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，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。

表情解析先关 :下图是drawable文件下的表情文件


Java代码

1. static{//表情文件和表情id的对应的HashMap<String,String>
2. drawableIdToFaceName.put("h000","调皮");
3. drawableIdToFaceName.put("h001","呲牙");
4. drawableIdToFaceName.put("h002","惊讶");
5. drawableIdToFaceName.put("h003","难过");
6. drawableIdToFaceName.put("h004","酷");
7. drawableIdToFaceName.put("h005","冷汗");
8. drawableIdToFaceName.put("h006","抓狂");
