内容必须有一个ListView的id属性是'android.R.id.list“ [英] content must have a ListView whose id attribute is 'android.R.id.list'

问题描述

  

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

我得到这个错误，我已经处理过。我已经尝试了很多不同的ID等，但它没有帮助。正如你可以看到下面的名字做似乎是正确的。我认为这是与我是新来的碎片和listfragments等事实。我已经发布code中的相关内容，如果有更多的要求，我会提供它。

任何想法？

您在 ListFragment 的 onCreateView 方法。

出现误导布局

Your content must have a ListView whose id attribute is 'android.R.id.list'

I'm getting this error which I have dealt with before. I have tried a bunch of different ids and so on but it's not helping. As you can see below the names do appear to be correct. I think it has something to do with the fact I am new to fragments and listfragments and so on. I have posted the relevant bits of code, if more is required I will provide it.

Any ideas?

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);
}

}

解决方案

@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;
}

You are giving wrong layout inside ListFragment's onCreateView method.
