Android Endless Listview的屏幕旋转

Question

I'm trying the CommonsWare's android endlist adapter.

After loading a couple of pages, i rotated the screen, and the listview loses all the pages except the first one. Doesn't it supposed to retain the loaded items?

That is your job, not the adapter's. Adapters do not "retain" "items", regardless of whether EndlessAdapter is involved or not.

By default, activities are destroyed and recreated when the device undergoes a configuration change, such as a screen rotation. You need to arrange to hang onto your model data when this occurs, by:

• using setRetainInstance() on a dynamic fragment, or
• using onSaveInstanceState() , or
• using onRetainNonConfigurationInstance() , or
• in the worst case, using android:configChanges , as suggested in another answer
