i trying enable user stops , starts service implementing menu text changed when clicks want add togglebutton option in menu tool nothing being display in case now. how can fix it?

androidmanifest.xml

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" >      <togglebutton         android:id="@+id/toggle"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:textoff="off"         android:texton="on" /> </menu> 

mainactivity:

public class mainactivity extends actionbaractivity {     togglebutton tbutton;     @override     public boolean oncreateoptionsmenu(menu menu) {         menuinflater inflater = getmenuinflater();         inflater.inflate(r.menu.main_menu, menu);          return true;     }      @override     public boolean onoptionsitemselected(menuitem item) {         switch (item.getitemid()) {             case r.id.toggle:                  tbutton = (togglebutton) findviewbyid(r.id.toggle);                 tbutton.setonclicklistener(new view.onclicklistener() {                      @override                     public void onclick(view v) {                         if (((togglebutton) v).ischecked()) {                             intent = new intent(mainactivity.this,                                                   trackingservice.class);                             startservice(i);                             system.out.println("test checked, start service");                          } else {                             // stop service when menu button clicks.                             intent = new intent(mainactivity.this,                                                   trackingservice.class);                             stopservice(i);                             system.out.println("test not checked, stop service");                          }                      }                 });                  return true;              default:                 return false;         }     } } 

edit:

@override public boolean onoptionsitemselected(menuitem item) {     switch (item.getitemid()) {     case r.id.checkable_menu:         if (ischecked = !item.ischecked()) {             item.setchecked(ischecked);              intent = new intent(this, trackingservice.class);             startservice(i);             system.out.println("test if onoptionsitemselected");         } else {             intent = new intent(this, trackingservice.class);             stopservice(i);             system.out.println("test else onoptionsitemselected");          }         return true;      default:         system.out                 .println("test default onoptionsitemselected invoked.");         return false;     } } 

as mentioned above, can't add toggle button menu. can use android:checkable property in menu item handle 2 states.

something like:

menu:

<item     android:id="@+id/checkable_menu"     android:checkable="true"     android:title="@string/checkable" /> 

activity:

private boolean ischecked = false;  @override public boolean onprepareoptionsmenu(menu menu) {     menuitem checkable = menu.finditem(r.id.checkable_menu);     checkable.setchecked(ischecked);     return true; }  @override public boolean onoptionsitemselected(menuitem item) {     switch (item.getitemid()) {         case r.id.checkable_menu:             ischecked = !item.ischecked();             item.setchecked(ischecked);             return true;         default:             return false;     } } 

ps: copied code here.

or can update item icon on click event show 2 states item.seticon(yourdrawable));
