Ok - and where are you setting setContentView(...)? The lv

ListView lv = (ListView) findViewById(R.id.list);

is null because you didn't set contentView.

Probably the reason for this is: you're setting OnClickListener to null in AlertDialog.Builder in setNeutralButton("OK", null).

So when you click "OK" Android invokes (internally) something like this:

neutralButtonListener.onClick(...);

And the neutralButtonListener is null. So you should just provide empty listener at least.
