我正在处理一个Android项目，在这个项目中，我必须打开一个Word Online文档，该文档必须在不暴露URL的情况下打开。我有以下打开文档的代码，但是发生了一些错误。我很确定这与权限有关，但我不确定我到底遗漏了什么。

代码语言：javascript
复制
FrameLayout.LayoutParams rl = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT);
                android.webkit.WebView wView = new android.webkit.WebView(this.getContext());
                wView.setId(0x100);
                //wView.setWebChromeClient(new WebChromeClient());
                wView.setWebViewClient(new WebViewClient());
                wView.getSettings().setJavaScriptEnabled(true);
                wView.getSettings().setAllowFileAccess(true);
                wView.getSettings().setAllowUniversalAccessFromFileURLs(true);
                wView.getSettings().setAllowContentAccess(true);
                wView.getSettings().setAppCacheEnabled(true);
                wView.getSettings().setAppCachePath(getContext().getCacheDir().getPath());

                wView.setScrollContainer(false);
                wView.setLayoutParams(rl);
                wView.loadUrl(docURL);

这是显示视图时的日志

尽管我已经检查了所有的webview设置并赋予了非常广泛的权限，但这似乎是错误所在

你可以通过另一种方式使用WebView和谷歌文档实现这一点，如下所示。

代码语言：javascript
复制
String url = "http://docs.google.com/gview?embedded=true&url="+YOUR_DOC_URL;

private void loadWebViewAndDocUrl()
{
    String googleDocViewer = "<iframe src=\""+url+"\" style=\"width:100%; height:100%;\" frameborder=\"0\" allowtransparency=\"true\"></iframe>";
    progressBar = (ProgressBar) view.findViewById(R.id.progressBar);
    final WebView wvExternalLink = (WebView) view.findViewById(R.id.wvExternalLink);
    wvExternalLink.getSettings().setJavaScriptEnabled(true);

    wvExternalLink.loadData(googleDocViewer, "text/html", "utf-8");

    wvExternalLink.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            wvExternalLink.loadUrl(url);
            return true;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            // Show progress till url loads completely using progressbar
        }
    });


}

你可以试一试

代码语言：javascript
复制
WebView urlWebView = (WebView)findViewById(R.id.containWebView);
urlWebView.setWebViewClient(new AppWebViewClients());
urlWebView.getSettings().setJavaScriptEnabled(true);
urlWebView.getSettings().setUseWideViewPort(true);
urlWebView.loadUrl("http://docs.google.com/gview?embedded=true&url="
                + "YOUR_DOC_URL_HERE"); 

public class AppWebViewClients extends WebViewClient {



    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);

    }
}

你应该试着在平板电脑的浏览器上打开docURL，最好是Chrome浏览器。

你的代码适用于三星Galaxy J7 Pro，Android8.1和Moto G4，Android7.0上的this文档。两个物理设备。而且它没有显示URL。

它还可以在模拟安卓Nexus 5 API 23上工作，也就是安卓6.0。

您需要的唯一权限是：

<uses-permission android:name="android.permission.INTERNET" />

确保您的平板电脑上的Android WebView是最新的。

这也可能是DNS设置、文档内容或文档域的问题。我为我的测试创建了指向文件、->、共享、->、插入博客或站点的链接，并将内容作为生成的iframe的src属性。
