  }
 }

展開可能なリストに "r.add("E-mail address: \n " + json_data.getString("E-mail" )); " と "r.add("Wachtwoord: \n " + json_data の 2 つを表示します.getString("Wachtwoord" ));. ここで、r.add("E-mail アドレス: \n " + json_data.getString("E-mail" )); が展開可能なリストに赤く表示されるようにします。私はそれをしますか? 何か提案はありますか?

スパン可能な文字列の「電子メール」部分のSpannableStringBuilder代わりに使用StringBuilderして適用できます。TextAppearanceSpan
