[android-developers] Text dissapears when view is rotated in getChildStaticTransformation (4.x / maybe also honeycomb)

I'm rotating a custom view, which contains a textview, using getChildStaticTransformation:

@Override
protected boolean getChildStaticTransformation(View child, Transformation t) {
  t.clear();
  t.setTransformationType(Transformation.TYPE_MATRIX);
  camera.save();
  final Matrix imageMatrix = t.getMatrix();

  float transX = (textView.getWidth() / 2.0f);
  float transY = (textView.getHeight() / 2.0f);

  camera.rotateY(rot);
  camera.getMatrix(imageMatrix);
  imageMatrix.preTranslate(-transX, -transY);
  imageMatrix.postTranslate(transX, transY);
  camera.restore();
  //...
}

This works very well on all 2.x devices I have tested, but in 4.x devices, on angle != 0, the text dissapears. Rotation works well, but the text dissapears. It appears again if rotation is 0.

What can I do to solve this? Thanks in advance!
