[置顶] Android通过访问相机或相册来更换头像

 首先 我们实现的是点击头像   出现一个dialog   选择相机或是相册 来选择照片进行头像更换   这样  由于是自己写的项目  我把有关更换头像的这个class的全部代码都贴在这儿  代码我都备注上了   然后大家自己捡着有用的几个方法  去写  我都有说明  下面看代码

上面的 代码很简单  弹出dialog  三个 按钮 相机 相册  取消  这里xml文件我就不写了   很简单 。。希望对大家有帮助

 有一点  sdk版本要22   因为22以上 有的手机调试 相机调不出来  大家注意一下 大家不要忘了把权限加上哦，，，
