How do i obtain the setMultiChoiceItems items from my AlertDialog?

Question

I'm using the following code from the apidemos..

        return new AlertDialog.Builder(AlertDialogSamples.this)
            .setIcon(R.drawable.ic_popup_reminder)
            .setTitle(R.string.alert_dialog_multi_choice)
            .setMultiChoiceItems(R.array.select_dialog_items3,
                    new boolean[]{false, true, false, true, false, false, false},
                    new DialogInterface.OnMultiChoiceClickListener() {
                        public void onClick(DialogInterface dialog, int whichButton,
                                boolean isChecked) {

                            /* User clicked on a check box do some stuff */
                        }
                    })
            .setPositiveButton(R.string.alert_dialog_ok, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {

                    /* User clicked Yes so do some stuff */
                }
            })
            .setNegativeButton(R.string.alert_dialog_cancel, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {

                    /* User clicked No so do some stuff */
                }
            })
           .create();

Under /* User clicked Yes so do some stuff */, i'm not fed the isChecked variable.. however, I am given isChecked in the /* User clicked on a check box do some stuff */ section.. Obviously i don't want to update my SharedPrefs on checkbox click, in case the user hits cancel..

So how do I get the checkboxs and values on the setPositiveButton onClick ?

Thanks.

Answer 1

use getListView() of AlertDialog class. and fetch the listView. i.e when you call .create() at the end this will fetch you a new AlertDialog.

Then use one of the following methods:

 1. getCheckItemPositions:SparseBooleanArray
 2. getCheckedItemIds:long[]

I can provide you with demo code. Give me 10-15 mins.
