May be you should add some logical code in your OrientationEventListener like this:

<pre><code>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) &amp;&amp; rotation != mLastRotation) {
 Log.i(TAG, "changed &gt;&gt;&gt; " + rotation);

 // do something

 mLastRotation = rotation;
 }
 }
};

if (orientationEventListener.canDetectOrientation()) {
 orientationEventListener.enable();
}
</code></pre>

I use this code to have it work for my case.

<pre><code> 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) &amp;&amp; (rotation &amp; 0x1) == (mLastRotation &amp; 0x1))
 {
 android.util.Log.i(TAG, "unhandled orientation changed &gt;&gt;&gt; " + rotation);
 }
 mLastRotation = rotation;
 }
 };

 if (mOrientationEventListener.canDetectOrientation()){
 mOrientationEventListener.enable();
 }
</code></pre>

OrientationEventlistener won't work when the device isn't rotating/moving.

I find display listener is a better way to detect the change.

<pre><code> 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);
</code></pre>

I've seen a few other questions similar to this but no answers.

Rotating from portrait to landscape (either direction) and back again, we get the helpful call to onConfigurationChanged().

However, when rotating from landscape to landscape (through 180 degrees) onConfigurationChanged() is not called.

I've seen mention of using OrientationEventListener but this seems flakey to me because you can rotate quickly around without triggering a display orientation change.

I've tried adding a layout change listener, but with no success.

So the question is, how to reliably detect such a change in landscape orientation?

How to detect screen rotation through 180 degrees from landscape to landscape orientation?

我还看过其他一些类似的问题，但没有答案。从纵向旋转到横向(任意方向)再旋转回来，我们得到了对onConfigurationChanged()的有用调用。但是，当从一个景观旋转到另一个景观( 180度)时，不会调用onConfigurationChanged()。我曾经提到过使用OrientationEventListe...
