Rotate ImageView source from layout xml file

I have this ImageView in my layout:

<ImageView android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:contentDescription="@string/image_divider"
        android:paddingBottom="8dp"
        android:paddingTop="4dp"
        android:scaleType="fitXY"
        android:src="@android:drawable/divider_horizontal_textfield" />

It's a horizontal divider. I want to rotate it 90 degrees so I have a vertical divider.
Is there any possible way to do it right here from the layout and not the Activity class?

You can use Available Since API Level 11

android:rotation="90"

Final Code to Put,

<ImageView android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:rotation="90"
        android:contentDescription="@string/image_divider"
        android:paddingBottom="8dp"
        android:paddingTop="4dp"
        android:scaleType="fitXY"
        android:src="@android:drawable/divider_horizontal_textfield" />

Add "id" at ImageView (if not generate auto):

 android:id="@+id/imageView"

and use the "id" (kotlin example):

val imageView = findViewById<ImageView>(R.id.imageView)
imageView.setRotation(90f) // rotate 90 degree

You can do that in your code by creating a new bitmap object. Check this out : http://android-er.blogspot.fr/2010/07/rotate-bitmap-image-using-matrix.html And specifically this function

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);
