Resizing fragment after setRotation

Looked around for an answer to this but can only find others with the same problem and no resolution. I am trying to rotate a regular SherlockFragment inflated with a very simple layout (just for test purposes):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/jan"
    android:textColor="@color/standard_text_color"
    android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>

The fragment code:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{   
    View result = inflater.inflate(R.layout.foo_layout, null);
    result.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,  ViewGroup.LayoutParams.MATCH_PARENT));
    result.setRotation(90); 
    return result;
}

This will rotate the view about the pivot in the middle but will not change the layout to the correct bounds. The best that I have managed to do is to setPivotX(size.x/2) and setPivotY(size.x/2) with size.x being the screen width of the device and setLayoutParams(size.y, size.y). This kind of works in that it creates a square the size of the fragment but runs off the width due to it being set to size.y not x however setLayoutParams(size.x, size.y) just creates half a square...and bizarrely so does setLayoutParams(size.y, size.x).

Does anyone have any resolution to this where the fragment will resize to the correct x and y co-ordinates to fill the screen after the whole fragment is rotated?

In the FrameLayout holder in the activity xml I set:

android:clipChildren="false"

I then used translationX and translationY on the rotated view to move it into position and viola it worked. I would say this in essence is a bug in Android, after rotation, the clipping bounds for width and height remain the same but should be swapped.
