Detect orientation change while requested orientation is set

Question

Is it possible to get a event when the screen orientation changes while

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

is set?

The purpose of this is, once a user opens a video in full screen mode, then the screen will go landscape.

When the user goes (back) to portrait, the video minimizes.

This method of activity will called.

 @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); // Checks the orientation of the screen if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) { Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show(); } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){ Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show(); } }

Hmm, I doesn't get called anymore once I set the orientation.

I am also interested to get ALL 4 orientations and Did not find a suitable solution yet. I started implementing Sensors. But this includes all orientations of the device. Would like to know, how I only can receive 0,90,180,270.

@icbytes, look at this question stackoverflow.com/questions/3611457/…

Please share your code. I think you are using it in oncreate method.

Well, I don't know if you tried it yourself but once you set the requested orientation (to landscape or portrait), the onConfigurationChanged will no longer be called. Thanks

Try this:

private OrientationEventListener mOrientationEventListener; private int mOrientation = -1; private static final int ORIENTATION_PORTRAIT_NORMAL = 1; private static final int ORIENTATION_PORTRAIT_INVERTED = 2; private static final int ORIENTATION_LANDSCAPE_NORMAL = 3; private static final int ORIENTATION_LANDSCAPE_INVERTED = 4; @Override protected void onResume() { super.onResume(); if (mOrientationEventListener == null) { mOrientationEventListener = new OrientationEventListener(this, SensorManager.SENSOR_DELAY_NORMAL) { @Override public void onOrientationChanged(int orientation) { // determine our orientation based on sensor response int lastOrientation = mOrientation; if (orientation >= 315 || orientation < 45) { if (mOrientation != ORIENTATION_PORTRAIT_NORMAL) { mOrientation = ORIENTATION_PORTRAIT_NORMAL; } } else if (orientation < 315 && orientation >= 225) { if (mOrientation != ORIENTATION_LANDSCAPE_NORMAL) { mOrientation = ORIENTATION_LANDSCAPE_NORMAL; } } else if (orientation < 225 && orientation >= 135) { if (mOrientation != ORIENTATION_PORTRAIT_INVERTED) { mOrientation = ORIENTATION_PORTRAIT_INVERTED; } } else { // orientation <135 && orientation > 45 if (mOrientation != ORIENTATION_LANDSCAPE_INVERTED) { mOrientation = ORIENTATION_LANDSCAPE_INVERTED; } } if (lastOrientation != mOrientation) { // changeRotation(mOrientation, lastOrientation); } } }; } if (mOrientationEventListener.canDetectOrientation()) { mOrientationEventListener.enable(); } } public void onOrientationChanged(int orientation) { // determine our orientation based on sensor response int lastOrientation = mOrientation; Display display = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay(); if (display.getOrientation() == Surface.ROTATION_0) { // landscape oriented devices if (orientation >= 315 || orientation < 45) { if (mOrientation != ORIENTATION_LANDSCAPE_NORMAL) { mOrientation = ORIENTATION_LANDSCAPE_NORMAL; } } else if (orientation < 315 && orientation >= 225) { if (mOrientation != ORIENTATION_PORTRAIT_INVERTED) { mOrientation = ORIENTATION_PORTRAIT_INVERTED; } } else if (orientation < 225 && orientation >= 135) { if (mOrientation != ORIENTATION_LANDSCAPE_INVERTED) { mOrientation = ORIENTATION_LANDSCAPE_INVERTED; } } else if (orientation <135 && orientation > 45) { if (mOrientation != ORIENTATION_PORTRAIT_NORMAL) { mOrientation = ORIENTATION_PORTRAIT_NORMAL; } } } else { // portrait oriented devices if (orientation >= 315 || orientation < 45) { if (mOrientation != ORIENTATION_PORTRAIT_NORMAL) { mOrientation = ORIENTATION_PORTRAIT_NORMAL; } } else if (orientation < 315 && orientation >= 225) { if (mOrientation != ORIENTATION_LANDSCAPE_NORMAL) { mOrientation = ORIENTATION_LANDSCAPE_NORMAL; } } else if (orientation < 225 && orientation >= 135) { if (mOrientation != ORIENTATION_PORTRAIT_INVERTED) { mOrientation = ORIENTATION_PORTRAIT_INVERTED; } } else if (orientation <135 && orientation > 45) { if (mOrientation != ORIENTATION_LANDSCAPE_INVERTED) { mOrientation = ORIENTATION_LANDSCAPE_INVERTED; } } } if (lastOrientation != mOrientation) { // changeRotation(mOrientation, lastOrientation); } } } } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); }
