copied!<p>Instead of using something global like <em>android:configChanges</em> which affect ALL the views in the Activity, what about using the method <strong>setSaveEnabled(boolean)</strong> or the equivalent xml attribute <strong>android:saveEnabled</strong> ?</p> <blockquote> <p>Controls whether the saving of this view's state is enabled (that is, whether its onSaveInstanceState() method will be called).</p> </blockquote> <p>If you set it to false it should always go back to the default state when changing orientation because its state won't be saved.</p> <p>You could, for example, put this in the layout file:</p> <pre><code><ListView .... android:visibility="invisible" android:saveEnabled="false"> </ListView> </code></pre> <p>and then set the visibility to VISIBLE when you start typing. Or if you prefer put the visibility and the method <em>setSaveEnabled</em> in the onCreate method.</p> <p>I tried with a simple ListView and a Button that changes the visibility to true. On rotation the ListView became invisibile(its default state)</p> <p>Also note that:</p> <blockquote> <p>This flag can only disable the saving of this view; any child views may still have their state saved.</p> </blockquote> <p>so you should have to clear the list during onStop() or whatever method you want but if even if you don't, the ListView will still be invisible on rotation</p> <p>Source:</p> <ul> <li><a href="http://developer.android.com/reference/android/view/View.html#attr_android:saveEnabled" rel="noreferrer">http://developer.android.com/reference/android/view/View.html#attr_android:saveEnabled</a></li> <li><a href="http://developer.android.com/reference/android/view/View.html#setSaveEnabled%28boolean%29" rel="noreferrer">http://developer.android.com/reference/android/view/View.html#setSaveEnabled%28boolean%29</a></li> </ul>
