Android layout configChanges

Question

I created layout and layout-land folders, in Manifest i have

android:configChanges="keyboardHidden|orientation"

If i remove the android:configChanges from the Manifest I can see the layout change from portrait to landscape...the problem is that the previous screens are destroyed when trying to go back.

I am assuming i could add some code in my Java to tell it when to change layouts. I have read a bunch of posts already but am confused where in the code it would happen.

I am trying to use some prepackaged code because I am new to Android. The link below is the Java code for the menu screen in particular i need to change layouts for. thanks so much!!

how did you start the previous activities (which I assume are the screens you refer) — Julian Suarez, Apr 05 '12 at 09:29

Adding android:configChanges="keyboardHidden|orientation" will stop re-creation of your Activity and also prevent from changing the layout to layout-land/portrait layout. In that case you have to manage it manually from the java code. If you don't want your Activity to get re-created when you rotate your device/ change orientation. What you can do is just change the layout when your screen orientation changes inside onConfigurationChanged() method,

Check my answer here, how can that be done.

Thanks for responding. I believe this is what I want."What you can do is just change the layout when your screen orientation changes inside onConfigurationChanged() method," Still confused where it fits in my code? – user1120680 Apr 05 '12 at 09:50

My work around for these problem was

in manifeast file you can use android:configChanges="keyboardHidden|orientation" if you wont these line then activity will be destroyed and created again.

and we have a below method

@Override
public void onConfigurationChanged(Configuration newConfig) {
    // TODO Auto-generated method stub
    super.onConfigurationChanged(newConfig);
    setContentView(R.layout.yourlayoutname);
}

here you can handle the orientation change...
