如何在android中构造Webview应用的自定义User Agent字符串？

import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;

public class MainActivity extends AppCompatActivity {

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

        WebView webView = findViewById(R.id.webView);
        WebSettings webSettings = webView.getSettings();

        // 设置自定义的User Agent字符串
        String customUserAgent = "MyCustomUserAgent/1.0";
        webSettings.setUserAgentString(customUserAgent);

        // 加载网页
        webView.loadUrl("https://www.example.com");
    }
}
