Java 膨胀类TextView时出现可扩展Listview错误

我在我的主要

活动中使用了材料设计
tablayout
，在那里我有
可滚动的
选项卡，在我的第一个
片段中我使用了可扩展的
列表视图

这是我的片段代码

public class House_Hold_List_Fragment extends Fragment {
    ExpandableListAdapter listAdapter;
    ExpandableListView expListView;
    List<HouseHoldList_Model> listDataHeader;
    HashMap<HouseHoldList_Model, List<String>> listDataChild;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view=inflater.inflate(R.layout.house_hold_list_fragment, container, false);
        setHasOptionsMenu(true);
        expListView = (ExpandableListView) view.findViewById(R.id.lvExp);
        listDataHeader = new ArrayList<HouseHoldList_Model>();
        listDataChild = new HashMap<HouseHoldList_Model, List<String>>();
        loadModel();
        // preparing list data
        prepareListData();

        listAdapter = new ExpandableListAdapter(getActivity(), listDataHeader, listDataChild);

        // setting list adapter
        expListView.setAdapter(listAdapter);
        return view;
    }

    public void prepareListData(){
        List<String> top250 = new ArrayList<String>();
        top250.add("The Shawshank Redemption");
        top250.add("The Godfather");
        top250.add("The Godfather: Part II");
        top250.add("Pulp Fiction");
        top250.add("The Good, the Bad and the Ugly");
        top250.add("The Dark Knight");
        top250.add("12 Angry Men");

        List<String> nowShowing = new ArrayList<String>();
        nowShowing.add("The Conjuring");
        nowShowing.add("Despicable Me 2");
        nowShowing.add("Turbo");
        nowShowing.add("Grown Ups 2");
        nowShowing.add("Red 2");
        nowShowing.add("The Wolverine");

        List<String> comingSoon = new ArrayList<String>();
        comingSoon.add("2 Guns");
        comingSoon.add("The Smurfs 2");
        comingSoon.add("The Spectacular Now");
        comingSoon.add("The Canyons");
        comingSoon.add("Europa Report");

        listDataChild.put((HouseHoldList_Model)listDataHeader.get(0), top250); // Header, Child data
        listDataChild.put(listDataHeader.get(1), nowShowing);
        listDataChild.put(listDataHeader.get(2), comingSoon);

    }

    public void loadModel(){
        listDataHeader.add(new HouseHoldList_Model("A"));
        listDataHeader.add(new HouseHoldList_Model("B"));
        listDataHeader.add(new HouseHoldList_Model("C"));
    }

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        // TODO Auto-generated method stub
        //super.onCreateOptionsMenu(menu, inflater);
        inflater.inflate(R.menu.menu, menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        switch (item.getItemId()) {
            case R.id.search:
                //do something
                Log.e("search clicked","sd");
                return true;

            case R.id.action_settings:
                //do something
                Log.e("search clicked","sd");
                return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

这是我的ExpandableListAdapter类代码

public class ExpandableListAdapter extends BaseExpandableListAdapter {

    private Context _context;
    private List<HouseHoldList_Model> _listDataHeader; // header titles
    // child data in format of header title, child title

        final String childText = (String) getChild(groupPosition, childPosition);

        if (convertView == null) {
            LayoutInflater infalInflater = (LayoutInflater) this._context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = infalInflater.inflate(R.layout.house_holld_list_item, null);
        }

        TextView txtListChild = (TextView) convertView
                .findViewById(R.id.house_hold_list_item);

        txtListChild.setText(childText);
        return convertView;
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        return this._listDataChild.get(this._listDataHeader.get(groupPosition))
                .size();
    }

    @Override

    }

    @Override

    }

    @Override

        return groupPosition;
    }

    @Override
    public View getGroupView(int groupPosition, boolean isExpanded,
                             View convertView, ViewGroup parent) {
        HouseHoldList_Model model = (HouseHoldList_Model) getGroup(groupPosition);
        if (convertView == null) {
            LayoutInflater infalInflater = (LayoutInflater) this._context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = infalInflater.inflate(R.layout.house_hold_list_row, null);
        }
        TextView lblListHeader = (TextView) convertView
                .findViewById(R.id.house_hold_name);
        lblListHeader.setText(model.name);

        return convertView;
    }

    @Override
    public boolean hasStableIds() {
        return false;
    }

    @Override
    public boolean isChildSelectable(int groupPosition, int childPosition) {
        return true;
    }
}

在我看来，您的textview无法引用convertView，因此请在if（）条件下使用它，然后尝试下面的代码

    if (convertView == null) {
            LayoutInflater infalInflater = (LayoutInflater) this._context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = infalInflater.inflate(R.layout.house_hold_list_row, null)
          TextView lblListHeader = (TextView) convertView
                .findViewById(R.id.house_hold_name);
        lblListHeader.setText(model.name);
        }

张贴右布局图。房屋保留清单_row@ADM我补充说，错误日志清楚地表明，行xml文件的textview id中没有匹配项。请先自行检查。此xml中不存在house\u hold\u list\u行，可能是因为复制粘贴。使其正确文本视图的id我检查了@ADM，但有相同的错误为什么会这样？它如何修复在
inflate（）
调用中抛出的
InflateException
？这甚至不会编译，因为
lblListHeader
超出了
if
块的范围。可能是您的条件没有按您想要的那样工作，所以首先检查“if”条件是否正常工作，更好的方法是尝试删除“if”条件……我检查了OMI
