Question

Is there a way in Android to display a dialog with a radio button already selected based on environment variable settings?

I wrote the following code. It doesn’t seem to have any errors and I’m pretty sure it executes, but when the dialog is displayed, none of the radio buttons are selected:

switch (shape)
{
    case SQUARE:
        bigCircle.setSelected (false);
        smSircle.setSelected (false);
        if (size == BIG)
        {
            bigSquare.setSelected (true);
            smSquare.setSelected (false);
        }
        else
        {
            bigSquare.setSelected (false);
            smSquare.setSelected (true);
        }
        break;

    case CIRCLE:
        bigSquare.setSelected (false);
        smSquare.setSelected (false);
        if (size == BIG)
        {
            bigCircle.setSelected (true);
            smCircle.setSelected (false);
        }
        else
        {
            bigCircle.setSelected (false);
            smCircle.setSelected (true);
        }
}

dialog.show();

Any suggestions??

Thanks,

Answer 1

do you create your own custom layout for your dialog? (i assume that because of variables bigCircle, smSquare…)

take a look at AlertDialog.Builder’s method setSingleChoiceItems (ListAdapter adapter, int checkedItem, DialogInterface.OnClickListener listener) maybe that would be better way…
