Android - ImageView showing image from Gallery in “landscape”

Question

First at all, maybe "landscape" isn't the better word to describe, but i can't think another one in the moment.

I'm using the following code to show an image in an ImageView, but my image that was taken with the device in "portrait" (head up) is showing sidelong.

My code:

mImageView  = (ImageView) findViewById(R.id.iv_photo);

Uri u = Uri.parse("content://media/external/images/media/7");
mImageView.setImageURI(u);

XML:

<ImageView
    android:id="@+id/iv_photo"
    android:layout_width="wrap_content"          
    android:layout_height="wrap_content"/>

And yes, "content://media/external/images/media/7" is a valid path.

Any ideas?

Answer 1

Just check the image's dimensions, if it's taller than it is wider, then you can rotate it:

The relevant bits are:

  bitmap = BitmapFactory.decodeFile(imageInSD);
  bmpWidth = bitmap.getWidth();
  bmpHeight = bitmap.getHeight();

  Matrix matrix = new Matrix();
  matrix.postScale(curScale, curScale);
  matrix.postRotate(curRotate);

  Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bmpWidth, bmpHeight, matrix, true);
  myImageView.setImageBitmap(resizedBitmap);

Answer 2

android:id="@+id/iv_photo"

android:layout_width="320dip"   

android:layout_height="wrap_content"/>

Use this it may works
