How to add a button to open the site?

Question

Android

There is a WebViwe object, by default it displays the google.com page. How to add a button so that when you click on it, in the same WebViwe object, the yandex.ru page opens?

Answer 1

webView.loadUrl(" https://ya.ru ")
Instead of a button, I would add a menu item to "..." (top-right corner)

Answer 2

public class MainActivity extends AppCompatActivity {
    private WebView webView;

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

        Button butacc = findViewById(R.id.butacc);
        butacc.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                webView.loadUrl("http://ya.ru");
            }
        });
