错误膨胀类片段 - 重复的 ID/非法参数异常? [英] Error inflating class fragment - duplicate id/illegalargumentexception?
问题描述
我正在尝试制作一个我正在构建的应用程序，从主要活动中获取搜索词，返回结果，然后让结果可点击，以便可以从每个结果中查看详细信息.我通过使用 MainActivity、ResultsActivity 和 PlaceActivity，然后使用 ListFragmentClickable(它扩展了 ListFragment)来完成此操作.如果手机是纵向模式，结果列表应该是可见的，只有在点击结果时才能查看详细信息.If the handset is landscape, a detail window should pop up to the right of the list when an item is selected.
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，我收到一条错误消息，内容为错误膨胀类片段".我不知道是什么原因造成的，我很乐意帮助您摆脱它.
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.
我的 ListFragmentClickables 被我的 ResultsActivity 调用，它在这里:
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);
}
}
}
这是 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!!
}
}
这是我的 ResultsActivity 布局文件 (activity_results_activity.xml):
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>
最后是日志:

非常感谢所有帮助.如果还有什么我可以补充的，请告诉我?
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 上的片段加载了两次，第二次将它添加到 FragmentManager 时，您会收到 IllegalArgumentException.我昨天遇到了同样的问题.
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，我将其更改为动态重新创建片段，而不是在 xml 文件中定义它:
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>
改为:
<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" />
然后在 onCreate 中，您应该将 FrameLayout 替换为新片段:
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();
然后你有同样的但是，你不会得到重复的 ID 错误.
And then you have the same but, you won't get a Duplicate ID error.
