##之间的内容是代表一个话题，@和:之间的是转发这条微博的人，也高亮显示，||代表上一次转发此微博的。url地址也高亮显示。


这个是什么组件啊？是TextView,不会吧？TextView能显示图片吗？肯定能呀。



主要是用到了SpannableString，ForegroundColorSpan，ImageSpan这3个类.

String origtext = data.getString("origtext");
                    SpannableString spannable = new SpannableString(origtext);

                    spannable = TextUtil.decorateFaceInStr(spannable, RegexUtil.getStartAndEndIndex(origtext, Pattern.compile("\\/[\u4e00-\u9fa5a-zA-Z]{1,3}")), getResources());//解析成本地表情
                    spannable = TextUtil.decorateRefersInStr(spannable, RegexUtil.getStartAndEndIndex(origtext, Pattern.compile("@.*:")), getResources());//高亮显示微薄转发，回复者昵称
