I cannot figure out how to get a context menu when using a class
derived from CursorAdapter in my ListActivity.
Using a SimpleCursorAdapter works fine ...
onCreate(Bundle b) {
...
SimpleCursorAdapter sca = new SimpleCursorAdapter(...);
setListAdapter(sca);
registerForContextMenu(getListView());
}
Overriding onCreateContextMenu(...) and onContextMenuItemSelected(...)
all work fine with the context menu behaving as expected (ie appearing
an functioning)
However, changing to use a class derived from CursorAdapter results in
no callbacks to either of the two above methods. I have noticed that
in this version the List View items don't get 'highlighted' when I
click on them - so there is probably some problem in linking the View
created in the CursorAdapter back to the register function
Here is the code
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.adapted_list);
mDbHelper = new MyDbAdapter(this);
mDbHelper.open();
Cursor cursor = mDbHelper.getAllEntries();
startManagingCursor(cursor);
setListAdapter(new CheckBoxAdapter(this, cursor));
registerForContextMenu(getListView());
}
CheckBoxAdapter derives from CursorAdapter and implements the newView
and bindView overrides. The objective being to have each list row as a
number of widgets (text, checkBox) etc. This part is working fine
including the callback to the checkBox. I've not shown
onCreateContextMenu(...) and onContextMenuItemSelected(...) as they
are not being called.
