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?
当我试图用onCreateView()中的片段替换视图时，我遇到了这个问题。是这样的:
public class MyProjectListFrag extends Fragment {
private MyProjectListFragment myProjectListFragment;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
FragmentManager mFragmentManager = getFragmentManager();
myProjectListFragment = new MyProjectListFragment();
mFragmentManager
.beginTransaction()
.replace(R.id.container_for_my_pro_list,
myProjectListFragment, "myProjectListFragment")
.commit();
}
它告诉我
11-25 14:06:04.848: E/AndroidRuntime(26040): java.lang.IllegalArgumentException: No view found for id 0x7f05003f (com.example.myays:id/container_for_my_pro_list) for fragment MyProjectListFragment{41692f40 #2 id=0x7f05003f myProjectListFragment}
然后我修复了这个问题，把替换到onActivityCreated()。是这样的:
public class MyProjectListFrag extends Fragment {
private final static String TAG = "lch";
private MyProjectListFragment myProjectListFragment;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater
.inflate(R.layout.frag_my_project_list, container, false);
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
FragmentManager mFragmentManager = getFragmentManager();
myProjectListFragment = new MyProjectListFragment();
mFragmentManager
.beginTransaction()
.replace(R.id.container_for_my_pro_list,
myProjectListFragment, "myProjectListFragment")
.commit();
}
你必须在onCreateView()中返回一个视图，以便稍后替换它
你可以在fragment liftcycle中的以下函数中对这个视图进行任何操作，比如onActivityCreated()
希望这能有所帮助!
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。
