　　　　//WebChromeClient主要處理解析，渲染網頁等瀏覽器做的事情

　　　　//WebChromeClient是輔助WebView處理Javascript的對話方塊，網站表徵圖，網站title，載入進度等 

        webView.setWebChromeClient(new WebChromeClient() //遊覽器        {            @Override            public boolean onJsAlert(WebView view, String url, String message, JsResult result) //對話方塊            {//                result.confirm();//                return true;                return super.onJsAlert(view, url, message, result);            }            @Override            public void onReceivedTitle(WebView view, String title)  //標題            {                super.onReceivedTitle(view, title);                                WebBrowserActivity.this.title.setText(title);            }                    });                }    @Override    protected void onDestroy()    {        super.onDestroy();    }    @Override    public boolean onKeyDown(int keyCode, KeyEvent event)  //按鍵響應    {        if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack())         {             webView.goBack();             return true;         }                 return super.onKeyDown(keyCode, event);     }    @Override    protected void onPause()    {        super.onPause();    }    @Override    protected void onRestart()    {        super.onRestart();    }    @Override    protected void onResume()    {        super.onResume();    }            }
