Camera、
	1.权限设置
	2.intent、startActivityForResult启动照相
	3.onActivityResult 接收照相的返回值
		3.1、数据图片保dsdcard
		3.2、读取sdcard图片
		3.3、图片加载到imageView上
	4.点击图片；popupwindow或者新页面放大展示

	照相机拍照需要的权限：
<!--写sd卡权限-->
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 <!--读sd卡的权限 -->
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<!--操作摄像头的权限 -->
   <uses-permission android:name="android.permission.CAMERA" />
