Set default selected item of ListView Alert Dialog in Android

Question

I have created a dialog with a custom ListView that models a Spinner display, and originally it starts out with the value \"Select Gender\".

Figured it out:

I switched from .setAdapter to .setSingleChoiceItems which has an argument for the default selection. Then all I had to do was create a global variable that got set each time I clicked an option. The global variable is initially set to -1 so no option is selected, then once I click on something it gets set to the position and the next time the dialog is created the selection reflects my previous selection. See below:

Integer selection = -1;

genderItems = getResources().getStringArray(R.array.gender_array);
genderAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, genderItems);

genderDrop.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_DOWN) {
                Builder genderBuilder = new AlertDialog.Builder(Register.this)
                    .setTitle(R.string.gender_prompt)
                    .setSingleChoiceItems(genderAdapter, selection, new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            inputGender.setText(genderItems[which]);
                            selection = which;
                            dialog.cancel();
                        }
                    });
                AlertDialog genderAlert = genderBuilder.create();
                genderAlert.show();
            }
            return false;
        }
});
