Android <include layout inside NestedScrollView -


i have coordinatorlayout nestedscrollview. trying include layout inside nestedscrollview however, layout assumes can overlap collaping toolbar. have searched on , not find solution problem. tried including fragment directly instead of layout. failed too. tried including simple textview inside nestedscrollview - worked. problem in include. please me solve it.

doesn't work

   <android.support.v4.widget.nestedscrollview     android:id="@+id/scroll"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:fillviewport="true"     app:layout_behavior="@string/appbar_scrolling_view_behavior">     <include layout="@layout/content_detail"/> </android.support.v4.widget.nestedscrollview>

does work

<android.support.v4.widget.nestedscrollview     android:id="@+id/scroll"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:fillviewport="true"     app:layout_behavior="@string/appbar_scrolling_view_behavior">      <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="hello, working text"/>  </android.support.v4.widget.nestedscrollview>

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
