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

<uses-permission android:name="android.permission.CAMERA" />//相机权限<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />//写SD<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />//读SD<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTE" />

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);/*** API24 以上调用* @param context* @param imageFile* @return*/Uri getImageContentUri(Context context, File imageFile);}
