个人认为的oauth2.0的步骤：
1、打开webView 加载授权地址，就是用来登录用户名和密码的
它会带上一些参数

参数名	必选	介绍
client_id	true	申请组件时获得的API Key
response_type	true	此值固定为“token”
redirect_uri	true	授权后要回调的URI，即接受code的URI。对于无Web Server的应用，其值可以是“oob”。

2、用户登录成功，就调转到你传过去的redirect url地址上去，并且将token等信息加载url参数上
3、最后，第三方sdk会处理上面的连接地址，并返回json给一个你事先写好的listenre上去

例如
1、新浪微博登录

08-30 16:59:40.660: D/Weibo-WebView(29417): onPageStarted URL: https://open.weibo.cn/oauth2/authorize?client_id=935437242&response_type=token&redirect_uri=http%3A%2F%2Fsns.whalecloud.com%2Fsina2%2Fcallback&display=mobile

08-30 17:01:28.245: D/Weibo-WebView(29417): Redirect URL: http://sns.whalecloud.com/sina2/callback#access_token=2.00ZsX5_C9xzSBB6ee1796d9bcwObtB&remind_in=295109&expires_in=295109&uid=2118866155

传给WeiboAuthListener的实现类

String mWeiboToken = values.getString("access_token");
String expires_in = values.getString("expires_in");
String mWeiboUid = values.getString("uid");

2、qq登录

08-30 16:36:42.696: D/TDialog(27989): Webview loading URL: https://openmobile.qq.com/oauth2.0/m_authorize?status_userip=10.84.237.103&scope=get_user_info%2Cget_simple_userinfo&redirect_uri=auth%3A%2F%2Ftauth.qq.com%2F&cancel_display=1&switch=1&display=mobile&status_version=15&status_os=4.0.4&sdkv=1.6&need_pay=1&pf=openmobile_android&response_type=token&status_machine=HTC+Desire+S&sdkp=a&client_id=100326440

08-30 16:41:28.325: D/TDialog(27989): Redirect URL: auth://tauth.qq.com/?#ret=0&pay_token=694012467C7773BC946CA675404D5888&pf=openmobile_android&appid=100326440&expires_in=7776000&openid=E89F8E54945A5FA46BFB7E09C3BFB5CF&pfkey=c5ec906abca224266e90579c16a7b40d&access_token=E27530D86EACBD8E6662493240AC7906

传给IUiListener的实现类

08-30 16:41:30.097: I/System.out(27989): {"ret":"0","pay_token":"694012467C7773BC946CA675404D5888","pf":"openmobile_android","appid":"100326440","openid":"E89F8E54945A5FA46BFB7E09C3BFB5CF","expires_in":"7776000","pfkey":"c5ec906abca224266e90579c16a7b40d","access_token":"E27530D86EACBD8E6662493240AC7906"}

3、facebook
