How do you control the height of the buttons on an Alert Dialog in Android?

I have the following code. How can I make the Neutral Button twice as tall, or Just 开发者_StackOverflowset it's height for that matter. Right now it's too thin and the users are having trouble clicking on it. I don't want to roll my own dialog if I can help it.

int SizeIndex = CurrentState.BaseItem.Sub.indexOf(CurrentState.BaseItem.GetDefaultSize());
CharSequence[] csItems = CurrentState.BaseItem.subNamesToArray();

new AlertDialog.Builder(CurrentState.Activity)              
    .setIcon(R.drawable.icon)
    .setTitle(R.string.prompt_SelectSize)
    .setSingleChoiceItems(csItems,SizeIndex, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    CurrentState.SelectedSize = (ItemSize) CurrentState.BaseItem.Sub.get(which);                                                    
                }
            })
            .setNeutralButton(R.string.alert_dialog_Done, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    if(CurrentState.SelectedSize == null)
                    {
                        CurrentState.SelectedSize  = CurrentState.BaseItem.GetDefaultSize();
                    }
                    CurrentState.Next();
                    dialog.cancel();                        
                }
            })              
            .show();
