Hello,
I have an AlertDialog with single choice items, but these items
sometimes change, so I have to update the radio buttons every time
when the dialog is showed.
I know there is a method called onPrepareDialog but the dialog doesn't
have the setSingleChoiceItems, only the Builder.
Here is my onCreateDialog:
protected Dialog onCreateDialog(int id) {
Dialog dialog;
case DIALOG_SOMETHING:
{
final CharSequence[] radiobuttons;
int checked;
//... here I fill radiobuttons array and set the
checked item.
// create dialog
AlertDialog.Builder builder = new
AlertDialog.Builder(this);
builder.setTitle("title")
.setSingleChoiceItems(radiobuttons, checked, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int radioitem)
{
// ...
}
})
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id)
{
// ...
}
});
dialog = builder.create();
break;
}
default:
dialog = null;
}
return dialog;
}
If I copy this code to onPrepareDialog, nothing happens. :-( The
dialog doesn't update my radiobuttons.
What can I do?
Evi
