在登陸介面獲取驗證碼的時候:

new Thread(){
            @Override
            public void run() {
                try {
                    SharedPreferences spf = getSharedPreferences("Cookie", Context.MODE_PRIVATE);

                    HttpClient client = new DefaultHttpClient();
                    HttpGet get = new HttpGet(Gloable.DOLOAD
 
+"code.gif");
                    HttpResponse response = client.execute(get);
                    Cookie cookie = ((AbstractHttpClient) client).getCookieStore().getCookies().get(0);
                    String sessionId = cookie.getValue();
                    SharedPreferences.Editor editor = spf.edit

                    editor.putString("sessionId", sessionId);
                    String cookieString = cookie.getName()+"="+cookie.getValue()+
                            ";domain="+cookie.getDomain();
                    Log.e("test", "cookieString:"+cookieString);
                    editor.putString
 
("cookieString", cookieString);
                    editor.commit();
                    Log.i("info", "b--JSESSIONID=" + sessionId);
                    if (response.getStatusLine().getStatusCode() == 200) {
                        byte[] bytes = EntityUtils.toByteArray(response.getEntity());
                        final Bitmap bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
                        runOnUiThread(new Runnable() {
                            public void run() {

                                iv_showCode.setBackgroundDrawable(drawable);
                            }
                        });
                    }
                } catch (ClientProtocolException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }.start();

在webview載入url之前:

SharedPreferences spf = getSharedPreferences("Cookie", Context.MODE_PRIVATE);
        CookieSyncManager.createInstance(this);
        CookieManager cookieManager = CookieManager.getInstance();
        String cookieString = spf.getString("cookieString", "");
        cookieManager.setCookie(url, cookieString);
        CookieSyncManager.getInstance().sync();

        webview.loadUrl(url);
