  @Override

    protected void setupView() {

        mTopNavbar = (TopNavbar) findViewById(R.id.rl_top_navbar);

        mWebView = (WebView) findViewById(R.id.wv_auth);

        mWebView.setVerticalScrollBarEnabled(false);

        mWebView.setHorizontalScrollBarEnabled(false);

        mWebView.getSettings().setJavaScriptEnabled(true);

    }

b. 组拼请求参数


    StringBuilder authorizeUrl = new StringBuilder(Constant.AUTHORIZE_URL);

        authorizeUrl.append("?");

        authorizeUrl.append("client_id=").append(Constant.API_KEY);

        authorizeUrl.append("&redirect_uri=").append(Constant.DEFAULT_REDIRECT_URI);

        authorizeUrl.append("&response_type=").append("token");

        authorizeUrl.append("&display=").append("touch");

        String scope = TextUtils.join(" ", Constant.HAVE_PERMISSIONS);

        authorizeUrl.append("&scope=").append(scope);

        Log.i(TAG, "authorizeUrl = " + authorizeUrl.toString());

c. 使用WebView组件加载授权界面


 mWebView.loadUrl(authorizeUrl.toString());

        

        // 以POST方式请求

        // mWebView.postUrl(Constant.AUTHORIZE_URL, EncodingUtils.getBytes(sb.toString(), "BASE64"));

        mWebView.setWebViewClient(new WebViewClient() {



            public boolean shouldOverrideUrlLoading(WebView webView, String url) {

                Log.i(TAG, "shouldOverrideUrlLoading() Redirect URL = " + url);



                if (url.startsWith(Constant.DEFAULT_REDIRECT_URI + "#error=login_denied")) {

                    AuthActivity.this.onBackPressed();

                } else if(url.startsWith("http://graph.renren.com/oauth/login_success.html#access_token")) {

                    String accessToken = url.substring(url.indexOf("="), url.indexOf("&"));

                    Log.i(TAG, "accessToken = " + accessToken);

                    

                    AuthActivity.this.onBackPressed();

                    return false;

                }

                

                webView.loadUrl(url);

                return true;

            }



            public void onReceivedSslError(WebView view, SslErrorHandler handler, android.net.http.SslError errorCode) {

                // 在默认情况下，通过loadUrl(String url)方法，可以顺利load。

                // 但是，当load有ssl层的https页面时，如果这个网站的安全证书在Android无法得到认证，WebView就会变成一个空白页，

                // 而并不会像PC浏览器中那样跳出一个风险提示框。因此，我们必须针对这种情况进行处理。(这个证书限于2.1版本以上的Android 系统才可以)

                

                // 默认的处理方式，WebView变成空白页

                // handler.cancel(); 

                

                // 接受证书   

                handler.proceed();

            }



            @Override

            public void onReceivedError(WebView view, int errorCode,

                    String description, String failingUrl) {

                super.onReceivedError(view, errorCode, description, failingUrl);

                AuthActivity.this.onBackPressed();

            }



            public void onPageStarted(WebView view, String url, Bitmap favicon) {

                Log.i(TAG, "Webview loading URL: " + url);

                super.onPageStarted(view, url, favicon);

            }



            public void onPageFinished(WebView view, String url) {

                Log.i(TAG, "onPageFinished() url = " + url);

                super.onPageFinished(view, url);

            }

        });

d. Back键事件处理


 @Override

    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if (keyCode == KeyEvent.KEYCODE_BACK) {

            if (mWebView != null) {

                mWebView.stopLoading();

            }

        }

        return super.onKeyDown(keyCode, event);

    }
