第一阶段冲刺

觅踪1

昨天主要是对正则表达式的学习，今天家里的杂物比较多，忙活了一下午，晚上适当的做了一些按钮，为刚开始的登录注册页面做准备，睡了睡了

觅踪2

昨天的页面设计受到了停滞，今天换了一种形式，之前是直接用按键绘制，现在改为代码操纵，自己的进程缓慢了许多，明天将继续加油

界面代码如下：

复制代码

今天整体结束了登录界面的构造搭建，并且开始了下一阶段，也就是个人信息以及好友的功能开发整体来说，由于对于Android Studio的不熟练，开发进程略微嫌慢，后期慢慢的会加快进程

冲刺阶段过半，开了一次小会，明确了第一阶段的冲刺目标，互相之间加油打气，队内相互鼓励，活跃了一下氛围

个人的登录功能的构建也日趋完善，期间也会有一些小问题，相互讨论，并在一些教程以及CSDN论坛的帖子中寻找解决问题的方法

登录功能的完成，既是加油打气，也是开启新任务的连接。接下来，铆足气力攻克难关，研究地图可视化、定位功能以及路线的可视化

由于大家都没有接触过，也有向也一些学长请教，但还是无果

于是转向CSDN论坛，看了些前辈发布的关于调用Baidu、高德地图API的经验

觅踪7

经过昨天的学习、交流、讨论，对于地图的调用有了初步的了解认知，但是总体来说还是有些欠缺

开发的初期就遇到了一些问题，比如Baidu密钥的获取，SHA1指纹的获取

这里附上其中的一个较为详细的CSDN论坛的路径：

https://blog.csdn.net/Ivan_Keung/article/details/53819406

感觉还不错步骤还是挺详细的

觅踪8

距离冲刺结束还有两天，今天我们在CSDN论坛的帖子的步骤教学下，进行了临摹，先尝试着自己开发，但是经过了一天的奋斗之后，我们好像遇到了瓶颈，于是又召开了一次会议重新制定了目标，决定脚踏实地，明天先尝试着将帖子上的代码运行出来，再进行修改，学习把他转化成为我们自己的代码

觅踪9

按着昨天预想的步骤来走，其实不然，我们似乎遇到了大问题

在一步一步跟着帖子的指示下来，就在我们准备run的时候

他报错了，没错报错了，这是我们没有想到的

觅踪10

终于，在最后一天，初步实现了地图的可视化，虽然与我们预想的结果有些偏差，但总算是有了些进展

以上是关于第一阶段冲刺的主要内容，如果未能解决你的问题，请参考以下文章
