I have a SearchActivity that I build in accordance to http://developer.android.com/guide/topics/search/search-dialog.html. After getting my data from a local content provider, I am using a basic CursorAdapter to display it in a ListView. So far everything works fine. Then in the listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {}); I setup to return a result to the calling activity and then call finish().
But what is happening is that finish() keeps clearing the adapter instead of finishing the Activity. I try different flavors of finish and onBackPressed but no difference: it clears the ListView but remains in the activity. Can anyone see what I am doing wrong?
