Ok, 因此,我写了一部可扩展的ListView和下级可扩展的ListAdapter。 除我外,一切工作都很出色,在被点击时不能让儿童的意见得到重视。 如果我使用双轨制,一切都会奏效。 但是,如果我试图点击一名儿童,我就得不到任何反馈。

我尝试了确定甲状腺和甲状腺:在TouchMode和甲状腺可溶解剂(我也尝试通过密码确定这一点),但我可以找工作。 任何想法?

我的《适应者守则》:

public class ExpandableAppAdapter extends BaseExpandableListAdapter
{
    private PackageManager m_pkgMgr;
    private Context m_context;
    private List<ApplicationInfo> m_groups;
    private List<List<ComponentName>> m_children;

    public ExpandableAppAdapter(Context context, List<ApplicationInfo> groups, List<List<ComponentName>> children)
    {
        m_context = context;
        m_pkgMgr = m_context.getPackageManager();
        m_groups = groups;
        m_children = children;
    }

    @Override
    public Object getChild(int groupPos, int childPos) 
    {
        return m_children.get(groupPos).get(childPos);
    }

    @Override
    public long getChildId(int groupPos, int childPos) 
    {
        return childPos;
    }

    @Override
    public int getChildrenCount(int groupPos) 
    {
        return m_children.get(groupPos).size();
    }

    @Override
    public View getChildView(int groupPos, int childPos, boolean isLastChild, View convertView, ViewGroup parent) 
    {
        if (convertView == null)
        {
            LayoutInflater inflater = LayoutInflater.from(m_context);
            convertView = inflater.inflate(R.layout.expandable_app_child_row, null);
        }

        ComponentName child = (ComponentName)getChild(groupPos, childPos);
        TextView txtView = (TextView)convertView.findViewById(R.id.item_app_pkg_name_id);
        if (txtView != null)
            txtView.setText(child.getPackageName());

        txtView = (TextView)convertView.findViewById(R.id.item_app_class_name_id);
        if (txtView != null)
            txtView.setText(child.getClassName());

        convertView.setFocusableInTouchMode(true);
        return convertView;
    }

    @Override
    public Object getGroup(int groupPos) 
    {
        return m_groups.get(groupPos);
    }

    @Override
    public int getGroupCount() 
    {
        return m_groups.size();
    }

    @Override
    public long getGroupId(int groupPos) 
    {
        return groupPos;
    }

    @Override
    public View getGroupView(int groupPos, boolean isExpanded, View convertView, ViewGroup parent) 
    {
        if (convertView == null)
        {
            LayoutInflater inflater = LayoutInflater.from(m_context);
            convertView = inflater.inflate(R.layout.expandable_app_group_row, null);
        }

        ApplicationInfo group = (ApplicationInfo)getGroup(groupPos);
        ImageView imgView = (ImageView)convertView.findViewById(R.id.item_selection_icon_id);
        if (imgView != null)
        {
            Drawable img = m_pkgMgr.getApplicationIcon(group);
            imgView.setImageDrawable(img);
            imgView.setMaxWidth(20);
            imgView.setMaxHeight(20);
        }

        TextView txtView = (TextView)convertView.findViewById(R.id.item_app_name_id);
        if (txtView != null)
            txtView.setText(m_pkgMgr.getApplicationLabel(group));

        return convertView;
    }
    @Override
    public boolean hasStableIds() 
    {
        return false;
    }
    @Override
    public boolean isChildSelectable(int groupPos, int childPos) 
    {
        return true;
    }
}

提前感谢!
