SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
R.layout.list_item,
c,
new String[]{MyDBHelper.KEY_NAME, MyDBHelper.KEY_ID},
new int[]{R.id.field_name});
i.e. leave the KEY_ID at the end of the String[] and do not link it to any
View.
Create the context menu and get the KEY_ID
registerForContextMenu(list);
list.setOnCreateContextMenuListener(new
OnCreateContextMenuListener()
{
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo)
{
menu.add(0, 1, 0, R.string.menu_item_delete_user);
}
});
list.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> adapterView, View v, int
arg2, long arg3)
{
Cursor cursor = (Cursor)
adapterView.getItemAtPosition(arg2);
int key_id =
cursor.getInt(cursor.getColumnIndex(MyDBHelper.KEY_ID));
...
}
});
}
