在前面我写了两篇关于QQ和微信的分享（http://blog.csdn.net/dawanganban/article/details/42015249）（http://blog.csdn.net/dawanganban/article/details/40478317）这一篇我们来看以怎样实现微博分享功能。

微博的參考文档在开放平台上转悠了半天，没有找到，终于才惊奇的发如今SDK的Demo中。还是我的老思路，遇到这样的第三方接入的最快最好的入手点就是入门文档和官方Demo,打开Demo我们就会看到相关文档和源代码，因为前面的APPID的申请和QQ、微信差点儿相同，所以我在这里就不反复了，能够參考一下上面的两篇文章。

接下来我就将我封装好的源代码粘出来例如以下：

public class SinaShareManager{	/**	 * 文字	 */	public static final int SINA_SHARE_WAY_TEXT = 1;	/**	 * 图片	 */	public static final int SINA_SHARE_WAY_PIC = 2;	/**	 * 链接	 */		public static final int SINA_SHARE_WAY_WEBPAGE = 3;		private static String sinaAppKey;	public static final String SCOPE = 	            "email,direct_messages_read,direct_messages_write,"	            + "friendships_groups_read,friendships_groups_write,statuses_to_me_read,"	            + "follow_app_official_microblog," + "invitation_write";    /** 微博分享的接口实例 */    private IWeiboShareAPI sinaAPI;        public void registSina(Context context){    	//获取appkey    	if(sinaAppKey == null){    		sinaAppKey = SinaShareUtil.getSinaAppKey(context);    	}    	//初始化微博分享代码    	if(sinaAppKey != null){    		initSinaShare(context);    	}    }	/**	 * 新浪微博分享方法	 * @param shareContent 分享的内容	 */	public void shareBySina(ShareContent shareContent, Context context){		if(sinaAPI == null) return;		switch (shareContent.getShareWay()) {		case SINA_SHARE_WAY_TEXT:			shareText(shareContent);			break;		case SINA_SHARE_WAY_PIC:			sharePicture(shareContent, context);			break;		case SINA_SHARE_WAY_WEBPAGE:			shareWebPage(shareContent, context);			break;		}	}		/*	 * 分享文字	 */	private void shareText(ShareContent shareContent){		//初始化微博的分享消息		WeiboMessage weiboMessage = new WeiboMessage();		weiboMessage.mediaObject = getTextObj(shareContent.getContent());		//初始化从第三方到微博的消息请求		SendMessageToWeiboRequest request = new SendMessageToWeiboRequest();		request.transaction = buildTransaction("sinatext");		request.message = weiboMessage;		//发送请求信息到微博。唤起微博分享界面		sinaAPI.sendRequest(request);	}		/*	 * 分享图片	 */	private void sharePicture(ShareContent shareContent, Context context){		WeiboMessage weiboMessage = new WeiboMessage();		weiboMessage.mediaObject = getImageObj(shareContent.getPicResource(), context);		//初始化从第三方到微博的消息请求		SendMessageToWeiboRequest request = new SendMessageToWeiboRequest();		request.transaction = buildTransaction("sinatext");		request.message = weiboMessage;		//发送请求信息到微博，唤起微博分享界面		sinaAPI.sendRequest(request);	}		private void shareWebPage(ShareContent shareContent, Context context){		WeiboMessage weiboMessage = new WeiboMessage();		weiboMessage.mediaObject = getWebpageObj(shareContent, context);		//初始化从第三方到微博的消息请求		SendMessageToWeiboRequest request = new SendMessageToWeiboRequest();		request.transaction = buildTransaction("sinatext");		request.message = weiboMessage;		//发送请求信息到微博，唤起微博分享界面		sinaAPI.sendRequest(request);	}		/**	 * 欢迎关注-阳光小强-http://blog.csdn.net/dawanganban	 * @author lixiaoqiang	 *	 */	private abstract class ShareContent{		protected abstract int getShareWay();		protected abstract String getContent();		protected abstract String getTitle();		protected abstract String getURL();		protected abstract int getPicResource();	}		/**	 * 设置分享文字的内容	 * @author Administrator	 *	 */	public class ShareContentText extends ShareContent{		private String content;				/**		 * 构造分享文字类		 * @param text 分享的文字内容		 */		public ShareContentText(String content){			this.content = content;		}		@Override		protected String getContent() {			return content;		}		@Override		protected String getTitle() {			return null;		}		@Override		protected String getURL() {			return null;		}		@Override		protected int getPicResource() {			return -1;		}		@Override		protected int getShareWay() {			return SINA_SHARE_WAY_TEXT;		}			}		/**	 * 设置分享图片的内容	 * @author Administrator	 *	 */	public class ShareContentPic extends ShareContent{		private int picResource;		public ShareContentPic(int picResource){			this.picResource = picResource;		}				@Override		protected String getContent() {			return null;		}		@Override		protected String getTitle() {			return null;		}		@Override		protected String getURL() {			return null;		}		@Override		protected int getPicResource() {			return picResource;		}		@Override		protected int getShareWay() {			return SINA_SHARE_WAY_PIC;		}	}		/**	 * 设置分享链接的内容	 * @author Administrator	 *	 */	public class ShareContentWebpage extends ShareContent{		private String title;		private String content;		private String url;		private int picResource;		public ShareContentWebpage(String title, String content, 				String url, int picResource){			this.title = title;			this.content = content;			this.url = url;			this.picResource = picResource;		}		@Override		protected String getContent() {			return content;		}		@Override		protected String getTitle() {			return title;		}		@Override		protected String getURL() {			return url;		}		@Override		protected int getPicResource() {			return picResource;		}		@Override		protected int getShareWay() {			return SINA_SHARE_WAY_WEBPAGE;		}			}	    /**     * 创建文本消息对象。

String.valueOf(System.currentTimeMillis()) : type + System.currentTimeMillis(); } }
