ラジオボタンから値を渡すことができましたが、ユーザーがいくつかのチェックボックスをクリックして、チェックされた値をトーストビューに表示するときに必要です +トッピング: HERE

多分これはうまくいくでしょうか?

result.append("Pepperoni").append(pep.isChecked().toString());
result.append("Mushrooms").append(mshr.isChecked().toString());

次のような意味ですか。

if (pep.isChecked())
   result.append("Pepperoni, ");
if (mshr.isChecked())
   result.append("Mushrooms, ");
if (result.length() > 2)
   result.delete(result.length() - 2, result.length()); // to remove last ", "
