Change Android settings icon with SwitchPreference setting

Question

I have an application SwitchPreferencein my Android application that can be installed on " on" or " off". I have an icon for this SwitchPreference. Xml code below

<SwitchPreference
    android:title="@string/psm_pinterest"
    android:defaultValue="false"
    android:key="@string/pref_social_pinterest"
    android:icon="@drawable/pinterest_bw"
    android:summaryOn="@string/psm_pinterest_summary_on"
    android:summaryOff="@string/psm_pinterest_summary_off"/>

However, I also want to iconchange how and when it SwitchPreferencewas changed. Is there any way to do this through XML? I tried to create an drawablexml using the state settings, but none of the states are called when I change the parameter SwitchPreference.

Now I am processing this programmatically, but I am considering a more efficient way to do this using XML itself. Rate help
