android - Can't toggle switch in Custom SwitchPreference -

i try custom switch preference in adroid. here code

 switch_widget.xml <switch xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/customswitch"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:focusable="false"    android:clickable="false"     />   preference xml file :  <com.tnavitech.utils.customswitch        android:title="hide app icon"         android:key="hideicon"        android:defaultvalue="false"        android:disabledependentsstate="true"        android:widgetlayout="@layout/switch_widget"      /> 

then extend "switchpreference", , in "onbindview" class, , handle switch states in onpreferencechangelistener :

public class customswitch extends switchpreference {      switch swit;      public customcheckbox(context context, attributeset attrs) {     super(context, attrs);     }  @override protected void onbindview(final view rootview) {     viewgroup viewgroup= (viewgroup)rootview;     super.onbindview(rootview);      if(swit==null){          swit  = (switch) rootview.findviewbyid(r.id.customswitch);     }      this.setonpreferencechangelistener(new onpreferencechangelistener() {         @override         public boolean onpreferencechange(preference arg0, object arg1) {              if (arg1 instanceof boolean) {                 boolean enabled = (boolean) arg1;                 if(enabled){                     swit.setchecked(true); /// cant toggle switch here                     toast.maketext(getcontext(), "on", toast.length_short).show();                   } else {                     toast.maketext(getcontext(), "off", toast.length_short).show();                      swit.setselected(false);     ///cant toggle switch here             }             }                return true;         }     });  } 

in setonpreferencechangelistener cant toggle swith on or off. how solve this? thanks!

i'm working on app running on device api 15 had fix issue. solution have 2 different layouts switchpreference instead of 1 handles switch toggling. switch needs clickable = false otherwise switchpreference won't handle clicks.

first 'on state' switch layout, button uses drawable represents on button:

<?xml version="1.0" encoding="utf-8"?> <switch xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/custom_switch_item"     android:layout_width="48dp"     android:layout_height="wrap_content"     android:textcolor="@android:color/white"     android:textisselectable="false"     android:textsize="0sp"     android:button="@drawable/ico_toggle_on" //here difference between these layouts     android:thumb="@android:color/transparent"     android:track="@android:color/transparent"     android:clickable="false"     android:focusable="false"     android:gravity="center_vertical" /> 

second layout off state:

<?xml version="1.0" encoding="utf-8"?> <switch xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/custom_switch_item"     android:layout_width="48dp"     android:layout_height="wrap_content"     android:textcolor="@android:color/white"     android:textisselectable="false"     android:textsize="0sp"     android:button="@drawable/ico_toggle_off" //here difference between these layouts     android:thumb="@android:color/transparent"     android:track="@android:color/transparent"     android:clickable="false"     android:focusable="false"     android:gravity="center_vertical" /> 

and in activity or fragment set on switchpreference onpreferencechangelistener switch these 2 layouts this:

final switchpreference expertsettingspref = (switchpreference) findpreference("expert_settings");     if (expertsettingspref != null) {         expertsettingspref.setonpreferencechangelistener(new preference.onpreferencechangelistener() {             @override             public boolean onpreferencechange(preference preference, object newvalue) {                 preference.setwidgetlayoutresource((boolean)newvalue ? r.layout.custom_switch_preference_on : r.layout.custom_switch_preference_off);                 return true;             }         });     }
