Question

我用搜索视图制作了一个简单的可扩展列表视图我想祝酒词当我点击 child 项目时，它说项目 ID 已选中，但我不能

这是我的 class MyLislist 大洲是群体和国家 children

private Context context2;
private ArrayList<Continent2> continentList2;
private ArrayList<Continent2> originalList2;

public MyListAdapter2(Context context2, ArrayList<Continent2> continentList2) {
    this.context2 = context2;
    this.continentList2 = new ArrayList<Continent2>();
    this.continentList2.addAll(continentList2);
    this.originalList2 = new ArrayList<Continent2>();
    this.originalList2.addAll(continentList2);
}
@Override
public Object getChild(int groupPosition, int childPosition) {
    // TODO Auto-generated method stub
    ArrayList<Country2> countryList2 = continentList2.get(groupPosition).getCountryList2();
    return countryList2.get(childPosition);
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    // TODO Auto-generated method stub
    return childPosition;
}

@Override
public View getChildView(int groupPosition, int childPosition,
                         boolean isLastChild, View convertView2, ViewGroup parent) {
    // TODO Auto-generated method stub

    Country2 country2 = (Country2) getChild(groupPosition, childPosition);
    if(convertView2 == null)
    {
        LayoutInflater layoutInflater = (LayoutInflater) context2.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView2 = layoutInflater.inflate(R.layout.child_row2, null);
    }

    TextView name2 = (TextView) convertView2.findViewById(R.id.name2);
    name2.setText(country2.getName2().trim());

    name2.setTextSize(25);
    name2.setPadding(50,0,0,0);

    return convertView2;
}

@Override
public int getChildrenCount(int groupPosition) {
    // TODO Auto-generated method stub
    ArrayList<Country2> countryList2 = continentList2.get(groupPosition).getCountryList2();
    return countryList2.size();
}

@Override
public Object getGroup(int groupPosition) {
    // TODO Auto-generated method stub
    return continentList2.get(groupPosition);
}

@Override
public int getGroupCount() {
    // TODO Auto-generated method stub
    return continentList2.size();
}

@Override
public long getGroupId(int groupPosition) {
    // TODO Auto-generated method stub
    return groupPosition;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded,
                         View convertView2, ViewGroup parent) {
    // TODO Auto-generated method stub
    Continent2 continent2 = (Continent2) getGroup(groupPosition);
    if(convertView2 == null)
    {
        LayoutInflater layoutInflater = (LayoutInflater) context2.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView2 = layoutInflater.inflate(R.layout.group_row2, null);
    }

    TextView heading2 = (TextView) convertView2.findViewById(R.id.heading2);
    heading2.setText(continent2.getName2().trim());

    heading2.setTextSize(30);
    heading2.setPadding(20, 0, 0, 0);




    return convertView2;
}

@Override
public boolean hasStableIds() {
    // TODO Auto-generated method stub
    return true;
}

@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    // TODO Auto-generated method stub
    return false;
}

public void filterData(String query)
{
    query = query.toLowerCase();
    Log.v("MyListAdapter", String.valueOf(continentList2.size()));
    continentList2.clear();

    if(query.isEmpty())
    {
        continentList2.addAll(originalList2);
    } else {
        for(Continent2 continent2: originalList2)
        {
            ArrayList<Country2> countryList2 = continent2.getCountryList2();
            ArrayList<Country2> newList = new ArrayList<Country2>();
            for(Country2 country2: countryList2)
            {
                if( country2.getName2().toLowerCase().contains(query))
                {
                    newList.add(country2);
                }
            }
            if(newList.size() > 0)
            {
                Continent2 nContinent2 = new Continent2(continent2.getName2(), newList);
                continentList2.add(nContinent2);
            }
        }
    }

    Log.v("MyListAdapter", String.valueOf(continentList2.size()));
    notifyDataSetChanged();
}

}

这是我的 oncreate

enter code here
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maladbd);
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    search = (SearchView) findViewById(R.id.search2);
    search.setSearchableInfo(searchManager
            .getSearchableInfo(getComponentName()));
    search.setIconifiedByDefault(false);
    search.setOnQueryTextListener(this);
    search.setOnCloseListener(this);



    // display the list
    displayList();
    // expand all Groups
    expandAll();


}

只需将 setOnChildClickListener 添加到您的列表中，如下所示：

yourList.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
            @Override
            public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
                Toast.makeText(getApplicationContext(), "Your message", Toast.LENGTH_SHORT)
                        .show();
                return true;
            }
        });
