android 短信查询、头像、联系人名称(支持会话和短信)__接上篇
来源：互联网 发布：尼泊尔弯刀数据图纸 编辑：程序博客网 时间：2024/06/06 07:32
背景描述
对于查询短信的功能，上篇文章已经有了初步的结果和显示。
但是有一个严重的问题就是，一直在嵌套查询。
如果会话列表有100个，那我就需要查询其他对应的表一百次。。。三个表就是三百次
会相当耗时并且一直占用数据库
为了更快的拿到数据，我的想法是一次性从表中拿到所有的数据，然后这时候只需要查询四次；然后自己根据id或者唯一标示进行数据的拼装
代码

如果有更好的想法，欢迎留言交流，虽然我不经常写，但是看见的话一定会回复的 emmm~~渣渣程序员慢慢爬中。。。
