Question

In my app, in the OnCreate method, I create a list(using an add button) or I fetch it from a saved file. My function works fine and I am able to create and fetch the list until I rotate the phone(vertical -> horizontal). The list then disappears. I am still able to click the buttons on screen, but it seems I have no items in the list.Any help appreciated. Thank You in advance.

Answer 1

add this tag in Activity tag in manifest

android:configChanges="keyboardHidden|orientation"

and add this in activity code

@Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);


    }

in the same activity..

this happens because each time your screen orientation is changed onCreate() method of the Activity will be called every time
