我正在尝试将Android Studio项目中的appcompat-v7从v20.0.0更新为21.0.0以使用材料设计组件,但我总是得到同样的错误:

"错误:属性"颜色"已经定义"

我不知道如何解决此错误,我在网上搜索但我无法得到答案.这是我的傻瓜:

android {

    compileOptions.encoding = "iso-8859-1"
    compileSdkVersion 21
    buildToolsVersion "21.1.1"

    defaultConfig {
        applicationId "com.test"
        minSdkVersion 11
        targetSdkVersion 22
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])
 compile 'com.android.support:support-v4:20.0.0'
    compile 'com.google.http-client:google-http-client-gson:1.19.0'
    compile 'com.google.code.gson:gson:2.2.4'
    compile "com.android.support:appcompat-v7:21.0.+"

}

这是冲突存在的路径

C:\Users\Abel Dominguez\Documents\PROYECTOS_ANDROID\definitivos\d2\app\build\intermediates\exploded-aar\com.android.support\appcompat-v7\21.0.3\res\values\values.xml

这是另一个错误:

我正在尝试根据Material Design规则制作CollapsingToolbar动画。一切正常，但一件事情令我沮丧。滚动回收器视图时，我试图更改“折叠的”工具栏的颜色，但是获得的透明颜色始终是相同的...

这是我的xml代码：

<android.support.design.widget.AppBarLayout

        android:fitsSystemWindows="true">

        <android.support.design.widget.CollapsingToolbarLayout

                app:layout_collapseMode="parallax" />

            <android.support.v7.widget.Toolbar

                </android.support.v7.widget.Toolbar>

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

这是我的Java代码

int mutedColor = R.color.gps_friends_green_main;

    Palette.generateAsync(bitmap,
                    new Palette.PaletteAsyncListener() {
                        @Override
                        public void onGenerated(Palette palette) {
                            Palette.Swatch vibrant =
                                    palette.getVibrantSwatch();

                            if (vibrant != null) {
                                // If we have a vibrant color
                                // update the title TextView
                                collapseToolbar.setBackgroundColor(mutedColor);
