从 webView Android Studio 中的 google fileViewer 中删除配置选项

Question

我正在使用 webView 中的谷歌驱动器文件查看器在我的应用程序中显示谷歌驱动器文件。 fileViewer 在顶部显示一个带有文件名和登录选项的栏，在底部显示一个带有一些选项的栏。

是否可以隐藏顶栏和底栏？

我认为可以通过AndroidStudio中的javascript来做到这一点，但我不知道该怎么做

这是带有 webView 的电话屏幕：

这是我在 Android Studio 上显示 webview 的代码：

  private WebView webView;


    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_edit);

        String fileId = "1HHNdVFfGSnLLXsvpN5ITEktsdNENLT-jYl1guyNqgZw";
        String url = "https://docs.google.com/file/d/" + fileId + "/view";
        initializeWebViewer(url);
    }

    @SuppressLint("SetJavaScriptEnabled")
    public void initializeWebViewer(String url) {

        webView = (WebView) findViewById(R.id.webViewViewer);

        Log.i("url", url);

        webView.setWebViewClient(new MyWebViewClient());
        WebSettings webViewSettings = webView.getSettings();
        webViewSettings.setJavaScriptCanOpenWindowsAutomatically(true);
        webViewSettings.setJavaScriptEnabled(true);
        webView.loadUrl(url);


    }

    public class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            return false;
        }
    }

我使用 devTools 从手机页面获取代码（我认为它在 html 中，我是新手，如果我混淆了 javascript、html 或其他内容，请见谅）检查它”并删除代码以查看它是否真的是我想要的：

我认为这是 devTools 中的顶部栏元素（如果我删除它就会消失）：

我设法使用隐藏顶部栏

webView.loadUrl("javascript:(function() { " +
                    "document.getElementsByClassName('ndfHFb-c4YZDc-Wrql6b-SmKAyb')[0].style.display='none'; })()");
