Hi:
I want to use this listener to catch the screen orientation change.
But I don't know how to use it, I tried new it and add my codes in its
method onOrientationChanged, the codes looks like:
myOrientationListener = new OrientationEventListener(this) {
public void onOrientationChanged(int orientation) {
System.out.println("**********onOrientationChanged");
if (null == mWebViewState)
// save some state for current view so that restore them for
new screen orientation
.....
}
};
myOrientationListener.enable();
I put these codes in onCreate() function, no exception raised when
application run, but the screen is black, nothing could be showed in
my web browse view. I looked the ddms output:
06-02 18:12:19.708: INFO/System.out(7216): *****onCreate()
06-02 18:12:19.708: INFO/System.out(7216): ********onStart()

Seems the listener register is failed. I don't know why and also don't
know how to use it, is it need to register on SensorManager? But I did
not find any about register function for it in SensorManager.
Could you help me? Thanks a lot!
My intent of using it is that I want to keep the same web page and
same browsing position in this listener only after screen orientation
is changed. If you have another idea for my purpose without using
OrientationEventListener, please tell me and thank you very much!
