInZoomControls(false);
            }

            view.loadUrl(url);
            return true;
        }
    });

Simplest solution would be to call webView.getSettings().setBuiltInZoomControls(true); when the link goes to the image and webView.getSettings().setBuiltInZoomControls(false); when the users back to main html
