使用WebView实现新浪微博OAuth登录
?
#新浪官方下载SDK(weibo4android)
http://open.weibo.com/wiki/index.php/SDK
?
#申请应用KEY
登录新浪微博，进入http://open.weibo.com/申请应用，获取KEY和SECRET。
?
#准备
在项目中导入commons-httpclient-3.x.jar并加入weibo4android、weibo4android.http、weibo4android.org.json、weibo4android.util包文件(这些都是官方下载的SDK提供的文件)
?
在跳转到新浪微博授权页面时会使用默认浏览器，这个不太好看，也有些用户手机用其他如UC等浏览器。因此，我决定用WebView代换默认浏览器。
默认浏览器
?
WebView代换
?
在我的项目中，有多个应用项目需要OAuth登录，因此需要做成共通，也考虑到应用今后可能会支持如腾讯微博、人人网、支付宝等多种方式登录，所以我的代码考虑了“开-闭原则”。
