IllegalStateException( “You can not set Dialog's OnCancelListener or OnDismissListener”)

Question

This DialogFragment implementation causes an

IllegalStateException( \"You can not set Dialog\'s OnCancelListener or OnDismissListener\")

Answer 1

You set the OnCancelListener for a dialog not for its builder.

public Dialog onCreateDialog(Bundle savedInstanceState){

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder .setTitle(getArguments().getString("title"))
        .setMessage(getArguments().getString("message"))
        .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
            }})
        .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                getDialog().cancel();
            }});

    Dialog dialog = builder.create();
    dialog.setOnCancelListener(onCancelListener);
    return dialog;
}
