仿微信查找聊天记录自动搜索关键字

private void search() {

roomChartList = roomChatService.queryByCondition(mUser.getId(), roomId, "%" + condition + "%");//通过调用数据库进行模糊查找

String content = "没有找到" + "“";
SpannableStringBuilder style = new SpannableStringBuilder(content + condition + "”" + "相关结果");//style代表要显示的全部字符串
style.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.limegreen)), content.length() , condition.length() + content.length(),Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);//content.length()代表从第几个字符开始变颜色，注意第一个字符序号是0． // condition.length() + content.length()代表变色到第几个字符
