no resource id found for app:layout_scrollflags from CollapsingToolbarLayout

Question

The title of this question basically says it all. I get the error: no resource identifier found for app:layout_scrollflags from CollapsingToolbarLayout. I use eclipse and imported the design library jar file. I'm able to use the design support layouts in my classes so that's correct

this is a piece of the code i use:

<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:background="@color/activityBg" tools:context=".MainActivity" >  <android.support.design.widget.AppBarLayout     android:layout_height="wrap_content"     android:layout_width="match_parent">      <android.support.design.widget.CollapsingToolbarLayout             android:layout_width="match_parent"             android:layout_height="match_parent"             app:layout_scrollFlags="scroll|exitUntilCollapsed">          <include             layout="@layout/toolbar"/>      </android.support.design.widget.CollapsingToolbarLayout> </android.support.design.widget.AppBarLayout>

Answer 1

only importing the design library jar file is not enough. You need to import resource of android-design-library project while the jar file only contains class files.

Do as I say:

1. import android-design-library project. The project is at "sdk/extras/android/support/design/". And set it as a library project if it is not.
2. import the above project into your main project as a library.

You have to do this, because xmlns:app="http://schemas.android.com/apk/res-auto" means your need local resources from your library project or the current project, in this case, it means you need resources from the library project of android-design-library.
