질문1. 아래처럼 했는데 가끔 더보기진행될때 죽어요

java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. [in ListView(16908298, class android.widget.ListView) with Adapter(class android.widget.HeaderViewListAdapter)]
