错误充气类片段 - 重复ID /抛出：IllegalArgumentException？ [英] Error inflating class fragment - duplicate id/illegalargumentexception?
问题描述
我试图做我正在考虑建设从主要活动搜索词，返回结果的应用程序，然后有结果可以点击这样一个细节可以从每个结果进行查看。我用MainActivity，一个ResultsActivity和PlaceActivity再ListFragmentClickable（延伸ListFragment）这样做。如果手机是在纵向模式为导向，结果列表应该是可见的，只有当点击一个结果正在查看的细节。如果手机的景观，当选择的项目的详细信息窗口应弹出列表的右侧。
I'm trying make an app that I'm building take a search term from the main activity, return results, and then have the results be clickable such that a detail could be viewed from each results. I'm doing this by using a MainActivity, a ResultsActivity, and PlaceActivity and then a ListFragmentClickable (which extends ListFragment). If the handset is oriented in portrait mode, the results list should be viewable, with the details being viewed only if a result is clicked. If the handset is landscape, a detail window should pop up to the right of the list when an item is selected.
在运行时，我得到的，上面写着错误充气类片段一个错误。我不知道是什么原因造成的，我很乐意帮助摆脱它。
At runtime, I get an error that reads "error inflating class fragment". I have no idea what is causing it, and I'd love help in getting rid of it.
我ListFragmentClickables由我ResultsActivity，这就是这里所说的：
My ListFragmentClickables are called by my ResultsActivity, which is here:
public class ResultsActivity extends FragmentActivity implements ListFragmentClickable.OnItemSelectedListener{
private ArrayAdapter<String> mAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_results_view);
//Receive searchTerm from MainActivity
Intent intent = getIntent();
String searchTerm = intent.getStringExtra(MainActivity.SEARCH_TERM);
mAdapter = new ArrayAdapter<String>(this, R.layout.item_label_list);
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
FactualResponderFragment responder = (FactualResponderFragment) fm.findFragmentByTag("RESTResponder");
if (responder == null) {
responder = new FactualResponderFragment();
ft.add(responder, "RESTResponder");
}
Bundle bundle = new Bundle();
bundle.putString("search_term", searchTerm);
responder.setArguments(bundle);
ft.commit();
}
public ArrayAdapter<String> getArrayAdapter() {
return mAdapter;
}
@Override //creates a DetailFragment when a list item is selected
public void onItemSelected(String link) {
DetailFragment fragment = (DetailFragment) getSupportFragmentManager().findFragmentById(R.id.detailFragment);
if (fragment != null && fragment.isInLayout()) {
fragment.setText(link);
} else {
Intent intent = new Intent(getApplicationContext(), PlaceActivity.class);
intent.putExtra(PlaceActivity.EXTRA_URL, link);
startActivity(intent);
}
}
}
这里的ListFragmentClickable类：
Here's the ListFragmentClickable class:
public class ListFragmentClickable extends ListFragment{
private OnItemSelectedListener listener;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_results_view, container, false);
return view;
}
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
updateDetail(); //see bottom
}
public interface OnItemSelectedListener {
public void onItemSelected(String link);
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
if (activity instanceof OnItemSelectedListener) {
listener = (OnItemSelectedListener) activity;
} else {
throw new ClassCastException(activity.toString()
+ " must implemenet ListFragmentClickable.OnItemSelectedListener");
}
}
public void updateDetail() {
// Create fake data
String newTime = String.valueOf(System.currentTimeMillis());
// Send data to Activity
listener.onItemSelected(newTime); //should direct PlaceActivity!!
}
}
下面是为ResultsActivity（activity_results_activity.xml）我的布局文件：
Here's my layout file for the ResultsActivity (activity_results_activity.xml):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<fragment
android:id="@+id/fragment_content"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_marginTop="?android:attr/actionBarSize"
class="com.example.blobtag2.ListFragmentClickable" ></fragment>
<ListView
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:divider="#b5b5b5"
android:dividerHeight="1dp"></ListView>
</LinearLayout>
最后，这里的日志：

任何及所有帮助是很大的，大大AP preciated。请让我知道如果有什么我可以加？
Any and all help is greatly, greatly appreciated. Please let me know if there's anything else I can add?
推荐答案
问题是XML的片段被加载两次，并且被添加到FragmentManager你第二次得到一个IllegalArgumentException异常。我昨天得到了同样的问题。
The problem is the fragment on xml is loaded twice, and the second time it is added to the FragmentManager you get a IllegalArgumentException. I got the same problem yesterday.
我的解决方案，我将其更改为重新创建片段动态，而不是把它定义的XML文件：
My solution, I change it to re-create the fragment dynamically instead of define it on the xml file:
更改此xml文件的一部分：
Change this xml file part:
<fragment
android:id="@+id/fragment_content"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_marginTop="?android:attr/actionBarSize"
class="com.example.blobtag2.ListFragmentClickable" ></fragment>
要这个代替：
<FrameLayout
android:id="@+id/fragment_content"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_marginTop="?android:attr/actionBarSize" />
这是然后在OnCreate，哟应该更换的FrameLayout新片段：
An then in the onCreate, yo should replace FrameLayout for a new fragment:
Fragment fragment = new ListFragmentClickable();
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.fragment_content, fragment);
ft.commit();
然后你有相同的，但是，你不会得到一个重复ID错误。
And then you have the same but, you won't get a Duplicate ID error.
