android: How to cancel orientation change

Question

I want to cancel auto rotation of views in my app. There are a lot of posts targeting this topic[1], all of them suggesting things like setting

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

or

 <activity android:name=".myActivity"                  
          android:screenOrientation="portrait">

which does exactly what I need, but prevents onConfigurationChanged() from firing, meaning that I am not able to track the orientation of the phone any longer. The thing is: I need to know about the orientation at some point.

Any ideas how I could get the orientation of the phone without enabling rotation of views?

Might I suggest using the OrientationEventListener? I think you will still get the notifications even if you set the orientation in your manifest.xml file.

If you need to obtain the rotation use Display#getRotation().

the weird thing is (very uncool!!): this only works if you don't fix the screen orientation (e.g. with setRequestedOrientation) – stoefln Jan 06 '12 at 16:21

If you need this information for rotating the screen, you should implement the onConfigurationChanged yourself.

If you need this information for any other purpose, I think you should use the sensors (accelerometer or compass)

I already overwrote onConfigurationChanged, but still my views are rotated, and I don't know how to intercept this orientation change. I need the orientation for saving the images with the right orientation (I'm writing a camera app) – stoefln Jan 06 '12 at 16:20

As you say "The thing is: I need to know about the orientation at some point."

You can check orientation any time

int orientation = getWindow().getWindowManager().getDefaultDisplay().getOrientation();
    if(orientation == 0){ //horizontal

    }else if(orientation == 1){ //vertical

    }

This only works without setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); – stoefln Jan 06 '12 at 16:29
