(转摘)Android腾讯微博客户端开发4:微博发送篇(QQ表情,@搜索)

凌晨发帖不容易啊，? 有一个问题，谁做过android的自定义表情啊？貌似还没有发现有客户端有，都是图片，如果能像在电脑上那样自定义表情的功能多好，那位大哥知道，麻烦告知一声，呵呵。写完，睡觉。

我们仔细来观察下腾讯微博的qq表情发送规律，由/开始,1到3个中文或者英文字符.

写个工具类来测试已测试正则表达式来匹配表情。



在上方输入框中可以输入查询 格式为 @你选择的列表值

这个是话题输入界面，格式为#话题#

表情选择页面，这个其实是一个每行5列的GridView


此界面可看到你写的微博的内容，点击发送，发送成功

哈哈，看到了吧，[email protected]erson和表情的微博了。

接下来，上代码。
