Question

In the application I am writing, I have a main class which extends the ListActivity – it contains a list of elements. I want these elements to link to a different page (an xml one, or perhaps a View object). However, I realised one cannot use the method setContentView(int) on a ListActivity object.

What’s to be done?

Thanks!

Looks like you are trying to launch a new activity.

You have to override the onListItemClick method of ListActivity.

Here is the code.

// ListView l points to list view whose item user clicked
// View v points to the item in the list view on which the user clicked
// int position is the position index of the item in the list
// long id is the id assigned to the item. This id is assigned using the ListAdapter, CursorAdapter etc.
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);

    // I am using getApplicationContext() as it is more safe then just passing `this`
    Intent i = new Intent(this.getApplicationContext(), ActivityToRun.class);

    this.startActivity(i);
}

NOTE: You have to improve on this skeleton depending upon your needs.
