How to make a custom Dialog Preference inside Preference

I searched all Around this forum , but not getting what i exactly need. I need a Custom DialogPreference in Preference but that DialogPreference shouldn't have blue-strip header which i hate, And i already prepared one activity header template xml file for other activities which can be used as custom activity header.so i want to use that on this dialogPrerence. Plus i want Custom Preference File name but here the problem is it creates two Preference File name, one for Preference and Another for DialogPreference

but i found something like this here Using EditTextPreference with 2 user input fields

    <com.yourdomain.YourDialogPreference
        android:title="Title"
        android:summary="Summary"
        android:key="dialog_preference"/>

i 've done so far with this. DialogPreference Opens well, but how can i attach my header template to this custom DialogPreference
