材料设计向后兼容 android:颜色使用 appcompat7 时,需要 API 级别 21

2022-09-01 14:54:25

我在eclipse中有一个maven android项目,即使我已经将我的项目配置为使用兼容性库,它仍然在我的样式中给出以下错误.xml:

android:colorAccent requires API level 21 (current min is 15)    
android:colorPrimary requires API level 21 (current min is 15)
android:colorPrimaryDark requires API level 21 (current min is 15)

风格.xml

<style name="AppBaseTheme" parent="Theme.AppCompat"></style>
<style name="AppTheme" parent="AppBaseTheme">

    <item name="android:colorPrimary">@color/primary</item>
    <item name="android:colorPrimaryDark">@color/primary_dark</item>
    <item name="android:colorAccent">@color/accent</item>    

</style>

AndroidManifest.xml

package="com.app"
android:versionCode="1"
android:versionName="0.0.1-SNAPSHOT" >

<uses-sdk
    android:minSdkVersion="15"
    android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.INTERNET"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
    <activity android:name="com.app.activity.MainActivity" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

啪.xml

<build>
    <finalName>${project.artifactId}</finalName>
    <pluginManagement>
        <plugins>
            <plugin>

                <artifactId>android-maven-plugin</artifactId>
                <version>${android.plugin.version}</version>
                <extensions>true</extensions>
            </plugin>
        </plugins>
    </pluginManagement>
    <plugins>
        <plugin>
            <groupId>com.jayway.maven.plugins.android.generation2</groupId>
            <artifactId>android-maven-plugin</artifactId>
            <configuration>
                <sdk>
                    <platform>21</platform>
                </sdk>
            </configuration>
        </plugin>

    </plugins>

</build>

我希望我的应用程序材料设计功能具有向后兼容性支持。我该如何解决这个问题?


答案 2

删除颜色名称前的 android 前缀。因此,它将是:

<item name="colorPrimary">@color/primary</item>
<item name="colorPrimaryDark">@color/primary_dark</item>
<item name="colorAccent">@color/accent</item>
