hello, I have a webview, how can I find out which link was clicked in this webview?

Just use this code snippet. :)

private class MyWebViewClient extends WebViewClient {
    
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                String link = url + "?header=0";
                Log.d("getUrl", link);
                view.loadUrl(link);
                return false;
            }
    
        }

Example:

public class NewsDetail extends AppCompatActivity {

    WebView newsdetail;
    RelativeLayout navigation_icon;
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.news_detail);

        navigation_icon = findViewById(R.id.navigation_icon);

        newsdetail = findViewById(R.id.newsdetail);
        newsdetail.loadUrl(getIntent().getStringExtra("newsdetail"));
        newsdetail.setWebViewClient(new MyWebViewClient());
        WebSettings webSettings = newsdetail.getSettings();
        webSettings.setJavaScriptEnabled(true);
        

    }

    private class MyWebViewClient extends WebViewClient {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            String link = url + "?header=0";
            Log.d("getUrl", link);
            view.loadUrl(link);
            return false;
        }

    }

}

Note: If the header parameter is allowed by the backend, it does not show the header in the application. To be able to use it I guess it must also be allowed by the backend. Like the header=0 parameter, as in the example.
