How to create a dynamic context menu in android?

问题

@Override  
    public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) {  

        super.onCreateContextMenu(menu, v, menuInfo);  
        menu.setHeaderTitle("Selection Options");  
        menu.add(0, v.getId(), 0, "Remove");  
    }  

I want my menu to say "Remove AAPL"

I would get the string AAPL from my array adapter, but I am not sure how I can access my array adapters index from this method.

Example if you are using listviews with custom object:

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);

    AdapterContextMenuInfo info = (AdapterContextMenuInfo) menuInfo;
    MyObject obj = (MyObject) myListView.getItemAtPosition(info.position);

    menu.setHeaderTitle("Selection Options");  
    menu.add(0, v.getId(), 0, "Remove " + obj.name); 
}

Cast menuInfo to an AdapterView.AdapterContextMenuInfo object. From there, you can get the position and id of the item in the ListView that was long-tapped.
