android - 错误膨胀类 fragment 类未找到 android.view.fragment 但我包括兼容性库？

Question

尽管我使用的是兼容性库，但我看到 android.view.fragment 的类未找到异常。编译正常但崩溃。在 3.0 版之前我应该​​使用另一个包吗？我已经将所有 fragment 类更改为 android.support.v4.app.Frament 但它仍然因为布局中的内容而崩溃。我的 SDK 是 4.03，但设备是 2.3。

这是布局

    <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<fragment
    android:id="@+id/frag_series"
    android:layout_width="200dip"
    android:layout_height="match_parent"
    android:layout_marginTop="?android:attr/actionBarSize"
    class="com.authorwjf.hello_fragments.ListFrag" />
<fragment
    android:id="@+id/frag_capt"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.authorwjf.hello_fragments.DetailFrag" />
</LinearLayout>

Answer 1

在布局 XML 中做同样的事情:

<android.support.v4.app.Fragment />

另外，请注意大小写。
