[android-beginners] Re: how to get the string from a listview item
You could also do something like this in your onListItemClick.
SQLiteCursor cursor = (SQLiteCursor) l.getItemAtPosition
(position);
String title = cursor.getString(cursor.getColumnIndexOrThrow
(RingtoneManager.EXTRA_RINGTONE_TITLE));

Try something like this in your onListItemClick.
TextView textView = (TextView) v.findViewById(R.id.title);
String text = textView.getText().toString();

[android-beginners] Re: Adding submenus in XML
In a menu XML layout, there are three valid elements: ,
and . The item and group elements must be children of a menu,
but item elements may also be the children of a group, and another
menu element may be the child of an item (to create a Submenu). Of
course, the root node of any file must be a menu element.

[android-beginners] Re: Setting Single Choice Dialog Checked Item
I set a breakpoint in onPrepareDialog and looked at the dialog object.
It contained a field called mAlert which contained a listview called
mListVIew
and that listview had a field called mId which had a value of
16908667.
I then tried using that value in the findViewById method. It didn't
work
though until I cast the dialog as an AlertDialog.

[android-beginners] Re: Setting Single Choice Dialog Checked Item
Every view in Android has an id number assigned to it.
When you put android.R.id.button1 for example that is a constant that
defines the number 16908313.
The number 16908667 does not seem to have a constant defined for it in
the SDK.
This means that this number could be possibly be changed in a future
version of the SDK
and would break your program. I don't know why they have decided not
to include that number.
You can see the defined constants at this link.

[android-beginners] Re: Setting Single Choice Dialog Checked Item
I also had to do one of the following to get it to work correctly.
if (!lv.isItemChecked(0)) {
lv.setItemChecked(0, true);
}
or
lv.clearChoices();
lv.setItemChecked(0, true);

This seems to work for me. I have not been able to find a constant in
