每个表情对应一个字符串，像这样
public class SmileUtils {
public static final String ee_1 = "[):]";
public static final String ee_2 = "[:D]";
public static final String ee_3 = "[;)]";
}
我的TextView设置文本（表情也是文本），是这样的
holder.message.setText(SmileUtils.getSmiledText(getContext(), getMessageDigest(lastMessage, (this.getContext()))), BufferType.SPANNABLE);
getSmiledText（）是这样的
public static Spannable getSmiledText(Context context, CharSequence text) {
Spannable spannable = spannableFactory.newSpannable(text);
addSmiles(context, spannable);
return spannable;
}
