Question

I am working on an android app, and I am having difficulties with ListActivity. I would like to have a different Activity start depending on which item in the list is clicked.

I made a list and referenced it with setListAdapter in java, but I am not sure how to reference in the OnListItemClick. I assume I need to reference the position in the list.

With Activity and Buttons, I can set the OnClickListener and use a switch statement with a case for each Button. What is the equivalent for ListActivity?

Here is my code:

public class Options extends ListActivity implements {

    String myHistory[]= { "Item 1", "Item 2", "Item 3" };

    //---Set ListView---
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setListAdapter(new ArrayAdapter<String> ( Options.this,
                                   android.R.layout.simple_list_item_1, myHistory)));
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub
        super.onListItemClick(l, v, position, id); 

        //--if click position 1, do below
        //--Intent a = new Intent("show Item 1's corresponding page");
        //--startActivity(a);

        //--if click item in position 2, do below
        //--Intent b = new Intent("show Item 2's corresponding page");
        //--startActivity(b);

        //--if click item in position 3, do below
        //--Intent c = new Intent("show Item 3's corresponding page");
        //--startActivity(c);
    }
}

as looks there are only few and certain data in list not at run time because each item has a separate activity (like a menu list of game) so I will suggest to go short and simple …….

    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub
        super.onListItemClick(l, v, position, id); 

        Intent a;
         switch(position){

        case 1:
            a = new Intent("show Item 1's corresponding page");
            break;
         case 2:
           a  = new Intent("show Item 2's corresponding page");
           break;
        case 3:
           a = new Intent("show Item 3's corresponding page");
           break;

        if(null!=a)
        startActivity(a);
     }
}
