android真实项目教程（七）——梦醒边缘花落_by_CJJ

大家下午好，我是CJJ，说说昨晚挑灯夜写毕业论文到凌晨三点多，当写到致谢词那块时，我违心的写下：“本论文在xxx导师的悉心指导和亲切关怀下完成的。导师渊博的专业知识、严谨的治学态度，精益求精的工作作风，诲人不倦的高尚师德，严于律己、宽以待人的崇高风范，朴实无法、平易近人的人格魅力对本人影响深远。。。。。。”其实，我就只见了指导老师一面而已。。。。转回正题，写的这个app,就只剩下SlideMenuFragment这块还没有任何东西 ，那么我们就填充它把。。。。

主要加入了两个功能：（1）设置头像，可以从相册选择，也可以相机拍摄；（2）ExpandableListView展开，item标明个功能模块。
效果如下图：
