团队冲刺第六天
1.今天完善了一下。地图定位界面功能。理想的是实现倒计时之后进行跑步。之后出现了一些问题今天可虽然不多但另外有考试。总体的编写时间不是很长。新增的布局代码如下以及相关的效果图：

2.今天完成了闹钟的添加功能，过程还算顺利，但是在最后实现长按删除闹钟事件的使用遇到了问题，无法实现长按删除，由于在闹钟列表里使用了Switch开关控件，所以我感觉和这个有关系，于是拿掉了Switch控件测试了一下，果然实现了长按删除，具体什么原因还不清楚，打算明天解决，然后再美化一下界面啥的。

3.今天已经全部完成从手机本地SD卡中读取歌曲信息，并实现了音乐的播放，暂停，上一首，下一首的功能。鉴于明天满课，所以明天打算把这个音乐播放的布局完整一下，并把一些显示信息的纰漏和不完整的信息弄好。
