这是我在settings_item_head.xml中的内容(这是错误所在)

<include xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/list_item_section_text"
    layout="@android:layout/preference_category" />

这是我的适配器:

public class EntryAdapter extends ArrayAdapter {
    private Context context;
    private ArrayList items;
    private LayoutInflater vi;

    public EntryAdapter(Context context, ArrayList items) {
        super(context, 0, items);
        this.context = context;
        this.items = items;
        vi = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = convertView;
        final Item i = (Item) items.get(position);
        if (i != null) {
            if (i.isSection()) {
                SectionItem si = (SectionItem) i;
                v = vi.inflate(R.layout.settings_item_head, null);
                v.setOnClickListener(null);
                v.setOnLongClickListener(null);
                v.setLongClickable(false);
                final TextView sectionView = (TextView) v
                        .findViewById(R.id.list_item_section_text);
                sectionView.setText(si.getTitle());
            } else {
                EntryItem ei = (EntryItem) i;
                v = vi.inflate(R.layout.settings_item_item, null);
                final TextView title = (TextView) v
                        .findViewById(R.id.list_item_entry_title);
                final TextView subtitle = (TextView) v
                        .findViewById(R.id.list_item_entry_summary);
                if (title != null)
                    title.setText(ei.title);
                if (subtitle != null)
                    subtitle.setText(ei.subtitle);
            }
        }
        return v;
    }
}

也许不是一个解决方案，但如果您的帖子不是复制/粘贴问题，则您的layout.xml有点错误。您有帖子:

     <include xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/list_item_section_text"
     layout="@android:layout/preference_category" />

但是，教程看起来像这样:

     <linearlayout android:layout_height="wrap_content"
     android:layout_width="fill_parent" 
     android:orientation="vertical" 
     xmlns:android="http://schemas.android.com/apk/res/android">
     <include android:id="@+id/list_item_section_text" 
     layout="@android:layout/preference_category">
     </include>
     </linearlayout>

因此，如果您的 xml 帖子是教程中相同内容的一部分，您必须删除:

    xmlns:android="http://schemas.android.com/apk/res/android"

来自您的包含。必须将其放置在 LinearLayout 内。另外，如果这确实是您的错，请在更改后清理项目。
