MVP模式的Android 呼叫系統拍照，相簿，剪裁，適配到7.0,修復拍照圖片旋轉問題

Android 呼叫系統拍照，相簿，剪裁，適配到7.0,修復拍照圖片旋轉問題
直接上程式碼
首先新增拍照需要的許可權
<uses-permission android:name="android.permission.CAMERA" />//相機許可權 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />//寫SD <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />//讀SD <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTE" />
使用的常量
public static final int MY_PERMISSIONS_REQUEST_CAMERA = 100;//拍照許可權 public static final int MY_PERMISSIONS_REQUEST_READ_SD= 101;//讀SD卡許可權 public static final int MY_PERMISSIONS_REQUEST_WRITE_SK = 102;//寫SD卡許可權 public static final int MY_PERMISSIONS_REQUEST_READ_SD_PHOTOALBUM= 103;//寫SD卡許可權 public static final int MY_PERMISSIONS_REQUEST_WRITE_SK_PHOTOALBUM = 104;//寫SD卡許可權 public static final int CAPTURE_IMAGE_REQUEST = 104;//拍照後的返回值 public static final int LOAD_IMAGE_REQUEST = 105;//相簿的返回值 public static final int CLIP_IMAGE_REQUEST = 106;//剪裁圖片的返回值 public static final String IMAGE_TYPE = "image/*"; public static File mOutFile;//圖片uri路徑 public static File mImageFile=null;//圖片file路徑 public static Integer mBuildVersion=android.os.Build.VERSION.SDK_INT;//當前SDK版本
