Idea on implementing the following pop up menu in ListView

问题

I would like to have pop up menu, when I click on the 3 dots area in a ListView row.

registerForContextMenu won't meet my need, as it happen during long press, in any area of ListView row.

I would like to know.

How to create a 3 dots looking UI in ListView row?
How to have PopupMenu, even for Android 2.3?

回答1:

You can use ImageView to display image with 3 dots.
There are two ways for popupmenu

a) Use some layouts and make them visible/gone

b) Use PopupWindow.

here is sample code for PopupWindow

PopupWindow popupWindow = new PopupWindow(context);

View popUpView = View.inflate(activity, linearlayout, null);
popUpView.setBackgroundColor(Color.TRANSPARENT);
mpopup.setContentView(popUpView);
mpopup.setHeight(LayoutParams.WRAP_CONTENT);
mpopup.setWidth(LayoutParams.WRAP_CONTENT);
mpopup.setFocusable(true);
mpopup.setBackgroundDrawable(activity.getResources().getDrawable(R.drawable.transperent));
mpopup.setOutsideTouchable(true);
mpopup.setAnimationStyle(R.anim.slide_out_up);
mpopup.showAtLocation(popUpView, Gravity.TOP, activity.getResources()
            .getInteger(R.integer.log_out_popup_x), activity.getResources()
            .getInteger(R.integer.log_out_popup_y));

I know its a bit late and you probably may have found a solution but i just came across your question and here's my solution...

Below is my code of the getView method of the Adapter class...

@Override
public View getView(int p, View convertView, ViewGroup parent)
{
    final ViewHolder holder;

    if (convertView == null)
    {
        holder = new ViewHolder();
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.d_item, null);

        holder.dHeading = (TextView) convertView.findViewById(R.id.txt);
        holder.ds = (TextView) convertView.findViewById(R.id.txt1);
        holder.options = (ImageView)convertView.findViewById(R.id.dPopupMenu);
        convertView.setTag(holder);
    }
    else
    {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.dHeading.setText(DList.get(p).getDHeading());
    holder.ds.setText(DList.get(p).getDs());

    holder.options.setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            final PopupMenu popmenu = new PopupMenu(context, holder.options);
            popmenu.getMenuInflater().inflate(R.menu.dua_popup_menu, popmenu.getMenu());

            popmenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener()
            {
                public boolean onMenuItemClick(MenuItem item)
                {
                    Toast.makeText(context, "You Clicked : " + item.getTitle(), Toast.LENGTH_SHORT).show();
                    return true;
                }
            });

            popmenu.show();
         }
     });

    return convertView;
}

Or you can show a dialog, when 3 dots clicked. PopupWindow need to locate where to show on the screen. Show a dialog can indentify witch cloumn you selected.
