Android WebView: display only some part of website

Question

I wanted to know if it was possible to display only certain parts of a website in a WebView. For example I have this website with the following html:

Answer 1

The most basic thing to understand here is whether the element we are referring to inside the web html file is a class or a id. If it is a id then getElementById works perfectly. If it is a class then getElementsByClassName is required.

Following is an example that I am using.

myWebView.loadUrl
      ("javascript:(function() { " +
           "document.getElementsByClassName('header_wrapper')[0].style.display='none'; " +
           "document.getElementsByClassName('footer-contact')[0].style.display='none'; "+
           "document.getElementsByClassName('navbar-header')[0].style.display='none'; "+
           "document.getElementsByClassName('footer-social')[0].style.display='none'; "+
           "document.getElementById('footer_bottom').style.display='none'; "+
           "document.getElementById('footer_content').style.display='none'; "+
           "document.getElementById('core_mobile_menu').style.display='none'; "+
           "document.getElementById('catapult-cookie-bar').style.display='none'; "+
       "}
      )()");

Answer 2

You can do this by extending WebViewClient and injecting some javascript which will render your web Page

public class MyWebClient extends WebViewClient {

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
    view.loadUrl(url);
    return true;
}

@Override
public void onPageFinished(WebView view, String url) {
    view.loadUrl("javascript:your javascript");
}
}
.........
final MyWebClient myWebViewClient = new MyWebClient();
mWebView.setWebViewClient(myWebViewClient);

For hiding elements use view.loadUrl("javascript:document.getElementById(id).style.display = 'none';)
