Answer 1

So my experience you should use onReceivedTitle and onPageFinished both. I find that sometimes onPageFinished you won't get notify if you front end using react-router or something similar. And onReceivedTitle has flaw as @michael-levy mentioned.

Answer 2

private WebViewClient mWvClient = new WebViewClient() {

        @Override
        public void doUpdateVisitedHistory(WebView view, String url, boolean isReload) {

            String title = view.getTitle();//getTitle
            super.doUpdateVisitedHistory(view, url, isReload);
        }
    }

Answer 3

My observation is that, you get the webpage title using WebChromeClient in lesser time than using WebViewClient

webview.setWebChromeClient(new WebChromeClient() {
    @Override
    public void onReceivedTitle(WebView view, String title) {
        super.onReceivedTitle(view, title);
        if (!TextUtils.isEmpty(title)) {
            YourActivity.this.setTitle(title);
        }
    }
});

Answer 4

What if you do not want the whole title, and just a Domain Name, Like if you want to show only 'Google' from www.google.com, and you have all the query parameters in this title.

    URL hostUrl= new URL(webView.getUrl());
    String title = hostUrl.getHost();
    title = title.startsWith("www.") ? title.substring(4) : title;

Answer 5

You'll have to use a custom WebViewClient to get this done. You will override the onPageFinished() method so when a new page finishes loading you can set the webview to the appropriate title.

Below is a sample implementation of the above:

    WebView mWebView = (WebView) findViewById(R.id.mwebview);
    mWebView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageFinished(WebView view, String url) {
            ExperimentingActivity.this.setTitle(view.getTitle());
        }
    });

You're a going to do that where you're initializing your webview. Replace the "ExperimentingActivity" to whatever you activity's name is.

If you're already overriding the WebViewClient, just add this function or the code inside to your already existing function.
