在ListView Android中隐藏和显示视图

我已创建和Android应用程序,我想隐藏和使用自定义适配器在ListVIEw中显示视图.

我的代码是：

@OverrIDepublic VIEw getVIEw(final int position, VIEw convertVIEw, VIEwGroup parent){    LayoutInflater inflater = (LayoutInflater) context            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);    VIEw vi = convertVIEw;    if (convertVIEw == null)    {        vi = inflater.inflate(R.layout.item_estimate, null);        btn_dots = (Imagebutton) vi.findVIEwByID(R.ID.btn_dots_itemEstimate);        ll_2 = (linearLayout) vi.findVIEwByID(R.ID.ll_2_itemEstimate);    }    btn_dots.setonClickListener(new OnClickListener()    {        @OverrIDe        public voID onClick(VIEw arg0)        {            if (ll_2.getVisibility() == VIEw.GONE)            {                ll_2.setVisibility(VIEw.VISIBLE);            }            else            {                ll_2.setVisibility(VIEw.GONE);            }        }    });    return vi;}

点击Dots时,它不会隐藏布局.

谢谢.

解决方法:

是的,我遇到了同样的问题并使用ExpandableListVIEw解决了它.我正在粘贴下面的代码

public DefaultContactlistadapter(Context context, ArrayList<Cont> List2) {    super();    this.context = context;    this.contactList = contactList2;    @OverrIDe    public Object getChild(int parent, int child) {        return child;//      return glossarIEsList.get(Sub_List.get(parent) ).get(child);    }    @OverrIDe    public long getChildID(int parent, int child) {        // Todo auto-generated method stub        return child;    }    @OverrIDe    public VIEw getChildVIEw(int parent, int child,            boolean lastChild, VIEw convertvIEw, VIEwGroup parentvIEw)    {//      String child_Title=(String) getChild(parent, child);        if(convertvIEw==null)        {            LayoutInflater inflator=(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);            convertvIEw=inflator.inflate(R.layout.layout_default_contact_screen_child, parentvIEw, false);        }        return convertvIEw;    }    @OverrIDe    public int getChildrenCount(int groupposition)    {        return 1;    }    @OverrIDe    public Object getGroup(int groupposition) {        // Todo auto-generated method stub        return contactList.get(groupposition);    }    @OverrIDe    public int getGroupCount() {        // Todo auto-generated method stub        return contactList.size();    }    @OverrIDe    public long getGroupID(int groupposition) {        // Todo auto-generated method stub        return groupposition;    }    @OverrIDe    public VIEw getGroupVIEw(int parent, boolean isExpanded,            VIEw convertVIEw, VIEwGroup parentvIEw) {        // Todo auto-generated method stub        //String group_Title=(String) getGroup(parent);        if(convertVIEw==null)        {            LayoutInflater inflator=(LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);            convertVIEw=inflator.inflate(R.layout.layout_default_screen, parentvIEw,false);        }        return convertVIEw;    }    @OverrIDe    public boolean hasStableIDs() {        // Todo auto-generated method stub        return false;    }    @OverrIDe    public boolean isChildSelectable(int groupposition, int childposition) {        // Todo auto-generated method stub        return false;    }}
