我有一个片段,我试图添加到一个视图。
FragmentManager fragMgr=getSupportFragmentManager();
feed_parser_activity content = (feed_parser_activity)fragMgr
.findFragmentById(R.id.feedContentContainer);
FragmentTransaction xaction=fragMgr.beginTransaction();
if (content == null || content.isRemoving()) {
content=new feed_parser_activity(item.getLink().toString());
xaction
.add(R.id.feedContentContainer, content)
.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
.addToBackStack(null)
.commit();
Log.e("Abstract", "DONE");
}
当这段代码执行时,我在调试中得到以下错误。
java.lang.IllegalArgumentException: No view found for id 0x7f080011
for fragment feed_parser_activity{41882f50 #2 id=0x7f080011}
feed_parser_activity是一个片段,在xml中被设置为片段布局。
我使用FragmentActivity来托管持有feed_parser_layout的片段布局。
我上面写的对吗?
我从com.android.support:support-v4:21.0.0升级到com.android.support:support-v4:22.1.1时遇到了这个错误。
我不得不改变我的布局:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/container_frame_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/container_frame_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
</FrameLayout>
所以布局必须有一个子视图。我猜他们在新图书馆里强制这么做了。
这个页面似乎是发布关于片段IllegalArgumentException的建议的一个很好的中心位置。还有一件事你可以试试。这是最后对我有用的方法:
我忘了我有一个单独的横向布局文件。在我添加了我的FrameLayout容器之后,这个片段也工作了。
On a separate note, if you have already tried everything else suggested on this page (and the entire Internet, too) and have been pulling out your hair for hours, consider just dumping these annoying fragments and going back to a good old standard layout. (That's actually what I was in the process of doing when I finally discovered my problem.) You can still use the container concept. However, instead of filling it with a fragment, you can use the xml include tag to fill it with the same layout that you would have used in your fragment. You could do something like this in your main layout:
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<include layout="@layout/former_fragment_layout" />
</FrameLayout>
其中former_fragment_layout是您试图在片段中使用的XML布局文件的名称。有关更多信息,请参见使用include重用布局。
