Hide and Show views in ListView Android

Question

I have created and android application in that I want to hide and show views in ListView using Custom Adapter.

My Code is:

@Override
public 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;
}

enter image description here

When click on Dots it not hides the layout.

Thanks.

Yes, I have faced the same problem and solved it using ExpandableListView. I am pasting the code below

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;
    }
}

Override your click listener with this

btn_dots.setOnClickListener(new OnClickListener()
    {
        @Override
        public void onClick(View arg0)
        {
            if (arg0.getVisibility() == View.GONE)
            {
                arg0.setVisibility(View.VISIBLE);
            }
            else
            {
                arg0.setVisibility(View.GONE);
            }
        }
    });

One line : `(arg0.getVisibility() == View.GONE) ? arg0.setVisibility(View.VISIBLE : View.GONE);` – Pratik Butani Dec 18 '14 at 06:55
you can use this alternate way also :) – Amit Thaper Dec 18 '14 at 06:56
With Less character one line: `arg0.setVisibility(arg0.getVisibility() == View.GONE ? View.VISIBLE : View.GONE);` – Pratik Butani Dec 18 '14 at 06:57
@ツFellinLovewithAndroidツ :) He is trying to hide another view, not the button. And using if-else you make your code more readable than using turnary operators. – Pankaj Kumar Dec 18 '14 at 07:15

You can do like this in one line code:

btn_dots.setOnClickListener(new OnClickListener()
{
    @Override
    public void onClick(View arg0)
    {
        arg0.setVisibility(arg0.getVisibility() == View.GONE ? View.VISIBLE : View.GONE);
    }
});
