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。 public class AddWeiboActivity extends Activity implements OnClickListener{

myclover 写道 挺不错的啊，采用什么验证方式的呢？
呵呵，谢谢夸奖，腾讯的是基于Oauth1.0版本验证，新浪的是2.0，以前新浪支持basci用户名和密码的方式，现在已经不行了，故很多以前新浪第三方开发的都需重新开发，新浪还支持xAuth方式验证（OAuth的简化）
