当设备不旋转/移动时，OrientationEventlistener将不工作。
我发现display listener是检测变化的更好方法。

DisplayManager.DisplayListener mDisplayListener = new DisplayManager.DisplayListener() {
        @Override
        public void onDisplayAdded(int displayId) {
           android.util.Log.i(TAG, "Display #" + displayId + " added.");
        }

        @Override
        public void onDisplayChanged(int displayId) {
           android.util.Log.i(TAG, "Display #" + displayId + " changed.");
        }

        @Override
        public void onDisplayRemoved(int displayId) {
           android.util.Log.i(TAG, "Display #" + displayId + " removed.");
        }
     };
     DisplayManager displayManager = (DisplayManager) mContext.getSystemService(Context.DISPLAY_SERVICE);
     displayManager.registerDisplayListener(mDisplayListener, UIThreadHandler);

您可能应该在OrientationEventListener中添加一些逻辑代码，如下所示：

mWindowManager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);

OrientationEventListener orientationEventListener = new OrientationEventListener(this,
        SensorManager.SENSOR_DELAY_NORMAL) {
    @Override
    public void onOrientationChanged(int orientation) {

        Display display = mWindowManager.getDefaultDisplay();
        int rotation = display.getRotation();
        if ((rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270) && rotation != mLastRotation) {
            Log.i(TAG, "changed >>> " + rotation);

            // do something

            mLastRotation = rotation;
        }
    }
};

if (orientationEventListener.canDetectOrientation()) {
    orientationEventListener.enable();
}

我用这个代码让它为我的案子工作。

OrientationEventListener mOrientationEventListener = new OrientationEventListener(mActivity)
  {
     @Override
     public void onOrientationChanged(int orientation)
     {
        if (orientation == ORIENTATION_UNKNOWN) return;

        int rotation = mActivity.getWindowManager().getDefaultDisplay().getRotation();
        switch (rotation) {
          case Surface.ROTATION_0:
             android.util.Log.i(TAG, "changed ROTATION_0 - " + orientation);
             break;
          case Surface.ROTATION_90:
             android.util.Log.i(TAG, "changed ROTATION_90 - " + orientation);
             break;
          case Surface.ROTATION_180:
             android.util.Log.i(TAG, "changed ROTATION_180 - " + orientation);
             break;
          case Surface.ROTATION_270:
             android.util.Log.i(TAG, "changed ROTATION_270 - " + orientation);
             break;
        }
        if ((rotation != mLastRotation) && (rotation & 0x1) == (mLastRotation & 0x1))
        {
           android.util.Log.i(TAG, "unhandled orientation changed >>> " + rotation);
        }
        mLastRotation = rotation;
     }
  };

  if (mOrientationEventListener.canDetectOrientation()){
     mOrientationEventListener.enable();
  }

您仍然需要使用显示侦听器类：Google推荐使用它来处理从解锁方向开始的180度设备旋转。您不能简单地将对onDisplayChanged的所有回调都视为180度旋转。Google的一个更完整的实现展示了如何在superuser提到的onDisplayChanged回调期间从显示管理器收集显示旋转。

/** DisplayManager to listen to display changes */
private val displayManager: DisplayManager by lazy {
    applicationContext.getSystemService(DISPLAY_SERVICE) as DisplayManager
}

/** Keeps track of display rotations */
private var displayRotation = 0

...

override fun onAttachedToWindow() {
    super.onAttachedToWindow()
    displayManager.registerDisplayListener(displayListener, mainLooperHandler)
}

override fun onDetachedFromWindow() {
    super.onDetachedFromWindow()
    displayManager.unregisterDisplayListener(displayListener)
}

private val displayListener = object : DisplayManager.DisplayListener {
    override fun onDisplayAdded(displayId: Int) {}
    override fun onDisplayRemoved(displayId: Int) {}
    override fun onDisplayChanged(displayId: Int) {
        val difference = displayManager.getDisplay(displayId).rotation - displayRotation
        displayRotation = displayManager.getDisplay(displayId).rotation

        if (difference == 2 || difference == -2) {
            createCaptureSession()
        }
    }
}
