Android腾讯微博客户端开发六:给用户加VIP认证以及美化微博显示内容

哈哈，通过VIP标志看到赵薇是冒牌的，李开复和冯小刚是正品。 
 
##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

public static List<Map<String,Object>> getStartAndEndIndex(String sourceStr,Pattern pattern){
        List<Map<String,Object>> list = new ArrayList<Map<String,Object>>();
        Matcher matcher = pattern.matcher(sourceStr);
        boolean isFind = matcher.find();
        while (isFind) {
            Map<String,Object> map = new HashMap<String, Object>();
            String faceName = matcher.group().substring(1,matcher.group().length());//表情名称
            map.put("startIndex",matcher.start());
            map.put("endIndex",matcher.end());
            map.put("faceName",faceName);
            list.add(map);
            isFind = matcher.find((Integer)map.get("endIndex")-1);
        }
        return list;
    }

public static SpannableString decorateVipInStr(SpannableString spannable,List<Map<String,Object>> list,Resources resources){
        int size = list.size();
        Drawable drawable = null;
        if(list!=null&&list.size()>0){
            for(int i=0;i<size;i++){
                Map<String,Object> map = list.get(i);
                drawable = resources.getDrawable(R.drawable.vip);
                drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),drawable.getIntrinsicHeight());
                ImageSpan span = new ImageSpan(drawable,ImageSpan.ALIGN_BASELINE);
                spannable.setSpan(span, (Integer)map.get("startIndex"), (Integer)map.get("endIndex"), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            }
        }
        return spannable;
    }

    public static SpannableString decorateTopicInStr(SpannableString spannable,List<Map<String,Object>> list,Resources resources){
        int size = list.size();
        Drawable drawable = null;
        CharacterStyle foregroundColorSpan=new ForegroundColorSpan(Color.argb(255, 33, 92, 110));
        if(list!=null&&list.size()>0){
            for(int i=0;i<size;i++){
                Map<String,Object> map = list.get(i);
                spannable.setSpan(foregroundColorSpan, (Integer)map.get("startIndex"), (Integer)map.get("endIndex"), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            }
        }
        return spannable;
    }
