从CollapsingToolbarLayout找不到app:layout_scrollflags的资源ID [英] no resource id found for app:layout_scrollflags from CollapsingToolbarLayout

问题描述

这个问题的标题基本上说明了一切.我得到了错误: 在CollapsingToolbarLayout中找不到app:layout_scrollflags的资源标识符.我使用eclipse并导入了设计库jar文件.我可以在班级中使用设计支持布局，这是正确的

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

这是我使用的一部分代码:

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>

推荐答案

仅导入设计库jar文件是不够的.您需要导入 android-design-library 项目的资源，而jar文件仅包含类文件.

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.

按我说的做:

1. 导入 android-design-library 项目.该项目在 " sdk/extras/android/support/design/".并将其设置为库 项目，如果不是.
2. 将上述项目作为库导入到您的主项目中.

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.

您必须执行此操作，因为xmlns:app="http://schemas.android.com/apk/res-auto"表示您需要库项目或当前项目中的本地资源，在这种情况下，这意味着您需要来自 android-design-library库项目中的资源.

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.
