Do you want to rotate it, in your XML... or programatically (i.e. onClick)? — EGHDK, Dec 04 '12 at 08:28

Since you don't need animation, from API 11 or above, you can use

android:rotation = "90"

to rotate in XML itself. If you want to do it in code, say after a button click, then you can use its java equalant too

 yourLayout  = (LinearLayout) findViewById(R.id.your_id);
 yourLayout.setRotation(90.0f);

But not before API 11. See documentation.

android:rotation

rotation of the view, in degrees.

Must be a floating point value, such as "1.2".

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol rotation.

yeah,I know this method in API level 11. But what about lower api level?

I think you can have to rotate the view yourselves. And I believe the lchorus and Pete's answer in this thread does work. For Pete's answer he is using animation, but you can set animation duration of 0 to do it without any visible animation. There is no other straight forward way as far as I know..
