MVP模式的Android 调用系统拍照，相册，剪裁，适配到7.0,修复拍照图片旋转问题
Android 调用系统拍照，相册，剪裁，适配到7.0,修复拍照图片旋转问题
直接上代码
首先添加拍照需要的权限
使用的常量
public static final int MY_PERMISSIONS_REQUEST_CAMERA = 100;//拍照权限
public static final int MY_PERMISSIONS_REQUEST_READ_SD= 101;//读SD卡权限
public static final int MY_PERMISSIONS_REQUEST_WRITE_SK = 102;//写SD卡权限
public static final int MY_PERMISSIONS_REQUEST_READ_SD_PHOTOALBUM= 103;//写SD卡权限
public static final int MY_PERMISSIONS_REQUEST_WRITE_SK_PHOTOALBUM = 104;//写SD卡权限
public static final int CAPTURE_IMAGE_REQUEST = 104;//拍照后的返回值
public static final int LOAD_IMAGE_REQUEST = 105;//相册的返回值
public static final int CLIP_IMAGE_REQUEST = 106;//剪裁图片的返回值
public static final String IMAGE_TYPE = "image/*";
public static File mOutFile;//图片uri路径
public static File mImageFile=null;//图片file路径
public static Integer mBuildVersion=android.os.Build.VERSION.SDK_INT;//当前SDK版本
定义需要用到的接口
public interface UserCenterModel {
/**
* 拍照
* @param context
*/
void getFileByPhotograph(Context context);
/**
* 相册
* @param context
*/
void getFileByPhotoAlbum(Context context);
/**
* 创建img文件
* @return
*/
File getImagefile();
/**
* 开始拍照
* @param context
*/
void startPhotograph(Context context);
/**
* 调用相册
* @param context
*/
void startPhotoAlbum(Context context);
/**
* 剪裁图片
* @param activity
*/
void startClip(Activity activity, File file);
/**

* @return
*/
Uri getImageContentUri(Context context, File imageFile);
