Fit image in webview

Question

Hi, I am planning to display images from SD card in a webview in order to take advantage of he built in zoom capabilities of webview. However, I am facing an issue with displaying images that are bigger than screen size (e.g. 1800x1200) to fit the screen initially, like in an ImageView. I want the image to be displayed in full at first and provide zoom control to the users. I have tried using WRAP_CONTENT for webview's width and height, but that does not work. Any ideas? Following is a code snippet I am using:

    String path = getRealPathFromURI(mUriList.get(0)); // this gets the file path
    webView = (WebView) findViewById(R.id.WebView01);
 WebSettings settings= webView.getSettings();
 settings.setBuiltInZoomControls(true);
 settings.setSupportZoom(true);     
 webView.loadUrl("file://" + path);
