Android设计支持库设置麻烦

Question

I'm completely confused with implementation of the Android design support library. I tried to do almost everything advised on Stack Overflow, but I am still having compile-time errors on each widget from the design support library (Error parsing XML: Unbound prefix).

I'm developing in Eclipse. Here's what have I done:

1. Downloaded last Android Support Library (23.0.1), Android Support Repository (21), API 23.

2. Imported android-support-v7-appcompat as a library,
   Project Properties - Android - Add.

3. Copied last downloaded android-support-design.jar ,
   android-support-v4.jar , android-support-v7.jar
   into libs folder of the project and imported them as: Profect Properties - Java Build Path - Libraries Add Jars and checked them on Order and Export.

4. I set up targetSdkVersion="23" in manifest, target=android-23 in project.properties.

5. Changed theme in styles.xml as:

My layout looks like this:

<android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="192dp" >

    <android.support.design.widget.CollapsingToolbarLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_scrollFlags="scroll|exitUntilCollapsed" >

        <android.support.v7.widget.Toolbar
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin" />
    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>

Any suggestions?

No doubt Android Studio is Good for Android development but still have a solution for this problem in eclipse. I have also face same problem then find solution like this.

It work for me hope same for You.

First Step:- find .aar file for design-23.0.1.aar

E:\new sdk\sdk\android-sdk-windows\extras\android\m2repository\com\android\support\design\23.0.1 

Second Step:- copy that file and rename it like design-23.0.1.jar to be extract this. After unzip it you find classes.jar, res, AndroidManifest etc and follow these steps: Guided by commonsware.com

• Create an empty directory that will be the home for the Android library project. For the rest of these steps, I will refer to this as “the output directory”.
• Copy the AndroidManifest.xml , res/ , and assets/ directories from the AAR into the output directory.
• Create a libs/ directory in the output directory. Copy into libs/ the classes.jar from the root of the unZIPped AAR, plus anything in libs/ in the AAR (eg, mediarouter-v7 has its own JAR of proprietary bits).
• Decide what build SDK you want to try to use. You might just choose the highest SDK version you have installed. Or, you can use the android:minSdkVersion and the -vNN resource set qualifiers to get clues as to what a good build SDK might be. If desired, create a project.properties file with a target=android-NNN line, where NNN is your chosen build SDK. Or, you can address this in Eclipse later on.
• Import the resulting project into Eclipse, and if needed adjust the build SDK (Project > Properties > Android). Also, you will need to attach to this library project any library projects it depends upon (eg, mediarouter-v7 depends upon appcompat-v7).

Good Luck!

And Special thanks to commonsware !!

Start using Android Studio. The whole library management is very good of Android Studio. The support for eclipse is going to end from google so anyhow you have to switch.

Hey you are attaching android-support-v7-appcompat for two times. Just use it only one time either use as library and add in properties OR put lib file in libs folder.

Just remove only one and try to clean and rebuild project again. :)
