以下对我来说很好。试试看。

public class YourHtmlClass extends Activity {

    private WebView mWebview;
    private ProgressDialog progressBar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.your_layout_containing_webview);
        mWebview = (WebView) findViewById(R.id.webView1);
        WebSettings settings = mWebview.getSettings();
        settings.setJavaScriptEnabled(true);
        mWebview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
        progressBar = ProgressDialog.show(AboutUsHtml.this, "", "Loading...",
                true);
        mWebview.setWebViewClient(new WebViewClient() {
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
            }

            public void onPageFinished(WebView view, String url) {
                if (progressBar.isShowing()) {
                    progressBar.dismiss();
                }
            }

            public void onReceivedError(WebView view, int errorCode,
                    String description, String failingUrl) {
                AlertDialog alert = new AlertDialog.Builder(AboutUsHtml.this)
                        .create();
                alert.setTitle("No connection"));
                alert.setIcon(R.drawable.ic_launcher);
                alert.setCancelable(false);
                alert.setMessage("No connection"));
                alert.setButton("OK", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();

                    }
                });
                alert.show();
            }
        });
        mWebview.loadUrl("Your URL Goes Here");
    }
}

我猜网址有问题。我尝试使用其他 url 进行 360 度视图并且它有效。检查这个：360度视图
