작업 모음의 SwitchCompat, 단편으로

Question

SwitchCompat을 작업 표시 줄로 설정하려고 할 때 오류가 발생합니다. 여기

여기의 onCreateOptionsMenu 조각에서 내 abswitch.xml

다음

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/abswitch" 
    android:layout_width="fill_parent" 
    android:layout_height="match_parent" 
    android:orientation="horizontal" > 

    <android.support.v7.widget.SwitchCompat 
     android:id="@+id/switchForActionBar" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerVertical="true" 
     android:text="" /> 

</RelativeLayout> 

내 profile_menu.xml

<?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/myswitch" 
     android:title="" 
     app:showAsAction="always" 
     android:actionLayout="@layout/abswitch"/> 
</menu> 

하고

다음

@Override 
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { 
    inflater.inflate(R.menu.profile_menu, menu); 
    MenuItem item = menu.findItem(R.id.myswitch); 
    item.setActionView(R.layout.abswitch); 
    SwitchCompat switchCompat = (SwitchCompat) item.getActionView(); 
    super.onCreateOptionsMenu(menu, inflater); 
}

미리 감사드립니다.

P. 붙여 넣기 링크를 사용하여 죄송합니다. xml의 서식을 올바르게 지정하지 않았습니다.

EDIT : 알아 냈습니다.

는

<item 
    android:id="@+id/toggleservice" 
    app:actionViewClass="android.support.v7.widget.SwitchCompat" 
    app:showAsAction="always" 
    android:title=""/> 

지금

@Override 
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { 
    inflater.inflate(R.menu.profile_menu, menu); 
    MenuItem item = menu.findItem(R.id.toggleservice); 
    SwitchCompat switchCompat = (SwitchCompat) MenuItemCompat.getActionView(item); 
    super.onCreateOptionsMenu(menu, inflater); 
} 

의 작업 Profile.class

에서 profile_menu.xml

에서 변경되었습니다. 감사합니다 여러분!

SwitchCompat switchCompat = (SwitchCompat) MenuItemCompat.getActionView(item);
