Answer 1

我想有問題的URL。 我試圖用360度視圖的其他網址，它的工作。 選中此項：360 degree view

Answer 2

以下工作適合我。嘗試一下。

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"); 
    } 
}
