void WindowOrientationObserver::Notify(
    const mozilla::hal::ScreenConfiguration& aConfiguration) {
  uint16_t currentAngle = aConfiguration.angle();
  if (mAngle != currentAngle && mWindow->IsCurrentInnerWindow()) {

示例#3

文件： gfxVRCardboard.cpp 项目： bolt-dev/gecko-dev

// Android sends us events that have a 90-degree rotation about 
// the x axis compared to what we want (phone flat vs. phone held in front of the eyes).
// Correct for this by applying a transform to undo this rotation.

  mOrient = config.orientation();
