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?
我也有同样的问题，让我把我的代码贴出来让你们都能看到，不要做和我一样的事情。
@Override
protected void onResume()
{
super.onResume();
fragManager = getSupportFragmentManager();
Fragment answerPad=getDefaultAnswerPad();
setAnswerPad(answerPad);
setContentView(R.layout.abstract_test_view);
}
protected void setAnswerPad(AbstractAnswerFragment pad)
{
fragManager.beginTransaction()
.add(R.id.AnswerArea, pad, "AnswerArea")
.commit();
fragManager.executePendingTransactions();
}
注意，我在setContentView之前设置了片段。糟糕。
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!
