How Do I Obtain The Setmultichoiceitems Items From My Alertdialog?

I'm using the following code from the apidemos.. return new AlertDialog.Builder(AlertDialogSamples.this) .setIcon(R.drawable.ic_popup_reminder) .set

Solution 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.

Solution 2:

Pass a reference to byte[] in setMultiChoiceItems().

finalboolean[] booleans = {false, true, false, true, false, false, false};

Then check the value of booleans inside setPositiveButton().

If you need to pass this AlertDialog around, then extend AlertDialog and have create a field boolean as described in 1.

Solution 3:

To get checked items when setMultiChoiceItems is used in AlertDialog.Builder, you must create DialogInterface.OnMultiChoiceClickListener with even empty onClick. Only on this condition checkedItems in second params will be used and updated internally in AlertController and reflect checked items on exit (i.e. in setPositiveButton callback)

Check this AlertController code:

...    
} elseif (mOnCheckboxClickListener != null) {
        listView.setOnItemClickListener(new OnItemClickListener() {
            publicvoidonItemClick(AdapterView parent, View v, int position, long id) {
                if (mCheckedItems != null) {
                    mCheckedItems[position] = listView.isItemChecked(position);
                }
                mOnCheckboxClickListener.onClick(
                        dialog.mDialogInterface, position, listView.isItemChecked(position));
            }
        });
    }
...
