仿微信查找聊天记录自动搜索关键字

该数据库为本地数据库：

 private void search() { roomChartList.clear(); if (!TextUtils.isEmpty(iv_search_value.getText())) { ll_chat_record.setVisibility(View.GONE); mlistView.setVisibility(View.VISIBLE); String condition = String.valueOf(iv_search_value.getText()); roomChartList = roomChatService.queryByCondition(mUser.getId(), roomId, "%" + condition + "%");//通过调用数据库进行模糊查找 if (roomChartList != null && roomChartList.size() > 0) { tv_text.setVisibility(View.GONE); findTheChatRecordAdapter = new FindTheChatRecordAdapter(context, roomChartList); mlistView.setAdapter(findTheChatRecordAdapter); } else { 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 tv_text.setText(style); tv_text.setVisibility(View.VISIBLE); } } else { mlistView.setVisibility(View.GONE);//隐藏搜索列表 tv_text.setVisibility(View.GONE);//隐藏提示文字显示 ll_chat_record.setVisibility(View.VISIBLE);//显示群成员，日期 roomChartList = roomChatService.queryByRoomId(mUser.getId(), roomId); if (roomChartList != null && roomChartList.size() > 0) { findTheChatRecordAdapter = new FindTheChatRecordAdapter(context, roomChartList); mlistView.setAdapter(findTheChatRecordAdapter); } } }
