Android: How to find the position clicked from the context menu

Question

I have a list view filled with data. I set up a context menu for the listview using the following code:

list.setOnCreateContextMenuListener
(
  new View.OnCr         


        

Answer 1

You can use the ContextMenu.ContextMenuInfo.

Something like that:

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
    int index = info.position;
}

You can also get the exact View for which the menu is being displayed:

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
    int index = info.position;
    View view = info.targetView;
}

Answer 2

OK, to solve problem info null **** use static member and set value from Position of your holder to save the value in longclick method member for example:-

public class CurrentPosition {
   public static  int Pos{ get; set; }
}

public bool OnLongClick(View v)
{
    CurrentPosition.Pos = Position;
    return false;
}

and use in your context select item:

public override bool OnContextItemSelected(IMenuItem item)
{
    switch (item.ItemId)
    {
        case 0:
            return true;
        case 1:
            Toast.MakeText(this,CurrentPosition.Pos.ToString(), ToastLength.Long).Show();
            return true;
        case 2:
            Toast.MakeText(this, "Save", ToastLength.Long).Show();
            return true;
        }
        return true;
    }
}

Answer 3

private static final int EDIT_ID = Menu.FIRST + 3;
private static final int DELETE_ID = Menu.FIRST + 4;
 @Override
    public void onCreateContextMenu(ContextMenu menu, View v,
            ContextMenu.ContextMenuInfo menuInfo) {
        menu.add(Menu.NONE, EDIT_ID, Menu.NONE, "Edit").setAlphabeticShortcut(
                'e');
        menu.add(Menu.NONE, DELETE_ID, Menu.NONE, "Delete")
                .setAlphabeticShortcut('d');
    }

    @Override
    public boolean onContextItemSelected(MenuItem item) {
        AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item
                .getMenuInfo();
        switch (item.getItemId()) {
        case EDIT_ID:

            edit(info.id);
            return (true);
        case DELETE_ID:

            delete(info.id);
            return (true);
        }

        return (super.onOptionsItemSelected(item));
    }
