Question

I’m making a base class for my androids screen, it is has a list control. Is there a way for when the base class’s onListItemClick gets called, saying a list item was selected. It could call a function in the parent class??

Code:

public class cHome extends cBase {
String[] MyItems={ 
        "Gate Directions",
        "Food & Beverges",
        "Shjops",
        "Banking",
        "Official Agencies",
        "Amenities & Services",
        "Restrooms"
        };

public void onCreate(Bundle icicle) {
    super.onCreate(icicle, MyItems);
//  Display=MyItems;
}

Code:

public class cBase extends ListActivity  {

String[] items={"CASUAL","DRESSES","CAREER","OUTWEAR","FOOTWEAR",
        "JEWELRY","ACCESSORIES"};
String[] Display;


public void onCreate(Bundle icicle, String[] items2) {
     Display=items2;
    super.onCreate(icicle);

    setContentView(R.layout.baselayout);
    setListAdapter(new IconicAdapter(this));
//  selection=(TextView)findViewById(R.id.selection);

// set values in header
     // set header
     TextView mFlight = (TextView)findViewById(R.id.idFlyerFlightNumber);
     mFlight.setText( cGlobals.mFlightNumber);     

     TextView mDes = (TextView)findViewById(R.id.idFlyerDestanation);
     mDes.setText( cGlobals.mDestanation);

}


class IconicAdapter extends ArrayAdapter {
    Activity context;

    IconicAdapter(Activity context) {
        super(context, R.layout.row, Display);

        this.context=context;
    }

    public View getView(int position, View convertView,
                                            ViewGroup parent) {
        LayoutInflater inflater=context.getLayoutInflater();
        View row=inflater.inflate(R.layout.row, null);
        TextView label=(TextView)row.findViewById(R.id.label);

        label.setText(Display[position]);
        ImageView icon=(ImageView)row.findViewById(R.id.icon);

//      String[] items={"CASUAL","DR ESSES","CAREER","OUTWEAR","FOOTWEAR",
    //          "JEWELRY","ACCESSORIES"};

        switch(position)
        {
        case 0:
    //      icon.setImageResource(R.drawable.formobile_items);
            break;

        case 1:
        //  icon.setImageResource(R.drawable.fashion_dress);
            break;

        case 2:
//          icon.setImageResource(R.drawable.fashion_career);
            break;

        case 3:
//          icon.setImageResource(R.drawable.fashion_outwear);
            break;

        case 4:
    //      icon.setImageResource(R.drawable.fashion_footwear);
            break;

        case 5:
//          icon.setImageResource(R.drawable.fashion_jewelry);
            break;

        case 6:
//          icon.setImageResource(R.drawable.fashion_accessories);
            break;


        }
        return(row);
    }
}
}

Answer 1

You can override onListItemClick in your child class and just call super.onListItemClick on it. Or don’t override it and onListItemClick method of base class will be called automatically when item in the list selected.
