Rotate View Hierarchy 90 degrees

Question

I am working on a subclass of FrameLayout that is supposed to rotate all of its children by 90 degrees. I am doing this to overcome the landscape-only camera limitation pres

I had the same problem and managed to solve it. Instead of rotating each view or the layout by hand, I used a LayoutAnimationController.

First, place a file in /res/anim/ called rotation.xml

Then, in your Activity's onCreate, do

  @Override
  public void onCreate(Bundle icicle) {
  super.onCreate(icicle);

     setContentView(R.layout.myscreen);

     Animation rotateAnim = AnimationUtils.loadAnimation(this, R.anim.rotation);
     LayoutAnimationController animController = new LayoutAnimationController(rotateAnim, 0);
     FrameLayout layout = (FrameLayout)findViewById(R.id.MyScreen_ContentLayout);
     layout.setLayoutAnimation(animController);
 }

If you want to rotate elements that lie above your camera preview view (SurfaceHolder), simply place a FrameLayout above the SurfaceHolder, place all your elements in that FrameLayout and call the Layout "MyScreen_ContentLayout". Done.

Hope that helped someone out, took me quite a while to get everything together.
