imageView中的照片方向与三星手机

Question

我在三星设备上的图像有问题 每次我拍一张照片的垂直形式，但是当它调用图像库时，教室 垂直 它用ExifInterface类我无法找到导致

我每次拍照我打电话给我的类PreviewImage这是我显示出图像 后来我有带我到指定的个人资料照片我有这个方法的按钮onActivityResult

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK) { 
     try { 
      ExifInterface exifInterface = new ExifInterface(photoFile.getAbsolutePath()); 
      int exif = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL); 
      switch (exif) { 
       case ExifInterface.ORIENTATION_ROTATE_90: 
        orientation = 90; 
        break; 
       case ExifInterface.ORIENTATION_ROTATE_180: 
        orientation = 180; 
        break; 
       case ExifInterface.ORIENTATION_ROTATE_270: 
        orientation = 270; 
        break; 
      } 
     } catch (Exception e) { 
      Log.d("tmessages", e.toString()); 
     } 
     Intent intent = new Intent(this, PhotoViewer.class); 
     intent.putExtra(EXTRA_PHOTO_PATH, photoFile.getAbsolutePath()); 
     intent.putExtra(EXTRA_PHOTO_ORIENTATION, orientation); 
     intent.putExtra(EXTRA_PHOTO_EDIT, false); 
     startActivityForResult(intent, 10); 

    } 

这是我PhotoViewer类

private void sendPicture() { 
     Intent returnIntent = new Intent(); 
     returnIntent.putExtra("photoDescription", photoDescription.getText().toString()); 
     returnIntent.putExtra("photoPath", localPath); 
     returnIntent.putExtra("orientation", orientation); 
     setResult(Activity.RESULT_OK, returnIntent); 
     finish(); 
    } 

一旦拍摄完成返回我的个人资料类从那里它被称为

else if (requestCode == 10 && resultCode == Activity.RESULT_OK) { 
     if (photoFile != null&&LoginController.getInstance().xmppConnection.isConnected()) { 
      byte[] photo = AndroidUtilities 
        .createProfileImage(photoFile.getAbsolutePath()); 
      ProfileManager.getInstance().publishPhoto(photo); 
      Bitmap decodedByte = BitmapFactory.decodeByteArray(photo, 0, photo.length); 
      avatar.setImageBitmap(decodedByte); 
     }else{ 
      Toast.makeText(this,R.string.LabelProfilePhotoFailed, Toast.LENGTH_SHORT).show(); 
     } 
    } 

的onActivityResult方法我怎样才能使形象展示我垂直在个人资料照片？

你已经完成了一半的工作！只需使用您之前计算的方向：

else if (requestCode == 10 && resultCode == Activity.RESULT_OK) { 
    if (photoFile != null&&LoginController.getInstance().xmppConnection.isConnected()) { 
     byte[] photo = AndroidUtilities 
       .createProfileImage(photoFile.getAbsolutePath()); 
     ProfileManager.getInstance().publishPhoto(photo); 
     Bitmap decodedByte = BitmapFactory.decodeByteArray(photo, 0, photo.length); 
->  decodedByte = rotate(decodedByte, orientation); 
     avatar.setImageBitmap(decodedByte); 
    }else{ 
     Toast.makeText(this,R.string.LabelProfilePhotoFailed, Toast.LENGTH_SHORT).show(); 
    } 
} 

当方向 = getIntent（）getExtras（）getInt（EXTRA_PHOTO_ORIENTATION）。

private static Bitmap rotate(Bitmap bm, int rotation) { 
    if (rotation != 0) { 
     Matrix matrix = new Matrix(); 
     matrix.postRotate(rotation); 
     Bitmap bmOut = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true); 
     return bmOut; 
    } 
    return bm; 
}
