Android实现微博分享及其注意事项
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）这一篇我们来看以如何实现微博分享功能。
微博的参考文档在开放平台上转悠了半天，没有找到，最终才惊奇的发现在SDK的Demo中，还是我的老思路，遇到这种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码，由于前面的APPID的申请和QQ、微信差不多，所以我在这里就不重复了，可以参考一下上面的两篇文章。接下来我就将我封装好的源码粘出来如下：
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);
}
