android的自定义表情

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，我的微博首页已经显示了我刚才发送的带有话题@person和表情的微博了。


接下来，上代码。
