阅读更多关于 Android ImageButton in ListView row clicklistener not responding

问题 I have a ListView with rows that contain ImageButtons (shown as 'O' below): [<-------TextView-------> O O O] [<-------TextView-------> O O O] I am finding that the first row has intermittent behaviour. At first it appeared that the image button onclicklisteners were not being called for just the top row. What I have found is that the onclicklisteners for the buttons do get called, but the clicks seem to be queued/buffered until I click on the row itself. I will happily post some code if

问题 I have strange behavoir in a ViewBinder. All works good on TextViews.

问题 I'm trying to display a list of contacts that are currently stored in a SQLiteDatabase .

问题 I've populated a ListActivity from a Cursor using SimpleCursorAdapter that starts another activity when one of the list items have been clicked. I'm also using ViewBinder to do some custom transformation of the data. I want to add a CheckBox to each row in the list so I've changed the view and added a CheckBox with gravity right. Adding the CheckBox has removed the ability to click on the items. The onListItemClick method I was overriding in ListActivity is no longer called when you press on

So I've got a ListView (using a ListActivity ) that I'm populating from a SQLiteDatabase . I'm trying to attach the ID (PK) of the row to the view, so that onListItemClick of each list item, I can do stuff with that ID.

Here's a pared down version of what I'm using (for simplicity/brevity): public class Favorites extends ListActivity { public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState);
