android – Connecting JS to WebView

Question:

There is a page with a structure

<head></head>
<body>
<div id="container">
<div id="header"></div>
<div id="main"></div>
</div>
</body></html>

How can I hide <div id="header"></div> and everything inside it in the browser?

   public class HelloWebViewClient 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:document.getElementsById(header).style.display = 'none'; ");
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_lichkab);
        //


        //
        mWebView.getSettings().setJavaScriptEnabled(true);
        //
        mWebView.loadUrl("https://tetrapolis.handybank.ru/");
        //mWebView.getSettings().setLoadsImagesAutomatically(false);
        mWebView.getSettings().setLoadWithOverviewMode(true);
        mWebView.getSettings().setUseWideViewPort(true);
        mWebView.setWebViewClient(new HelloWebViewClient());
    }

Answer:

Use evaluateJavascript function?

Read the documentation? 😀

True, there is a nuance – this is for kit kata only.

For earlier versions, I think, you need to download html, add a script there, and send it to the view.
