在android中使用socket.io时，如何在运行时获取视图？

implementation 'io.socket:socket.io-client:4.0.1'

import io.socket.client.IO;
import io.socket.client.Socket;

public class MainActivity extends AppCompatActivity {
    private Socket socket;

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

        try {
            socket = IO.socket("http://your-socket-server.com");
            socket.connect();
        } catch (URISyntaxException e) {
            e.printStackTrace();
        }
    }
}

socket.on("message", new Emitter.Listener() {
    @Override
    public void call(Object... args) {
        final String message = (String) args[0];

        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                TextView textView = findViewById(R.id.textView);
                textView.setText(message);
            }
        });
    }
});

runOnUiThread(new Runnable() {
    @Override
    public void run() {
        TextView textView = findViewById(R.id.textView);
        textView.setText(message);
    }
});
