why custom menu icon is not responding

I want to add a logout option to the tool bar, which has the image view. due to fixed size in tool bar menu, i gone for a custom menu by specifying

app:actionLayout="@layout/custom_menu"

i specified this in my , and did a custom menu in custom_menu.xml.

now when i click the item, i want to perform some task, lets call something like a toast message for testing.

but when i click the in my tool bar, nothing responses.

what am i doing wrong here?

MyJavaActivity.java

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.logout, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.logOut) {
        Toast.makeText(UserActivity.this, "logout clicked", Toast.LENGTH_LONG).show();
        return true;
    }
    return super.onOptionsItemSelected(item);
}

logout.xml (menu for items)

 <?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/logOut"
    android:title="logout"
    app:actionLayout="@layout/custom_menu"
    app:showAsAction="ifRoom">
 </item>
 </menu>
