よりも優先画面に別々に示し百聞は一見にしかずで、これは私の問題です：カスタムプリファレンスは、ネイティブ環境設定
最後の三つの好みは、分、秒 のカスタム時間ピッカーです他の設定は、通常のSwitchPreferenceは、RingTonePreference、ListPreferenceとEditTextPreference
これは私の好みのXMLである

長めですのでTimePickerPreferenceコードは入れません。
私はコード内の任意の場所にレイアウトを設定していませんので、組み込みの設定と同じように表示されることを期待していますが、上記の図のように異なります。
カスタム設定項目が通常の設定と異なる理由は何ですか？
