我正在努力将这个片段添加到我的XML布局中。
在我的Activity XML布局中，我有以下内容：
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.5"
android:orientation="vertical" >
<fragment
android:id="@+id/fragment_invitefriendsprogress"
android:name="tv.superawesome.club.android.ui.fragments.InviteFriendsProgressFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout="@layout/fragment_invitefriendsprogress" />
</LinearLayout>
我收到一个奇怪的错误：
XML file line #205: Class is not a View android.support.v4.app.Fragment
<fragment
我错过了什么吗？

答案 0 :(得分：8)
而不是......
<android.support.v4.app.Fragment
android:id="@+id/fragment_myfragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.myapp.jimbob.android.ui.fragments.MyFragment"
tools:layout="@layout/fragment_myfragment" />
写得像
<fragment
android:id="@+id/fragment_myfragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.myapp.jimbob.android.ui.fragments.MyFragment" />
您不能直接引用Fragment的xml中的类名，因为它不会扩展View
答案 1 :(得分：3)
更改为
<fragment
android:id="@+id/fragment_myfragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.myapp.jimbob.android.ui.fragments.MyFragment"
/>
您的MyFragment可以延长Fragment，您可以使用SupportLibrary。如果你想使用低于api 11级及以下的片段，请确保你有正确的导入并确保你的活动扩展FragmentActivity。
