How to resolve this orientation problem in Android?

In my project I am taking one textview and one button and when I am clicking on button I am displaying some text in the textview which I am getting from an arraylist.

When I change the orienta开发者_StackOverflowtion to landscape I am using onSavedInstanceState(...) and onRestoreInstanceState(..) and getting the text displayed on textview and in landscape mode I am removing the text on textview and I am changing the orientation to portrait but I am getting the text on textview.

How can I resolve this?

TextView saves its state by itself. If you don't want TextView to save its state, add android:saveEnabled="false" attribute or call TextView.setSaveEnabled(false).

On orientation changes, activity restarts. When an orientation change occurs Android calls a special method called onRetainNonConfigurationInstance. You can use this method to save an object, and afterwards you can get that object by using getLastNonConfigurationInstance method. You can see an example here
