camera intent auto rotate to 90 degree

Question

In my code below, I am trying to take photo using native camera and upload to server but when I take it as portrait and view it in gallery as landscape which means, its rota

Answer 1

Matrix matrix=new Matrix();
imageView.setScaleType(ScaleType.MATRIX);   //required
matrix.postRotate((float) angle, pivX, pivY);
imageView.setImageMatrix(matrix);



This method does not require creating a new bitmap each time.. Hope this works.

Answer 2

I also faced this kind of problem while showing the images in listview. But using the EXIF data I was able to get a work around to set the images in proper orientation.

This is were the bitmap object for display is prepared :

  Matrix matrix = new Matrix();
  matrix.postRotate(getImageOrientation(url));
  Bitmap rotatedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(),
  bitmap.getHeight(), matrix, true);

This is the method used, in the 2nd line of above code, to rotate the images orientation.

 public static int getImageOrientation(String imagePath){
     int rotate = 0;
     try {

         File imageFile = new File(imagePath);
         ExifInterface exif = new ExifInterface(
                 imageFile.getAbsolutePath());
         int orientation = exif.getAttributeInt(
                 ExifInterface.TAG_ORIENTATION,
                 ExifInterface.ORIENTATION_NORMAL);

         switch (orientation) {
         case ExifInterface.ORIENTATION_ROTATE_270:
             rotate = 270;
             break;
         case ExifInterface.ORIENTATION_ROTATE_180:
             rotate = 180;
             break;
         case ExifInterface.ORIENTATION_ROTATE_90:
             rotate = 90;
             break;
         }
     } catch (IOException e) {
         e.printStackTrace();
     }
    return rotate;
 }

This may not be the precise answer to your question, it worked for me and hope it will be useful for you.
