        String[] listItems = {"Colour", "Font Size",};
        if(listItems[position].equals("Font Size"))
        {

Call this method in your onItemClick method :

 public void showMyCustomDialog(Context context, String title, String message)
    {
        final Dialog dialog = new Dialog(context);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        //tell the Dialog to use the customalertdialog.xml as it's layout description
        dialog.setContentView(R.layout.customalertdialog);
        TextView titleText = (TextView) dialog.findViewById(R.id.txtTitleAlertDialog);
        titleText.setText(title);
        TextView txt = (TextView) dialog.findViewById(R.id.txtAlertDialog);
        txt.setText(message);
        Button dialogButton = (Button) dialog.findViewById(R.id.buttonAlertDialogCancel);
        dialogButton.setText("OK");
        dialogButton.setOnClickListener(new View.OnClickListener() 
        {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        dialog.show();
    }

Something like below :

lv.setOnItemClickListener(new OnItemClickListener()
    {
        public void onItemClick(AdapterView<?> parent, View
                view, int position, long id)
        {
            String[] listItems = {"Colour", "Font Size",};
            if(listItems[position].equals("Font Size"))
            {
                    public dialog onCreateDialog(Bundle savedInstanceState)
                    {
                        showMyCustomDialog(Context context, String title, String message) // pass title, message and activity context in this method.
                    }
            }
        }
    });

Hope it will help.

move

 public dialog onCreateDialog(Bundle savedInstanceState) {
     AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
     builder.setTitle("Choose Font Size");
 }

int the class scope, and call it from the onItemClick

try this one

String[] listItems = {"Colour", "Font Size",};
ListView lv = (ListView) findViewById(R.id.settings_list);

lv.setAdapter(new ArrayAdapter<String>
(this, android.R.layout.simple_list_item_1, listItems));

lv.setOnItemClickListener(new OnItemClickListener()
{
    public void onItemClick(AdapterView<?> parent, View
            view, int position, long id)
    {
        String[] listItems = {"Colour", "Font Size",};
        if(listItems[position].equals("Font Size"))
        {


            AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
            getApplicationContext());

            // set title
            alertDialogBuilder.setTitle("Choose Font Size");

            //create alert dialog
            AlertDialog alertDialog = alertDialogBuilder.create();

            // show it
            alertDialog.show();

        }

    }
});
