How to get data in OnItemClickListener from SimpleCursorAdapter
I'm trying to set onItemClickListener for my adapter, and it works but now i don't know how to get clicked object ? I have a list with notes and on click I want to start new activity with id of clicked note.
private DatabaseHelper dbhelper;
SimpleCursorAdapter adapter = null;
public OnItemClickListener listener = new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "it works", Toast.LENGTH_SHORT).show();
}
};
@Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.first);
dbhelper = new DatabaseHelper(getApplicationContext());
Cursor cursor = dbhelper.getAllNotes();
startManagingCursor(cursor);
ListView lv = (ListView)findViewById(android.R.id.list);
String[] columns = new String[] {"NoteTitle", "NoteDate"};
int[] to = new int[] { R.id.title_entry, R.id.date_entry};
adapter = new SimpleCursorAdapter(this, R.layout.note_entry, cursor, columns, to);
lv.setAdapter(adapter);
lv.setOnItemClickListener(listener);

...
public Cursor getAllNotes()
{
SQLiteDatabase db=this.getReadableDatabase();
return db.query(noteTable, new String [] {colID, colTitle, colDesc, colDate}, null, null, null, null, null);
}
...
What should I insert into onItemClick to get note id(Toast is only for check if it works) ? I was looking for answer but I didn't find ;/
Thanks in advance

well last element argument is the id of the clicked row. you can use that row to get data
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(this, MyCustomDetailActivity.class);
intent.putExtra("item-identifier", id);
startActivity(intent);
}
