无法在Fragment中调用getChildFragmentManager

标签: java android maven android-nested-fragment

我正在用maven构建android项目。但是当我在getChildFragmentManager中调用v4.Fragment时,我发现它找不到找不到此方法的错误。我怀疑support-v4包不够新,因为如果我使用ant来构建我的项目,一切都运行正常。

但是我无法将更新的support-v4包含在我的项目中。 这是我的pom.xml

我被这几个小时难过了(这就是为什么我还加了赏金),但这就是我最终解决它的原因。

首先,使用

检查项目的类路径依赖项
mvn dependency:build-classpath

我可以立即在输出中看到问题:

<home>/.m2\repository\android\extras\android-support\v4\android-support-v4.jar
<home>/.m2\repository\android\platforms\android\android-18\android-android-18.jar
<home>/.m2\repository\com\actionbarsherlock\actionbarsherlock\4.4.0\actionbarsherlock-4.4.0.apklib
<home>/.m2\repository\com\google\android\support-v4\r7\support-v4-r7.jar
<... more jars>

包含两个支持jar,support-v4-r7.jar会覆盖我的android-support-v4.jar

在我的项目中,ActionBarSherlock正在加载旧版本(在你的项目中,罪魁祸首可能是任何apklib依赖项),所以我把它排除在我的项目pom中:

<dependency>
        <groupId>com.actionbarsherlock</groupId>
        <artifactId>actionbarsherlock</artifactId>
        <version>4.4.0</version>
        <type>apklib</type>
        <exclusions>
            <exclusion>
                <groupId>com.google.android</groupId>
                <artifactId>support-v4</artifactId>
            </exclusion>
        </exclusions>
</dependency>

希望这有助于某人。
