内容必须有一个ListView其id属性为 'android.R.id.list'

Question

您的内容必须有一个ListView，其id属性是 'android.R.id.list'

我我得到了以前处理过的这个错误。我已经尝试了一堆不同的ID等等，但它没有帮助。正如你在下面看到的名字看起来是正确的。我认为这与我对碎片和列表碎片等有新意的事实有关。我已经发布了相关的代码，如果需要更多，我会提供它。

任何想法？

public class DisplayInfo extends FragmentActivity { 


SectionsPagerAdapter mSectionsPagerAdapter; 

/** 
* The {@link ViewPager} that will host the section contents. 
*/ 
ViewPager mViewPager; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_display_info); 

    mSectionsPagerAdapter = new SectionsPagerAdapter(
      getSupportFragmentManager()); 

    new CreateTimetablesTask().execute(); 
    Log.d("task done", "task"); 
    // Set up the ViewPager with the sections adapter. 
    mViewPager = (ViewPager) findViewById(R.id.pager); 
    mViewPager.setAdapter(mSectionsPagerAdapter); 

} 

}

public class DummySectionFragment extends ListFragment { 
private Integer arrayListId; 
ViewGroup myViewGroup; 
public static final String CATEGORY_POSITION = "section_number"; 
public static DummySectionFragment newInstance(int pos) { 
    DummySectionFragment f = new DummySectionFragment(); 

    // Supply num input as an argument. 
    Bundle args = new Bundle(); 
    args.putInt(CATEGORY_POSITION, pos); 
    f.setArguments(args); 

    return f; 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    //get the id for your array list 
    super.onCreate(savedInstanceState); 
    arrayListId = getArguments() != null ? getArguments().getInt(CATEGORY_POSITION) - 1 : 1; 
} 

//create the list view layout 
@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    myViewGroup = container; 
    View v = inflater.inflate(R.layout.list_row, container, false); 
    return v; 
} 

@Override 
public void onActivityCreated(Bundle savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 
    ArrayAdapter<SingleClass> arrayAdapter =  
new ArrayAdapter<SingleClass>(getActivity(), R.layout.fragment_display_info, android.R.id.list); 

    setListAdapter(arrayAdapter); 
} 

}

Answer 1

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    myViewGroup = container; 
    View v = inflater.inflate(R.layout.fragment_display_info, container, false); 
    return v; 
} 

你给内部ListFragment的onCreateView方法错布局。
