<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto">      <item android:id="@+id/toggle_loc"         android:title=""         android:visible="true"         app:actionlayout="@layout/switch_button"         app:showasaction="ifroom">      </item>  </menu> 

layout/switch_button"

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="wrap_content" android:layout_height="wrap_content">      <switch         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/switch_location"         android:enabled="true"         android:checked="true"          />   </relativelayout> 

please me make switch checked default.

use

switchbutton.setchecked(true); 

also doing wrong like:

switch switchbutton=new switch(getactivity()); 

instead should do

switch switchbutton = (switch) switchitem.getactionview().findviewbyid(r.id.switch_location); 

so should like:

switch switchbutton = (switch) switchitem.getactionview().findviewbyid(r.id.switch_location); switchbutton.setchecked(true);
