无法将片段加载到活动中

时间：2015-01-06 22:40:42

标签： java android

我正在尝试将abmob广告添加到我的Android应用中的某个活动中，但该片段无法加载。当应用程序加载它崩溃并说“无法启动活动时”ComponentInfo {catchmedia.jamaica.dictionary / catchmedia.jamaica.dictionary.HomeActivity}：android.view.InflateException：二进制XML文件行＃15：错误膨胀类片段。我做错了什么？

答案 0 :(得分：0)

当您的AdFragment从android.support.v4.Fragment扩展时，您应该将片段更改为xml文件中的android.support.v4.Fragment。

答案 1 :(得分：0)

在您的HomeActivity课程中，您已导入android.support.v4.app.Fragment，android.support.v4.app.FragmentActivity等。此处存在冲突。

在您的XML中，您使用的是<fragment>。您需要将导入更改为android.app.Fragment，或将XML更改为：

<android.support.v4.app.fragment
    android:id="@+id/adFragment"
    android:name="catchmedia.jamaica.dictionary.HomeActivity$AdFragment"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true" />

如果您正在使用片段，并希望在API 11 之前定位设备，则应该使用android.support.v4.app.Fragment。但是，如果您只定位运行API 11或更高版本的设备，则可以使用android.app.Fragment。

否则，您使用Android支持库中的Fragment和Fragment之间存在冲突。
